The lifting and pulling distance of this hoist is not limited and can be determined by the length of the chain selected. Hand-operated chain hoists are widely used in shipyard assembly and welding, joint tightening of high-voltage transmission lines in the power sector, lifting and loading trucks, material bundling, vehicle pulling in the agriculture, forestry, and transportation sectors, and equipment installation and calibration in factories and other departments.

In addition, the lever hoist is also called a manual lifting tool. It can also be used for lifting, pulling, lowering, calibration and other operations. The lifting capacity generally does not exceed 50T. It has the characteristics of safety, reliability, durability, good performance, easy maintenance, small size, light weight, easy to carry, small hand force, high efficiency, perfect structure and beautiful appearance.
