The service life of slings usually ranges from 2 to 5 years.
The specific service life depends on a variety of factors, including the quality of the sling material, the environment in which it is used, the load weight, the frequency of use, and the maintenance. High-quality lifting belts can be used for more than 15 years with proper maintenance, while poorer lifting belts may only be used for about 5 years. It should be noted that lifting belts that have exceeded their service life may cause safety hazards.
