How to quickly identify whether the parts of the chain hoist are rusted?
As a commonly used lifting equipment, the rust problem of its various parts not only affects its performance, but also affects the safety of use. This article will introduce in detail how to quickly identify whether the parts of the chain hoist are rusted, and how to deal with rust.

1. Identify rusted parts
Chain
The chain is one of the most rusty parts in the chain hoist. When checking the chain, observe whether the chain links are severely corroded and there is no slipping. At the same time, check whether the chain has excessive wear, corrosion, deformation and external damage

Cover
If the outer paint of the cover of the chain hoist falls off, it is easy to cause the internal metal parts to rust. When checking the cover, pay attention to whether there are scratches, wear, deformation, and rust

Hook
The hook is an important part of the chain hoist, and its deformation or rust will seriously affect the safety of use. When checking the hook, confirm whether there is deformation, breakage, cracks, etc., as well as whether there is rust

Gears and bearings
The rust of gears and bearings will affect the smoothness of the operation of the chain hoist. During the inspection, attention should be paid to whether the gears are intact, whether the wheel rod is worn, and whether the cotter pins are intact

Threaded surface
All parts of the chain hoist body and the exposed threaded surface should be coated with calcium-based anti-rust grease or other anti-rust grease to prevent rust

2. How to quickly identify rust
Visual inspection
The most direct method is to observe whether there is rust, deformation or damage on the surface of each part of the chain hoist through visual inspection

Tactile inspection
Touch each part with your hand to feel whether there is any abnormal roughness, which may be a precursor to rust

Functional test
When operating the chain hoist, if you feel that the chain, gears and other parts are not running smoothly, it may be caused by rust

3. Methods for dealing with rust
Physical rust removal
For slightly rusted parts, you can use steel wool or rust-removing sandpaper to wipe and remove the rust on the surface

Chemical rust removal
For parts with severe rust, you can use acidic solutions (such as dilute hydrochloric acid, acetic acid, etc.) to soak, then rinse with clean water, and finally apply a layer of anti-rust grease

Lubrication and maintenance
After cleaning and rust removal, the chain, gears and bearings of the hand chain hoist should be filled with lubricating oil to prevent rusting again

Regular inspection
Regular inspection and maintenance of the hand chain hoist, timely detection and treatment of rust problems, is the key to ensure the normal operation and service life of the hand chain hoist

Conclusion
Quickly identifying whether the various parts of the hand chain hoist are rusted and taking corresponding treatment measures is crucial to ensuring the performance and safety of the hand chain hoist. Through regular inspection and maintenance, the service life of the hand chain hoist can be effectively extended and the safety hazards caused by rust can be reduced.
