To operate the Guanhang chain hoist efficiently and safely, it is necessary to be familiar with the working principle of the chain hoist. Only by understanding it can the operation be replaced.

When lifting heavy objects with a chain hoist, pull the manual chain and hand chain wheel clockwise to rotate, pressing the friction plate ratchet and brake seat together for rotation. The long shaft of the teeth will rotate the plate gear, the short shaft of the teeth, and the spline hole gear. In this way, the lifting sprocket installed on the spline hole gear drives the lifting chain, thereby smoothly lifting the heavy object.

When descending, pull the hand zipper counterclockwise to separate the brake seat from the brake pad. The ratchet stops under the action of the pawl, and the five tooth long shaft drives the lifting sprocket to run in the opposite direction, thus smoothly descending the heavy object. Hand pulled hoists generally use a ratchet friction plate one-way brake, which can self brake under load. The pawl engages with the ratchet under the action of the spring, ensuring safe operation of the brake.

The Guanhang chain hoist is easy to operate, portable, and widely used, and is deeply loved in various industries, bringing convenience to people's production and life.
