In the process of working with the round chain block, the upgraded version of the fixed pulley completely inherits the advantages of the fixed pulley to a certain extent. In operation, the combination of the reducer and the chain pulley block with reverse reverse braking is arranged symmetrically. The secondary spur gear rotation structure is simple, durable and efficient.
The round chain hoist can effectively rotate the manual chain and the hand wheel when the wheel is rotated, and the friction plate ratchet and the brake seat are pressed together to rotate together, and the long shaft of the tooth rotates the plate gear, the short shaft of the tooth and the spline hole gear. Thus, the hoisting sprocket of the device on the spline hole gear drives the hoisting chain to smoothly lift the weight. The ratchet friction plate type one-way brake can brake itself under load, and the pawl meshes with the ratchet under the action of the spring, and the brake works safely.
Round application chain hoist application range
Hand chain hoists are mainly used in factories, mines, construction sites, docks, docks, warehouses, etc., for installing machines and lifting goods, especially for open-air and power-free operations.
