The following is a detailed answer to the question of whether rusty chain hoists can be used and how to prevent corrosion:

1、 Can rusty chain hoist be used

A rusty chain hoist can continue to be used under specific conditions, but it needs to be judged based on the degree and location of rust.

Determine the degree of rust:

If rust only appears sporadically and does not appear at the dangerous section of the chain (such as the load-bearing part), and the overall strength of the chain is not affected, then such a chain hoist can continue to be used after proper maintenance and lubrication.

However, if the rust is severe and has already affected the strength and load-bearing capacity of the chain, or appears in critical parts of the chain, then such a chain hoist needs to be replaced in a timely manner to ensure safe use.

Consider safety factors:

Rusted chains may experience problems such as jamming, poor operation, and even breakage due to insufficient strength during use, leading to safety accidents. Therefore, when deciding to continue using rusty chain hoists, safety factors must be fully considered.

2、 How to prevent chain corrosion

To prevent rusting and corrosion of the chain, the following measures can be taken:

Regular maintenance and lubrication:

Regular maintenance and lubrication of the chain is an effective method to prevent rusting. Using lubricating oil can reduce friction and wear between the chain and sprocket, while forming a protective film to prevent direct contact between the chain and oxygen and water vapor in the air.

Surface treatment:

Surface treatment of the chain is also a means of preventing rust. For example, the chain can be treated with blackening or galvanizing to form an oxide film or galvanizing layer on its surface, thereby isolating it from the erosion of air and moisture.

Storage environment:

When storing chains, a dry, ventilated, and non corrosive gas environment should be selected. Avoid prolonged exposure of the chain to damp, dusty, or corrosive environments to reduce the risk of rusting.

Timely replacement:

For chains that have already rusted, if the rust is severe and affects safety, they should be replaced with new chains in a timely manner. Do not continue to use chains with safety hazards due to cost savings.

Regular inspection:

Regularly inspect the chain, including checking for wear, cracks, deformation, etc. Identify problems and handle them promptly to ensure the normal use and safe operation of the chain hoist.
