1、 Clean the surface of the electric hoist

The rusting of electric hoists is mainly due to the long-term exposure of the surface to moisture and gas in the air, and the chemical reaction between oxygen in the moisture and gas and steel in the metal, resulting in the long-term accumulation of rust on electric hoists. Therefore, cleaning the surface of the electric hoist is the first step in solving the problem of rust. You can use water, detergent, or acid for cleaning, and after cleaning, wipe the surface dry with a clean cloth.

2、 Apply anti rust oil

After cleaning the surface of the electric hoist, anti-corrosion treatment should be carried out in a timely manner, and the commonly used method is to apply anti rust oil. Before applying anti rust oil, it is necessary to wipe off the water and impurities on the surface, and then apply an appropriate amount of anti rust oil to form a thin film on the surface, which can prevent oxidation and rust.

3、 Regular maintenance

Electric hoists should be regularly maintained and inspected during use. It is very important to regularly clean the surface of the electric hoist, and specialized cleaning agents or tools can be used for cleaning. During use, the weight and frequency borne by the electric hoist will have a certain impact on the hoist itself. During maintenance, it is necessary to pay attention to checking and refueling the hoist.

4、 Pay attention to storage

Electric hoists need to be stored properly when not in use for a long time to avoid moisture and exposure to sunlight. A better method is to store electric hoists in a cool and ventilated place to avoid humidity and rust.

In short, long-term use of electric hoists inevitably leads to rusting problems, but proper cleaning and maintenance can effectively extend the service life and function of electric hoists. At the same time, attention should also be paid to moisture and sun protection during storage. The above are effective measures to solve the problem of rust in electric hoists. By using scientific methods to maintain electric hoists, work safety and efficiency will be effectively improved.
