The pulley block is a simple machine assembled by a plurality of moving pulleys and fixed pulleys, which can not only save labor, but also change the direction of force. The labor saving of the pulley block is determined by the number of rope strands, and its mechanical efficiency is determined by the gravity of the pulled object, the gravity of the moving pulley and friction. The pulley block is mainly applicable to qd5 ~ 200t electric double beam bridge crane, gantry crane and hook group.

The pulley block is mainly applicable to qd5 ~ 200t electric double beam bridge crane, gantry crane and hook group.
Use of pulley block: pulley block is widely used in cranes, hoists, elevators and other machinery. It is an important part of hoisting machinery.
Characteristics of moving pulley, fixed pulley and pulley block:
The fixed pulley can change the direction of the force, but it can't pull the object easily.
The moving pulley can not change the direction of the force, but can pull the object very easily.
The pulley block combines a fixed pulley and a moving pulley, which can not only change the direction of the force, but also pull the object with less effort. The more moving pulleys in the pulley block, the less labor
The material of pulley block is divided into gray iron pulley, cast steel pulley and rolling pulley.
Pulley block model: 5T gray iron / cast steel / rolling pulley block, 10t gray iron / cast steel / rolling pulley block, 16t gray iron / cast steel / rolling pulley block, 20t gray iron / cast steel / rolling pulley block, 32t gray iron / cast steel / rolling pulley block, 50t gray iron / cast steel / rolling pulley block, 80t cast steel / rolling pulley block, 100t cast steel / rolling pulley block.
