The round chain hoist is used as an upgraded fixed pulley when it is used. It fully inherits the advantages of the fixed pulley to a certain extent. In use, the combination of the reverse brake and the chain pulley block are used in a symmetric arrangement. The secondary spur gear rotation structure is simple, durable and efficient.
The circular chain hoist rotates the manual chain and the hand wheel to rotate the friction plate ratchet and the brake seat 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.
