Rent of crawler crane MKG-40 in Samara

The MKG-40 crawler crane is an assembly crane equipped with a combined power unit, mounted on a crawler base with the ability to move independently around the construction site. This crane is capable of lifting a load weighing up to 40 tons on a boom. The popularity of this mechanism is due to the ability to quickly and easily change attachments, increased lifting speed, good performance and reliability of the equipment.

Cranes can be used for lifting and moving cargo around a construction site, installing reinforced concrete and metal products, and during loading and unloading operations.

Let us dwell on the most important features of the type of lifting equipment under consideration:

The crane does not have complex hydraulic units or automated systems, which often break down and cause equipment downtime.
The presence of a combined power unit made it possible to simplify the mechanical part of the crane and remove some mechanical and hydraulic components. This simplifies the operation of the crane.
Thanks to the wide track base, the crane exerts little pressure on the ground, which allows the mechanism to easily move across unprepared areas.

Lifting equipment

The set of boom equipment to support installation work is basic for the MKG-40. The kit includes the main boom, extensions, jibs.

To work with long loads made of precast reinforced concrete (up to 12 m), high-rise structures, and pile drivers, tower-boom type equipment is used.

Boom length – 25.8 m (main – 15.8 m). Lattice sections are extended to 30.8 and 35.8 m, which increases the area served by the crane, but reduces the weight of the cargo being handled.

The L-shaped boom head is equipped with a six-meter jib with an installed hook clip of the cable from the 5-ton auxiliary lift winch. A small jib with a length of 2.1 meters can be installed on the boom.

Control

The double operator's cabin is separated from the engine room, where the diesel generator set and control cabinet are mounted. Front and side glazing and lighting provide the necessary overview of the work site.

The cargo lifting winch is switched by a command controller; additional and boom winch, travel unit - magnetic starting switches; rotating device - cam electric controller.

Steering brake control: pedal device - hydraulic cylinder - hydraulic cylinder - braking unit lever.

Basic security systems:

Limiter of the load capacity parameter with an indicator of the effective load at the time of lifting. The system de-energizes the electric motors when attempting to work with a load that has a weight that is unacceptable for the established reach of the boom equipment.
Limiter for boom lift parameter. In cranes with flexible suspension, the booms are mounted in units that prevent tilting.
Lift limiter for the hook device, located in the head part of the boom installation.

When one of the limiters is triggered, the control system unit automatically disables the controlled unit or group of mechanisms.

The system allows operation only by ensuring a decrease in the parameters that caused the limit sensor signal. If the lifting capacity is exceeded, the winch can only be started for lowering.

The boom winch will operate to reduce the reach of the hook device.

Construction of crawler cranes[edit | edit code]

A crawler crane consists of two main parts: a slewing and a fixed crane.

It is a running welded frame connected to two longitudinal beams on which final drives are installed. The crane is turned by slowing down one of the tracks, while the speed of the second one increases. When one track is fully braked, the speed of the second doubles, and the crane rotates around its axis.

The movement mechanisms are made with separate drives of crawler bogies according to several design schemes. The lifting mechanisms have a dual-motor drive with a differential, which gives four speeds.

Drive unit

Cranes with a low lifting capacity are driven by a diesel engine with a mechanical transmission, and with a lifting capacity of more than 16 tons, by a diesel generator set. Cranes with an AC power plant can operate from an external network. In some models of cranes with group drive mechanisms, a turbo transformer is installed in the transmission, which improves the performance characteristics of the crane. However, the scheme with a turbotransformer is quite complex and cannot be implemented using only standard components and parts. The use of an individual drive in this regard has great advantages. Crawler assembly cranes use exclusively an individual drive, and their individual models differ mainly only in the layout of the mechanisms on the turntable.

MKT-40

The MKT crane consists of a rotating section mounted through a full-revolving shoulder strap on a 1-axle platform. The front part of the chassis is equipped with a bracket that is installed on the fifth wheel of the towing vehicle. On the chassis there is a stand necessary for laying the boom when the crane moves along public roads.

The rear axle of the chassis is equipped with a drive that includes an AC electric motor. Electricity comes from a generator, the rotor of which is driven by the tractor’s power unit. A transfer gearbox is used to transmit torque from the motor. The drive is turned on by the driver of the tractor; The mode is only used when driving short distances at a speed of 4.5 km/h.

Description of the dimensions of the MKT-40 crane and technical characteristics:

wheelbase - 6100 mm;
ground clearance - 715 mm;
distance between support axes - 5460 mm;
length in transport condition - no more than 12700 mm;
height - 4000 mm;
engine type - 2-stroke diesel YaMZ;
engine power - 215 hp;
load capacity on/without supports – 40/11 t;
installation weight - 48 tons;
lifting height - up to 15.6 m.

To ensure the stability of the crane, hydraulically controlled outriggers are used. Individual configuration of units is carried out by the driver. The crane chassis has a distribution board that allows it to be connected to an industrial power supply with a voltage of 380 V. A ring contact group is used to transmit current to the rotating platform.

The designation MKT-40 is also assigned to the Ulyanovets automotive hydraulic crane, based on a 3-axle KamAZ, Ford or Volvo chassis (it is possible to use vehicles of other brands). The unit is equipped with a 3-section boom, which is expanded using a hydraulic cylinder and cable drives. To ensure stability, a support contour with dimensions of 5600*5800 mm is used. The chassis and units allow the machine to be operated at temperatures from -40°C to +40°C.

Installation options:

load capacity - 25 t;
boom length (standard version) - 9-30 m;
lifting height (with jib) - up to 30 m;
jib size - 6 or 9 m;
load moment - not less than 120 t*m;
curb weight of the vehicle - 33,000 kg;
speed on the highway is 60 km/h.

The turntable is installed on the chassis through a support ring with a diameter of 1920 mm, equipped with a double rotation mechanism. To ensure cargo performance, a winch with a helical gearbox RK 450 is used. The operator's workplace is equipped with joysticks and an adjustable seat. The cabin is equipped with an autonomous heater; An air conditioner can be installed upon request.

Truck crane "Klintsy" KS-65719-1K (KAMAZ-6540, 8×4) 40t

View in Price

Description of the Klintsy KS-65719-1K truck crane based on KamAZ-6540, with a lifting capacity of 40 tons:

The KS-65719-1K automobile hydraulic crane is mounted on the basis of a KamAZ-6540 highway vehicle with an 8x4 wheel arrangement. The truck crane is intended for loading, unloading, construction and installation work at various construction sites.

Load-bearing metal structures are made of high-quality WELDOX steel. The boom sections are made from bent profiles and, in accordance with modern trends in global crane construction, have a non-rectangular cross-section with a lower chord in the form of an ellipse. The length of the boom in the folded position is 11.2 m, which provides the crane with the necessary maneuverability and compactness when moving. When the sections are folded, the length of the boom is 34.0 m, which ensures a wide working area and the greatest height of cargo movement during operation. The ability to extend the boom with a load allows the crane to perform tasks such as installing loads in hard-to-reach places and moving them among mounted structures. The operating mode with the support beams folded allows for more efficient use of the crane’s capabilities in the densely built-up conditions of modern cities. Thanks to the use of one hydraulic cylinder in the boom telescoping mechanism, it was possible to increase the lifting capacity of the truck crane with large boom lengths.

The lifting mechanism is operated by a hydraulic pump. Smooth control of all mechanisms is ensured using the hydraulic system of the crane. It is possible to simultaneously combine several crane operations.

An additional option is the installation of a lattice jib 9 m long, with the ability to change the angle relative to the longitudinal axis of the boom. The jib will significantly expand the area of use of the crane, the area of its service area and the size of the boom space.

Additional removable counterweights weighing 6 tons can significantly improve the cargo characteristics. Installation of jib and additional counterweights into the working position is carried out without the use of additional lifting equipment and human resources.

The gearboxes of the mechanisms for lifting loads and turning the crane are planetary type with disc brakes, which meets modern requirements for lifting machines. Many crane components use imported components that do not require replacement or repair over the entire service life of the crane. An autonomous diesel heater is used to heat the crane operator's cabin.

Safe operation of the crane can be ensured by a complex of devices and instruments, among which it should be noted a microprocessor load limiter with a digital indication of operating parameters; all data will be displayed on the display in the operator’s cabin. This device automatically protects the crane from tipping over and overloading. The truck crane is equipped with a crane protection system necessary for working in cramped conditions, and a built-in telemetric memory unit (“black box”) and a crane protection module from dangerous voltage (MZON) are installed for working near power lines.

Description of the model KS-65715-1

The KS-65715-1 truck crane with a lifting capacity of 50 tons is mounted on a KAMAZ-65201 chassis (8x4)

The compact telescopic crane KS-65715-1 manufactured by GAKZ JSC based on the serial KAMAZ 65201 chassis, thanks to its long boom, the presence of the longest jib in its class, as well as high lifting capacity, is a worthy alternative in the “taxi crane” class " Maneuverable and road-legal, it is fast and nimble in city traffic and immediately ready for work on the construction site.

Telescopic boom 40 meters long;
Two-section extension 17 m long, installed relative to the boom axis at an angle of 0, 20, 40 degrees; it is possible to work with a boom extension at all boom lengths;
High lifting capacity with full and partial counterweight;
Installation of additional counterweights into the working position is carried out without the use of additional lifting equipment and human resources;
Possibility of telescoping with a load on a hook;
The crane is equipped with a removable winch;
Ease of maintenance of the boom and winches is ensured due to the presence of a convenient platform;
360 degree work area without loss of cargo-height characteristics in the front working area “above the cabin”;
The maximum size of the support contour is 7.5x7.2 meters;
Working on outrigger beams that are not fully extended;
Fuel economy in crane mode is up to 7% thanks to an economical hydraulic drive system;
Bosch-Rexroth hydraulic system, providing smooth control of all mechanisms with a wide range of speed control for working operations;
Thanks to the LUDV system, the possibility of guaranteed combination of several crane operations is realized, regardless of the load on the executive bodies;
The WEBASTO Air Top 2000 ST air heater, installed as standard, guarantees a comfortable temperature in the crane operator’s cabin at any time of the year;
As an additional option, WEBASTO air conditioner or AUGUST air conditioner can be installed;
As an additional option, an additional (second) air heater WEBASTO Air Top 2000 can be installed.

In the manufacture of load-bearing metal structures of the crane installation and the five-section telescopic boom, imported high-strength WELDOX steel is used. The boom sections are made of two bent all-metal profiles and, in accordance with modern trends in global crane construction, have a non-rectangular cross-section with a lower chord in the form of an ellipse. The length of the boom in the retracted position is 10.4 m, which ensures the crane's compactness and maneuverability when moving. When all five sections are fully extended, the length of the boom is 40.0 m, which provides a wide working area and the greatest height of load movement during operation.

The hydraulic system of the KS-65715 truck crane from Bosch Rexroth is built on an innovative solution for the joint operation of the LS + LUDV systems, which ensures the combination of operations in any mode of operation of the crane. In this case, the rotation function always remains a priority, i.e. the slewing speed always corresponds to the value set by the crane operator, regardless of the load. This advantage makes the KS-65715 truck crane more productive compared to standard solutions, and as a result allows you to reduce the cycle time by up to 30%.

Using an adjustable pump with LS+LUDV systems allows you to reduce fuel consumption when operating a crane installation by 20%. This saving is achieved due to the fact that the pump supplies to the working system only the flow rate necessary to ensure the specified operating speeds of the crane. When the crane is idle, the pump reaches its minimum working volume and does not supply working fluid to the hydraulic system, and as a result, the chassis engine is unloaded.

The slewing system is one of the main functions of the crane

It is extremely important that control of this function is as precise, stable and comfortable as possible. When using the Bosch Rexroth swing brake pedal, the operator will be able to control the acceleration, braking and precision of the steering function in any situation. This solution was implemented through the use of an additional braking circuit

Technical parameters and operational features of RDK-400

The load height and technical characteristics of the RDK-400 crane are presented in the table.

Parameter	Characteristic
Load capacity, t	40
Load moment, t×m	172
Minimum reach, m	3,75-24,65
Load lifting height, m	35,6
Lowering depth, m	5

A special feature of the crane installation is its low moving speed – 1 km/h. and rapid wear of caterpillar tracks, which necessitates the use of a special truck tractor with a trailer trailer to deliver special equipment to the construction site. Each movement must be coordinated with the traffic police in order to obtain permission to transport heavy equipment and escort vehicles.

Dimensions of the RDK-400 crane

Why is it convenient to work with cranes?

A crane of this type is indispensable in many cases and helps to quickly resolve various issues.

It allows:

Save energy. With the help of a manipulator you can work with large masses, practically without straining;
To save time. The crane allows you to perform a volume of work during a work shift that would take several days with manual labor.
Save money. The crane is both a lifting equipment and a transport platform.
One person is enough to operate the machine - he is both a driver and a crane operator, and in some cases he can perform the work of a slinger.
Perform tasks in difficult conditions. The crane is compact and has good maneuverability.
Work promptly. Wheeled vehicles can quickly deliver cargo to a construction site.

Important How to make a harrow for a walk-behind tractor with your own hands according to the drawing

Renting a crane will cost less than a truck crane. This is also explained by the fact that the power of vehicles on which crane equipment is installed is less than those that transport large booms with an additional control cabin. Therefore, if the construction does not have a huge scale with the need to move large tonnages, the use of cranes is quite advisable.

Instructions

Preparing the base

The temperature of the base and the environment must be in the range from +5 °C to +30 °C. The base must be dry, strong, thoroughly free of dust, dirt, oil stains, bitumen, residues of organic and mineral adhesives, paints and other substances that can weaken the adhesion of the plaster layer to the base. Before applying the solution, the surface of the base must be moistened, and it is recommended to treat uneven or highly absorbent surfaces (foam concrete, aerated concrete, old brickwork) with a deep penetration primer EK GS300 DEEP, EK GS300 TIEFENGRUND or EK GS400 ANTISEPTIC in one layer, and unevenly or highly absorbent surfaces (foam concrete, aerated concrete, old brickwork) in two layers.

Preparation of the solution

To prepare the EK TG40 solution you need:

Take a precisely measured amount of water (12-15 liters per 30 kg bag)
Pour the mixture into water
Mix using a construction mixer or a drill with a special attachment until a homogeneous mass is obtained.
Maintain a technological pause of 5-10 minutes for the solution to mature
Stir again

After this, the plaster is ready for use within 90 minutes with occasional stirring

Work order

The plaster is applied to the base and leveled using the rule. The recommended thickness of the plaster layer applied in one pass is from 5 to 50 mm. After the setting begins, lightly moisten the plastered surface, rub it with a sponge trowel and smooth it with a metal float. If it is necessary to plaster in several layers on the surface of the first layer that has not yet hardened, it is recommended to make a notch with a plaster comb or a notched trowel, and then apply a second layer of plaster to the dried surface (but not earlier than a day later).

The procedure for carrying out the technological cycle

Advantages of CMU

Using a vehicle with a CMU is more profitable and simpler than using a separate truck and a separate crane. Pure mathematics: two vehicles cost more than one. A vehicle with a crane has other advantages:

Mobility. Special equipment, especially its compact types, moves freely around the city.
Reliability. When properly controlled, a vehicle with a CMU operates reliably and copes with many tasks.
Multitasking. Special equipment is capable of performing many different tasks needed for construction and other industries.
