TYPE:SN-WFQS

WFQS full-plastic flex fire-retardant balance compensating chain, is a kind of product with good function to keep elevator smooth operation. In structure, it is a perfect combination by welding chain and synthetic PVC,  and formed special character.   

The advantage is of good flexibility, low noise, small curvation radius, fire retardant, ageing-resistant, keep the elevator operating smoothly, and can be used in the temperature of -15~+60 degree centigrade, the elevator speed lower than 2.5m/s.

Note: In order to ensure the compensating chain run safely and smoothly, we suggest using dampening device and hanging device provided by us.
