Description

Story

In 1965, the Dnepropetrovsk Experimental Plant of Mechanization Equipment

began production of crawler cranes model
MKG-25
on a running gear with multi-roller crawler bogies. The crane was equipped with an individual drive and had a lifting capacity of 25 tons. A 17.5 m long boom was installed as the main boom equipment. The main boom was extended using replaceable insert sections, each 5 m long, which made it possible to increase the boom length to 32.5 m.

All main components of the MKG-25

, in addition to the running gear, they are unified with a crane on pneumatic wheels
MKP-25
, which was produced by
the Kuibyshev Mechanical Plant No. 1
and was distinguished by a reduced lifting capacity on an auxiliary hoist of up to 3 tons.

Important TOP 6 forklifts of the Dalian model range and their technical characteristics

In 1966, based on the MKG-25

RDK-25
was created , and in 1972 the production of its modification, the RDK 250-1 crane, began.

In June 1967, the MKG-25BS

, created in the Central Design Bureau of Glavstroymekhanizatsiya of the Ministry of Assembly and Special Construction of the USSR using the undercarriage components of
the MKG-25
.
In the jib version, the technical characteristics of the cranes were the same, however, the new MKG-25BS
could be retrofitted with tower-jib equipment.

Cranes MKG-25BS

were intended: in the boom version - to perform installation work on the construction of industrial facilities, and in the tower-boom version they were used for the installation of long (up to 12 m) reinforced concrete slabs and headframes in coal mines.
The first batch of these cranes was produced in the first quarter of 1968 at the Dnepropetrovsk Metal Structures Plant No. 2
.

Description MKG-25BR

The crane is intended for installation, loading and unloading operations, and is also used in bridge construction, and has also been used in energy construction. The crane is a modification of the MKG-25

. Produced at the Chebarkul Mechanical Repair Plant.

The MKG-100 crane with a lifting capacity of 100 tons with an individual electric drive is mounted on a running gear with multi-roller crawler bogies with six support rollers. The rotary support is a double-row ball bearing. The main working equipment is a boom with a jib. The set of replaceable working equipment includes boom equipment with extended booms and jib and tower-boom equipment. The electric motors of the mechanisms are powered by an alternating current voltage of 380 V and a frequency of 50 Hz from a diesel-electric installation or from an external network. The diesel-electric installation consists of a YaMZ-236 diesel engine and an SGD-100-4 generator with a power of 100 kW. The main winch, like that of the MKG-16, MKG-25 and MKP-25 cranes, is two-speed with a differential, but the small engine rotates the drum not through a single-stage cylindrical gearbox, but through a two-stage helical-bevel gearbox. The auxiliary winch is unified with the cargo winch. The kinematic diagram of the crane has two identical rotation mechanisms installed in the front part of the platform under the heel of the boom. The movement of the tracked vehicles is transmitted from one engine through planetary gearboxes, cardan shafts and final drives. The input shafts of the final drives are connected to each other by cardan shafts. The mechanisms are controlled electrically. The electrical circuit diagram of the mechanism drive is unified with the electrical circuit diagrams of the MKG series cranes. The crane is equipped with limiters for lifting capacity, maximum load, lifting height of hook hangers, tilt angles of the boom and jib of tower-boom equipment, as well as indicators for outreach of boom and tower-boom equipment.

Crane ugs 100 technical specifications

The MKGS-100 crane is a jib assembly crawler crane with a lifting capacity of 100 tons, designed for the installation of heavy and large-scale equipment, building structures, as well as reconstruction of enterprises in various industries, including metallurgical and petrochemical.

The design of the MKGS-100 crane includes the running and slewing parts, boom and turret-boom equipment, winch, hook cages, diesel-electric unit, rotation mechanism, mounting stand, generator group and slewing bearing cabin. All operating mechanisms of the crane are powered by a direct current electric drive. This ensures low landing speeds and helps them regulate speed from zero to maximum.

The design of the crane was developed by specialists from VKTI Minmontazhspetsstroy and the design bureau of the Ulyanovsk Mechanical Plant No. 2. The same plant launched the production of these cranes (the MKGS-100 crane - since 1978; the MKGS-100.1 crane - since 1990).

A special feature of the MKGS-100 crane is increased mobility due to the use of a new transportation scheme. The rotating part of the crane rests on the frame of a two-axle pneumatic wheeled trolley, which is connected to the lower frame of the crane using a bracket, and the supporting part of the boom is connected to the saddles by a tractor unit. In this way, a road train weighing about 56 tons is created, which ensures its free movement in the traffic flow on the roads.

The MKGS-100 crane is equipped with elongated booms due to 7 m inserts. All booms can be equipped with an uncontrolled jib 12 m long. Tower-jib equipment is provided: towers 29, 43 and 50 m long and steerable jib 19 - 40 m long. The crane is equipped with a device for increasing the lifting capacity due to an additional mast and a suspended counterweight up to 160 tons. The crane is transported on roads in enlarged units: a rotating part and a lower frame, boom sections of 14 and 7 m, crawler bogies, a counterweight. By rail, the crane is transported on 5 platforms instead of 14 with the usual disaggregation into assembly units.

Crane MKGS-100 technical characteristics

— Maximum lifting capacity 100 tons — Basic boom length 22 m — Maximum boom length 57 m — Undercarriage width 7000 mm — Length 9100 mm — Height 4250 mm — Rated motor power 100 kW

Transporting the crane requires special transport equipment. When transported by road using a truck tractor, the crane structure is disassembled into components, and when transported by rail, sections of the tower-boom equipment are stacked on top of each other without disassembling the crane along the slewing bearing. The original principle of modular construction gives the MKGS-100 an advantage over other heavy-duty cranes associated with the dismantling and transportation of equipment of extreme dimensions.

MKGS-100

All crane systems are supplied with energy from an electric drive. The equipment has been produced by the Ulyanovsk Mechanical Plant since 1978. Using the device, mid-rise buildings are erected. The unit carries out the installation of heavy large-block equipment during the construction of structures or reconstruction of facilities.

The body is made of durable steel, which increases the service life of the product. The main structural elements are: tracks, running and rotating platform, stand, rotation mechanism, winch, diesel-electric engine, generator, turret-boom unit, cabin, hook.

The MKGS-100 crawler crane, the technical characteristics of which are discussed below, has increased mobility thanks to a new method of transportation. The turning mechanism rests on the trolley frame with 2 axles. This frame is connected to the lower frame by means of a bracket. The boom support interacts with the tractor. This creates a road train weighing 56 tons, which allows it to move.

The unit has an elongated boom due to sections of 7 m. A jib 12 m long can be placed on the boom. The boom assembly consists of a tower of some length and a controlled jib. The machine is equipped with an additional mast and counterweight, which increases the load-carrying capacity of the structure.

Technical characteristics of the MKGS-100 crane:

Loading capacity is 100 tons.
The width of the undercarriage is 7000 m.
Parameters: length - 9100 m, height - 4250 m.
The maximum boom length is 57 m.
Motor power - 100 kW.

The unit is transported using a special mechanism. The device is transported on roads by a tractor-trailer, and the device is disassembled into separate units. When moving by rail, individual sections of the device are stacked on top of each other.

Advantages

This type of crane has a number of technical and functional advantages that distinguish the equipment from analog versions of equipment from other companies:

adapted for road transportation - available special equipment allows you to partially disassemble the crane and deliver it to its destination;
the structure of the device is capable of being folded into fairly maneuverable dimensions - thanks to the sectional folding of the boom unit;
higher possibility of boom ejection - the height of the tower is 10-15% higher than analog models, which significantly increases the scope of application of the equipment and increases its functionality;
high level of mass of lifted loads - this is possible even with the maximum ejection of tower equipment;
the crane boom is lifted autonomously using special mechanisms;
the presence of a diesel-electric drive is an additional possibility of deeply adjusting the speed mode of operation of the vehicle and ensuring low landing speeds;
high frost resistance characteristics - this criterion is especially important for many Russian regions with difficult climatic conditions and low temperature differences. The permissible temperature required for its uninterrupted operation varies in the range from +40 to –40 degrees;
microprocessor lifting clamps - this complete set guarantees absolute safety of the equipment and the scope of work across the entire range of load indicators of the unit;
mobility and autonomy of movement - tracked vehicles of this model are capable of independently moving within construction areas without additional tonnage from any tower-boom configuration, as well as with a small load on the main lifting boom.

Design Features

The vehicle is equipped with a drive mechanism powered by DC electrical voltage. This gives a certain smoothness when operating the equipment.

In addition, the crane is designed using an aggregate construction method , which greatly simplifies the operator’s work during the dismantling of buildings and structures, as well as when transporting components, in comparison with analog models of the heavy-duty equipment class.

The unique equipment made it possible to transport the crane along highways and highways using saddle equipment. Its main components are easily dismantled.

When traveling by rail, the slewing bearing unit is not removed, and all parts of the boom structure are folded telescopically. At the same time, their maximum lifting is performed autonomously - by the forces of the model mechanism.

Self-propelled equipment can operate both from its own unit (powered by diesel fuel) and from three-phase voltage. The diesel power source is a separate unit and is not installed on the crane.

MGKS has several modifications depending on the height of the boom throw and the carrying capacity.

All design features of the modified version of the MKGS line are aimed at improving functional, operational and technical characteristics, which fully correspond to the indicators declared by the manufacturer.

Crawler crane MKG-25 - application and advantages

Distinctive features of the MKG-25 crane design:

Chassis. The trolleys with caterpillar tracks are sliding and are supported by a welded frame. The track width varies from 2.57 to 3.67 m - this gives strength when lifting heavy weights.
The turntable is mounted on a load-bearing frame. All working components of the crane lifting mechanism are located on the platform.
Crane equipment. The MKG-25 boom is of short length, which allows work in a room with ceilings = 8 m, the jib attachment is rigid.
The crane operator's cabin with panoramic glazing is located on a turntable. The actions of the boom and lifting mechanisms are coordinated using switches, while the rest of the equipment is controlled by controllers.
Electrical equipment. The MKG is equipped with an independent type DU-50 diesel power plant, from which all working components of the crane are powered. If you have a standard power line, you can connect to it using flexible hose cables and ring current collectors.

Several electric drive motors allow the crane operator to control the lifting and lowering of loads. Lifting the load has 2 speeds, and lowering has 3, one of which is “landing”.

Power point. The crane is equipped with a diesel engine whose power = 50 kW. The high-speed winch operates using a motor and a planetary gearbox.
Operational safety. All units responsible for lifting and lowering loads and booms have command controllers. The angles of rotation of the platform are also controlled and limited.

Due to their design features, MKG-25 cranes have advantages:

ease, reliability in operation and maintenance;
work on unprepared sites;
diesel - electric crane saves fuel;
tower and boom design;
there are no complex waterworks.
