When the chain hoist lifts a heavy object, pull the hand chain and hand chain wheel clockwise to rotate, and pull the hand zipper bar counterclockwise when descending. The brake seat is separated from the brake pad. The ratchet wheel is stationary under the action of the pawl. The five-tooth long shaft Drive the hoisting sprocket to run in the opposite direction, so as to lower the weight smoothly. The chain hoist generally uses a ratchet friction plate one-way brake, which can brake by itself under load, and the pawl meshes with the ratchet wheel under the action of the spring to make the brake work safely.
It has the characteristics of safety and reliability, easy maintenance, high mechanical efficiency, small pull force of the bracelet, light weight, easy to carry, beautiful appearance, small size, and durability. It is suitable for factories, mines, construction sites, docks, docks, warehouses, etc. Installing machines and lifting goods, especially for open-air and no power operations, shows its superiority.
The main parts of the chain hoist are made of alloy steel. The chain is made of 800Mpa high-strength lifting chain. The material is generally 20M2. The chain is medium-frequency quenching heat treatment, low wear and corrosion resistance; high-strength hook, the material is generally alloy steel, forged The striking hook design ensures slow lifting to prevent overload; it complies with European CE safety standards.
