Pulley
1. Application range: electric hoist and overhead cranes and Gantry cranes
2. It’s simply constituted by some fixed pulleys and movable pulleys.
3. It’s widely used in cranes, winches and elevators.
For light and medium duty overhead crane, its pulley could be cast by gray cast iron HT15-33 and ductile iron QT-10; for heavy duty overhead crane, the material could be cast steel ZG25 or ZG35; and for big-diameter (D＞800mm) pulley, it could be welded by carbon steel Q235-A.

Overview of crane pulley block:
It is the fixed pulley that condole hook group cooperates the job, fixed go up in the structure, by combination of a few fixed pulley and movable pulley and become, it can save force to be able to change force action direction again already.
Classification of pulley:
crane Pulley can divide into working pulley and balance pulley, it is the commonly used machinery that can revolve around central axis.
crane Pulley material:
Pulley HT15 33 cast iron, commonly used materials for grab crane and special purpose often adopt ZG35 Ⅱ cast steel.In order to improve the efficiency of pulley block and improve the service conditions, roller bearings are used for crane pulley bearings.
crane Pulley rope groove:
When selecting pulley groove, the radius of groove is usually R=0.6d, and the contact surface between wire rope and groove is required to be as large as possible.
Use of pulley block:
crane Pulley block is widely used in electric double-beam crane,overhead crane，gantry crane, electric hoist, hoist and other crane equipment, is an important part of lifting machinery.
