How to properly clean and rust-proof the chain hoist?

As a common lifting tool, the chain hoist is widely used in industrial production and daily life. However, since it is often used in harsh environments and is susceptible to pollution and corrosion, correct cleaning and rust-proofing are essential. This article will introduce in detail how to properly clean and rust-proof the chain hoist to extend its service life and ensure its safety performance.

1. Cleaning method of chain hoist

1. Shell cleaning

Use kerosene or professional cleaning agent to clean the shell of the chain hoist. Drop kerosene or cleaning agent on the surface of the hoist and wipe it with a clean rag to remove oil stains and dirt on the surface. Be careful not to let the liquid enter the inside of the hoist to avoid affecting the internal parts. After cleaning, wipe it dry with a clean rag to ensure that there is no residual liquid on the shell.

2. Chain cleaning

The chain is an important part of the chain hoist, and its cleaning method is as follows:
Remove dirt: drop a few drops of kerosene or cleaning agent on the chain and wait for a few minutes for the dirt to be fully soaked. Then wipe the chain with a rag tied to an iron wire or a thin stick to remove dirt and dust from the gap.
Avoid water washing: Never rinse the chain directly with water to avoid rusting the chain.
3. Internal parts cleaning
When cleaning the internal parts of the hand chain hoist, it should be operated by professionals familiar with the hoist mechanism. Use kerosene to clean the internal parts, such as gears and bearings, and add butter for lubrication after cleaning to prevent people who do not understand the performance principle from disassembling and assembling at will.

2. Anti-rust treatment of hand chain hoists
1. Apply anti-rust grease
After use, clean the hoist and apply anti-rust grease, and store it in a dry place to prevent rust and corrosion due to moisture. Add butter to key parts such as gears and bearings to maintain good lubrication and reduce the risk of wear and rust.
2. Regular inspection and maintenance
Check the waterproof coating: The surface of the hand chain hoist usually has a waterproof coating to prevent corrosion and rust after contact with water. If the coating is damaged, it should be repaired or re-applied with anti-rust grease in time.
Keep the brake clean: The friction surface of the brake must be kept clean, and the braking performance must be checked frequently to prevent brake failure from causing heavy objects to fall.
3. Storage environment
Store the hand chain hoist in a dry, well-ventilated environment, away from direct sunlight and moisture. When not in use for a long time, it should be regularly maintained and lubricated to prevent rust during storage.

III. Precautions for use
1. Avoid overloading
The hand chain hoist has its rated load-bearing weight, and it should not be overloaded when in use. Overloading will not only accelerate the wear of the equipment, but may also cause safety accidents.
2. Correct operation
During the lifting operation, the chain should be perpendicular to the ground and the cargo, and the direction of pulling the lifting chain should be in the same plane as the hand chain sprocket. It is forbidden to pull the hand chain obliquely.
3. Regular inspection
Regularly check the various parts of the hand chain hoist, such as chains, bearings, hooks, etc., to ensure that there is no serious wear or damage. If problems are found, they should be replaced or repaired in time.
Through the above cleaning and anti-rust treatment methods, the service life of the hand chain hoist can be effectively extended to ensure its safety and reliability in various environments. I hope the content of this article will be helpful to you and keep your hand chain hoist in good working condition.
