1、 When the lifting object has sharp edges, these sharp edges can cause destructive cuts to the lifting belt. To protect the lifting belt from cuts, a protective lining can be placed between the lifting belt and the object being lifted, or a special corner guard for the lifting belt can be used.
2、 Prolonged exposure to ultraviolet light will damage the strength of synthetic fiber sling. The following methods are recommended to avoid the influence of ultraviolet light or arc welding light as far as possible: when not in use, store the lifting belt in a ventilated, cool and dry place; Inspect the sling once or more a week according to the use of the sling; Visual inspection method for ultraviolet damage degree: the color of the lifting belt is faded, the material is hardened, and the surface is worn at the place where the load is not often contacted; Contact the manufacturer to test the lifting belt continuously exposed to ultraviolet radiation.
3、 Acid 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; Alkali will affect the properties of polyester, and even completely destroy the strength of polyester; When using synthetic fiber sling in the presence of acid and alkali, the following factors should be evaluated first: the type of acid, alkali or other chemicals; The degree and concentration of acid and alkali exposure.
5、 As the raw material of the lifting belt is chemical fiber products, the high temperature may cause damage or even damage to the synthetic fiber lifting belt, especially in the place with welding operation, it is necessary to prevent the sparks generated by electric welding from scalding the lifting belt.
The above are the factors that affect the performance of the lifting belt. Note that these can improve the service life of the lifting belt and reduce the use cost.
