Market overview of import wheeled excavators. Wheel Excavators JCB JC130W, JC160W and JC200W

There are various types of excavators, depending on the principle of operation, the device chassis, destination and other parameters

Types of excavators on the principle of action

Excavators are divided into continuously working (multidimal) and cyclic (single-line).

The first associated with continuous work is used mainly when digging trenches. They are simultaneously cut into the ground, move it and ship into special transport, conveyor or dump.

The second, single-line, interrupt the soil digging at the time of movement. They are used mainly during construction, to perform major earthworks. In the appointment of single-line excavators, in turn, are divided into construction and careers. Career are used in places of development of mineral deposits.

Types of excavators by type of device

Wheel excavators . Based on a car wheel or pneumocole chassis. They are distinguished by mobility, high movement speed, wide use area. This technique is mainly used for work within the city, where there is an opportunity to get to the destination on a relatively good road.

Crawler excavators. Based on a tracked go. They are distinguished increased patency On the terrain inaccessible to the wheeled technology. These are loose sandy soils, off-road, overwhelmed swampy soil, etc. However, they are delivered to the place with the help of special equipment. In terms of sales, for example, tracked models exceed wheels by 15-20%.

Railway excavators Based on the railway platform, floating excavators - on pontoons. The latter are used for clearing water bodies, deepening bottom, sand mining.

The most sought-after types of special equipment and their appointment

Field-turn excavator on a wheeled or caterpillar - Universal view of special equipment used on construction sites. It performs earthworks on the development of the soil, the device of pots, loading bulk materials, leveling platforms, demolition of buildings and structures.

Mini-excavator - solution for cases when big car Not applicable or excessive.

Backhoe loader Performs the trenches, the development of kittlers, the movement of the soil, the loading of construction waste, clearing the territories, preparation of the base of the road for asphalting.

The use of additional equipment for excavators makes it possible to expand the functionality of special equipment. So, the excavator-loader combines the excavation-loading bucket with bulldozer equipment.

Excavators manufacturers

Dear, but very powerful and extremely reliable JCB, Caterpillar and Liebherr excavators are in demand on the primary market and retain their high cost when subsequent resale. Terex, Komatsu, Hyundai, Hydrema, Hidromek, Volvo, Case, John Deere, New Holland, Hitachi, Exmash are also considerably popular. Inexpensive Chinese technician Yuchai, Xcmg, Sunward, Liugon also in demand.

From ancient times, people were engaged in earthworks. Modern volumes of such procedures are simply colossal (construction, career, roads). Manually do all processes simply unreal and too long. Special technique comes to the rescue. Consider further what excavator is and what is his role in the industrial farm.

Introduction

Mechanization the process of developing land tried more than five hundred years ago Leonardo and many more scientists. Modern cars differ in many parameters, depending on the modification and direct destination. The main classification is carried out according to the following parameters:

• Type of running part (wheels, caterpillars, railway running and so on).
• Operational features (for construction, quarries, mines and the like).
• Power ungregate.
• According to the principle of action.

All these indicators can be combined in various variations, therefore a tremendous number of modifications under consideration are developed.

Crawler

What is an excavator on caterpillars? This is a machine that will pass on roads with any coating, as well as without it. The overwhelming majority of self-propelled excavator equipment is placed on the base with a crawler. The exceptions are analogues operating in the city. The models under consideration easily overcome loose soil, peatlands, off-road, forest and stone obstacles.

Other types of chassis

Excavators on pneumatic wheels have greatly proven themselves to work in urban conditions. Crawler analogs are not suitable here because they will simply destroy asphalt coating. Wheel models are not only gentle related to road design, but also perfectly imputed, and also have a minimum noise level.

What is a stepping type excavator? Such a modification is devoid of caterpillars or wheels. At the bottom of the unit is the support plate, which serves as a platform when working. Machine is moved using special hydraulic shoes. She rises to them, transfers itself and again falls on the support plate. Speed \u200b\u200bmode Movement can be up to 80 km / h.

Excavators on the rail move are usually operated in mining workings. Chain models are placed on rails widely located. This distance is called the portal, it is convenient to call for loading trucks into it.

Earthwall universal devices can be mounted almost on any chassis. Combined modifications can be equipped with wheels and rails lowered pairs, if necessary, movement on rails. There are floating analogs (dredgers).

Operating principle

Single-line variations work in cyclic mode: scored - transferred - poured. Continuous fixtures include rotary and trench excavators. To the first models, units with multiple buckets are counted, which are fixed on a large rotating wheel. As an example of a trench analogue, light units for laying the cable can be brought. Domesticities are gaining sand under water by vacuum-suction principle.

It is impossible to determine one optimal and universal way of work. It all depends on the type of material produced and environmental conditions. In each case, a specific type of equipment is required.

Features

Excavator overview will continue wheeled models for construction. Despite the fact that tracked modifications are leading in the field of soil development, for construction sites optimal option Wheel aggregates. They are more mobile, more speed, do not spoil asphalt and are promptly transferred from one to another object.

Shaft excavators have compact dimensions, which is relevant in closed spaces. As a rule, they are used in horizontal workings underground and in tunnels for shipment of rocks.

An open career is operated by modifications that can provide maximum movement and loading material. There are several types of machines in such works. The main requirement for them is that the excavator bucket is as compatible as possible. Among the career models:

• Draglains. The design of these aggregates does not provide for a rigid bucket with an arrow. The scoop is held with the chain, the analogue of which pulls up or lowers it.
• Tracked high passability.
• Hydraulic versions with the ability to enhance the pressure impact on the breed. Usually apply on overcurrent work.
• Modifications rotor typeproviding maximum full use of minerals.

Power plants

The study of the technical characteristics of the excavator will continue in part of the engines. The first machines worked from the steam engine, then removal, gasoline and electric motors came to replace them. The most popular power units are Diesel and are due to their economy.

The diesel version is mobility. This technique allows a lot to move along the object being processed and beyond. If the process involves moving on small distancesIt is reasonable to use an electrical analogue. For career workings, this technique is suitable.

The development of light excavators that feed on rechargeable batteries. In this case, the machine is controlled by the operator remotely or in the traditional way.

Application

What is an excavator and why is it needed? First of all, the technique under consideration is an excavation machine, the main task of which is the excavation, the transfer of the soil and rock. At the same time, excavators can work not only on sites where there are, but also in areas, the level is lower or higher. In addition, the material can be mined without problems from under the layer of water.

The resulting breed of equipment loads into transport units (machines, barges, wagons). If necessary, the ground can be squeezed into the dump. The hydraulic excavator allows you to quickly and efficiently provide digging channels, trenches, butt, clearing the territory with maximum accuracy. The cars under consideration made it possible to fully mechanize earthworks, facilitating the essential labor of people. The ordinary construction model is capable of transferring up to 4 cubes of the Earth or sand for one approach.

The biggest excavators

The most in the category under consideration has impressive dimensions. The giant was developed and assembled by the German company THYSSEN Krupp Fordertechnik in 1978. The technique was gathered for 5 years, its cost exceeded 100 million euros. "Monster" worries so far in the coal section of the Hambaha.

The machine is functioning about 20 hours a day, performance - 240,000 cubic meters. m coal. Such volumes are quite difficult to load and remove, but this is not required. Such large excavators are required to extend the mass in which more than half of the material is an unsuitable breed. Giant dimensions: Length / Width / Height - 240/46/96 m. Mass - 13.5 thousand tons. The length of the arrows is 200 m. The volume of each bucket is 6.6 cubic meters. m.

Hitachi Excavator

Below are given technical specifications One of the most productive excavators - "Hitachi ZX200":

• Length / width / height - 8.94 / 2.86 / 2.95.
• Weight - 19.8 tons.
• Base wheel - 3.37 m.
• Clearance - 45 cm.
• Pressure on the soil - 0.47 kg / sq. M. cm.
• Development depth - 6.05 m.
• Excavator bucket volume - 0.51 cubic meters. m.
• Terminal force - 203 kN.

Silence unit "Hitachi ZX200"

The technique is equipped with four-stroke diesel engine with 4 cylinders. Motor has a direct fuel injection, camshaft In the upper placement and cooling of water type. New excavators of this modification are equipped with a power plant that aggregates with modern system HIOS III hydraulics, providing the ability to program manual and automatic operation. In addition, this unit makes it possible to maximize the use of hydraulic pressure, increasing the production of the cost-effective consumption of fuel.

Main engine parameters:

• Volume work - 5.19 liters.
• Power Nominal - 166 horse power.
• Torque maximum - 550 nm.
• The size of the cylinder in diameter is 105 mm.

Device

Equipped with an arrow (length - 5.68 m) and handle with increased traction force and turning point (2.91 m). Designers upgraded the movement control, resulting in the engine speed in automatic mode during maneuvers or on the rise when an increased traction force is required.

The dimensions of the brackets on the upper supporting rims are increased. This positively affects the working resource of the node. Additional rigidity to the unit gives a modified configuration and increasing tracks. In addition, the box of the box cross section and the central beam of the X-shaped type are increased. The whole complex of improvements added almost 35% to the strength. The plates of the X-shaped beam are made in the form of monolithic elements, which made it possible to significantly strengthen the central part of the frame.

Outcome

Modernization and constructive improvement of excavators is aware of continuous mode. Designers continue to achieve improved quality of work, which is due to the growth in the volume of construction and mining.

If you are the science leader or just an inquisitive person, and you often look or read the latest news in science or technology. It was for you that we created such a section where the latest world's news in the sphere of new scientific discoveries, achievements, as well as in the field of technology. Only the most recent events and only proven sources.

In our progressive time, science is moving rapidly, so it is not always possible to keep track of them. Some old dogmas rushes, some new ones are put forward. Humanity does not stand still and should not stand, but the engine of mankind is scientists, scientific figures. And at any time, the discovery may occur, which is capable of not just to hit the minds of the entire population of the globe, but also to change our lives in the root.

A special role in science is allocated medicine, as a person, unfortunately, is not immortal, fragile and very vulnerable to all kinds of diseases. Many people know that in the Middle Ages, people lived on average 30 years old, and now 60-80 years old. That is, at least half the life expectancy increased. This was affected, of course, a combination of factors, but medicine brought a big role. And, for sure, 60-80 years for a person is not the limit of average life. It is possible that someday people will overtake through the mark of 100 years. Scientists from around the world are fighting for it.

Development are constantly underway in the field of and other sciences. Every year, scientists from around the world make small discoveries, slowly promoting humanity forward and improving our lives. The places who are not touched by a person, first of all, of course on our native planet. However, work in space is constantly working.

Among the equipment is especially robotics. The creation of an ideal reasonable robot is underway. Once upon a time the robots were an element of fiction and no more. But at the moment, some corporations have in the staff of real robots that perform various functions and help optimize labor, save resources and fulfill dangerous activities.

I also want special attention Decide electronic computing machines that have occupied a huge number of 50 years ago, were slow and demanded a whole team of employees for their care. And now such a car, almost, in every home, it is already called it easier and shorter - a computer. Now they are not only compact, but also at times faster than their predecessors, and everyone can understand it. With the advent of a computer, humanity opened a new era, which many call "technological" or "information".

Remembering the computer, do not forget about creating the Internet. This gave a huge result for humanity. This is an inexhaustible source of information, which is now available to almost every person. He binds people from different continents and lightningly transfers information, it was impossible to even dream about this year 100 ago.

In this section, you will definitely find something interesting, fascinating and informative. Perhaps even someday you can be one of the first to learn about the discovery that will not just change the world, but will turn your consciousness.

The extraction of coal, manganese, ores containing metals, other minerals is associated with the movement of large volumes of rocks, drill and explosive work, and is produced all year round. For this heavy, in all senses, an appropriate technique is necessary. Opening deposits and subsequent recess of minerals with subsequent loading on a special car or railway transport Specialized type of excavators - career.

As it is clear from the name, career excavators are used, extracting minerals in open developments, performing overnight work. These machines are designed taking into account operation in a wide variety, including hard, climatic conditions, with different types Soils are intended for intensive use. Without such excavators, do not do on mining developments in the coal industry, on the extraction of building rocks, in color and ferrous metallurgy.

Power, fitness to long-term, including round-the-clock, work, high efficiency, the possibility of using electricity for the functioning of such equipment - distinctive feature These earthmoving mechanisms.

Device

The modern career excavator consists of a number of functionally complete structural nodes, allowing to efficiently maintain and repair them. The following functional parts can be given:

• Rama with caterpillars.
• Two-legged stand.
• Lower frame.
• Rotary platform.
• Body.
• Arrow with handle.
• Ladle.

Much attention is paid to the working place of the operator. Cabins are installed good overview, vibro- and soundproofed, with heating and air conditioning systems, ergonomic controls, control systems for the efficiency of the excavator.

Classification

Career excavators can be classified with such signs:

• Type of chassis: Crawler, walking.
• Principle of operation: cyclic action (single-loving) and continuous operation (rotary).
• The type of engine used: diesel, electrical, single-engine or multi-motor.
• Drive type: hydraulic, hydromechanical, mechanical, electric, etc.

It is customary when choosing to be guided by the principle that is optimal - to load the career dump truck for 4-6 working cycles of the excavator used.

Crawler

This type of excavators are divided into several types by the number of caterpillars installed on the platform: two-, four- and eight-dimensional. As working devices, reverse or straight buckets with a capacity of up to 50 m3 and more are used.

Stock Foto Crawler Career Excavator

Rotor

These excavators may be tracked or walking. At the end of the boom is a rotary rotary wheel on which the buckets are fixed. The volume of each of them can reach 6 m3. The arrow itself can be both retractable and non-sensitive. Rotary and dump arrows can rise and descend. Range of action when developing breeds up to 50 m and up to 25 m in depth.

Rotary career excavator

In motion, such an excavator is driven by an electric motor.

Hydraulic

This is one of the most common types of excavation techniques used in the extraction of ores, minerals in careers. These machines are used for loading breeds in transport.

Excavators of this type are equipped with rushes of direct and reverse types. Diesel engines or electric motors are installed.

Hydraulic career excavator

Walking

This type of excavators can often be found in overnight work, in most cases they are equipped with draglin. His name - walking - received from the method of movement. In the working position, the excavator comes into contact with the soil with the help of a support frame. When there is a need for a location change, the support "skis" are put forward, the excavator is raised on the hydraulic rods, moves to a certain distance (makes "step") and again falls on the frame.

Walking career excavator

Given the high weight of such mechanisms to hundreds and thousands of tons, this design allows you to achieve a low pressure pressure on the ground, which would be impracticable when using a tracked propeller. The length of the boom can reach 100 m, and the volume of the bucket - exceed 100 m3.

█ The world's best mini excavators. Buy and choose. (Top 10 Overview)

Mini excavator is small and pretty easy machineallowing you to quickly reach the construction site. However, despite compactness, the technique becomes a real assistant in organizing earthworks. To date, the development of hydraulic systems, improved specifications Allow mini excavators to get closer as much as possible, and in some cases surpass their senior fellow.

In certain situations, and on a number of specific construction sites, we can play on hand not only a small weight of a small excavator, but also its compactness that directly affects its maneuverability and accuracy in work. For example, on narrow urban streets, in low-rise (cottage) buildings, with the foundation of the foundation on aesthetic garden lawn. Mini excavators with the so-called "zero crash" (Zero Tail Swing) will allow you to work in a limited space without clinging for obstacles. In addition, the low mass of the machine will save your lawn and other elements of landscape aesthetics. Unfortunately, in the case of imported mini excavators, including a problem with the cost of customs clearance, a utilization fee, which in turn does the price of the transcendental price. Business on a mini excavator is an interesting thing, and if you go with the mind, you can work well. So what mini excavator is better?

Mini-excavator: what to pay attention to when choosing?

Despite the fact that among earthmoving equipment, the mini-scabers are the most compact, their mass is quite significant. This class of technology includes cars up to 10 tons. Despite the external similarity with heavier models, their functions can sometimes seriously differ from the "giants". We turn to the parameters of this type of technology, which first of all it is characterized.

-Configuration arrows and cabins

The excavator arrow is attached directly to the housing of the excavator or its cabin and keeps the shoulder with the bucket and mounted equipment. There are different configurations of the fastening of the boom. For example, if the boom is fixed, it is attached directly to the excavator housing, and moves only when the machine turns. If the arrow is moving in a horizontal projection - it gives greater mobility and maneuverance when digging.

In addition, there are three options for departure of the tail of the cab of a mini excavator: zero (zero crawling cabins), minimal departure and full departure. The technique with a complete departure is hard to use in a limited space. On the contrary, the system with zero crash of the tail of the cab is ideal for a limited space. Although cabins with minimal departure give a good result when maneuvering in a closed space.

- Engine power and cab design

The mini-excavators are mainly installed diesel engines, the power and the definition of which in turn determine challenges, as well as strength and hydraulics. In addition to the power of the engine in L.S. (kW), matter the number of cylinders and torque. Mini excavators' cabins are open and closed. Of course, the closed cabin is more popular, as it protects the operator from bad weather, dust and dirt on a construction site, however, the cost of such models is in most cases higher.

- Chassis and caterpillars

It should be noted that the overwhelming majority of mini excavators have caterpillars as a propulsion (with the exception of a narrowly specialized segment of non-intelligent towed trailed mini-excavators, which we have written earlier.

Caterpillars are installed rubber and steel. Both species of caterpillars have its advantages and disadvantages. For example, steel caterpillars provide greater patency and have greater strength. However, rubber (due to its relative softness) causes less harm to the lawns, sidewalks, a blocking with landscaped work. The chassis is under the excavator body, leading to the traffic of the caterpillar and the car.

The chassis in small excavators is two types: fixed and movable. The first is significantly wider than the excavator housing, which gives additional stability. Nevertheless, in some cases, this parameter will limit maneuverability and mobility in closed spaces. The movable chassis makes it possible to change the wheelbase with the help of hydraulics, narrowing it to the width of the machine housing.

- Hinged equipment

In addition to the wide range of lubricated size and shape, the operator can use attachments operating from the excavator hydraulic system, such as a yamobur or drilling rig with various augers, a hydraulic hammer for crushing stone, asphalt or beto, and another hitch. Special cargo plugs are also used to move logs, stones, construction trash. In addition, sometimes the mini excavator is used as a mini-crane.

If your choice fell on a mini excavator, and you want to buy or take it for rent, leasing, credit, this technique will pleasantly surprise you with your capabilities. As mentioned above, such a car will show itself well on narrow streets and will retain a lawn by performing a wide range of earthworks.

And if you are limited in the budget and can not afford new techniquethen our review will help you on how to choose a mini excavator bu.

Mini Excavator Bobcat E32I T4

This model is a traditional mini-excavator with tail reversal. It is available in three configurations: standard, with an elongated arrow and with a sliding arrow.

This unit has a mass of 3260 kg in the configuration with the base boom. Base version dimensions make up: 4.66 meters - length; 1.52 meters - width and 2.43 meters - the excavators are set by a diesel engine with a capacity of 24.8 hp. At maximum turns of 2200 per minute. More loaded versions with an elongated and sliding arrow are equipped with turbocharged power units due to the increased mass of the machine.

The speed of the described model of the mini-excavator is 4.5 km / h. The angle of rotation of the boom is 75 degrees left and 55 degrees to the right, which is associated with the design of the rotary hinge. The depth of digging varies from 3.1 meters to 3.9 meters depending on the arrow design in the version you selected.

All three versions in the standard layout are offered to buyers with rubber tracks, but the option of installing steel tracks is available for wanting. As previously mentioned, the unconditional advantage of rubber caterpillars is their "anti-vandality" on lawns, a fragile blocking and on some other surfaces. However, steel caterpillars give better permeability and by themselves significantly exceed rubber threatening and durability.

The mini-excavator Bobcat is offered in versions with an open cabin with a roof or with a fully closed cab. The cabin has air conditioning with a stove, radio, comfortable seat. The dashboard informs the operator about the engine speed, the coolant temperature, there is a fuel level indicator, a meter meter and so on. As an option, it is possible to install a more technological dashboard with a color display, invincible launch and a throttle position indicator.

The perfectly developed hydraulic system of the E32I machine provides a calm and smooth management of the technique, allows you to safely switch between different functions in accordance with the mounted mounted on arrow (for example, a hydrobur, hydraulic hammer and so on). The hydraulics control mode is determined by the operator of the mini-scale, based on the installed equipment and allows the machine to respond differently to the movement of the pilot joystick.

Bobcat offers various types of hits. It is a boring, buckets of various types and sizes, a bump, a special grasp for logs and construction waste, bulldozer dump, hydraulic scissors and others. Quick disconnect hydraulic connections and the X-Change Bobcat system will allow you to comfortably and quickly replace the necessary attachments.

The E32I model with an elongated arrow certainly gives additional opportunities to the mini-scale, however, the standard tail departure of these models limits the maneuverability of the car, in contrast to the models of competitors with a minimum or zero tail departure.

Mini Excavator Caterpillar 301.5

The described model is mini-excavators of the so-called starting (initial) level. This mini-excavator weighs 1672 kg. It is easy and compact, can work on easy-damaged surfaces (lawn, paving), as well as under the tilt up to 30 degrees, which certainly gives additional features. The gearbox has two speeds reaching 2.25 km / h and 4.34 km / h, respectively. Obviously, the first speed is essentially a worker, and to move on the workplace from the object to the object it is more convenient to switch to the second, unless of course "accelerate" will allow the landscape. In addition, the presence of two speeds allows you to use a variable of craving depending on the type of surface and the properties of the soil.

The machine has a 17,4-strong diesel atmospheric power unit Caterpillar 3003 with water-cooled, having 4 cylinders reaching 2,200 revolutions per minute.

The arrow has such an angle of rotation at which the operator is perfectly visible to the digging process. Cat 301.5 has a standard tail departure of a cab hanging over caterpillars. With the length of the caterpillar of 1.4 meters, a significant crash departure can interfere with working in a limited space.

The buyer proposes two options for the operator space of the operator - this is an open canopy and a closed full-fledged cabin. In Oyah, options are provided with robic hanger, glove box, working sensors and indicators on dashboard. The seat is available in two versions - vinyl and fabric. Obviously, the vinyl seat is more resistant to nature whims and is suitable for a vest with a canopy. On the contrary, a more comfortable fabric seat is an option for a closed all-weather cockpit. Of course, the more expensive version of the mini-excavator from the cabins has additional options, in particular: the stove, defrostor, internal lighting and wiper. There are no some options available for competitors, for example, no air conditioner, radio, invincible start, color screen. However, whether such "grazers" are needed in a shredder - a big question.

The model provides the use of additional attachments. These include various types of buckets, borants, hydraulic bumps. Additional hydraulic equipment is the original, called Quick Coupler Caterpillar. However, this "Origality" will not compromise you without refinement to connect freely optional equipment Funny from the brand Cat.

Model 301.5 is not among competitors the easiest or most powerful, but its strength is enough to close to the performance of full-sized machines, and its relative ease will allow you without fears to drive an excavator to your well-kept country site with landscape design. Its substantial disadvantage, as mentioned above, is a significant cabins. However, this constructive feature is characteristic of many other concerns of neighboring brands.

Mini excavator Hitachi ZX10U-2

The model is a small excavator with a zero craft tail (Zero Tail Swing), the Yanmar motor and the width of the caterpillar database. This is a rather lightweight excavator weighing a little more than 1,100 kilograms, which has the following dimensions: 2.96 meters - length and 1.46 meters - width.

This little excavator carries a powerful turbocharged Yanmar brand engine. The diesel power unit has three cylinders, reinforced turbine. Engine volume - 845 cm3, Power - 12.7 hp, Maximum revs - 2100 per minute. Such parameters of the power plant allow you to reach a speed of 4 km / h, while the speed of movement is 2 kilometers per hour. The fuel supply in the tank is 19 liters, the hydraulic system has a volume of 25 liters.

Hitachi ZX10U-2 has a radius of an electric cabin of a cab of 0.8 meters, which makes it possible to attribute it to the technique with zero departure of the cab tail, because with such parameters, the cab does not go beyond the gabarite of the tracked propeller. As it was said in joining our review, such a configuration is ideal for working between walls, trees, that is, in any limited space. In addition, this convenience is complemented by an adjustable width of the tracked base, which allows changing the actual width of the machine from the maximum one - 1 meter, to the minimum - 90 centimeters. Of course, a wider base gives greater stability, but in some cases, for example, if necessary, drive into a narrow doorway, this function is simply indispensable.

This mini-scab is quite limited by the amenities of the operator. The car does not even have a canopy, not to mention a full-fledged closed cabin. In stock Only the rear folding safety arc. With such features, keep in mind that protection against bad weather and building dust is essentially absent, which is quite essential for Russian latitudes.

From the facilities of the pilot there is a safety belt, a 12 volt socket, backlight. There is no stove and air conditioning, no radio, no hangers for working clothes. There is not even a cup holder. In fact, in addition to levers (joysticks), pedals and triggers, there is only an analog dashboard in the operator space. Dumping the excavator is adjusted mechanically and does not have a hydraulic line. The machine has the driving part of the tractor type on the rubber-tracked propulsion, which is convenient when working on an easily damaged surface - a lawn, pavement, paving. The chassis has three supporting rollers.

With a significant lightness of this excavator, the Hitachi model does not have a lack of power, and the zero wave of the tail of the cockpit allows you to work in a closed space. In addition, the variable latitude of the base allows you to pass especially narrow areas on a construction site. The excavator rental is most likely to be cheaper, since the car is easily transported in a simple passenger car. In fact, the only substantial disadvantage of this Japanese excavator is essentially the lack of any amenities of the operator of this mini-excavator, however, the price of a mini-excavator greatly wins in the fellow.

Mini Excavator John Deere 50G

This mini brand excavator John Deere. It has a mass of 4790 kg, which is not so little for the excavator of this class. However, this feature is more than compensated by a spacious and comfortable cabin of the operator, large and efficient working tools, as well as the powerful railway engine of the world leader Yanmar.

Reverse our gaze on power installationInhaling life into it is pretty heavy among the constructions. So, this is a diesel engine yanmar with a volume of 1.6 liters, having 4 cylinders, corresponding to all global environmental and technical standards and related to the class of heavy engines. This unit provides 36 "horses" forces at 125 Newton / meters of torque and revolutions up to 2400 per minute.

From the power of the engine, other features flow, in particular, despite the fairly large mass of the excavator, it has a rather greater speed, which "classmates" of our hero are unlikely to boast. On this compact excavator, you can ride with the breeze, disperse up to 6.77 km / h. At the same time, its minimum speed is 4.18 km / h, which exceeds maximum speed Any close analogue.

We pay special attention to the tail departure of mini excavators, which in our case is zero (or minimal, depending on the configuration), which, you see, for such an impressive car is extreme an important indicator. This reduces the risk of damage to the tail of the cockpit at the construction site, and also allows our mini-special scavenger to maneuver in a limited space.

Rubber caterpillars are installed on John Dir 50G, but unlike analogues, they carry steel cores, which significantly increases their service life. At the same time, the rubber propulsion retains all its advantages on a gentle lawn or a historical fragile blocking. This is especially true, given the mass of our hero - almost 5 tons! In addition, it is possible to install pure steel tracts, but it is better to do not go to the lawn with them without anything needed. There is also a variant of steel caterpillars with rubber softeners.

Comfortable cabin is just our case, because 50G carries all the amenities necessary to the operator. "Steering cutting" is spacious, has a comfortable entrance, anti-skid wrapping. There is a cup holder, a 12-volt "cigarette lighter", climate control (!) And display, showing hours, as well as sensors-indicators of the engine level and hydraulic oil. In the cockpit, both mechanical and hydraulic control of the machine is present.

The compact excavator has control levers with a short convenient move, the arrow of the pendulum type and folding pedals, a reduced transmission lever and other amenities within reach. For the installation of mounted equipment, the mini excavator has an original BRS system, which unfortunately allows you to work only with brand hits John Dir.

In conclusion, I would like to say that the mini excavator John Deere 50G is a powerful multi-functional apparatus, which in its functionality and capabilities closely close to the class of large excavators, in fact, rather to the middle of the size class of midi excavators (Mini Excavator Strong & Heavy ). Its absolute versatility attracts attention. For this, there is a powerful engine, and the zero taking of the tail of the cabin, rubber or steel tracks. However, its size, mass and cost is still great for a compact excavator. But if you still solved this mini excavator to buy, and not take, for example, for rent, you will not regret it. This is a great car!

Mini Excavator Kobelco SK35SR-5

The Kobelco SK35SR-5 mini excavator is a small excavator with a zero tail departure, equipped with the Yanmar engine. This apparatus has a complete set with a canopy and a full-fledged cab.

Its mass is 3580 kg in version with a canopy and 3720 kg from the cab. Machine dimensions: length - 4.72 meters, height 2.56 meters. Volume fuel tank 45.5 liters tank, the volume of the hydraulic system is also 45.5 liters. If you compare this excavator with most of the other ministers, it is rather heavy and very powerful for its category, belonging to the so-called category. Mini Strong & Heavy excavators.

This machine is aggregated by a three-cylinder four-stroke diesel engine with direct injection and water-cooled. This power unit issues 28.4 hp. With a revolving maximum 2400 / minute. The achieved power allows you to move on this heavy machine at a construction site at a speed of up to 4.5 km / h. In the usual mode of movement, the technician maneuver at speeds up to 2.6 km / h.

Thanks to the zero departure of the tail, the cabin of this mini excavator does not go beyond the body, which allows it to be freely rotated in narrow places, without fear of damage to the cabin and walls or trees. Arrow excavators slightly shifted from the center, which allows it to dig in parallel caterpillars without changes in the width of the caterpillar base. In such a layout, it is easier to cuddle to the wall and dig a trench with minimal maneuvering. The running part of SK35SR-5 is not regulated (fixed base in the width of the caterpillars), which may in some cases make it difficult to pass into narrow places.

You can buy a mini excavator with soft rubber tracks, as well as with steel trackers having special rubber inserts. The second option is essentially a compromise solution between softness and durability.

The excavator cabin has all the necessary amenities, such as a comfortable seat, seat belt, backlight, robic hanger and an additional armrest. However, it certainly lacks stoves, air conditioning and radio.

As shown by the practice of using this machine, the technique is reliable, unpretentious, copes with a wide range of tasks in cramped conditions. In fact, its only disadvantage is stability problems that are compensated by the presence of counterweights. The price of a mini excavator makes think about the feasibility of acquiring it. Look at how much mini excavator costs, and maybe you will satisfy alternative option - Rent a mini excavator. Or try to find such a device with mileage, but taking into account customs clearance, utilization collection, the valve can also bite. However, this dilemma is relevant for the majority of small excavators presented in our article.

Ultra-compact microexcavator kubota k008-3

Model K008-3 Ultra-Compact Weighs 997 kg. Its length is only 2.74 meters, height - 2.23 meters, width - 86 cm, which is generally a bit even for our compact family. This microxcavator is easy, agoned, but is quite powerful for small construction sites.

The width of the caterpillar base is regulated in the range from 72 to 86 cm. As already mentioned relative to other models of mini excavators of this class, the variable database of the propulsion is beneficial on maneuverability in doorways, between trees, in narrow corridors. You can also narrow off the excavator, making it in width less than the width of the caterpillar base, which will also add maneuverability to you.

A simple lever control system will allow you to easily switch from changing the width of the blade to the change of the width of the tracked base. The excavator is equipped with rubber tracks without the possibility of installing steel, which, on the one hand, together with its low mass makes it indispensable on the refined area, but on the other hand reduces the durability of the chassis (wear of rubber caterpillars).

Our mini-excavator is equipped with a three-cylinder diesel engine of 10 hp Of course, at first glance, such a minor power may seem insufficient to us, however, with such a small mass of the car, it is enough. The excavator has the ability to quickly access the radiator, the battery, fuel filter, coolant and air cleaner.

The K008-3 model has a two-speed transmission with traffic speeds: 2 and 4 km / h, respectively, each speed has a separate pedal. Technique comes without a cabin or canopy. There is a feeling that the Japanese on their excavators consider these options unnecessary, which we can observe both other excavators from the rising sun. As a security measure, there is a folding arc that does not have a roof. The dashboard itself has only a cooling fluid temperature indicator in the form of a warning lamp. Technique is certainly interesting, but will anyone want to buy a mini-excavator of too small and without special amenities for the operator when there are more powerful and productive competitors?

New Holland E18B CD

The small E18B New Holland excavator is a minimal cabin with a minimum crash. Comes in budget configuration with a canopy and in the top with the cab. The mass is about 1.8 tons, and what the model name is hinted transparently. Such a lot is unlikely to allow the delivery of a mini excavator to the object on the usual light trailer. Drive the excavator to the trailer on the dimensions you will be able, but if you will go so. Here you will obviously need a platform for the transport of a mini excavator or a passenger trailer auto transport. Dimensions from the cab: 235 cm - height and 365 cm - length.

Three-cylinder, four-stroke, diesel power unit Mitsubishi. With direct injection issues 15 horsepower at 2100 revolutions per minute. This distinguishes it from most fellow, preferring Yanmar engines. The hydraulic system accommodates 15 liters of oil and works under three pumps. The hydraulic motor installed on the reverse rotary device (crown) of the excavator allows 9 rpm. The angles of force turns relative to the cabin make up 80 degrees left and 45 degrees to the right.

A mini-excavator has a tracked propulsion (in basic configuration This is an excavator on rubber caterpillars). As repeatedly mentioned above, rubber caterpillars have anti-vandal properties that preserve the lawn or a blocking. In mathematical expression, the pressure of the excavator to the surface is one kilogram per square centimeter. However, the strength of the rubber tracked propulsion in comparison with the steel, leaves much to be desired. Replacing the caterpillars - not such a big problem. The main difficulty is their high cost. However, you can always find Chinese counterparts in the satellite. The base velocity is 3.54 kilometers per hour, but there is a reduced transmission - 1.8 kilometers per hour.

Unfortunately, it is necessary to recognize that the New Holland E18B is a rather slow excavator (both at the speed and speed of the tower). In addition, the presence of an departure of the cabin, albeit the minimum, shyles it in movements. However, the compactness and relative ease of the model will allow you to perform a wide range of earthmoving tasks. Of the advantages, it is possible to note the variable tracked database along the width (which is not unique for this segment of mini-equipment) - the transverse envelope will vary from 133 cm to 99 cm, however, when you reduce this parameter, you lose stability.

Of course, the version with a canopy differs in comfort from the "Cabin Modification", but the version with the cab does not have an air conditioner, racks for robes, work light, radio and seat belt. However, the window is not such a problem, but the stove, which is certainly installed in the cabin, will play an important role in Russian expanses. In addition, instead of the E18B dashboard, it has external hydraulic and fuel manometers. Hinged additional equipment on rapid drives (BRS) is provided by the manufacturer.

Cheap Buy such a mini excavator will not work. The price of the mini-exercavator on the official website must say, bite. The market for this technique will rather small. Maintenance will be not cheap, however, as well as all the models listed in the article. However, this is compensated by the high reliability of our kids.
