Structural principles and instructions for use of hand chain hoists
As an upgraded version of the fixed pulley, the hand chain hoist completely inherits the advantages of the fixed pulley. At the same time, it adopts the combination of reverse backstop brake reducer and chain pulley block, and has a symmetrically arranged two-stage spur gear rotation structure, which is simple, durable and efficient.
Four major mechanisms of hand chain hoist
It generally consists of a driving device, a chain winding system, an object retrieval device and a safety device. The driving device includes a hand-pulled chain, a hand-pulled sprocket, a brake disc friction plate and a ratchet, etc. The chain winding system includes a baffle
Classification and structural characteristics of hand chain hoists
According to the place of origin, it is divided into: domestic hand chain hoist, imported hand chain hoist
According to the shape, they are divided into: round hand chain hoist, T-shaped hand chain hoist, triangular hand chain hoist, mini hand chain hoist,
