The material selection of the anti sinking track chassis is reasonable, and it is made of alloy steel and quenched to improve the wear resistance of the guide wheel and drive wheel teeth, thereby prolonging the service life. The spring tensioning mechanism is equipped with a color screw adjustment, which has high reliability and is a multi section assembled truss structure. After adjusting the number of sections, the length can be changed. 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 group, which can change its inclination angle.

For the slewing bearing installed on the chassis, it can transfer all the weight on the turntable to the chassis, which is equipped with power devices, transmission systems, winches, control mechanisms, counterweights, and sheds. The power device can rotate the turntable 360 ° through a rotating mechanism. The slewing support consists of upper and lower rolling discs and rolling elements between them, which can transfer all the weight on the turntable to the chassis and ensure the rotation of the turntable.
