链

Performance: 1.PVC-coated compensating chain is made of best welding chain, and the surface plated or anti-rust treated, is wrapped by synthetic PVC, and then processed by special techniques. 2.It has below strong trait, such as: flexibility, fire-resist, wear-resist, small curve radius, and wider temperature adaption range, etc. 3.It can be used for the elevator with rated speed below and equal to 1.75m/s, and also widely used for view-looking elevator.
