    The principle of a chain hoist: The chain hoist rotates by pulling the manual chain and chain wheel, pressing the friction plate ratchet and brake seat together to rotate. The tooth long shaft then rotates the plate gear, tooth short shaft, and 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. Adopting a ratchet friction disc type one-way brake, it can self brake under load, and the pawl engages with the ratchet under the action of the spring, ensuring safe operation of the brake.

    When the chain is twisted, it should not be used. If the hand pulling force is found to be greater than the normal pulling force, it should be immediately stopped and inspected. It is not allowed to forcefully pull, let alone add people to forcefully pull. It is strictly prohibited to use the lower frame of products with double row lifting chains on the two row chains.
