Truck crane KRAZ-250: technical characteristics of the large crane KS 4562

KrAZ-250 is a truck that belongs to the heavy class. The vehicle was produced from 1978 to 1992. Its production was carried out by the Kremenchug Automobile Enterprise. The vehicle body is represented by a platform with opening rear and side sides.

As a standard, various equipment was mounted on the platform, along with bodies, and on-board models are quite rare. In addition, they produced a truck tractor, which was based on the KrAZ-250 platform.

Very often I came across, and even now, a car with a modification of a lift, truck crane and concrete mixer. Today the plant no longer produces this model. The entire KrAZ model range.

Car history

The truck dates back to the 1950s. From the start of development to the start of serial production, no less than 20 years passed. The need for technically advanced, comfortable types of heavy special equipment has matured since the late 1950s, but full-scale production of the modeled truck was hampered by dependence on adjacent suppliers of the required components.

Only after a couple of decades, KrAZ vehicles of the brand new 250 series were able to come out. The transport model in question, which was produced at the Kremenchug enterprise from 1978 to 1992, was conceived and created as a unified vehicle, the chassis of which can be used to mount various types of special equipment on it.

The KRAZ-250 truck can be classified as one of those types of special equipment that are used and developed today. It is clear that the car is already outdated, but the new units copy its options, albeit in a more modernized variation.

Thus, a machine with a standard frame mounted on it can offer use with an onboard platform, which, by the way, can be found in this version quite rarely. The car was equipped with a chassis with a shortened frame variation, which was used to install truck cranes, concrete mixers and other installations on it.

Special equipment based on the 250th KrAZ was able to find the widest use in mining and oil-producing areas, and is also often used during construction and for military purposes. Therefore, the engineering and technological staff was able to complete the task of designing the original car.

Important components are interchangeable, both in the various series of the enterprise in Kremenchug, and with types of machines from other companies, for example, MAZ-500A. As a result, 1978 allowed the company to release the KrAZ 250 chassis, which can be a platform for many variations of modifications.

The 6x4 model was produced until 1992, and during this time the cabin was modified 3 times. In 1992, an automobile company in Kremenchug introduced dump truck versions of the KrAZ-6510 and KrAZ-6443, which became the next family of our vehicles. The KrAZ-250 itself became a modernized version of the KrAZ-257.

Truck Features:

1. The KrAZ-250 truck crane stands out among its analogues due to its excellent performance indicators and the best speed development parameters. It is very comfortable for the driver to be in this car, therefore his fatigue is reduced and his ability to work at the workplace increases.
2. The updated version of the truck also highlights all the characteristic advantages of KrAZ equipment. This is ease of use, both when driving and when carrying out minor repairs. The machine is distinguished by its endurance, high performance and reliable design. A KS-4562 truck crane is mounted on the chassis.
3. The car can be used not only for driving on a hard paved road on a highway, but also on roads paved with dirt. is permitted over a wide temperature range from -40° C to +40° C (as well as Ivanovets 25 tons). Thanks to this discrepancy in temperature indicators, it became possible to operate the KrAZ-250 in different climatic zones.

The KrAZ-250 belongs to those types of special equipment that are used and developed today. Now this is an outdated model, but new units repeat its functions, albeit in a more improved version.

The most common and popular trucks are often modeled after the design of the KrAZ-250 or similar devices. This equipment includes many additional functions and is characterized by high reliability.

Features of KrAZ trucks

The KrAZ-250 is a modification of the KrAZ-257B1A truck, the production of which never ceased even after the launch of the restyled model. The differences affected not only the exterior (refreshed both inside and outside the cabin, shorter hood), but also in almost all standards, such as fuel consumption and increased mileage to 1 maintenance.

Our guest, unlike the previous model, has improved efficiency, acceptable speed performance and a sufficient level of comfort for the driver. But among the traditional qualities of cars produced by the enterprise in Kremenchug are ease of use, endurance and reliability, which is exactly what the 250th brand has.

The KrAZ-250 can operate not only on roadways where there is a hard surface, but also where there are even dirt roads. Moreover, the car can be operated in different temperature conditions, from -40 to +40 degrees Celsius. This has made it an indispensable model that helps in geographical areas where different climatic conditions are present.

Steering and brake control

The steering mechanism is made according to the principle of “screw and ball nut-rack”, which meshes with the gear sector. The hydraulic booster acts on the longitudinal steering rod. It consists of a power cylinder and a distributor. The steering gear ratio is 23.6. Oil pressure in the hydraulic booster is up to 70 kgf/cm. sq.

The working brake system is a 2-circuit pneumatic drive and drum mechanisms on all wheels. The first circuit guarantees the operation of the brakes on the front and intermediate axles, and the second circuit is intended for the rear axle. Increased reliability is ensured by transmission parking and spare brakes. There is an alcohol-type fuse and a moisture separator that prevent condensate from freezing.

In the front drum mechanisms, the diameter is 42О mm, the width of the linings is 1ОО mm; in the rear - diameter 44О mm, width of linings 14О mm. Cam release. The auxiliary brake is a motor retarder with a pneumatic drive.

Cabin interior

The Kremenchug Automobile Plant envisaged the installation of a metal cabin, which is designed for a driver and a couple of passengers. The driver's seat can be adjusted to suit your own height and weight.

Among the comfort features, one can highlight the presence of a heating system, blowing windows with a stream of warm air, a cleaning mechanism for windshields, rear-view mirrors, a fan, lowering windows, and rotating windows.

There is also a radio, a document compartment and a sun visor. The dashboard has indicators that inform the driver about switching high beams, changes in pressure in the pneumatic system receivers, the oil level in the power unit and overheating of the cooling fluid.

The cab and tail of the truck are attached to the chassis in four places, which allows such elements to be separated into a separate structural unit.

What kind of oil should I put in the gearbox?

The KrAZ-250 requires an oil change depending on the season . There are options for all-season use:

• MT-16P.
• TAP-15V.
• USsA.
• CIATIM-201.
• CIATIM-221.
• Fatty solid oil.
• Grease 158.

In winter, there is often a need for more advanced products:

• MS-G4.
• TC-10-0III.
• Spindle oil AU.

There are options designed specifically for use in summer:

• MS-20.
• Industrial oil 20 (spindle 3).

Specifications

Power unit

The cargo vehicle was powered by a V-shaped eight-cylinder 14.86-liter diesel engine of the YaMZ-238M2 model. It allowed the development of 240 horsepower and ran on diesel fuel.

This engine had an all-mode frequency regulator, a low-pressure pump, which had the option of pumping fuel, and a fuel injection advance clutch. On top of that, the power unit had a preheater and a dry air filter, where there was an indication of clogging.

Engine YaMZ-238M2 Among the innovations, one can note the presence of an improved tubular-band radiator cooling, which replaced the previous tubular-plate radiator. The high-pressure fuel pump (HFP) is an eight-section spool type, which has a low-pressure fuel priming pump.

The nozzles are closed type. The engine allows such a heavy car to accelerate to 80 km/h and overcome an incline of 35 degrees. The average engine appetite is about 35 liters per 100 kilometers.

The car comes with a pair of fuel tanks, each with a capacity of 165 liters. The KrAZ truck crane works perfectly with such an engine, and there is no lack of power.

Transmission

The design of the KrAZ-250 truck provides for the installation of a dry double-disc clutch YaMZ-238, which has peripheral springs and a mechanical release drive, as well as a three-way five-speed manual gearbox YaMZ-2 36N. It has synchronizers at second, third, fourth and fifth speeds.

There is also a transfer case, where there are a couple of operating stages, as well as a center differential with the ability to block. All this significantly increases the speed capabilities of the truck. The transfer case is switched mechanically, the differential locks are activated pneumatically. There are 3 cardan speeds.

Suspension

The suspension installed in front received semi-elliptical springs, which are equipped with shock absorbers. And the rear suspension has two semi-elliptical springs, complemented by reaction bars.

The rear axle has a balancing type, where there are sliding ends of the springs. The front axle was unified with the MAZ-500A axle. The ride height is a respectable 275 millimeters.

Brake system

The main braking system is a double-circuit pneumatic drive together with drum mechanisms. The system operates on all wheels. The first circuit provides brake operation to the intermediate and front axles, and the second circuit to the rear axle. Confident reliability is guaranteed by a parking brake and a spare brake, which also enhance the technical component of the truck.

The parking brake is represented by a transmission brake, which has a mechanical drive. It acts on the rear axle. The described system has an alcohol-type fuse, together with a moisture separator, which prevents condensate from freezing.

It knows how to optimize the operation of a functional unit, which allows you not to worry about its reliability even in severe frosts. The car has discless wheels, which are similar to those used on MAZ cars. All wheels are equipped with only drum brakes.

Steering

It is represented by a screw with a ball rack, as well as a hydraulic power steering wheel, which greatly facilitates turning. The minimum turning radius of the machine is 13 meters.

Device. Similarities and differences between KrAZ-219 (-257) and KrAZ-250

In addition to a completely new cabin, the other main innovation of the KrAZ-250 was the 8-cylinder diesel engines of the YaMZ-238 family. Structurally, the KrAZ-250 was created on the basis and many components of the KrAZ-219/257. But it was made with updated units and using more modern technologies at that time. In particular, the axles and suspension were “inherited” from the 257th family. But the spar frame of the KrAZ-250 truck is made of thicker steel, 8 mm, with cross members and reinforcing elements. The frame features bolted connections that increase flexibility and strength under a variety of load combinations. Frame width – 860 mm.

The engine, as already indicated, was new. Several quite important changes were made to the truck's transmission. For example, the driveshaft began to pass through the middle bogie and be connected from the cab, from the transmission control panel. Such a solution contributed to the release of 350 kilograms of payload and made it possible to expand the capacity of the fuel system. On the KrAZ-250 it became possible to place two tanks with a capacity of 250 liters of diesel fuel and another one with a capacity of 50 liters of diesel fuel. This provides a power reserve of almost a thousand kilometers.

The cardan drive consists of two shafts with a sequential drive. Cardan shafts are tubular, open type. The diameter of the front shaft pipe is 114 mm, and the rear one is 89 mm. Rigid universal joints are mounted on needle bearings - the same as on KrA3-219/257. The front and rear axle housings are interchangeable. They are not cast, as on their predecessor trucks, but made from sheet steel using the stamping method.

Subsequently, when studying the operation of the KrA3-257, it was concluded that there was no need for a separate drive through 2 cardan shafts. Gradually we came to a less complex drive for the front and rear axles with a middle axle through passage, connected from the cab. The transmission control, in particular the axles, has become push-button rather than lever-based, as before. This simplified the ergonomics of the cabin and improved the workspace. The control panel was moved to the right side behind the pressure indicator area, since it was used infrequently.

The track and distance between the dual rear wheels of the KrAZ-250 have become slightly smaller than that of previous models. The tires were used with a narrower profile, and the track ended up being the same as that of the KrAZ-219. In the suspension, compared to Kra3-219/257, greater softness has been achieved - due to changing the profile of the sheets and installing springs of variable stiffness. The sliding of the ends of the springs on the linings of the rear axle beams has been reduced. Bronze bushings in the balancers were replaced with textolite bushings. The new steering mechanism has an increased efficiency. On the Kra3-219, a worm with a side sector was used as a working pair. And on the KrA3-250 a rolling pair was implemented: a single-thread screw and a nut with a semicircular threading profile. Instead of pneumatic power steering, hydraulic power steering is used.

Compared to its predecessor, the 250 is more advanced in its design and has better performance. Payload has increased from 13.2 tons to 14,575 tons, and top speed has increased from 68 km/h to 75 km/h. The control diesel fuel consumption of the KrA3-250 is less than 3 liters/100 km. KrAZ-250 requires less time and labor costs for its maintenance. The labor intensity of maintenance, in statistical terms, per 1000 kilometers, was reduced from 2.58 to 1.87 man-hours. The standard service life before the 1st overhaul is 200 thousand kilometers (for the 1st category of operating conditions). Since the layout is more modern and rational, it was possible to significantly shorten the car’s engine hood, and this greatly improved visibility, reducing the part of the road invisible to the driver.

A tubular-ribbon cooling radiator is used, which is more durable compared to the previous tubular-plate radiator. The electrical equipment system as a whole has remained without major changes - it is single-wire, with a rated voltage of 24V. However, the lighting technology was brought into compliance with UNECE standards: the headlights moved to the bumper, and the turn indicators to the wings, that is, they “swapped places.” To inform the driver, new light indicators were introduced: high beam headlights, car turns, reduction of air pressure in the pneumatic system receivers, minimum oil pressure in the engine and overheating of the coolant. Instead of four 6STE-128 batteries, two 6STEN-140M batteries were used.

Design changes were also made to the truck chassis components. In particular, a hydropneumatic device was used in the clutch drive, and a pneumatic amplifier was used to disable it. As a result, the force required for the clutch pedal has been reduced by four times. In the 2-speed transfer case, the top gear ratio was increased from 1.00 to 1.23. Thanks to this, it was possible to increase the maximum speed of the car. Compared to the KrAZ-219, the KrA3-250 has smaller dimensions and weighs 925 kg less; and the carrying capacity is greater.

Thus, the new KrAZ differed from the classic trucks of this brand in a number of new and improved components and assemblies. And, above all, what is noticeable at first glance is its appearance: a completely different cabin, tail, and hood. The KrAZ-250 cabin still cannot be called comfortable for work. But still it is much more comfortable than the KrAZ-219/257.

Modification of truck crane KS-4562

The lifting device of the disassembled special equipment is located on a movable platform, and the boom has steel ropes and load grippers. The crane design includes outriggers that provide auxiliary stability during operation. The maneuverability of the mechanism is ensured by the wheelbase of the 250th model, which makes it possible to use the truck crane even in limited space.

Moreover, the crane can be moved to any required area of ​​the construction site. The carrying capacity of this model is 20 tons. The maximum height to which the boom can rise is 10.3 meters. The greatest depth of lowering the load is 4.4 meters. And the reach of the described element is from 3.5 to 12 meters, depending on the configuration of the crane.

Let's sum it up

The KrAZ-250 can be called a well-proven vehicle, which has earned the best reviews for decades as a durable and reliable unit on which you can move and transport cargo over long distances, despite difficult off-road conditions.

This type of machine has not lost its relevance, despite its removal from serial production, which once again confirms that it is perfectly suited to many aspects of construction and other industries. The machine is also used as a crane, and quite often.

This is partly due to its low cost compared to European models. The vehicle has good cross-country ability and fairly high ground clearance, which allows it to pass and work where other trucks might get stuck.

Not to say that the power unit of the KrAZ is very powerful, but it copes with its duties perfectly, but it is very voracious. The high seating position provides the driver with good visibility, and the seat can be adjusted mechanically. It is clear that the level of comfort is minimal, but you should not forget about the price tag that is on this vehicle.

But the machine is not afraid of work in the mining and oil fields, can operate in a fairly wide climatic range and is not afraid of getting dirty. Back in the 20th century, the model managed to win the respect of many drivers, and even today, many years later, it continues to serve faithfully in numerous areas of application.
