The three-track car is changed from the original track side force structure to the bottom force structure, and a roller is designed at the bottom of the three-track car, so that the side track is no longer subjected to force. The three-track car completely relies on the bottom roller to achieve forward propulsion. The workpiece and the trolley are directly placed on the roller of the trolley, so the horizontal operation and sliding are natural.
