Increase the service life of the hand chain hoist
If it is not used for a period of time, you should apply anti-rust grease to the hook and frame to prevent the hook from oxidizing.
When lifting corrosive items, the hooks should be packaged to prevent corrosive objects from corroding the hooks.
The hook should be cleaned and wiped after each use, and placed in a ventilated place to dry.
Because the hook is the component that carries the heavy object, we must not overload it during the lifting process.
Principle of hand chain hoist
By pulling the manual chain and the hand chain wheel, the hand chain hoist presses the friction plate ratchet and brake seat into one body and rotates together. The long tooth axis rotates the plate gear, short tooth axis and Spline hole gear. The lifting sprocket installed on the spline hole gear drives the lifting chain to lift the heavy object smoothly. The ratchet friction disc type one-way brake can brake on its own under load. The pawl engages with the ratchet under the action of the spring, and the brake works safely. As an upgraded version of the fixed pulley, the hand chain hoist completely inherits the advantages of the fixed pulley. At the same time, it adopts the combination of reverse backstop brake reducer and chain pulley block, and symmetrically arranges the two-stage spur gear rotation structure, which is simple, durable and efficient.
