Manual hoist maintenance method

1. After use, the gourd should be cleaned and coated with anti-rust grease, and stored in a dry place to prevent the chain hoist from being damp, rusted and corroded.
2. Maintenance and inspection should be carried out by those who are familiar with the hoist mechanism. Clean the hoist parts with kerosene, and lubricate the gears and bearings to prevent random disassembly and assembly by those who do not understand the performance principle of the machine.
3. After the hoist has been cleaned and repaired, it should be tested without load to confirm that it works normally and the brake is reliable before it can be delivered for use.
4. The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent brake failure and heavy objects from falling.
5. The rollers of the left and right bearings of the hoisting chain wheel of the chain hoist can be adhered to the inner ring of the bearing that has been pressed on the journal of the hoisting chain wheel with butter, and then put into the outer ring of the bearing of the wallboard.
6. When installing the braking device of the chain hoist, pay attention to the good meshing between the tooth groove of the ratchet and the claw of the ratchet. The control of the ratchet by the spring should be flexible and reliable. , The friction plate is pressed tightly on the brake seat, and the hand chain wheel is rotated counterclockwise, there should be a gap between the ratchet and the friction plate.
7. For the convenience of maintenance and disassembly, one of the bracelet chains is tied with an open chain (welding is not allowed).
8. During the process of refueling and using the chain hoist, the friction surface of the braking device must be kept clean, and the braking performance must be checked frequently to prevent heavy objects from falling due to braking failure.
