Lifting machinery is a lifting and transportation equipment that reduces heavy physical labor, improves work efficiency, and realizes safe production. In the production and circulation of materials in various sectors of the national economy, chain hoists are widely used as a key process design or important auxiliary machinery. A complete action cycle generally includes picking, lifting, translation, unloading, and then returning to the original place. Frequent starting, braking, forward and reverse movement are the basic characteristics of hoisting machinery chain hoists. The chain hoist pulls the manual chain and the hand sprocket to rotate, and presses the friction plate ratchet and the brake seat into one unit to rotate. The toothless long shaft rotates the piece gear, the tooth short shaft and the spline hole gear to drive the lifting sprocket. The lifting chain drives the lifting chain to lift heavy objects. The chain hoist is used for hoisting a lifting weight of about 0.5 tons, using a set of II-level gear reduction transmission. The chain hoist is mainly used in factories, mines, construction sites, wharfs, docks, warehouses or construction occasions without electricity , The driving force is driven manually by hand, which reduces the hand force and increases the gear meshing transmission ratio, making the structure compact and beautiful, economical and durable. Hoisting machinery is a kind of handling machinery that lifts, lowers and moves materials in an intermittent manner. The operation of lifting machinery is usually repetitive. A complete action cycle generally includes picking, lifting, translation, unloading, and then returning to the original place. Frequent starting, braking, forward and reverse movement are the basic characteristics of hoisting machinery chain hoists.
