Do you know the composition of Crawler Crane?

Crawler Crane is a mobile boom crane with a crawler running device. It consists of metal structures such as boom, turntable, lifting, rotating, luffing and running mechanism. The hoisting and luffing mechanism adopts a reel to wind the steel rope, and the lifting device is lifted and the boom is pitched and luffed by a compound pulley. The rotating mechanism adopts a turntable support device. The mechanism has two driving methods: ① Centralized driving. Pass the power of the internal combustion engine through the fluid coupling and the power distribution box, and then manipulate the clutch to move each mechanism. ② Drive separately. An internal combustion engine and a generator set are used to move the power through various motors and transmissions to move the mechanism. For industrial and forestry lifting and loading operations.

Crawler Crane China can perform material lifting, transportation, loading and unloading operations. The crawler crane has the advantages of strong lifting capacity, low ground pressure, small turning radius, large climbing ability, no legs, driving with load, good operation stability, and freely replaceable truss combination height. Construction industries such as bridges, petrochemicals, and water conservancy and hydropower are widely used.

Crawler Crane

A crawler crane is a hoisting machine used for lifting and hoisting on a crawler. It is the most widely used crane for single-story industrial workshops. It consists of a power unit (engine), transmission unit (main clutch, reducer, reversing mechanism, etc.), slewing mechanism, running mechanism (track, walking bracket), hoisting mechanism (hook and boom lifting mechanism), operating system, It consists of working equipment (suspender, lifting pulley group, etc.) and electrical equipment.

composition

The crawler crane consists of a power unit, a working mechanism, a boom, a turntable, and a chassis.

Boom

It is a multi-section assembled truss structure. The length can be changed after adjusting the number of nodes. The lower end is hinged at the front of the turntable. The top end is suspended and supported by a luffing wire rope pulley unit to change its inclination.

There is also a jib installed at the top of the boom, and the jib makes a certain angle with the boom. The lifting mechanism has two main and auxiliary hoisting systems. The main hoisting system is used for boom lifting, and the sub hoisting system is used for lifting jib.

Turntable

The slewing bearing is mounted on the chassis and the entire weight of the turntable can be transmitted to the chassis, which is equipped with a power unit, a transmission system, a hoist, a control mechanism, a counterweight, and a shed. The power unit can make the turntable turn 360 ° through the turning mechanism. The slewing support is composed of upper and lower rollers and rolling elements (balls, rollers) in between, which can transfer the entire weight of the turntable to the chassis and ensure the free rotation of the turntable.

Chassis

It includes a walking mechanism and a walking device: the former makes the crane move forward and backward and turn left and right; the latter consists of a track frame, a driving wheel, a guide wheel, a track roller, a supporting chain wheel and a track wheel. The power unit rotates the driving wheels through vertical axis, horizontal axis and chain transmission, so as to drive the guide wheel and the supporting wheel, so that the whole machine rolls along the track and walks.
