Chain hoist is a kind of easy-to-use and easy-to-carry manual lifting machine, suitable for use in factories, mines, construction sites, agricultural production, docks, docks, warehouses, etc. for installing machinery, lifting goods and loading and unloading vehicles, especially for outdoor and No power operation, it has its important function.

    The chain hoist adopts a symmetrically arranged two-stage spur gear transmission structure. The operator should stand in the same plane as the hand sprocket and drag the hand chain, and rotate the hand sprocket clockwise to raise the weight. Pull the hand chain in the opposite direction. The heavy object can slowly fall.

   The chain hoist is the same as the lever hoist's labor-saving principle, and is implemented by a differential pulley; the difference is that the chain hoist is driven by a hand zipper bar, which is mostly used to lift heavy objects vertically; the lever hoist is carried by a handle. Drive, mostly used to move heavy objects horizontally.
