The working principle of the hand chain hoist

Xi'an LiBa lifting hand chain hoist is a kind of hand tools, it is through the tugging hand chain, hand sprocket rotation, the friction plate ratchet wheel, the brake seat presses the friction plate ratchet wheel, the brake seat into one piece *** with the same rotation, the teeth of the long axis will rotate the sheet gear, the teeth of the short axis and the spline hole gear. In this way, the lifting sprocket installed on the spline hole gear drives the lifting chain, thus lifting the heavy load smoothly. The ratchet friction plate one-way brake is adopted, which can brake itself under load, and the pawl engages with the ratchet wheel under the action of the spring to ensure the safe operation of the brake.
