The following are some effective measures for rust prevention of explosion-proof chain hoists:

1、 Surface coating treatment

anticorrosive paint:

Coating a layer of anti rust paint on the metal surface of the crane can effectively isolate moisture and oxygen in the air, slowing down the corrosion rate.

Choose high-quality anti rust paint and apply it correctly according to the instructions to ensure even coating and no omissions.

Lubricating oil or diesel:

Applying an appropriate amount of lubricating oil or diesel on the surface of the equipment can form a protective film, reducing the contact between metal and air.

This method is suitable for short-term rust prevention, but other rust prevention measures should be considered during long-term storage.

2、 Regular maintenance and inspection

Regular inspection:

Regularly inspect the crane to promptly detect and address rust and corrosion points.

For areas that have already rusted, mechanical or chemical methods should be used to thoroughly remove the rust and perform rust prevention treatment again.

Environmental monitoring:

Pay attention to indicators such as humidity, temperature, and corrosive substance content in the environment where the crane is located.

In high humidity and highly corrosive environments, the frequency and intensity of rust prevention measures should be increased.

3、 Using corrosion-resistant materials

Stainless steel material:

In the manufacturing process of cranes, corrosion-resistant materials such as stainless steel are preferred.

Stainless steel material has excellent corrosion resistance and can significantly improve the service life of cranes.

Alloy material:

Some alloy materials also have good corrosion resistance and can be selected for use according to actual needs.

4、 Covering and Protection

Cover protection:

When the crane is not in use, especially in outdoor environments, proper covering and protection measures should be taken.

Cover the crane with waterproof cloth, plastic film and other materials to reduce the erosion of the crane by natural factors such as rainwater and sunlight.

Indoor storage:

If conditions permit, the crane should be stored indoors to reduce the corrosive impact of the external environment on the crane.

5、 Professional anti-corrosion treatment

Chemical soaking treatment:

Crane components can be soaked in a specific chemical medium to form a dense protective film and improve corrosion resistance.

Electrochemical protection:

The use of electrochemical methods such as cathodic protection or anodic protection can further slow down the corrosion rate of cranes.
