Advanced performance structure, compact size, light weight, reliable performance, easy operation, wide application range. It is very convenient for lifting heavy loads, loading and unloading, equipment maintenance, and cargo handling. It can also be installed on suspended I-beams, curved tracks, jib crane guide rails, and fixed lifting points for lifting heavy loads. The standard chain hoist features an independent transmission system, a sealed transmission with a two-stage coaxial gear mechanism, and a long-life oil bath lubrication system. The powder metallurgy clutch of the electric hoist serves as an overload protection device, and the braking system uses disc-type DC electromagnetic field brakes, which provide a large braking torque, stability, rapid response, and low noise.
