How to properly maintain and inspect the 45KN Auto Lock Metal Carabiner to extend its service life?

The 45KN Auto Lock Metal Carabiner is a high-strength metal climbing buckle that is widely used in rock climbing, rescue and other outdoor activities. Due to its important safety function, proper maintenance and regular inspection are essential, which can not only extend the service life of the product, but also ensure the safety of the user. Here are some methods and suggestions for maintenance and inspection.

1. Regularly inspect the appearance and function
1.1 Check the appearance for damage
Surface scratches and dents: Check the carabiner for obvious scratches, dents or cracks, especially in the pressure-bearing parts such as the main lock body and door lock.
Corrosion and oxidation: Metal carabiners may corrode due to moisture or salt water environment. Pay attention to check for rust or other signs of oxidation.
1.2 Test the locking function
Automatic locking mechanism: Make sure the automatic locking function operates smoothly without jamming or resistance. When testing, open and close the lock door by hand several times to confirm that it can automatically return to the locked position.
Spring performance: Check whether the lock spring still has sufficient elasticity to prevent accidental loosening during use.
2. Maintenance steps
2.1 Cleaning and maintenance
Daily cleaning:
Wipe the surface dust and dirt with a soft cloth.
For stains that are more difficult to remove, use a neutral detergent and warm water to clean, and then wipe thoroughly with a dry cloth.
Deep cleaning:
If sand or mud enters the locking mechanism in the use environment, rinse with warm water and gently clean with a brush. Avoid using high-pressure water to avoid damaging internal parts.
After cleaning, add a small amount of lubricating oil (such as silicone oil or special mechanical lubricant) to the pivot point and spring position to ensure smooth movement.
2.2 Prevent corrosion
Avoid humid environment: Try not to expose the Carabiner to humid environments for a long time, such as rainy days or at the seaside. After use, it should be cleaned immediately and dried completely.
Rust prevention: If there is slight rust on the surface of the product, wipe it with a rust inhibitor and apply a layer of protective oil after cleaning to isolate moisture from the air.
2.3 Proper Storage
Storage location: Store the Carabiner in a dry, well-ventilated place, avoiding high humidity and highly corrosive chemical environments.
Avoid friction and collision: Store separately to prevent scratches or deformation caused by friction between the Carabiner and other metal equipment.
3. Inspection frequency
High-frequency use: If the Carabiner is frequently used in a high-pressure, high-load environment (such as professional rock climbing or rescue), it is recommended to check before and after each use.
Low-frequency use: For occasional use, it is recommended to conduct a comprehensive inspection once a quarter.
Special circumstances: If the Carabiner has experienced a major impact or fall, even if the surface appears intact, it should be stopped and replaced immediately to avoid risks caused by hidden damage.
4. How to deal with a damaged Carabiner
Stop using: If the Carabiner is found to have serious scratches, deformation, cracks, or the automatic locking function fails, it should be stopped immediately.
Proper disposal: Discard the damaged Carabiner properly to avoid misuse or re-entry into the system, which may cause safety hazards.
5. Precautions for extending service life
Choose the appropriate load range: Make sure that the weight and pressure of the 45KN Auto Lock Metal Carabiner are within the product specifications when using it, and avoid overloading.
Avoid violent operation: Do not use excessive force when opening and closing the door to avoid damaging the locking mechanism.
Replace regularly: Even if the carabiner seems intact, metal fatigue is inevitable as the use time increases. It is recommended to consider replacing the product according to actual conditions after a few years of cumulative use.
