Mini excavators are becoming increasingly demanded among Russian consumers every year.
This technique, despite its modest sizes, has all the functional capabilities of its "senior counterparts" and at the same time has several advantages over them.
These include compactness, low weight, efficiency, simplicity of transportation to the place of work and relatively small cost.
Small sizes allow you to use mini excavators in a limited space, including on closed rooms where it cannot work large equipment. They are used when carrying out various construction and earthmoving work: digging of kittlers, trenches for laying pipelines and cables, arrangement landscape design plots, etc.
In today's market, special equipment is presented big choice Models of mini excavators of foreign manufacturers. But the cost of such equipment is high enough and largely depends on the firmware of the manufacturer.
Therefore, for many consumers, its acquisition becomes not affordable and alternative option It is an independent production of a mini excavator under its needs, which can significantly save spending on its acquisition.

Where to begin
The first step in the process of building a mini excavator is your own hands to define its type, which can be two main options:
In the form of removable attachments on the already existing special equipment, such as a mini tractor.
Fully autonomous model that can be self-propelled (on a wheel or caterpillar) or in the form of a trailer transported by other motor vehicles.
The advantage of the first option is the versatility of mini technician, which can perform various types of work by changing attachments. In the absence of such an opportunity, it remains to create an autonomous mini excavator.
It should be noted that the manufacture of a completely self-propelled model, especially on a tracked process, is a rather time-consuming and cost-effective process that requires relevant technical knowledge and skills, as well as a large number of different supplies and spare parts.
The simplest and less expensive option in this case is the homemade mini excavator based on the trailer in the form of carrier frame with one wheel pair on which installed autonomous Engine internal combustion, hydraulic engine and directly excavator equipment.
Where to get drawings
The next step when creating a homemade mini excavator is the choice of a specific model scheme, which includes all the necessary elements and sizes of individual parts and mechanisms.
At the same time, it is possible to develop your own design if there are appropriate technical knowledge and skills for this, having calculated the required power of the engine, hydraulic pump and hydraulic cylinder forces, taking into account the nature of future work performed.
You can also take advantage of the ready-made scheme developed by other craftsmen.
Ready drawings different models Mini excavators and instructions for their manufacture can be found on a variety of Russian and foreign sites on the Internet by entering the browser search box "Homemade Mini Excavator Drawing".
However, the circumstance should be taken into account that at most drawings presented on foreign sites, dimensions are indicated in inches. Therefore, for the convenience of further work it is necessary to translate them into a metric measurement system.
Having on his hands a specific scheme (drawing) needs to make an approximate estimate for the purchase required spare parts and materials as well as availability required tool, equipment and skills to handle it. Thus, it is possible to finally determine their capabilities and the prospects for independent production of a mini excavator.
Design features
The homemade mini excavator, as a rule, has a classic layout and a working cycle scheme on the principle of "reverse shovel", as in most industrial models of similar special equipment.
The main elements of such a scheme include:
- carrier frame on a wheeled or caterpillar;
- engine, driven by hydraulic pump;
- the reverse rotary platform on which the work equipment is mounted;
- hydraulic system, including hydraulic pump, oil filter, hydraulico, distributor with control handles, working hydraulic cylinders and connecting pipelines (hoses);
- work equipment in the form of a two-section rotary boom with a bucket.
As a carrier element, you can take the framework of the frame from the old tractor or trailer or make it yourself by installing the engine on it, fuel tank And at least one wheel axis, for example from the car. For greater stability and preventing possible tipping during work on the sides of the carrier frame, it is desirable to provide for the installation of two or four support shoes.
In such homemakes, the most commonly used japanese engines with a capacity from 6.5 to 15 kW, characterized by its compactness and reliability in operation.
Recently, their Chinese counterparts are also popular, which are actually not inferior to them in reliability and have a much lower cost (for example, the Lifan brand motors). More easily for this, various engines of domestic production are used.
Selection of individual nodes Mini excavator
Most simple option Assembly of the homemade mini excavator is the acquisition of an already finished arrow with a hydraulic system, which today are offered by some manufacturers and install it on a mini technique or homemade frame with engine and hydraulic engine. This avoids many problems with the setting of this equipment and the purchase of consumables and spare parts during its further operation.
However, the cost of such new equipment is high enough, so many homemade workers are trying to make it separate knots Alone, using hard materials or parts from the old special equipment with their refinement.
Hydraulic system
The classic circuit of the excavator hydraulic system includes 4 main sections, controlling the operation of the rotary platform, the lifting boom, handle and bucket. To simplify the assembly of the homemade mini excavator from the device of the rotary platform, it is possible to refuse, restricting the installation of the boom on the support-rotary column directly fixed on the carrier frame.
For a homemade version, you will need 4 hydraulic cylinder, providing turning and climbing / lowering the boom, the workforce of the handle and the control of the bucket.
For this, hydraulic cylinders with suitable parameters from various types of special equipment can be approached, for example used to lift the cabin of heavy vehicles (MAZ, KAMAZ, etc.).
Hydraulite
The choice of hydraulic pump completely depends on the preferences and financial capabilities of the wizard. The gear pump is characterized by simplicity of construction, unpretentious in operation and a small value. In contrast, an axial-piston pump is more expensive, but has more high power With the same overall sizes.
As practice shows, in homemade mini technique, the gear pump NSh-10 is most common with the R-16A distributor. To increase the required power, it is possible to use two such pumps and distributors simultaneously, which is often practiced by domestic manufacturers of special equipment.
Gears
Work equipment
As mentioned above, it is easiest to buy ready-made excavator equipment with an installed hydraulic system.
If this does not allow you to make existing finances, then it is cheaper to make a lifting boom and handle by welding from profiled pipes and sheet metal blanks of the necessary thickness, out-of-existing drawings.
Also, if there is such an opportunity, you can remove the arrow from the old frontal loaderBut at the same time it will have to thoroughly finalize.
In the photo Ready to install Working equipment
A mini excavator bucket is its main working body that perceives the main load during the sample of the soil. Therefore, for its manufacture, high-quality sheet steel is needed with a thickness of at least 6-8 mm.
The blanks cut off according to drawings thoroughly copier across all the seams. To enhance the design, the bottom and the upper edge throughout the perimeter are additionally amplified by steel plates.
The "fangs" of particularly solid alloys, for example, fingers from tracked tractors are additionally welded to the outer front edge of the bucket.
It must be borne in mind that for the assembly of the self-made mini excavator, certain parts and materials will be needed, as well as the need for various types of plumbing, welding, turning and milling and other types of work.
Before making a decision about his independent manufactureIt is necessary to assess the availability of the necessary parts and materials, its technical knowledge, skills and skills and the presence of the necessary tool.
Otherwise, it may turn out that the independent production of a mini excavator will cost more than the purchase of an industrially produced model, which has significantly better technical characteristics and more convenient in operation.

We collect mini excavator with your own hands
Compact construction equipment is very popular. Small dimensions, economical fuel consumption, and at the same time the functionality of a full-fledged model is preserved. No exceptions and excavators. Small-sized landing equipment is optimally suitable for small construction companies, utilities and individuals.
Due to the wide range of hinged units, the mini-excavator is able to perform a large list of works. But there is one problem: such models are from 300,000 rubles, so not every person can afford such a purchase. What to do in this case? Output one: construct a mini-excavator with your own hands.
Preparatory stage of work
First you need to decide which excavator you need. Self-sized earthmoving equipment is two types: self-propelled or trailed.
In the first case, you will need the engine so that the excavator can move independently. In the second case, the technique can be attached to the tractor or another tractor.
It is worth noting that the attached models are much easier to make with their own hands than self-propelled.
Any work on the creation of equipment begins with the drawings. This will help better calculate the traction effort, determined with the number of material, and think appearance Excavator. Drawings can be prepared independently, or take advantage of ready-made sketches on the Internet.
We select the necessary nodes
In order for the compact excavator to be practically no longer inferior to the car, they are made by their sample. Respectively self-made model Must have the following elements:
- Chassis. When creating a trailer option, a metal welded frame and one wheel pair will suit.
- Engine. Considering that the technique will work with a tractor, powerful force aggregate It does not make sense. You can do with a small engine, with a capacity of 6.4 kW. This is quite enough to start the hydraulic pump.
- Platform. Here will be the main components and mechanisms, steering and operator chair.
- Hydraulic system. This includes: pump, filter, connecting hoses and hydraulic distributors.
- Arrow with a bucket. This work element can be bought in the finished form.
Getting to work
Some homemade craftsmen collect homemade mini excavator from finished knots. The necessary details are purchased in stores, but in this case, it will be much easier and cheaper to buy a ready-made model. Therefore, we consider the option self-assembly From old details.
The wheel axis from the old automotive trailer. Metal sheets are welded on top to the chapeller, it will be a platform for equipment.
Arrow with a bucket. If you do not have experience in assembling complex mechanisms, it is better to buy a finished boom. With independent boom manufacturing, it is recommended to use round pipes or square cross section, with a wall thickness of 6-8 millimeters. The arrow consists of three parts that are connected by hinges or sleeves.
The bucket can be welded independently, from metal sheets. In order for the design to be strong enough, it is recommended to strengthen the upper part of the additional metal strip, put the longitudinal ribbies and make the "fangs". For the manufacture of teeth bucket, you can use metal "fingers" borrowed from the caterpillars of the old tractor.
Hydraulics. This is the most complex element of the mini excavator. The hydraulic system is responsible for the work of the arrows. To the arrow went down, turned and moved, you will need 3 hydraulic cylinders. Another one will be responsible for managing the bucket. You can remove them from any old truckwhere cylinders are responsible for raising the cabin.
It is almost impossible to make a hydraulic cylinder on their own, so do not waste time, but go by car autobacies and garages. There you will probably find the item you need.
To hydraulic system Worked, you need to install the pump. Optimally suitable for the NSh-10 gear type pump. Included with the pump you can use the four-section hydrodistributor R-16A or RGS-253. Everything hydraulic equipment It connects with the hoses. The pump connects to the engine, the oil container is installed on the platform.
Latest strokes
As you can see, you can make a mini-excavator, it is enough to make a little effort. In principle, after the assembly stages given above, the self-made technique is ready to operate.
To work with comfort, you can make a canopy or a small cab of a metal profile. Inside set the seat from the passenger car.
If you plan to work in dark time After a day, it makes sense to think about lighting.
Before you begin to assemble, think, maybe it will be better to purchase a ready mini-excavator? Homemade options are not much cheaper, and require certain skills when assembling.

IN householdEspecially in winter this idea of \u200b\u200bthe alteration of the motoblock under the bulldozer is useful. Snow in the yard will cease to be a problem for you, and its cleaning will turn into an interesting occupation. The peculiarity of this model is that this device is coping not only with snow, performing the tasks that it was built, but can cope with the works with the soil. It is proposed to make such a bulldozer on the example of the Skiper SK-800 Motoblock.
To eliminate the slip on the wheels, special weights are mounted every 35 kg weighing. Now we will install our refinement. Drilled hole and bushing inserted. The sleeve was chilled in a circle to fix. She does not create any interference to work there, but there is a lot of benefit from it.
Warded nuts with thread from two sides. The blade housing itself is made of barrel, that is, from the most remedies. Holes for setting an angle of attack.
Please note that the bulldozer made from the motoblock is simply and the first time. Now spend the test. How reliably shown on the video, the motor-block with its task copes easily. And although the dump was designed to clean the snow, it is completely under the power of the tractor and bulldozer function. Note - the motoblock works on idling. As we see in the skillful hands, the motoblock turns the bulldozer and can also be used as an alternative to the tractor.
Recall that this device was done with your own hands and is intended for cleaning from snow. As practice has shown, the fiberboard on wide wheels and with weighting agents does not raise at all. This simple device is fastened to several bolts. There will be a separate video about weighting.
discussion
max Kacchalkin
And the gearbox will not break from the fact that the weight is on the wheels? This is probably the same if you hang 10 kg to our feet and walk, and we will not pass 200 meters, but if weighing the body on the body then all the rules. What do you think about this?
Kupimtut. By Video.
+ Max Kacrykin is absolutely absolutely not the same. The load here is almost only on the tire of the wheel. And for her, 30 kg does not mean anything. An additional load occurs for the gearbox only at the speeds of acceleration. (This is when touching from the spot. Well, so trust the smoothly and no load.). During movement, the effect of the flywheel is used, which provides additional smoothness of movement (both in cars and tractors).
Max Berestov
The competent weight distribution, much better than to break the motoblock itself, where the load on the body, gearbox, and first of all suffer the bearings.
jercaa
kupimtut. By video is easier until Pukhlyak, I finally went to the chains. But there are sometimes collapse. I would advise you to make a plane on back sidewill easier move drifts.
kupimtut. By Video.
Honestly, I also think so. These motoblocks are not enough reduced transmission. I once remember rushed on the caterpillar DT-75, so there is a separate reduced gearbox, except for the main one.
Bogdan Mezenun
Very easy and accessible. I have a Tarpan, but he is without rear transmission and also dream to remake it on winter under the cleaning of snow. Question? And where did you get the wheels and how to customize the mount?
Kupimtut. By Video.
The wheels were developed precisely for this model at the production of Skiper. True, when buying, they were not in warehouse and had to wait when they appear and buy. There was a moment when this model was bought precisely because of the wheels. Theoretically, judging by other reviews, you can say anything and think. But in reality, as I saw - snow, sand, the soil passes confidently under load. It's a pity now left the owner of this unit, would post the video in the snow. The theory and speculation is one, and practice and reality is quite another.
Kupimtut. By Video.
Kupimtut channel response: Duck is made by the Belarusian craftsman for himself personally and is intended solely for snow cleaning. With this task, he copes completely. Cleaning the courtyards and adjacent to the house territories by 100% without effort and problems.
Fair for the sake of quoting the readable part of the remote:
"For those who are in the subject it is clear that it is crap. Dumping for sand and land has the wrong angle of attack, it dopped under the snow, but it can row the snow only in a straight line or under the slide. The slightest rise and everything ass. I have a fiberboard with a dump and counterweight weigh 270 kg and then on the lift is very hard to work on the primer "
channel response KupimTut: The adapter is not intended for sand and land. The video demonstrates in connection with the lack of snow and for visual assessment of the power of the motor-block Skiper. The user is sold as unnecessary by the user.
Kupimtut. By Video.
+ Boris Yurchenko Yes, just lucky - there was such a diver. Bolt is attached from the inside (a carving is cut in a blank. The same bolts, as the wheels. I know a person who can do.
The people were used to calling the tractor blade the shovel. But not about the names will be talking, but about independent manufacture For tractor.
Not everywhere nearby are shopping centers, dealers and other salons, where it is easy to buy for the tractor dump. So for a person having a tractor and living in the village, it is easier to make it easier to dope with your own hands than to buy in the city.
Dump is hollow construction, boil dumps from thick sheets become. At the front of the front, knives are attached to bolts. If necessary, they can be removed.
From the back, in the center, the bracket is located with which it dropped down and rises.
There, only on the sides, solders are weldedwhose hinge connections are attached to. The only thing - the tractor must have Hydraulic system.
Views
Dumps have different geometric configuration - Depending on the type of work, which performs a tractor with a dump.
When the task is to move a lot of bulk materials, and quickly, bulldozers are used with dumps spherical or hemispherical.
On the sides of the dump make special openings - In order for the bulldozer to capture the material for example, sand, soil, like in the bucket.
If you need to fall asleep a trench or a pit, it will take off, capable of turning 25 degrees to the side of the sides.
With the opening or removal of the upper layer of the soil, the bulldozers will be required, equipped with Responsible dumps. This "shovel" has a wide capture.
Direct dumps can be rightfully called universal.
The tractor equipment must allow the dust overwhelming - this will allow you to work with both normal and sturdy soils. Such better cuts surface.
If the tractor is small, for example, the T-25, to make it dump in principle is easy.
For this, it is necessary, firstly, steel pipe A diameter is not more than 50 cm. Pipe cut into 3 segments along. One will become a frontal plane - front dump, another rear - rear, and make the third discoveries and perimeter box.
To the finished shovel brew stubborn pushersthat should be fixed on the carrier part of the tractor design. Use for fastening floating hinges.
From the back, in the center, breed two strips of thick iron. On the plates should be calibrated holesbecause they will be attached to them rod hydraulic cylinder.
So, now you know, what are the bulldozer dumps, and for which each design is suitable.
Example How to make front Ducklings from barrel
Recently, I managed to visit the "Promractor" plant in a good company, which is located in Cheboksary. Enterprise enters the concern " Tractor plants"And deals with the release of a wide line of tractors, bulldozers, pipestovers, excavators and other heavy equipment under the brand" Chetra ".
Today, specially for readers of the community report on how techniques make for various needs and the biggest bulldozers in our country.
During the Soviet Union, the plant produced only one model - a heavy industrial tractor T-330. Now there are graders, bulldozers, excavators, all-terrain vehicles, loaders, pipelords, loaders, timber industrial equipment, and even rollers, more than 10 models of technology are produced.
The plant has recently been upgraded, equipped with new machines to be competitive not only in our market, but also abroad.
New machines allow you to make more diverse details than it was possible on old Soviet counterparts.
Details at bulldozers are not small.
However, there are quite a few older machines at the plant, both Soviet who make only a few operations and German, such as Schiss processing complexes that were purchased in the mid-80s. The line is still working and consists of 25 processing centers that differ only with snap and software. It was pretty here muddy glassbecause this photo is.
Large factory workshops are not loaded on full powerBut here and there are ready for the assembly of part.
The lines in one of the workshops are serviced here such small automatic loaders who are moving themselves along a specific trajectory, which is set by special marks mounted in the floor. In the photo they are also visible.
We found the plant during the renovation, because the workers were little, although, as we were explained, there are only 20 people in the workshop of machining. This is enough, because all the work are performed with CNC machines, the workers remain just follow the process.
In the Soviet times, the number of workers on the industractor reached 30,000 people. The plant then produced about 2000 T-330 tractors per year. Now the plant produces about 1,200 units of various techniques, and the staff is only 3,000 people.
Next door to modern automated centers are completely old machines. This is a neighboring workshop - transmissions shop.
On the floor - the metal tile of Soviet times, it is unlikely that time will be able to spoil it.
The capacity of the enterprise has not changed, although in the number it became less, but the line of the manufactured technique has significantly expanded. Previously, the model of one tractor was easier than now dozens of different models of machines, many of which are much harder and more difficult than the T-330.
Reducing the number of employees occurred not only thanks to automation. Previously, the "InterMractor" represented a typical plant "all in one" plant for the USSR. Here they produced all, ranging from nuts and bolts. But it is very inefficient, and now production is completely small details Located on the outsource. The foundry produced by another plant as part of a single concern is also derived.
Old equipment is gradually exported from the workshops, and goes on scrap metal. The liberated areas are engaged in other needs, like this shop for assembling transmissions for agricultural dammes.
On the walls of the plant posters with a picture of products manufactured.
Simple Cheboksary Workers.
Here is such a cool stall with pleasant girls standing right in the workshop! True, he did not function, we did not try corporate factory pies).
Soviet slogans are given almost all the factories created in Soviet times. True, not all of them survived, in contrast to this.
In addition to robot loaders, there are other copies controlled by people. You can say rarities.
Go to the assembly shop.
Details and machinery themselves seem giant.
Here, as you see no conveyor. Each bulldozer is collected in one place.
If some workers hid from the cameras, then others, on the contrary, asked to photograph them.
In the last stage, as I understood the caterpillars.
Cosmonaut, worker and worker of cultivable events?
On these tractors, we will soon have a test drive.
Cabins and other external details are painted in a modern painting chamber by powder spraying.
This looks like an inside of the Cabin Tractor "Chetra". There is no steering!
Hello Vitaly dervishV. .
And these cabins will be installed on the tractor of the Vladimir Tractor Plant
The assembled car is sent to the test, and after their passage is sent to the customer into one of 40 countries of the world. Chetra technique is widely demanded in Australia, Egypt, Indonesia, Mozambique, Syria, South Korea. For testing at the factory there is a private landfill.
Loaders.
And now we are waiting for a small show, on which we will demonstrate the possibilities of the "Chetra" technique.
Probably paid attention to the branded colors "Cheters"?
Here the cochant of the new C-33 career dump truck was also presented with a carrying capacity of 33 tons. Now he is tested. Those who have seen Volvo dump trucks can find comparisons between them.
Soon and he will go into production. In general, if earlier the plant was produced only by industrial tractors, now the excavators also do here and soon the production of dump trucks, and even combine harvesters will begin. Here on the "InterTractor" translated production of combines "Yenisei" from Krasnoyarsk.
This is done because the main consumers of this technique are in the European part of Russia, as well as the main suppliers of components, some of which are produced here, on the interface.
Here every year they introduce 1-2 new models, and about 20 new units of various techniques are being prepared in different degrees of readiness.
Tractors like this are used on the laying of pipes.
Excavators "Chetra" are not inferior to foreign counterparts. And at a price even more accessible.
The Abbreviation T-6 means the tractor weighing 6 tons.
T-11 respectively -?
By the way, the chetra technique was used in the construction of the largest infrastructure projects of modernity, such as Eastern Siberia Pipelines - Pacific Ocean, Sakhalin-2, Blue Stream gas pipelines, Vankor Purpe, "Main-Gryazovets".
Well here and the show starts! The bulldozer shows how the bucket can rotate.
Enters the podium.
Egg and match boxes are not accidental here.
Caller with paint too.
But first, the bulldozer is raised on the bucket and the teeth of the car located behind and rotates the caterpillars.
And now the test is accuracy. Despite the huge weight of the car and the seeming clumsiness, the operation on the closing of the matchbox and the neat sugar shell is successful).
These cars even participated in the transfer of "Minute of Glory", where they showed their extraordinary opportunities. In particular, one of the tractors "Chetra" drove along the improvised bridge from two ropes, it impressed me.
After the show, a solemn event took place. The "Cheters" has a tradition to call the technique by the names of the glorified athletes. This time, two loaders were honored so honored: they were given the names of the Universiade 2013 championships, Olga Tooth and Tatiana Kashirina
Moment of glory).
And now on the landfill. The photo shows the largest domestic bulldozer T-40. Soon I will sit in the driver's place to blast them and roll the photographer in the nearest me).
Inside the bulldozers are girls working in enterprises. Like a hint that even a girl can cope with the technique)
I am removed the camera. Waiting when I finally fall under the caterpillars)

The world of special equipment amazes with their diversity. However, we observe with a special tender for homemade technique. Your attention is presented photos of technicians made by your own hands.
And if the minite equipment is made with their own hands for a personal compound and with a soul, then the work argues twice as fast. In any case, I want it to be so. I built a mini-excavator - and softened the whole field, built a dumper - the soil transported. But this, as is known, depends on the hands, his craftsmen. Let's see what masterpieces homemade technology For personal compounds are able to make folk craftsmen!
So, the first photo of homemade technology. We talked about thought ... Forget! Here she apparently left the wizard. To work on such a homemade mini-bulldozer, apparently, it is necessary to jump into it from the run. And to register so to fit into the window. And if you are more than one meter tall, you are not destined to ride this masterpiece!

When winter comes, the owners begin to think about how to remove snow in a large area. Many people continue to think until spring, and some take and master the minite equipment for a personal foundation with their own hands. For example, here is such a homemade snowpressure.

Here the issue of snow cleaning is resolved much more prose. Snow must be accepted. The most important thing in this process is shouting: "Spring, come, snow raised!"
