Diesel-electric crane SMK-10 and other models of different lifting capacities

Models

All machines have a unified design with separate electric motors for each mechanism. The hydraulic system is installed only on later versions. The crane installation is controlled by levers and pedals from a separate driver’s cabin located on the turntable. The lifting capacity of the machines is 7.5-14 tons.

SMK-7

The SMK-7 crane is an early modification of the machine, which used MAZ-200 trucks equipped with an in-line 2-stroke supercharged diesel engine as a base. On board the crane there was a special cargo winch designed to pull cargo into the work area.

The SMK-7 truck crane was later modernized by moving the installation onto a MAZ-5334 chassis equipped with a 4-stroke diesel engine with a power of 180 hp. The carrying capacity of all options is 7.5 tons.

SMK-10

Diesel-electric crane with a lifting capacity of 10 tons, built on the basis of a MAZ-5334 truck. A special feature of the design are screw outriggers, which are adjusted manually. The equipment was equipped with a 10 m long boom, which allowed the installation of 2 additional sections (3 m each). The design of the crane does not allow for movement with a load suspended on a hook. It is allowed to rotate the tower while lowering or raising the load or boom.

SMK-14

The SMK-14 truck crane, which has a lifting capacity of 14 tons, uses a MAZ-5337 truck as a base. The machine drives are equipped with asynchronous electric motors with an operating voltage of 380 V. The energy source is a generator mounted on a vehicle chassis. The rotor is driven by a power take-off gearbox mounted on the gearbox.

The generator has a distribution box designed for connecting external devices with a total power of no more than 30 kW. It is allowed to power consumers installed on the tap from an external 3-phase alternating current source. The SMK-14 truck crane connected according to this scheme can be used in rooms with poor ventilation.

SMK-101

The SMK-101 crane, designed to move cargo weighing up to 10 tons, is based on the MAZ-5334 commercial truck chassis. The crane installation is installed on a support circuit equipped with hydraulically driven outriggers. The hydraulic circuit includes a gear pump driven by a separate electric motor with a power of 3 kW.

Brief description of the technical characteristics of the machine:

• boom length - 8.6 m;
• extension insert size - 3 m;
• allowed number of inserts - 3;
• jib length - 1.5 m;
• load capacity at maximum boom and jib length - 2.5 t;
• superstructure rotation speed - 0.4-1.7 rpm;
• crane working area - 360°;
• generator power - 30 kW;
• engine power of the main and jib winch - 17.5 kW;
• rotation gear motor power - 4.1 kW;
• average fuel consumption during operation of the installation is 6.46 liters per hour.

Assemblies equipped with rollers or balls are used as a rotary shoulder strap. A stabilizer is installed in the machine’s suspension design, which eliminates distortions of the equipment during operation. On board the vehicle there is a separate winch for pulling loads, equipped with a 4.2 kW electric motor.

Specifications

Thanks to the strengthening of the frame, the vehicle's load capacity has increased. It was 8.2 tons versus 7.5 for the 500th model, on the basis of which the 5334 was designed. At the same time, fuel consumption became 3 liters lower and amounted to 22 l/100 km. I would like to note that these figures directly affect the economic indicators of profitability and transportation in general.

Due to changed safety requirements, headlights were placed on the bumper. However, the turn signals and markers remained on the sides of the radiator grille. This simplified the wiring diagram.

In addition, when driving, the cabin vibrated on potholes. Accordingly, when the headlights located on the front of the old cabin were turned on, a beam of light was pulled. When they were transferred to a rigid bumper, which was part of the frame, this problem disappeared and the beam of light always came out smoothly.

This arrangement of lighting allowed for less glare on oncoming drivers. The grille has also changed. Then the MAZ 500 A had large horizontal slots. And now with small slots, and it has become noticeably wider, which improves engine cooling.

Cabin

It is a three-seat design with a streamlined design and good visibility. The salon is quite spacious, but with a minimal level of comfort. The driver's seat was adjustable - forward/backward and backrest tilt, and it was also equipped with a shock-absorbing mechanism. Separately, it should be noted that there is a sleeping place in the back for long trips.

Thanks to the powerful stove, it was warm inside the cabin even in severe frost. But in hot weather, drivers could only escape by opening the windows, since there was no air conditioning.

The windshield is divided in two by the B-pillar. Because of this, there was no need to replace the whole glass when half was broken. In addition, the cabin rigidity is increased.

Transport management system

The steering was equipped with a hydraulic booster. Therefore, it was possible to turn the steering wheel, located almost vertically, without applying much effort.

By the way, the instrument panel had a well-thought-out layout. Sensors installed on it informed the driver about all the most important parameters. They also notified about possible system malfunctions. And behind the panel near the window there was space for small things.

Engines

For the truck based on model 5334, there was a choice of two engines supplied by the Yaroslavl Motor Plant:

• The first of them is a V-shaped YaMZ 236 with 6 cylinders, power - from 180 to 230 horsepower. The maximum possible torsional moment was 667 N.m. It was achieved at 1500 rpm. Therefore, the engine pulled well at the low end. But there was a serious drawback of the 236th - strong vibrations during operation. The designers partially solved this problem by installing a power unit with a gearbox on three cushions.
• The second is the eight-cylinder V-shaped YaMZ 238, already producing 240 - 300 hp. Accordingly, its fuel consumption was higher. Access to the power unit was achieved by tilting the cab forward. The gearbox used was a five-speed manual. The clutch is a double-disc friction clutch.

Device

The MAZ 5334 had much higher technical characteristics than the 500 series.

The wheel formula of the car is 4x2, the rear axle is driven. In general, the car was designed in such a way that by changing the tire sizes and the number of teeth in the wheel gearboxes, the required gear ratio was achieved. This helped, depending on the purpose of the modification, to increase or decrease this indicator. There was also the opportunity to achieve optimal performance.

The 2-circuit braking system already had a drive divided along all axes. The car's suspension uses extended springs and improved shock absorbers. Thanks to this, the safety and controllability of MAZ has increased.

The main parameters of the car chassis are shown in the table below.

11.15 at 2100 rpm 180 at 1500 rpm 667

Chassis

For stability in the transverse direction, some models use sliding trolleys. The main part is a fixed frame, which is supported by two crawler tracks with a drive. The tracks consist of numerous links and have a large area of ​​support on the ground, which ensures low pressure, only about 0.1 MPa.

Instead of a mechanical drive, modern cranes today have a hydraulic drive. And such models are in good demand. They have two pumps. This allows you to simultaneously perform any operations, for example, lifting and turning, movement without a drop in pressure in the hydraulic system. Any operations on such cranes are performed accurately and smoothly. This is ensured by proportional valves in the hydraulic control. On cranes with hydraulics, the crane operator does not need to exert much effort to operate.

Some of the latest models of crawler cranes on the Russian market are equipped with a telescopic boom. Such an arrow provides a number of advantages. The required length is achieved not by installing additional inserts, but simply by extending the boom. It also becomes possible to transfer cargo in an additional plane.

Until recently, telescopic booms had almost 50% less lifting capacity than lattice booms. But today, ovoid profiles have begun to be used in telescopic booms, which has already increased their load capacity and continues to increase due to new technical solutions.

Moreover, the cost of cranes with lattice and telescopic booms is approximately the same, and sometimes the telescopic version is even cheaper.

In Europe, crawler cranes with telescopic booms are already very widespread.

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.

Find out the technical characteristics of KamAZ-53212, such as load capacity, dimensions, the possibility of equipping with additional equipment, etc. 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.

Internal and external features

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.

The interior space is designed for driver convenience. The seat on special shock-absorbing devices allows you to calmly overcome any bumps and unevenness. Conveniently located, almost vertical steering wheel.

The instrument panel is clearly visible and has a pleasant backlight. Enough space to store personal items and small tools.

The high load capacity and strong driving characteristics of the MAZ-5334 are ensured by the diesel propulsion system of the Yaroslavl Motor Plant.

The base engine is a six-cylinder low-speed V-shaped YaMZ-236 with a power of 150-300 hp. With. In some configurations, when greater load capacity is required, an eight-cylinder YaMZ-238 is installed, which can produce 235-420 hp. With. at the same speed.

A truck crane based on the ZIL-130 is produced by the Likhachev ABK plant. The device with a crane installation can be used in difficult conditions and travel off-road. The vehicles are used to transport heavy loads in bad weather when other vehicles cannot cope with such work. Load-lifting mechanisms of cyclic action can be used not only in construction, but also by fire services.

The equipment can work properly in severe frost. The cranes have a high lifting capacity - up to 6 tons. The advantage of the truck crane is the basic capabilities of the ZIL-130 vehicle. The technique is used both in cities and in remote areas. The device has a long service life.
