The hoisting Sheave inserts is mainly to prevent the wear between hoisting sheave and to direct with each other. The hoisting Sheave inserts plays a very important role in protect the service life of cause rotation during the operation. If the friction coefficient is too high, the rotation of the be hindered to cause the damage to the this situation, the be led into the shaft by resistance as small as possible to reduce the torque and rotation stress.
For the above requirements, our company carried out a of experiments and finally selected a new material - KP-09 ultra-high polymer. It has superior performance, greatly reducing the damage to the rope and effectively extending the service life of is the most ideal choice for the hoisting sheave pad. Our company can produce products with different shapes and different specifications according to user requirements, and can maintain the exnt performance of ultra-high molecular materials.
