The KS-35719-1 truck crane with a lifting capacity of 15 tons is mounted on a two-axle chassis of a KAMAZ-43253 vehicle and is designed for loading and unloading and construction work at dispersed facilities. Due to its small transport dimensions and excellent maneuverability, the crane is primarily intended for use in the natural conditions of modern cities, where it can move freely in dense traffic flows. According to these indicators, as well as in terms of cost, this crane is the best alternative to the widespread crane model on the MAZ-5337 chassis. The crane system is driven by an axial piston hydraulic pump, which is driven by the engine of the base vehicle through a gearbox and an additional power take-off. Crane mechanisms have an individual drive with independent control from hydraulic motors and hydraulic cylinders. The hydraulic system of the crane installation provides smooth control of all mechanisms with a wide range of regulation of all mechanisms with a wide range of speed control of working operations, provides the ability to simultaneously combine several crane operations. A two-section telescopic boom with a length of 8-14 m provides the crane with compactness and maneuverability when moving, a large working area and a large height of the load during operation. To increase the service area and the size of the boom space, the crane can be equipped with a lattice jib 7.5 m long. In the transport position, the jib is turned and fixed on the side of the boom. The jib is moved from the transport position to the operating position and back manually without the use of additional lifting equipment. The reliable operation of the truck crane is ensured by foreign-made components that do not require replacement and repair during the entire service life of the crane. Safe operation of the crane is ensured by a set of instruments and devices, including a microprocessor-based load limiter with digital indication of operating parameters on the display in the crane operator's cab. The device automatically protects the crane against overload and overturning, is equipped with a crane coordinate protection system necessary for working in confined conditions, has a built-in telemetry memory unit ("black box") and a crane protection module against dangerous voltage (MZON) for operation near lines power transmission. The truck crane is equipped with a crane operator's cabin that meets the latest requirements for comfort and visibility: a sliding compartment door, a diesel heater, a fan, a hinged rear hatch, a convenient dashboard. Ease of control of crane operations is achieved due to the original arrangement of the control levers.

Engine
The restyled KamAZ-43253 is equipped with a slightly less powerful engine than its predecessor KamAZ-4325 (engine KamAZ-740.31-240), but a much more modern and economical engine. This is a Chinese-made Cummins ISBe6.7 E5 250 in-line six-cylinder diesel engine. It has a displacement of 6.7 liters, is equipped with a turbocharger and an intercooling function for the charge air. The rated power of this turbodiesel is 185 horsepower, and the maximum net power is 178 horsepower (develops at 2500 rpm).
- The maximum torque is 937 Nm (96 kgf.m), already at 1300 rpm.
- The compression ratio is 17.3.
- Cylinder diameter - 107 mm; piston stroke - 124 mm.
- Maximum idle speed: 2850 rpm.
- Minimum idle speed: 600 - 800 rpm.
- Maximum operating altitude of the motor: 3000 m above sea level.
- Motor weight: 512 kg.
The engine is equipped with a Common Rail electronic injection system. Over the years of production, the Cummins ISBe6.7 E5 250 diesel engine has been consistently upgraded from Euro-3 to Euro-4, and then to Euro-5 standards.
The assembly of these power units is carried out in Naberezhnye Chelny, at the Cummins-Kama joint venture. The production program of this joint venture includes three families of engines. Inline “sixes” with a capacity of up to 300 hp, which include the KamAZ-43253 engine, make up about 80% of the production volume. They are used on various models of medium and heavy KamAZ trucks, as well as on NefAZ buses. The rest of the production volume - diesel "four" Cummins ISBe4.5, presented in the power range from 140 to 185 liters. with., as well as engines of the L8.9 series - with a working volume of 8.9 liters, with a capacity of up to 400 hp.
Starting with a simple screwdriver assembly of Chinese diesel engines, Cummins-Kama has gradually moved into a full-fledged production activity, having mastered all the technological processes of processing the cylinder block and localizing more than 50 percent of the components, including the cylinder block, cylinder head, crankshaft and flywheel.
Fuel consumption
In terms of operational measurements, they are highly controversial, and do not always converge with the fuel consumption that is obtained in practice. However, in general, KamAZ-43253 can be considered one of the most economical trucks among competitors. Its average fuel consumption is 25-30 liters. It all depends on the manner and nature of driving. Due to the fact that the car is very dynamic and nimble in management, many drivers allow themselves to take liberties, and thereby force the engine to constantly work at high speeds. In such conditions, fuel consumption will easily exceed 30 liters.
Transmission
The 5-speed manual gearbox KamAZ-142, which has a remote mechanical control and a final drive ratio of 4.98, has also gradually faded into the past, along with KamAZ-4325. A 6-speed ZF 6S700 manual transmission with a main gear ratio of 6.53 is installed on KamAZ-43253 vehicles.
It is a six-speed gearbox, in which all forward gears are engaged by synchronizers, and the reverse gear is a toothed clutch. Top gear - overdrive. The maximum torque is 700 Nm. The weight of the ZF 6S700 box is 103 kilograms. The checkpoint of this model has proven itself well on distribution trucks operating on intracity routes. Countless stops, maneuvers in tight spaces - these conditions require modern drive technology, such as the ZF 6S700.
Both of these transmission options - both the old and the new - work in conjunction with a single-plate diaphragm clutch of a push-type hydraulic drive, which is supplemented by a pneumatic booster. At present, KamAZ-43253 are equipped with a clutch of the "ZF & Sashs MF 362" model. The model in the domestic auto industry is quite common: apart from KamAZ, such a clutch basket has long been installed on the trucks of the Minsk Automobile Plant: MAZ-4370 "Zubrenok", MAZ-4570; buses PAZ / KAVZ.
The manufacturer of transmissions ZF Friedrichshafen AG is one of the leading supplier groups to the automotive industry. With this company, KamAZ also created a joint venture: "ZF-Kama" and set up an assembly production of manual transmissions in Naberezhnye Chelny.
Dimensions and load capacity
The length of the KamAZ-43253 chassis is 7425 mm, and the length of the onboard modification reaches 7505 mm. The volume of the wheelbase has not changed compared to its predecessor, and is still 4200 mm. In addition, both versions (past and modern) have a front overhang length of 1260 mm and a rear chassis overhang length of 1660 mm. The maximum truck height (from the ground to the top of the cab) reaches 2,785 mm. If a cargo superstructure is being erected, in this case the maximum height should not exceed 3320 mm. As for the cargo platform, it also has impressive parameters - its length and width are 5162 and 2470 mm, respectively. The height of the metal tailgate, which complements the platform, reaches 730 mm. In addition, the customer has the ability to retrofit the cargo platform with a frame awning. The height of the loading compartment for modification 43253 is 1380 mm, which is a decent indicator at the level of competitors from the budget class.
The KamAZ-43253 chassis is designed for a curb weight of 5660 kg, the maximum permissible weight of the updated truck reaches 15.5 tons. At the same time, the carrying capacity is within 9690 kg, which is 8% more than that of its predecessor. Now let's move on to the airborne version - its curb weight is 6620 kg, and the carrying capacity is 7820 kg. Also note the total weight of 14,590 kg. According to the manufacturer's recommendations, the design of the front axle of the car is designed for a useful (maximum) load of 5310 kg, and the rear axle for 9280 kg.
The upgraded version of KamAZ-43253 has a frame structure, using a spring suspension for the front and rear wheels. In 2017, such a scheme can already be considered outdated, but it has been tested by time and does not cause any particular problems. In addition, the springs are reliable and durable, and withstand excessive overloads perfectly. All wheels are equipped with drum brakes, the efficiency of which is doubled by pneumatic drive. The drum diameter is 400 mm and the brake pad width is 140 mm. The truck is equipped with a classic 4x2 wheel arrangement.
KamAZ-43253 has a high adaptability to Russian conditions - largely due to two powerful batteries. Their total capacity is under 400 mAh. In addition, a 28-volt 2000 W generator is included. In addition, the list of equipment includes fog lights, a plastic shelf in the upper part of the cab (has three compartments for large and small luggage), improved sun visors, a multifunction steering column (adjustable for departure), an air-suspended driver's seat and a new dashboard. By the way, the latter is covered with an anti-reflective coating. The diesel version has a fuel tank capacity of 350 liters.

General information
KamAZ-43253 is the optimal modification for those companies that need universal vehicles operating in different fields of activity. Moreover, this version looks more preferable in comparison with trucks of a higher class, with which KamAZ-43253 is ready to compete in terms of carrying capacity and survivability. At the same time, the Russian truck attracts with its low operating costs. Among them are relatively low fuel consumption and high power.

Design and salon
KamAZ-43253 has a brutal appearance, in the spirit of the KamAZ family cars, produced since the 1970s. The 43253 version itself is a chassis with a high-capacity onboard platform. Today, a version with an updated cab is being produced, in which the bumper and body are a single whole. At the same time, the radiator grill, made in a strict style, smoothly transitions to the bumper - such a design solution not only adds brutality, but also the cooling efficiency of all technical units and assemblies. We also pay attention to the massive wheel arches - this is also a design touch that makes the truck visually more aggressive and wide. In addition, such arches are better at preventing splashes - for example, in rainy weather.
The internal space of KamAZ-43253 is designed in a classic style, like trucks of previous generations. Despite the large-scale modernization of the design, the car's interior looks as brutal as the design. Controls and switches still evoke associations with KamAZ vehicles of the 1980s. But despite the outdated design, it is worth noting the excellent ergonomics and thoughtfulness to the smallest detail. The front panel is simple and unpretentious. Moreover, I must say that in terms of ergonomics, KamAZ can be considered one of the best in this class, even among foreign cars. In terms of build quality and materials, all of this, of course, leaves much to be desired. Squeaks and vibrations in the passenger compartment appear after the first thousand kilometers of operation. And yet, most owners are happy with the car.
The KamAZ-43253 cab is an all-metal folding, has a high roof, and is also installed on air suspension. The developers have improved the soundproofing of the cabin, but there have been no significant changes in terms of acoustic comfort. Let us repeat that KamAZ-43253 is focused on transportation within cities, like its predecessor. That is why the car does not have a full berth.

Engine and fuel consumption
KamAZ-43253 is equipped with a Cummins 4 ISBe 185 diesel engine. The main advantages of this engine are increased service life, as well as better fuel efficiency compared to the power plant of its predecessor. The working volume of the new internal combustion engine is 4.5 liters. The unit is equipped with turbocharging technology, due to which the power reaches in the range of 179-185 horsepower. In this case, peak power is already achieved at 2500 rpm. In addition to turbocharging, the engine provides for intercooling of the air emitted by the turbine. According to official figures, the maximum torque of the diesel engine at 1700 rpm is 636 N / m.
The power plant is aggregated with a mechanical five-speed gearbox of its own production KAMAZ. A feature of this gearbox is the presence of a remote mechanical control, and the main gear has a gear ratio of 4.98. This indicator allows you to quickly change gears, and thereby keep the engine running at high speeds. Thanks to this, KamAZ-43253 has decent dynamics even in urban conditions. We can say that the fast gearbox allows the 4.5-liter diesel to be fully realized.
A more expensive version of KamAZ-43253 is offered with an imported mechanical 6-speed gearbox from ZF. This transmission has a main gear ratio of 6.53. Despite the significant difference in design and settings, both boxes have the same single-plate diaphragm clutch. The best clutch performance and endurance is achieved with a hydraulic drive and pneumatic booster.
KamAZ-43253 with both gearbox options accelerates to 90 km / h on a hard surface. Moreover, in this case, the car can be fully loaded. This means that without a loading platform, the maximum speed can be much higher.
Fuel consumption
In terms of operational measurements, they are highly controversial, and do not always converge with the fuel consumption that is obtained in practice. However, in general, KamAZ-43253 can be considered one of the most economical trucks among competitors. Its average fuel consumption is 25-30 liters.

Due to the fact that the car is very dynamic and nimble in management, many drivers allow themselves to take liberties, and thereby force the engine to constantly work at high speeds. In such conditions, fuel consumption will easily exceed 30 liters.
Prices in Russia
KamAZ-43253 can be considered the most affordable medium-duty truck on the Russian market. The minimum cost of the model is 1 million 300 thousand rubles. True, for this money, the buyer can only find the usual version with a single chassis, while the version with a full-fledged cargo platform will cost 700 thousand rubles or more. It all depends on the driving style.

Medium-duty vehicles of the KamAZ-43253 family are high-quality trucks for the transportation of all kinds of goods within the city and for the production of various special-purpose vehicles.
Production of Russian trucks
The domestic enterprise KamAZ for the production of heavy-duty vehicles was founded in 1969, and in the same year the construction of the company's production facilities began. At the same time, the city of Naberezhnye Chelny was being built.
The first KamAZ truck was manufactured at the beginning of 1976. It was an airborne model under the factory index 5320 (currently in the museum of the enterprise). By 1980, the company produced more than 150 thousand heavy vehicles and continued to grow production. In the mid-eighties, almost a quarter of the fleet of automobile cargo enterprises consisted of KamAZ trucks. Therefore, the creation of a corporate service center in 1983 made it possible to increase the efficiency of vehicle operation.
A feature of the first ones produced was the presence of three bridges. With the decrease in the production of cars at the ZIL enterprise, the need for trucks with two axles has increased. In 2003 the company started production of a new model range of trucks, which includes KamAZ-43253 with technical characteristics typical of a two-axle vehicle.
Release of trucks with two axles
The production of medium-duty trucks of the 4325 series at the plant began in 2006. According to its technical characteristics, the KamAZ-43253 modification is most suitable for operation in urban conditions. This advantage is provided to the truck by the presence of two bridges and, as a result, improved maneuverability and controllability in heavy traffic and dense urban infrastructure.
The vehicle has several modifications, the most common among them are tractors and on-board options. In addition, the technical characteristics of the KamAZ-43253 chassis make it possible to create a large number of special vehicles on its basis, which include:
- garbage trucks;
- various tanks;
- fire versions;
- aerial platform;
- manipulators;
- road and utility options;
- lifting cranes;

Both of these transmission options - both the old and the new - work in conjunction with a single-plate diaphragm clutch of a push-type hydraulic drive, which is supplemented by a pneumatic booster. At present, KamAZ-43253 are equipped with a clutch of the "ZF & Sashs MF 362" model. The model in the domestic auto industry is quite common: apart from KamAZ, such a clutch basket has long been installed on trucks of the Minsk Automobile Plant:, MAZ-4570; buses PAZ / KAVZ.
The manufacturer of transmissions ZF Friedrichshafen AG is one of the leading supplier groups to the automotive industry. With this company, KamAZ also created a joint venture: "ZF-Kama" and set up an assembly production of manual transmissions in Naberezhnye Chelny.
Cab KAMAZ-43253
Trucks of this model are equipped with standard KamAZ (licensed Mercedes) cabins without a berth; both with low and high roofs. These are comfortable (especially compared to the classic KamAZ) cabins with four-point air suspension, from the Mercedes-Benz Axor truck.
Since the beginning of 2010, all new Kama trucks have been equipped with it. The air suspension mount significantly improves ride comfort, reduces vibrations and prevents cab rocking when driving at speed. And also, for ease of driving, it maintains a constant level of the cabin height, regardless of the vehicle load.
The combination of this new air suspension of the cab and a comfortable seat (also with vibration-damping air suspension, with lateral support) made it possible to raise the level of comfort to a level never seen before for KamAZ. The driver's and passenger's seats are equipped with 4 levels of position adjustment.
The steering column of the car is also adjustable. Pneumatic steering column control allows you to easily adjust the position of the steering wheel in height and tilt. The steering wheel itself is equipped with a hydraulic booster.
The quality of the materials for the interior trim has improved markedly. The plastic of the panels and dashboard has become softer and more pleasant to the touch. The dashboard has been redesigned in accordance with modern trends, equipped with an anti-reflective coating. A well-placed graphic display, pointer indicators and control indicators allow the driver to instantly receive the necessary information without being distracted from the road.
The door handles are made of plastic, with built-in locks, protected by air flow deflectors. This keeps the door handles clean, along with the fairings on the sides of the cab. These fairings reduce air turbulence and reduce contamination of the stream, mirrors and doors in general.
Instead of the old metal "bump stop", a cast plastic bumper painted in the color of the cab is installed on the restyled cab. The footrests are fitted with anti-slip pads on both sides. Getting into the cab is safe and comfortable in any weather. The restyled cab also features fundamentally new optics, with improved visibility and visibility. The headlight, side lights and turn signals have merged into a single unit.
The shape of the bracket has been changed for the rear-view mirrors. Roll-up and curb mirrors are on the right, and spherical mirrors have been added on both sides to cover blind spots. The windshield is one-piece, with three wipers.
