Definition of the lever hoist

The chain block is a clamp body that manually pulls the handle with the help of lever principle to obtain the linear traction matching the load, and acts on the load in the movement core in turn to drive the load operation. The utility model has the advantages of compact structure, light weight, small overall dimension, convenient and labor-saving carrying, safety and reliability, long service life, small wrench force, small abrasion of steel wire rope, etc. It can carry out lifting, traction, lowering, calibration and other operations. If equipped with special devices, not only can the non-linear traction work be done, but also the suitable operation position can be conveniently selected, or the load capacity can be multiplied by the smaller tonnage machines and tools. For the larger tonnage load, several machines and tools can be used for parallel operation.
