1. When the lifting object has sharp edges, these sharp edges will cause destructive cuts to the lifting belt. In order to protect the lifting belt from being cut, a protective lining can be placed between the lifting belt and the hanging object , You can also use special corner guards for slings.
2. Prolonged exposure to ultraviolet light will destroy the strength of synthetic fiber slings. It is recommended to use the following methods to avoid the influence of ultraviolet light or arc welding light: when not in use, store the
Sling in a ventilated, cool and dry place; check the sling once or more times a week according to the use of the sling; Visual inspection of UV damage: discoloration of slings, hardening of material, surface wear at areas not frequently exposed to loads; contact the manufacturer for a test test on slings that are continuously exposed to UV light.
3. Acids will affect the properties of nylon, and even completely destroy the strength of nylon; many acids will not affect the properties of polyester, but some acids will cause low to moderate damage to polyester.
4. Many alkalis will not affect the properties of nylon, but some alkalis will cause low to moderate damage to nylon; alkalis will affect the properties of polyester, or even completely destroy the strength of polyester; use synthetic fiber hoisting in places with acid and alkali When carrying, the following factors should be evaluated first: The type of acid, alkali or other chemical; The degree and concentration of acid and alkali exposure.
5. Because the raw material of the sling is a chemical fiber product, too high temperature can damage or even destroy the synthetic fiber sling. Especially in places with welding operations, it is necessary to prevent the sparks generated by electric welding from burning the sling.
The above are the factors that affect the performance of the sling. Paying attention to these can increase the service life of the sling and reduce the cost of use.
