How to deal with the rust of explosion-proof electric hoist

The corrosion treatment of the explosion-proof electric hoist cover easily deforms the shell and is difficult to store. The appearance will be affected, and there is a risk of scratching at any time during use. Rusty internal parts will increase the friction between the parts. Excessive parts consumption will increase costs. In addition, it consumes the motor and shortens the service life of the motor. The rust of explosion-proof electric hoist is still very harmful, so how to deal with rust?

The brake failure of the explosion-proof electric hoist will cause serious consequences. Braking failure is one of the common failures of explosion-proof electric hoist. Brake failure is very important. But the novelty is that if we can detect and take measures in time, then we can avoid dangerous situations. It can be said that if the brake is not detected in time, the hook will exceed the limit position. In severe cases, the motor will heat up and the motor will burn.
