How to prevent the electric hoist from rusting
The electric hoist is a light and small lifting tool for metal work. There will be some rust on the electric hoist for a long time. However, the following methods can make the equipment difficult to rust and extend the service life of the electric hoist. Here to tell you how to maintain the electric hoist without rust:
Electric hoist is a common lifting and lifting tool, and the general environment can satisfy the electric hoist. But if it is used in some dark and wet or rainy days, it may cause the electric hoist to rust, so how should we prevent the electric hoist from rusting?
First of all, if it is a wire rope type hoist, the surface of the wire rope should be coated with anti-rust lubricant, and under non-operating conditions, the tarpaulin or plastic film should be wrapped on the outside. The bearing of the hook should be filled with calcium-based anti-rust grease to prevent rust, and it should be checked from time to time. The anti-rust effect can achieve the effect of prolonged use.
Then, the surface of the gear parts in the electric hoist gear box is coated with anti-rust grease containing barium petroleum sulfonate, and the construction condition and the integrity of the oil film are regularly checked. If rust is found, use hardwood or bamboo chips to scrape off the rust spots and reapply oil. If the original oil film is damaged or deteriorated, clean it with kerosene or gasoline, and then apply anti-rust grease.
Finally, the exposed surface and exposed thread surface of each part of the electric hoist, which are easy to corrode, should be coated with calcium-based anti-rust grease or other anti-rust grease.
