Sep 27, 2018

Crane pulley block effectively improves the Angle between the lifting steel wire rope and the service life of pulley and steel wire rope.


Crane pulley block

起重机滑轮组

Structure of crane pulley block:


Including pulley frame, supporting shaft, pulley assembly, pulley shaft, pulley frame rotation of the swing around the supporting shaft;


The pulley assembly is fixed on the pulley block through the pulley shaft.

A pulley bracket is fixed on a fixed support by a supporting shaft.


With the above structure, the pulley frame is integrated on the pulley assembly, which makes the whole machine structure more compact and can effectively improve the Angle between the lifting steel wire rope.


The pulley assembly consists of 1 fixed pulley which is set on the pulley shaft.

The pulley bracket is parallel to the fixed central axis of the pulley in the pulley assembly to control the deflection of the wire rope.


The supporting shaft is installed on the fixed bracket through the pin shaft. The above structure is adopted to make the structure more compact and the supporting shaft is fixed more firmly.


Structural advantages of crane pulley block:


The pulley rack is integrated on the pulley assembly to make the whole machine more compact, which can effectively improve the Angle between the lifting steel wire rope and the service life of the pulley and the steel wire rope.
