1. The amount of energy saving of the pulley set is determined by the number of rope strands, the total weight of the weight and the pulley is borne by n strands of rope, and the force used to lift the weight is 1/n of the total weight.

2. In use, the amount of labor saving and rope winding, depends on the use of the pulley set.

3. The mechanical efficiency of the pulley block is determined by the gravity of the pulled object, the gravity of the pulley and the friction.

4. The pulley block is roughly divided into: hook type mixing block, ring type pulley block, hanging bar type pulley block, you can choose the specific configuration according to the actual application on site.
