To assemble a truss structure with multiple sections, the length can be changed after adjusting the number of sections. The lower end is hinged at the front of the turntable, and the top is suspended and supported by a variable amplitude steel wire rope pulley block, which can change its inclination angle.

The crawler crane is composed of a power device, a working mechanism, a boom, a turntable, a chassis, etc.
Boom
To assemble a truss structure with multiple sections, the length can be changed after adjusting the number of sections. The lower end is hinged at the front of the turntable, and the top is suspended and supported by a variable amplitude steel wire rope pulley block, which can change its inclination angle.
There are also cases where auxiliary arms are installed at the top of the boom, forming a certain angle between the auxiliary arm and the boom. The lifting mechanism has two main and auxiliary winch systems, the main winch system is used for boom lifting, and the auxiliary winch system is used for boom lifting.
Turntable
The slewing support is installed on the chassis, which can transfer all the weight on the turntable to the chassis. It is equipped with power device, transmission system, winch, control mechanism, balance weight, shed, etc. The power device can rotate the turntable 360 ° through a rotating mechanism. The slewing bearing is composed of upper and lower rolling discs and rolling elements (balls, rollers) between them, which can transfer all the weight on the turntable to the chassis and ensure the free rotation of the turntable.
chassis
Including a walking mechanism and a walking device: the former enables the crane to move forward and backward and turn left and right; The latter consists of a track frame, drive wheels, guide wheels, supporting wheels, carrier rollers, and track wheels. The power device rotates the drive wheel through vertical axis, horizontal axis, and chain transmission, thereby driving the guide wheel and support wheel, causing the entire machine to roll and walk along the track.
