GM-3 friction lining

As one of the main components of friction lining for multi rope friction hoist, early applied to multi rope friction hoist. friction lining are mainly polyvinyl chloride (PVC) and polyurethane (CPUR), polyvinyl chloride (PVC) friction liner friction coefficient (0.20) and wear resistance are poor, polyurethane (CPUR) frictionlining increase in wear resistance, but the friction coefficient is still in 0.2-0.23, and because of poor processing performance, Rope groove was difficult, because of the process factors of rope groove, so that the quality is not stable. melting phenomenon will cone in the using, therefore, polyurethane (CPUR) friction lining also can be used only in the range of friction the coefficient of 0.22. In our country, multi rope friction hoist of friction coefficient of more than 0.25 is imported from abroad, but the price is expensive and the import cycle is long. 

High friction liner is divided into domestic high friction, imported materials to suppress high friction, pure imported high friction three. The users can choose at will according to their needs. Tower hoist liner is a rope groove, floor type hoist liner two rope grooves, mainly for the convenience of turning rope groove. In return, they also improved the liner service life and the usage rate of liner material. The friction liner is fixed on the friction wheel by fixed block and pressing block through bolts.
