Background

The coal pusher is a large-scale engineering vehicle specially used for coal yard operation, is mainly used for operations such as bottom coal piling and the like, is a homologous engineering machine of a crawler type bulldozer, and has a similar appearance to the bulldozer. As the coal pusher frequently climbs a coal pile, shovels coal, pushes coal and the like in the coal yard operation and needs larger traction force, the crawler belt is in the form of a single-bar steel crawler plate. Different from a three-rib type track shoe commonly used by an excavator, the single-rib track shoe is characterized in that the single rib has larger protruding height, and the single rib is deeper cut into a coal pile during advancing, so that larger advancing traction force can be obtained.

After the closed coal yard is transformed, the coal pusher needs to turn over and push in the transition between the coal yards, and the coal pusher needs to travel through a cement concrete road in a factory area during the transition. However, when the single-rib type crawler runs on a hard road surface, the coal pusher has large mass, so that the single rib has large pressure on the ground, and the road surface is easily damaged to cause irreparable damage, so that the single-rib type crawler cannot directly go on the road, and needs to be transported by a flat car to assist in transferring, thereby bringing high transferring cost.
