Hoist head sheave liner and guide pulley liner
Friction liner material experienced the process of polyvinyl chloride, polyurethane, polyurethane, and thermosetting materials.
The first three materials designed the friction coefficient in 0.2 ~ 0.23, the last material’s friction coefficient is more than 0.25 ( high friction liner). 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 blo |
