As we all know, the group hoist electric hoist is a lifting tool for metal work. As long as it is metal, it will rust, and after rusting, there will be problems such as safety and shortening of its service life. So how do we prevent rusting of group hoist electric hoist and extend the service life of electric hoist? Let me explain to you how to prevent the electric hoist from rusting.
1. The exposed surface of the processed parts of the group crane electric hoist and the exposed thread surface of the group crane electric hoist, etc., should be coated with calcium-based anti-rust grease or other anti-rust grease
2. In the bearing of the group crane electric hoist hook, calcium-based anti-rust grease should be injected to prevent rust. It is necessary to check the anti-rust effect from time to time, so that the effect of extended use can be achieved.
3. The surface of the gear parts in the group crane electric hoist gear box is coated with anti-rust grease containing barium petroleum sulfonate, and it is necessary to regularly check the construction and protect the integrity of the oil film. If you find that the electric hoist of the group crane is corroded, you need to scrape off the rust spots with hardwood or bamboo chips and reapply oil. If the original oil film is damaged or deteriorated, clean it with kerosene or gasoline, and then apply anti-rust grease.
4. If steel wire rope hoist is used, the surface of the steel wire rope should be coated with anti-rust lubricating oil, and under non-operating conditions, the tarpaulin or plastic film should be wrapped on the outside.
Everyone must keep this in mind, so that the rust of the electric hoist can be reduced, and at the same time, the safety of the electric hoist can be improved and the service life of the electric hoist can be extended.
