Reasons affecting the service life of safety belt

When the safety belt is used for the first time, lie down the rope, thread it into the rope release device from the middle hole, roll and pull it apart, and do not put the safety belt on the disc; Before reuse, the safety belt shall be subject to load test. It can be used only after passing the inspection. If any abnormality is found, it shall be scrapped; Store the safety belt in a dry and ventilated warehouse and keep it clean frequently. Do not touch open fire and acid. Do not collide with sharp objects and do not expose it to the sun.

1. Acid base. Acid and alkali will affect the characteristics of nylon and even completely destroy the strength of nylon. Therefore, when using safety belts in acid and alkali situations, the following factors should be evaluated: types of acid, alkali or other chemicals; Degree and concentration of acid-base exposure.

2. UV. Exposure of the safety belt to continuous ultraviolet light will destroy the strength of the synthetic fiber sling. Visual inspection method for UV damage: the color of sling fades; Sling material hardening; Surface wear occurs where the sling does not often contact the load.

3. Temperature. As the raw material of the safety belt belongs to chemical fiber products, too high temperature is harmful or even destructive to the safety belt. Especially in places with welding operations, it is necessary to prevent sparks generated by electric welding from scalding the safety belt. 4. Sharp edge. When the lifting object has sharp edges, the sharp edges will cause destructive cuts to the safety belt. In order to protect the lifting belt from cuts, a protective lining can be placed between the safety belt and the lifted object.

If the safety belt is no longer used, it must be stored in a clean, dry and well ventilated environment and placed on a shelf away from heat sources, gases that can erode the appearance, chemicals, direct sunlight and other strong ultraviolet radiation.
