Chain block is suitable for short-distance lifting of small equipment and goods, with a lifting capacity generally not exceeding 10T, and a maximum of 20T. The lifting height is generally not exceeding 6m. The outer shell of the hand chain hoist is made of high-quality alloy steel, which is sturdy, wear-resistant, and has high safety performance. When lifting heavy objects, the manual chain is pulled clockwise to rotate the hand chain wheel. When lowering, the manual chain is pulled counterclockwise, the brake seat separates from the brake pads, and the ratchet stops under the action of the pawl. The five-tooth long shaft drives the lifting chain wheel to run in the opposite direction, thus smoothly lowering the heavy object. The hand chain hoist generally uses a ratchet friction plate type one-way brake, which can brake itself under load. The pawl engages with the ratchet under the action of the spring, making the brake work safely.

It features safety and reliability, simple maintenance, high mechanical efficiency, low chain tension, light weight for easy carrying, beautiful appearance and small size, and durability. It is suitable for factories, mines, construction sites, docks, shipyards, warehouses, etc., for installing machinery and lifting goods. It is especially advantageous for open-air and power-free operations.
