As an indispensable flexible lifting tool in hoisting operations, lifting slings are widely used in construction, equipment handling, logistics and warehousing, and other fields due to their advantages of light weight, easy operation, and no damage to the surface of lifted objects. In actual operating scenarios, lifting slings are mostly used outdoors. However, high temperatures and intense sunlight occur frequently in summer. Ultraviolet (UV) rays, as invisible yet highly penetrating radiation, have become a key factor affecting the service life and operational safety of lifting slings, requiring great attention from operators and managers.
In fact, as long as scientific usage and maintenance methods are mastered, the negative impacts caused by UV rays can be effectively avoided, and the service life of lifting slings can even be extended. In daily use, first of all, operation planning should be well done to avoid outdoor hoisting operations during the period of strongest UV radiation (10:00-16:00 at noon in summer) as much as possible. If operations are unavoidable during this period, special sunshades or awnings should be equipped for the lifting slings to reduce the time they are directly exposed to sunlight.
