TL series steel cable drag chains are mainly consisting of chain plate (top quality stainless steel with chromium plated), supporting board (extruded aluminum alloy) and pin shaft (alloy) ect. There is no relative motion between the cable/rubber hoses and the drag chains, giving no deforming or twists. The chromium plated chain board has very nice looking appearance and has very rational construction and flexible and high strength. It is reliable and easy to operate, install, dismantal or assemble. It is worthwhile mentioning that the anti-wearing performance has been improved greatly due to wear resistant material and alloy pin shaft are used. The produce is flexible to bending and has low resistance, giving low noise. It can be used for a very long period of time without any deformation or hanging down.
