The operation mode of the chain block is more diversified than that of the chain block. Because it uses the method of pulling the handle, no matter whether it is used horizontally, diagonally or vertically, it will not affect its performance. The driving mode of the chain block's chain bar leads to that it can only be used vertically in most cases to ensure that the chain will not break away from the sprocket.

So the chain hoist can not only be used as a traditional lifting tool, but also be used for traction, binding, tightening, etc. Traction, binding and tightening are mostly horizontal or oblique operations. It is the unique skill of the chain hoist to use the reverse braking system to tighten the rope bit by bit.

With such characteristics, the hand lever gourd has room to play in all work occasions, which is the uniqueness of the hand lever gourd.
