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.

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.

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.

Truck crane

One of the installations mounted on the 5334 base is the KS 3577 truck crane, better known as “Ivanovets”.

This is a vehicle-based unit that is designed for a wide range of lifting operations. The main feature of the truck crane is that it has high productivity. Therefore, it is widely used for construction purposes and agriculture.

It should also be noted that the truck crane is characterized by high maintainability and good maneuverability. The installation is capable of moving various loads, including reinforced concrete products, metal structures and timber.

"Ivanovets" was equipped with a trapezoidal support contour. This contributed to an increase in carrying capacity when compared with other machines of this class.

Torque is generated by the power unit through the PTO (power take-off). It is used to rotate the turning mechanism.

Boom and winch design

The MAZ 5334 truck crane with serial number KS 3577 is equipped with a two-section hydraulic boom. Moreover, the moving part is capable of extending to a height of up to 6 m using two hydraulic cylinders, which are connected to each other by couplings.

If you need to increase the lifting height of the hook lift or expand the working area, there is an additional part of the truss structure. The boom design makes it possible to move the load both horizontally and vertically.

The cargo winch consists of:

• drum;
• band brake;
• drum-type hydraulic contactor;
• 2-stage cylindrical gearbox;
• hydraulic motor.

For rotation, a roller support circle with engagement on the inside is used.

Cabin and platform

The crane operator's cabin is located on a rotating platform and is multifunctional. In addition, it is equipped with a ventilation system, an autonomous stove, lighting, a first aid kit and protective visors.

The space is finished with vibration-isolating material. All electrical equipment of the crane is powered by 24 volts. Inside there are devices that control the load capacity, the load on the boom, and also a relay. If the indicators deviate from the norm, the security system is activated, blocking one or another system.

I would like to add that the platform is equipped with four hydraulic outriggers. These mechanisms allow you to fix the truck crane in the required position. This ensures stability during lifting operations.

The Ivanovets truck crane belongs to a light series of truck cranes. KS 3577 technical characteristics exceed those of similar brothers. We will consider the main parameters below.

• Truck chassis called MAZ 5334 (wheel formula 4x2, YaMZ engine with index 236NE2);
• Engine power – 230 hp;
• Boom length – 14 meters;
• Load capacity – 14000 kg;
• The rotation speed of the turning mechanism is 1 rpm;
• The speed required to lift or lower the load is 10 m/min;
• Truck crane weight – 15500 kg;
• Front or rear axle load – 6.1 or 9.4 tf;
• Dimensions 9850x2500x3650 mm;
• The maximum speed of transport is 85 km/h.

Specifications

The mechanical filling was traditionally produced at the Yaroslavl Machine-Building Plant.
For the MAZ-5334, two engine units were designed - YaMZ-236 and YaMZ-238. During the period from 1961 to 1965, a sufficient number of engines were produced for future trucks. YaMZ still continues to produce first-class engines for equipment of the Minsk Automobile Plant. Specifications

Considering the heavy load on the gearbox, the developers took care of the presence of synchronizers, which made it more efficient and durable.
In the clutch basket, the disc had peripheral springs to disconnect the gearbox from the engine for short periods. Dimensions and load capacity

Characteristics of the boom of a truck crane. The boom is built with telescopic sections that extend to a considerable distance. The hydraulics are made conscientiously, continue to serve to this day, and in return only require proper care.

In recent years, a crane of the SMK-101A type was installed on the chassis.
The drive was electric, and the boom was non-retractable. Electrics

Device

The chassis is equipped with a 4*2 wheel shape. The drive is rear-wheel drive. A ladder-type frame, on the rear cross member of which there is a towing device and a plug socket for connecting the electrical equipment of the trailer. To limit the angle of rotation of the trailer drawbar, some models are equipped with bump stops. The chassis serial number is stamped in the area of ​​the right side member.

The MAZ-5334 gearbox has 6 or 8 mechanical gears, one of which is reverse. Synchronizers are installed between stages 2-3 and 4-5.

To make it convenient to operate the power take-off gearbox, a removable hatch for the gearbox housing is provided. Such a device is necessary for the operation of additional devices: winch, pumping station.

The mechanism for transmitting force to the gearbox is provided using a dry double-disc clutch.

The chassis uses an open type cardan transmission system. The ends of the transmission are equipped with hinges with needle bearings.

Torque is transmitted to the rear axle through the wheel gearbox and the main bevel pair.

The brake system is driven by a pneumatic drive. In addition, it is additionally equipped with a compression brake, consisting of a special damper located in the exhaust manifold. The handbrake system uses a conventional shoe mechanism to hold the chassis while parked.

Features of modifications

The basic model MAZ-5334 could be converted into many modifications:

• Automotive cranes;
• Fuel tanks and fuel tankers;
• Dump trucks;
• Tractors;
• Drilling rigs;
• Concrete trucks;
• Emergency rescue workshops;
• Insulated kungs for transporting people.

Truck crane. The main representative of modifications from MAZ-5334 is a truck crane. To secure the vehicle, four hydraulic rotating supports are integrated into the frame. And the frame itself was located on a torsion bar suspension. The boom was a retractable type, but the factory also installed non-retractable ones. It is considered convenient that the crane control is located not on the frame, but in a special cabin. This version of the truck is no less known as “Ivanovets”.

Fuel tanker. No less popular was the modification with a tank for transporting liquid fuel - the MAZ fuel tanker. The system included the following elements: a tank, pumps, filters, a pipeline system with special hoses, sensors for measuring the operation of the system. It is the presence of a pistol that allows not only to transport fuel, but also to use the MAZ-5334 as a tanker. Pumps can be used to pump liquids without using a container. A special model ACM-8-5334 was used for transporting petroleum products (ATsM - AutoTanker-Mazutovoz). Also on the same base at the Tikhoretsky Machine-Building Plant, a modification TZA-7.5-5334 was created for the needs of army automobile battalions. This tanker's flattened tank shape was designed to fit into the cargo bays of Army transport aircraft.

Drilling rig. The third version of the most popular is the MAZ-5334 drilling rig. Modules and equipment for this model were designed and produced in Bryankov. Together with this equipment on board, specialists could make wells up to 500 meters deep. Among the drivers, the MAZ-5334, used for drilling purposes, was called “Mazai”.

Refuelers

From 1980 to 1984, an automobile tank on a MAZ chassis was assembled at the Bataysk Energy-Mechanical Plant. It was called ACM-8-5334. It was a fuel oil tanker for transporting heavy petroleum products.

This article will help you understand the prices of Case tractors.

The following information: https://spez-tech.com/tehnika/selhoz/uborochnaya/opisanie-zernodrobilki-zubr.html contains generalized reviews of Zubr-2A grain crushers and other models of this company.

At the same time, the TZA-7.5-5334 automobile fuel tanker was designed at the Tikhoretsky Machine-Building Plant, which went into production in 1981.

Sixty percent of all production went to the needs of the army - mainly for refueling aircraft. Twenty-five were sent to civil aviation, the rest went to the national economy.

Even the flattened shape of the tank on this tanker is a necessary measure in order for the vehicle to fit into the cargo compartment of heavy BTA aircraft.

Due to the installation of additional equipment in the form of pumps, pipelines, hoses, dispensing units and refueling nozzles, the vehicle weighed up to 16.5 tons.

Today there are quite a lot of offers on the market for conversion TZA-7.5-5334. In Soviet times, military acceptance at factories was very strict in selecting products, even rejecting cars with scratches on the instrument glasses.

Therefore, you can count on the good condition of the offered army vehicles.

The price on the automobile market for fuel tankers is quite reasonable: a car produced in 1987 can be bought for 250,000 rubles, a car produced in 1992 can be purchased for 450,000 rubles.

Advantages and disadvantages

As with most cars produced in the middle of the last century, there are many disadvantages here only for the reason that they are outdated, and the requirements for cars have become much greater.

MAZ-5334 and its modifications are still found in excellent condition, and if you try hard, you can find a car with no mileage from the state reserve. Despite all this, the main disadvantages are that the truck consumes a lot of fuel, and it required a lot of skill and effort to drive it.

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.

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.

Drilling rigs

A number of Russian factories, such as the Bryankovsky Drilling Equipment Plant or Izhmashstanko, at one time launched the production of drilling rigs on the MAZ-5334 chassis. This equipment allows drilling to depths of up to 500 meters or more.

The average price is about 800,000 rubles.

Having studied the supply and demand in today's automobile market, we can say with confidence that the MAZ-5334 car, born back in 1977, still feels confident on the roads of Russia.

The affectionate nickname “Mazai” has long been assigned to him. The undoubted leadership belongs to the MAZ-5334 truck crane, the technical characteristics of which allow us to solve all assigned tasks with high quality.
