Friction line transmission is divided into light load friction line and heavy load friction line, friction transmission line with simple structure, cost-effective, stable operation, easy maintenance, energy saving, low noise and no oil and other advantages have become a new generation of mechanized transportation equipment.

 At present, in the automobile production line, the main application range of friction line is: welding body in white to the painting workshop transport and storage (hereinafter referred to as welding PBS line), coating pre-treatment line, painting PVC line, painting wax spray line, painting to the final assembly of painted body transport and storage line (hereinafter referred to as the final assembly WBS line); Assembly chassis assembly line; Door distribution line, etc.

 Friction transmission lines are mainly divided into two categories from the structure type, which are ground friction lines and air suspended friction lines.

 The friction line is mainly composed of track, switch, friction driving device, stop device, positioning device, vehicle group, detection device, stop device, positioning device, vehicle group, detection device, gas circuit system and electronic control system. According to the different transmission requirements of the production process of the automobile production line, different types of friction lines are adopted.

 The company independently developed the maximum load capacity of heavy-duty self-climbing friction drive is 3,500kg, and the maximum climbing Angle can reach 20°, which can greatly reduce the height of the plant and the cost of construction.
