The working conditions of the track are harsh, with sufficient strength and stiffness, good wear resistance requirements, light weight to reduce metal consumption, and reduce the dynamic load during track operation. The track and ground should have good adhesion performance to ensure sufficient traction, and also consider reducing driving and turning resistance.

The buffer spring of the tensioning device has a certain amount of preload, which generates pre tension force in the track. Its function is to not be affected by slight external forces when moving forward, and to generate sufficient traction to ensure the normal meshing of the track pin and the driving gear teeth.

Due to the recoil effect of the device, the tensioning spring is pressed against the guide wheel on the right side to maintain a certain tension state during operation, thereby guiding the track tensioning guide wheel.
