• the possibility of using the trailer brake system as part of a road train;
• voltage value and the presence of appropriate connectors for connecting electrical appliances.

The metal truck platform mounted on the chassis has sides that open on three sides. At the same time, the side ones consist of two parts, which makes loading and unloading operations at a height of 1.4 meters convenient.

The platform flooring is made of durable, rot-resistant wood.

The general demand for truck cranes is related to their mobility, ability and ease of maneuver, ease of installation and operation, etc. The famous “Ivanovtsy” can serve as an example.

A wide range of models with different load capacities, types and lengths of cargo booms are installed specifically on the MAZ-5337 biaxial chassis. An important component is their cost: it compares favorably in combination with the high quality of the equipment.

Today, a good new truck crane can be bought from 3 to 6-7 million rubles, depending on its technical characteristics.

A feature of all crane superstructures on the MAZ-5337 is the complete development and absence of “raw” components and elements in the design.

High-quality hydraulic systems ensure perfectly smooth and precise movement of objects weighing up to 32 tons.

A modern cargo boom, driven by a chassis power plant, is, as a rule, a retractable telescopic structure of 3-4 sections with a hydraulic cylinder and reinforcing pulleys.

This ensures compact installation when moving and a significant (up to 22.5 m) lifting height of the load on the work site.

Truck cranes based on MAZ-5337 have a number of advantages:

• the installations are reliable, safe and easy to operate, their crane operations can be combined;
• ease of control and a wide choice of operating speeds are complemented by the presence of a computer unit that controls the main parameters (loading, height, boom reach and length, working area);
• versatility in repair and the ability to use fuel of various qualities.

MAZ-5334 - technical specifications, review, photo modification

Development based on the MAZ-5335 chassis - MAZ-5334 truck. A more modern truck from the late 70s of the last century. Description of appearance, changes compared to the previous version. Features of the three most popular modifications, their technical characteristics and areas of purpose. The entire MAZ model range.

Exterior and interior

Due to its rounded shape, the cabin has good aerodynamic properties for a car from the 70s. It was decided to place the headlights on the bumper instead of the body. The main light lamps are now much larger than the side lamps. A false radiator grille was placed in front of the radiator, the design of which ensured the supply of the required volume of air. Such solutions simplified the installation of power cables and improved the strength of the body. And, of course, the beam of light began to illuminate the road more rationally. Changes in the radiator grille increased the efficiency of the engine cooling system.

The windshield consists of two sections, with a vertical metal partition between them. This adds safety to the car and reduces the cost of repairs. This became possible due to the fact that if one part is damaged, the second remains intact. Otherwise, there were no significant changes compared to previous models. Some elements have slightly changed their positioning or appearance, which does not affect the overall picture.

The interior has also become more modern and equipped. The steering wheel is located almost vertically at an angle of approximately 20 degrees. The work of the suspension is complemented by the shock-absorbing system of the driver's seat. Thanks to this, even when driving on roads where even springs cannot cope, driver shaking is reduced to a minimum.

The dashboard is equipped with all the necessary sensors, including sensors for speed control, engine systems and its temperatures, as well as pressure sensors in existing systems. All measuring sensors are backlit.

The most interesting is the presence of roll, voltage and boom position sensors. The system also has a built-in weight limiter.

At the top of the dashboard there is space between the slope and the glass. This place can serve as an excellent warehouse for various things: from the driver’s personal belongings to small spare parts or tools.

Let's sum it up

The conveyors of the Minsk Automobile Plant produced model 5334 and its modifications until the mid-90s. High-quality exhibits became leaders in production, setting records in their time and helping achieve their goals. Now these trucks are still working at enterprises throughout the post-Soviet space.

Nowadays you can buy a used car in excellent condition and maintain it with proper care. As already mentioned, you can even find representatives that were not sold and were stored in warehouses. The average price of any type is about 800,000 rubles. By purchasing this security officer, the owner can be sure that the car will serve for a long time and faithfully, fulfilling the assigned tasks.

MAZ-5337 work

Modifications of MAZ-5334 and technical characteristics of the base model

The production vehicle with a flatbed body, produced in the late seventies, was called MAZ-5335.

It was a fairly good modification of the previous 500 series. The chassis of the base car was labeled MAZ-5334. It was intended for the manufacture of special cargo transport.

On the basis of this chassis the following were manufactured:

• truck cranes,
• fuel tanks and fuel tankers,
• dump trucks,
• tractors,
• drilling rigs,
• concrete trucks,
• emergency rescue workshops,
• insulated kungs for transporting people.

Internal and external features

Important! The main external difference from previous cars was the transfer of lighting equipment from the cab body to the bumper and the installation of an improved radiator grille. This made it easier to access the lights and lay electrical cables to them, and also increased the strength of the cabin.

Drivers, in addition, believe that by lowering the headlights lower, the designers improved the illumination of the roadway. A well-thought-out grille design with wide openings has improved engine cooling.

A characteristic feature of the cabin is the windshield, divided in the middle by a narrow vertical partition.

Compared to the design of modern heavy-duty trucks, it looks somewhat unusual, but this has a certain advantage. If one of the glasses is damaged, the second remains intact.

And this also affects the strength of the body for the better. The rounded contours of the cabin have a positive effect on the aerodynamic properties of the car : less turbulence is formed during movement and strong side winds.

Cabin and steering

For experienced drivers who worked on Belarusian cars, the 500 series of the MAZ family was remembered as not having the most comfortable working conditions.

The cabin was noisy, cold, and the glazing was problematic, especially the front glass.

In general, long-distance flights became a real pain. The workplace in the 5337 series is characterized by modern comfort. Thermal and sound insulation of the standard interior has been improved, and an effective heating and ventilation system has been used.

The two- and three-seat cabins located above the engine are equipped with a hydraulic cylinder with a hand pump to tilt them forward when access to the engine is necessary. The driver's seat has a sprung base.

Its design allows you to adjust the distance to the controls, seat height, and the angle of the seat cushion and backrest.

Most models do not have a berth in the cabin. But in some modifications (MAZ-533701 HL) there are up to two sleeping places.

Cars with this marking can be used in the Far North, where temperatures often drop to -60 degrees Celsius.

Important! The dashboard and all interior trim elements meet safety requirements in their modern sense, that is, they have special linings that serve to absorb impact energy.

Rear view mirrors, a system of internal cabin lighting devices, a power steering column, etc. were made taking into account the same requirements.

Convenience and ease of control of a heavy machine is ensured by a complex that includes a rack and pinion mechanism and a hydraulic booster, consisting of a distributor in the steering wheel and a booster cylinder.

The cabin glazing uses a panoramic windshield, curved and solid, providing an excellent view of the road. High-quality seals on windows and doors prevent moisture, dust, etc. from entering the cabin.

When the machine moves, special air intake flaps create air flows along its side surfaces, preventing them from becoming dirty. The all-metal body is welded from steel elements with a protective coating.

Priming and dip painting, in combination with other processing methods and timely maintenance, provide long-term protection of the cabin from corrosion processes.

Device and purpose

The MAZ-5334 base chassis is equipped with a YaMZ-236 engine with a power of 180 hp. With. The car uses a 5-speed manual transmission. The rear axle is equipped with additional planetary gearboxes located in the wheel hubs. Due to this solution, it was possible to reduce the dimensions of the axle gearbox and expand the capabilities of the chassis.

To accommodate the crane installation components, a supporting platform is used, mounted on the rear of the chassis. The platform frame is welded from steel profiles of various sections. A turntable is installed on top, on which the crane boom, auxiliary equipment, cabin and counterweights are located.

To drive the winches and the rotation gearbox, a distribution module is used, which ensures reverse operation of the units. The winches and gearbox are driven by hydraulic motors. The boom angle is adjusted using hydraulic cylinders equipped with a hydraulic locking device. Hydraulics are used to change the length of the boom. Some crane models are equipped with a 3-section boom with a mechanical drive for extending the outer section.

The winch is equipped with a 2-speed gearbox. The unit is braked by a band brake equipped with a hydraulic release. A similar unit is used in the drive of the turning mechanism. If the hydraulics fail, the crane tower can be rotated manually using a special handle.

The hydraulic units of the crane are driven by a gear oil pump. The pump receives rotation from a cardan shaft attached to the output of the power take-off. The selection is carried out from the gearbox. The selection is activated by a separate lever located in the chassis cab. The supply of fluid necessary for hydraulic operation is located in a separate tank. All nodes of the system are connected by rigid or flexible highways.

The use of a sectional boom allows the machine to be used for loading or construction work in cramped conditions.

The telescopic boom provides equipment with the ability to maneuver in narrow passages between warehouses or buildings under construction.

The operator's workplace is located in a separate cabin. The instrument panel is equipped with indicators of the position of working parts and an alarm. The cabin is equipped with a ventilation unit with the ability to supply warm air. Next to the cabin there are crane mechanisms covered with a protective metal casing.

• maximum torque - 667 Nm;
• six-cylinder engine;
• gearbox - manual, five speeds.

The presence of a hydraulic drive and power steering ensures easy control of the crane on the MAZ chassis.

The front axle is steerable.

The MAZ chassis engine drives a hydraulic pump, which, in turn, moves the boom, and the hydraulic cylinder moves its section.

The boom can be extended using an additional lattice extension called a jib. This sectional telescopic design provides the crane with not only the ability to cover a large space and height when moving loads, but also compactness and ease of movement.

The Ivanovets MAZ 5337 crane is equipped with instruments and devices that ensure the safety of its operation. These include a microprocessor-based load limiter, which allows the operator to monitor all operating characteristics on the display in the cab.

These devices determine:

• current permissible load weight;
• the reach of the arrow, the height of its tip;
• crane loading;
• weight of the load suspended on the hook;
• crane operating area. If work is carried out in a confined space, the system can maintain the specified limitation parameters and record them throughout the entire service life of the crane.

When choosing a crane to perform any specific work, you need to focus on its technical capabilities, the conditions in which it will have to work, the possibility and timing of delivery of the machine to the work site.

For work in cramped conditions, the reliable, compact and maneuverable Ivanovets KS 35715-2 truck crane has proven itself well.

The crane can lift a load of up to 17 tons.

A telescopic boom of two sections, having a length of 8–14 m, is supplemented, if necessary, with a jib, increasing it by another 7 meters. The boom radius ranges from 1.9 to 13 m.

Technical characteristics of the crane Ivanovets KS 35715

The load can be lifted to the following height:

• 5 meters - without jib;
• 6 meters - using a jib.

Turning is carried out at a speed of 2.5 rpm.

The load lifting speed is 9 m/min, and with light weight it can reach up to 18 m/min.

Moving at speeds of up to 60 km/h, the crane will quickly arrive at the job site.

Dimensions: 10x2.5x3.85 meters.

Dimensions of the Ivanovets KS-35715 truck crane based on MAZ 5337

An electronic load limiter installed on a MAZ truck crane performs the functions of boom extension warning and loading control. The working unit of the lifting mechanism is a boom consisting of several links. Their number can vary from 3 to 5. The boom is equipped with an autonomous drive, a load grabber with a trolley that moves along it. The links are welded elements made of heavy-duty steel sheets.

MAZ-5337 series and its technical characteristics

The 5337 series uses multi-level braking systems driven by pneumatics.

The efficiency of their operation is ensured when moving at a speed of 60 km/h, slowing down and completely stopping a multi-ton road train - over a distance of only 36.7 m.

All equipment of combined systems has two independent circuits, separate for the front and rear pairs of wheels.

Traffic and parking safety is ensured by:

• drum-type service brakes with a width of 160 mm, a diameter of 420 mm and cam release devices. The brake chambers at the rear have additional spring accumulators;
• parking brake (activated by pneumatics in the rear wheel chambers on spring energy accumulators);
• spare brakes (combined with parking brakes). It is recommended to use when all others fail;
• Special flaps in the exhaust gas exhaust system, activated by pneumatics, provide the function of auxiliary brakes, slowing down the engine speed.

When working as part of a road train, combined options for activating trailer brakes (one- and two-wire) are provided.

There is protection against blocking in case of freezing of accumulated condensate.

The first samples of MAZ-5337 rolled off the assembly line in the second half of the already distant 80s of the last century.

The trucks and chassis of this car model have become an example of the successful implementation of the conceptual idea of ​​unifying structural elements.

MAZ-5337 has a multi-level brake system that operates under the influence of a pneumatic system. They function effectively at any driving pace, for example, if the car is moving at a speed of 60 km/h, the vehicle will come to a complete stop after pressing the corresponding pedal after 36.7 m.

All systems are created on the principle of combination; they have 2 circuits that function independently of each other, ensuring the correct movement of the rear and front pairs of wheels.

Brake system

The guarantee of vehicle safety during idle driving is guaranteed by:

1. Drum brakes. Their width is 16 cm, the diameter as a whole is equal to the parameter 42 cm. The design uses cam-type expansion devices. The brake chambers are equipped with spring-type accumulators, which are located on the rear of the structure.
2. Parking brake. Its connection is carried out using a pneumatic system in the area of ​​the rear wheels, since spring-type batteries are used for this.
3. Spare brakes. They have a combined design with a parking lot. They are usually used when other systems fail.
4. Auxiliary brakes are a rotary retarder with a pneumatic drive. They are presented in the form of dampers, which are located inside the structure of containers with equipment for removing exhaust gases from spent fuel. With their help, if necessary, the motor activity is partially slowed down.
5. The rear brake chambers are equipped with spring energy accumulators.
6. The trailer brake drive is combined (two- and single-wire). There is an alcohol fuse against condensate freezing.

It is possible to connect a system for automatically applying several brake systems. Typically, drivers use this function when driving a car as part of an entire road train, using it to design a trailer.

The system includes protection against blockages, with which there is no risk of system failure in the presence of frozen condensate.

Versatility of technology

Carrying out several jobs simultaneously for special equipment has become an urgent requirement. Therefore, a MAZ car with a manipulator in the current conditions becomes a tempting purchase. An installed crane at MAZ can greatly reduce the scope of work, saving time and your costs. In companies involved in various types of construction, transport industry, landscaping, MAZ with CMU is indispensable. The vehicle will be able to transport various cargoes, reducing the need for labor and not requiring the involvement of other equipment during loading (unloading), and perform the function of a crane in construction.

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.

Power and consumables

The on-board voltage of 24 V is provided by the G-273V generator, the operation of which is monitored by the built-in voltage regulator Y120M.

Starting the engine is ensured by the ST103-A-0 starter, powered by two 6ST-190A (6ST-182EM) batteries.

The standard fuel tank, holding 200 liters of diesel fuel, provides an autonomous range of 450 to 900 km, depending on the load and configuration.

The total amount of oil in the engine is 25 liters of all-season M-6/10B (or M-10B in summer and M-8B in winter). Antifreeze A-40 is recommended for use in the cooling system; its total quantity is 29 liters.

Description and scope of application of MAZ-5337

The base of vehicles with a 4x2 wheel arrangement is 3.95 m. The load capacity of the system is 8.7 tons (this is slightly higher than that of the MAZ-53366), while the curb weight corresponds to the parameter 7.15 tons. The front axle of the unit can withstand a load of 6 tons The axle located on the reverse side can move a large mass of 10 tons.

Towing platforms

If necessary, platforms are towed. When implementing it, the following parameters should be taken into account:

1. Maximum weight of additional load (materials or goods transported).
2. Features of the construction of the device, which ensures reliable grip.
3. The use of a trailer braking system when using a vehicle in a road train.
4. Voltage and number of connectors, their sufficiency to include a full range of electrical appliances.

The truck platform is constructed of metal. It is mounted on the chassis. If necessary, you can open 3 of its sides in different directions. The side segments fold into two different parts, allowing loading and unloading of goods to be carried out comfortably, despite the height of 1.4 m.

The floor can be laid from fairly durable types of wood that are resistant to putrefactive processes.

Cabin dimensions

Many drivers working on Belarusian-made MAZ 500 series vehicles (see here) note that they remember these units as not very comfortable, so working on them is quite difficult. The cabin is not equipped with sufficient soundproofing materials.

Wheels and tires

Wheels - discless, rim 8.5V-20, fastening - 6 bolts with clamps. Tires – 11.00R20 (300R508) mod, I-111A, I-111AM or I-68A. Front wheel tire pressure – 7.5; rear – 6.7 kgf/cm. sq. Number of wheels 6 1.

Also, the glazing was of insufficient quality; in particular, many note the unsatisfactory parameters of the first glass.

The models in this series did not stand out for their functionality and were not convenient, especially when traveling long distances. Series 5337, on the contrary, is characterized by comfort and high-quality adjustment of all necessary parameters.

The interior filling has been modernized, thanks to which new heat and sound insulation has been applied. The cabin is equipped with a heating system developed using new technologies, and there is also full ventilation.

Cabin MAZ 5337

Cabins with 2 and 3 free seats are equipped with a hydraulic cylinder, which is operated using a hand pump. If you need to gain access to the motor, you need to fold out this element. The base of the driver's seat is of a sprung type.

This design reduces the distance from functional devices to control elements of the structure. The driver has the opportunity to configure the cabin as it suits him. It is possible to adjust the seat level, the amount of backrest tilt and the main part of the structure.

Usually the cabin is not equipped with a sleeping place (unlike the ZIL-5301), however, there are modifications that provide the possibility of rest for two people at once, for example, MAZ-533701 HL. This marking of vehicles indicates that these vehicles can be used even when working in the Far North.

Driving a truck is allowed even at an ambient temperature of -60 degrees.

The instrument panel is equipped with maximum compliance with all basic design safety regulations. A variety of pads are used to absorb impact energy.

Many people who are concerned about the aesthetics of the vehicle have a question: where is the frame number on the MAZ-5337{q} They can be seen on the back of the vehicle, as they are located near the right wheel.

Higher quality requirements are also applied and implemented in the production of rear-view mirrors, lighting installation technologies for various elements of the internal control system, and the hydraulic booster located on the steering column structure.

Power steering

This unit is quite heavy, but it is quite easy to operate thanks to the presence in the system of a developed hydraulic booster, a booster cylinder and a rack and pinion mechanism designed according to all the rules.

In the process of glazing the cabin structure, a windshield of both curved and flat shapes was used, which made it possible to obtain excellent visibility of the surrounding space for the convenience of the driver. Functional seals are placed on the structure of windows and doors.

With their help, they ensure reliable blocking of dust, dirt, and water from entering the structure in the event of strong air humidity or rain.

On the outer surface of the cabin there are universal air intake flaps. They exhibit high functionality when moving a vehicle. With their help, air flows are formed that pass along the walls of the machine, preventing them from becoming too dirty.

The body of the structure is made entirely of metal and has a high-quality protective coating.

The developers approached the issue of protecting the structure from corrosion very carefully and responsibly. A high-quality priming process was carried out, and dip painting was also carried out. All these aspects help ensure that rust will not appear for a long time even in difficult operating conditions.

Steering

The steering mechanism is a screw and a ball nut-rack that engages with the gear sector. Send number – 23.55. The power steering consists of a distributor built into the steering mechanism and a separate power cylinder. Oil pressure in the hydraulic booster is 95-110 kgf/cm. sq.

Clutch adjustment

There are several adjustment parameters in the MAZ-5337 that relate to the correction of the clutch position:

• Assigning parameters for the withdrawal of a medium-sized disk to create the necessary gaps.
• Assigning parameters for the adjusting nut and the end of the valve cover in order to ensure optimal clearance between them.
• Assignment of parameters to control the freewheel function of the medal responsible for the clutch.

Features of adjusting the drive disk located in the middle of the structure:

1. Unscrew the clutch and flywheel housing covers.
2. Place the gear lever in the free position.
3. Return the 4 adjustment screws to their standard position. To do this, you need to unscrew the locknuts and turn the flywheel.
4. Continue turning the flywheel while unscrewing the adjustment knob.

The free play of the clutch pedal must be adjusted in the following sequence:

1. Disconnect the double-arm lever.
2. Move the cylinder piston to its extreme position, and move the lower edge of the double-arm lever again until it stops.
   It is necessary to achieve a position in which the lever and the holes of the rod fork do not converge by approximately 50%. If the deviation does not correspond to these parameters, it is necessary to adjust the difference by rotating the rod.
3. Combine the lever and yoke of the cylinder rod, as well as with the valve stem, maintaining the lowest position. To adjust the distance between the two forks, you need to rotate them until the desired parameters are achieved.
