The Advantages Of The Chain Hoist

- Jul 29, 2019-

      As an upgraded version of the fixed pulley, the chain hoist completely inherits the advantages of the fixed pulley. At the same time, the combination of the reverse speed brake and the chain pulley block, the symmetrical arrangement of the secondary spur gear rotation structure is simple, durable and efficient.

      The hand hoist rotates the manual chain and the hand wheel to rotate the friction plate ratchet and the brake seat 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.
