The material of pulley is generally HT15-33 cast iron, and ZG35Ⅱ cast steel is often used for grab buckets and cranes for special purposes. In order to improve the efficiency of the pulley block and improve the conditions of use, the bearings of the pulley are all rolling bearings.
Pulley rope groove:
When selecting the pulley rope groove, the radius of the rope groove is often taken as R=0.6d, and the contact surface between the wire rope and the rope groove is required to be as large as possible.
