Chain lever hoist as the upgraded version of fixed pulley , has all the advantages of the fixed pulley, and the combination of reverse non-return brake deceleration device and chain pulley, symmetrical arrangement of two gear rotating, which is simple, durable and high efficiency.
Manual lever chain hoist by rotate by pulling drag chain and chain wheel, the friction plate ratchet wheel and the brake seat are pressed into one to rotate together, the tooth long axis turn the piece gear, gear shaft and short splined gear. Then, the chain wheel arranged in the splined gear drive the chain, thus smoothly lifting the weights.The friction ratchet one-way brake, can automatically brake under load. Under the action of the spring, the pawl is engaged with the ratchet wheel, brake safety work.
