Maz 5337: technical characteristics and modifications

Compact and versatile long-lasting truck

MAZ-5337 is a universal truck chassis with a 4x2 wheel arrangement, mass-produced by the Minsk Automobile Plant since 1987.
It is one of the “long-livers” of the domestic automobile industry: modifications of the MAZ-533702 and MAZ-5337A2 chassis are still included in the plant’s production program and the price list of its official dealers. The secret of long life lies, above all, in the extreme versatility of this chassis. and also in the simplicity of design, reliability and unpretentiousness of the car itself. And, of course, at a very reasonable price for this, in all respects, a long-outdated example of the Soviet automobile industry. Compact dimensions for a vehicle of similar carrying capacity, maneuverability, and low operating costs allow the MAZ-5337 to be used effectively and with high profitability in almost all sectors of the national economy. On paved roads this truck is truly versatile. It is designed for transporting any cargo in urban conditions and on intercity routes. It can be used either independently or as part of a road train. True, this model is of little use for unpaved roads due to its axial load.

Options for add-ons on the MAZ-5337 chassis

City utility companies operate garbage trucks and various types of municipal equipment on the MAZ-5337 chassis. (Although more often “communal trucks” are made either on the basis of the MAZ-5432 saddle truck or the MAZ-5551 dump truck). At construction sites of various sizes, MAZ-5337 with crane equipment on the chassis is very often found. In particular, a popular option is the KS-35715 truck crane, with a lifting capacity of 16 tons.

Tanks for food and non-food liquids and fuels and lubricants, hydraulic manipulators, drills, suction trucks and other equipment are mounted on the same chassis. MAZ-5337 can (albeit rarely) be found in the vehicle fleet of fire departments, and as vehicles for other emergency services. Refuelers based on the MAZ-5337 can be seen at airports in Russia and the CIS.

The truck is unpretentious, it is designed to work both in extreme summer heat and in severe frosty winters. There is a special version of the vehicle for oil and gas production companies, specially adapted to the conditions of the Far North, Siberia and the Far East: MAZ-533701 (version “HL”, for operation at minus 60 degrees Celsius). In this northern modification, the cabin is extended, with two berths. Another popular Soviet truck, the KamAZ-5320, is the car’s closest “relative” and competitor.

Device

The tank with which this variation of special equipment is equipped has a special marker and a breathing valve. The first is installed to show the level of fuel transported inside the container. The presence of a breathing valve eliminates the risk of excess pressure. Drain pipes are connected to the tank. They are equipped with quick-acting valves and special settling tanks with a water separating system.

Provided that the volume of the tank exceeds 5000 liters, the tank is additionally equipped with breakwaters located perpendicularly and longitudinally relative to the hull. The presence of these elements ensures a reduction in hydraulic shocks during liquid transportation.

The internal space of the tank can be divided into two sections. Two-section tanks can transport different types of fuel or gasoline with different octane numbers.

The MAZ chassis is produced using various wheel formulas. Already in the basic configuration, fuel tankers are equipped with spring and air suspension.

MAZ fuel trucks have a frame design. The container is located on this frame. Here we can talk about the maximum strength and reliability of the entire assembly. Thanks to the high quality of connections, the fuel truck feels very confident on roads with any surface quality.

Cargo platform and trailer MAZ-5337

The body of the MAZ-5337 onboard vehicle is a metal platform with opening side and rear sides. The side board consists of two parts. The flooring of the loading platform is wooden. The main trailer for trucks of this model is MAZ-8926.

The KI 5426-11 van is made of sandwich panels, the outer skin is made of painted steel or aluminum sheet; internal lining: painted steel or aluminum sheet. The floor covering is made of corrugated aluminum sheets, treated with polyurethane filling. The rear doorway is made of painted steel or stainless steel. The fittings are all painted.

Van KI-5426 (but in this photo - not on the chassis of the “big” MAZ-5337, but on the chassis of the “Zubrenok” MAZ-4370).

The interior dimensions of this van are as follows. Length - 5.2 m; width - 2.4 m; height - 2.0 m. The internal volume of the KI 5426-11 van is 26 cubic meters.

Electrical system characteristics

The power supply in the MAZ 5337 car is organized according to a single-wire circuit. Using the G-273V generator, a voltage of 24 V is created. The operation of the generator is controlled by a built-in voltage regulator. The starter type ST103-A-0, which starts the engine, is powered by two series-connected lead-acid batteries 6-ST-182EM.

• MAZ-5337-01(HL) is an on-board vehicle designed for operation in conditions of ultra-low temperatures (down to -60*C).

Common special vehicles based on the MAZ-5337 include:

• MKDS-3410 is a combined road machine that includes watering equipment, a universal plastic tank, a rotating sectional blade, a snow brush and a road reagent distributor;
• MB-15 – garbage truck;
• G6-OPA-7.5 – tank truck for transporting food liquids (water, milk, wine, alcohol-containing liquids, etc.). Thermal insulation allows you to prevent changes in the temperature of the liquid by more than 2 degrees for 10 hours, with a difference in temperature between the liquid and the environment of about 30 degrees.

The MAZ-5337 is based on a classic “ladder” frame, made of high-strength steel, on which the cabin is rigidly mounted and all the main components and assemblies are installed.

Main components of boom equipment

Boom equipment

Traditionally, like most truck cranes, the KS-3577 model is equipped with a telescopic boom design. The lifting organ itself consists of two parts: a fixed one, hinged to the support, and a movable section, which can be pulled out. The lifting of the main supporting part of the boom is provided by the main hydraulic cylinder. Two hydraulic cylinders connected to each other using a coupling are responsible for extending the second section.

Boom extension

A jib or extension is provided to increase the working space under the boom, as well as the height of the latter. In the KS-3577 truck crane, this element is made of rolled metal (angle) and is attached to the head of the retractable boom section using special brackets. The jib can be transported on the KS-3577 itself, attaching it next to the boom to its side plane.

Operator's room, truck crane rotary unit, lifting body

KS-3577 is a lifting system that operates hydraulically. The working bodies are driven by a hydraulic pump, which itself is connected through a box to the power take-off shaft of the vehicle. The crane operator can use a special lever in the cabin to disconnect the pump from the drive.

Platform rotation mechanism

The unit is made on the basis of a hydraulic motor, which is connected to a two-stage gearbox. There is also a shoe type brake and a hydraulic release. The output part of the gearbox has a gear on the shaft. The latter engages with the turning-support circle via a gear ring. The rotating part of the truck crane can be rotated manually using a handle. To do this, there is an intermediate shaft with a gear with a shank at the end.

Crane operator's cabin

The driver operating the KS-3577 truck crane is in a special cabin during lifting operations. All machine controls are located in this workroom. The cabin is equipped with lighting equipment, a cooling fan, and has spacious viewing windows. For work in winter, the workplace is heated; the cabin body itself is thermally insulated.

Lifting mechanism

The cargo winch is driven by a hydraulic motor through a two-stage gearbox. It itself has a drum with a braking method through a band brake and a hydraulic release. The drum communicates with the hook suspension through a special cable.

Engine MAZ-5337

The car of this brand is equipped with V-shaped six-cylinder diesel engines of the YaMZ-236 family: YaMZ-236M2-1 - without turbocharging, YaMZ-236NE2 (Euro-2) and YaMZ-6563.10 (Euro-3) with turbocharging. The working volume of any of these diesel engines is 11149 cm³, and the power is 180 hp/132 kW (YaMZ-236M2-1), at 2100 rpm; 230 hp/169 kW (YaMZ-236NE2 and YaMZ-6563.10), at 1900 rpm. The last two modifications use the CommonRail electronic injection control system.

The torque of the YaMZ-236M2-1 motor is 667 Nm (68 kgf-m) at 1250-1450 rpm; for YaMZ-236NE2 and YaMZ-6563.10 this figure is 882 Nm at 1100-1300 rpm.

YaMZ-236NE2.

The high-pressure fuel pump in the YaMZ-236M2-1 is a 6-section, spool-type with a low-pressure fuel priming pump, a fuel injection advance clutch and an all-mode speed controller. The engines are equipped with an electric torch device (EFD) and, as an additional option, a PZD-30 pre-heater.

The car accelerates to a maximum speed of 85 km/h provided by the manufacturer. Acceleration time to “cruising” speed of 60 km/h is about 50 seconds. For 100 km of travel at a speed of 60 km/h, a MAZ-5337 vehicle consumes about 20-22 liters of diesel fuel.

Cabin and steering

Unlike previous MAZ families with noisy, cold cabins and low-quality glazing, the characteristics of the latest modification 5337 indicate a comfortable interior. The cabin is different:

Cabin MAZ-5337

The cabover cab located above the engine is a two-seater cab without a berth, but a third seat can be installed. A cab with a berth is also found on some used trucks of this model: previously in serial production there was a modification of the MAZ-53371-29 - with an extended cab. For engine repair and maintenance, the cabin tilts forward using a hydraulic cylinder with a hand pump. The driver's seat is sprung, with a range of adjustments for length and height; by the inclination of the pillow and backrest.

Main features

Now you can criticize MAZs of the 500 family for a long time for their noisy engine, stiff suspension and a bunch of other design flaws. However, it must be taken into account that for its time it was a promising machine with a huge resource of components before major repairs. It was famous for its indestructibility and maintainability.

The truck with serial number 5334 was loved by both drivers and mechanics. It was widespread throughout the entire USSR from Kaliningrad to Kamchatka, from the Far North to the Caucasus.

In addition, the car was exported and was well known in many countries, such as Hungary, East Germany, Cuba and others. The production of this model has long been discontinued. However, there is still no, no, and the blue and yellow “Ivanovets” will rush by. You can immediately feel the combination of strength and power in him, which is aimed at peace, creation and service to people.

To buy a MAZ 5334, you need to try really hard to find it. A used truck will cost 120-150 thousand rubles. In good condition and running, prices start at 350 thousand rubles.

Peculiarities

MAZ-5337 is one of the most popular models of the Minsk Automobile Plant. Moreover, this model is in great demand today. This is explained by the fact that despite its simplicity, the truck is truly very reliable. The engine, gearbox, suspension and other elements are capable of withstanding impressive loads, which has been repeatedly confirmed in practice. The engines have quite high power with economical fuel consumption.

The presence of many different add-ons allows the vehicle to be used in many areas, including construction, agricultural and municipal services, emergency services and others. And the relatively compact overall dimensions give the model excellent maneuverability, which is the most important parameter when working in cramped conditions.

In addition, the owners note maintainability, unpretentiousness, and, of course, accessibility.

Reviews from owners and drivers of MAZ-5337

Without a doubt, the MAZ-5337 is an outdated model. The driver's working conditions are acceptable for the late 80s of the twentieth century, but very spartan for the modern era. The cabin is noisy, and its vibration protection from the engine is also weak by modern standards. The design, naturally, does not “shine” either in appearance or interior. But: this is an unpretentious working machine, the price of which is not exorbitant. With competent and caring attitude, the MAZ-5337 will pay for itself quite quickly and many times over.

Suspension, wheels and tires

The series uses an improved front and rear suspension system:

• The front suspension springs , combined with two telescopic shock absorbers, have a semi-elliptical shape, their rear ends slide smoothly;
• two main and two additional springs of the rear suspension are semi-elliptical in shape. The rear ends of the main springs and both ends of the additional springs are sliding.

The wheels with 8.5V-20 rims used in the MAZ-5337 truck have a discless design. Each is fastened with clamps on 6 bolts. Radial tires can be installed: 11.00R20 (300R508), I-68A, I-111A or I-111AM.

Price of new and used MAZ-5337

The cost of the new MAZ-5337 (chassis) in 2022 starts at 2 million 650 thousand rubles. On the secondary market there are many offers for the sale of used trucks of this model, with various chassis add-ons. The range of prices asked for them is very large, from 200 thousand rubles to 1.5 million rubles. It all depends on the year of manufacture and technical condition of each specific car.

A common option is the Kupava type van, with a KI 5426-11 body. This inexpensive option for heavy-duty vans, which combines reliability and ease of use, is widely used for intercity and intraregional transportation.

According to the testimonies of drivers, the MAZ-5337 withstands difficult operating conditions well, and only minor breakdowns. The YaMZ motor and gearbox and axles operate flawlessly and are easy to maintain and repair. There are no problems with spare parts for the MAZ-5337, and their price is low. There is poor build quality and a lot of defective parts in cars of this brand produced in the second half of the 90s - early 2000s. Further, these indicators were “pulled up” to an acceptable level.

Load height characteristics of the crane

The KS-35719-5 “Klintsy” truck crane with a lifting capacity of 15 tons, mounted on the MAZ-5337 chassis, is designed for loading and unloading and construction and installation work at dispersed sites. Excellent maneuverability and ease of chassis control, small dimensions make the truck crane indispensable when used in cramped conditions of modern cities. Crane drive - hydraulic

, is carried out by means of an axial piston hydraulic pump, which is driven by the engine of the base car through the transfer case and additional power take-off. The crane mechanisms have an individual drive with independent control from hydraulic motors and hydraulic cylinders. The hydraulic system of the crane installation ensures smooth control of all mechanisms with a wide range of speed control for working operations, and provides the ability to simultaneously combine three crane operations. The crane is equipped with hydraulic outriggers with retractable support and beams.

Two-section telescopic

an 8-14 m long boom provides the truck crane with compactness and maneuverability when moving, a wide working area and a large height of cargo movement during operation. To increase the service area and the size of the boom space, the truck crane can be equipped with a lattice jib 7.5 m long. In the transport position, the jib is rotated and secured to the side of the truck crane boom. The transfer of the jib from the transport position to the working position and back is done manually without the use of additional lifting equipment.

Safe operation of the crane is ensured by a complex of instruments and devices, including a microprocessor load limiter with digital indication of operating parameters on the display in the driver’s cabin. The device automatically protects the crane from overload and capsizing, is equipped with a crane coordinate protection system necessary for working in cramped conditions, has a built-in telemetric memory unit (“black box”) and a crane protection module from dangerous voltage (MZON) for operating the truck crane near power lines.

Reference: The KS-35719-5 truck crane was mass-produced by the Klintsovsk Truck Crane Plant from 2000 to 2005. Previously, the crane was produced at the OJSC Galich Truck Crane KS-35719-5 Klintsy enterprise. It is distinguished by minor design changes that are technological in nature and due to adaptation to the production capabilities of another enterprise.

Car history

In 1977, in step with global progress, production of the new MAZ-5334 truck began. The model was developed on the basis of the MAZ-5335. As always, the need for freight transportation increased in the rapidly growing republics of the Soviet Union. Along with this, the requirements for transporters also grew. In addition, due to the industrialization of cities, more modern vehicles were required to service them.

In order to solve this issue, this heavyweight was developed. A special feature of this MAZ is the ability to install various modular superstructures, structures and bodies for various purposes. Also, the technical characteristics have become more superior than those of previous versions of cars. Along with the carrying capacity, traction power has also increased, and there has also been a progression in maneuverability and speed characteristics.

All about the crane installation KS-3577

A multifunctional and universal truck crane came off the assembly line of the Ivanovo Automobile Plant. The base vehicles to which this crane equipment was supplied were the following models: MAZ-5334 and MAZ-5337.

Advantages and disadvantages

Equipment owners note positive features:

The disadvantages include:

• leaks of the hydraulic system through the joints of the lines;
• corrosion of machine components, especially cabins;
• low level of comfort in cabins;
• lack of air conditioning.
