Supporting wheels play a crucial role in tracked construction machinery, and their functions and installation methods are detailed as follows: 1. The role of supporting wheels in supporting weight: The main function of supporting wheels is to support the weight of heavy machinery, such as excavators, bulldozers, etc. It ensures that the machinery can travel smoothly on the tracks and withstand the weight from the machinery itself as well as various dynamic loads during operation. Guiding track: The supporting wheels also play a role in guiding the track. It enables the track to move along a predetermined trajectory, preventing lateral slippage or deviation from the track, thereby ensuring the stability and safety of the machinery during operation.

Transmission of power: During the operation of machinery, the friction between the supporting wheels and the tracks helps to transmit power, enabling the machinery to overcome various obstacles and move forward smoothly.

Protecting the track: The support wheels can evenly distribute the pressure of mechanical weight on the track, reduce excessive wear on the track locally, and thus extend the service life of the track.
