As an upgraded version of the fixed pulley, the hand chain hoist fully inherits its advantages. It combines a reverse-braking reducer with a chain pulley system, featuring a symmetrically arranged two-stage spur gear rotation structure, making it simple, durable, and efficient.
By pulling the manual chain, the hand chain wheel rotates, pressing the friction plate ratchet and brake seat together for rotation. This causes the long gear shaft to rotate the plate gear, the short gear shaft, and the splined gear. In this way, the lifting sprocket mounted on the splined gear drives the lifting chain, thus smoothly lifting the heavy object.
The ratchet friction plate type one-way brake automatically brakes under load. The pawl engages with the ratchet under spring pressure, ensuring safe brake operation.
When it's time to lower the heavy object, simply gently pull the brake to release it. The object's own weight, combined with appropriate chain pullback speed control, allows for precise and safe lowering.
