Slings should be visually inspected before and after every use to ensure that they have not been damaged. Using appropriate protective products will increase sling longevity and prevent damage to the load. Sling protectors-which may consist of sleeves, pads or shields-are used to protect both the sling and the load. At the same time, slings can cause damage to loads that are easily scratched or crushed. Loads with sharp edges and corners can cut or abrade slings, especially slings made of synthetic materials. A sling calculator can help you determine the appropriate sling length and lifting capacity for your load and hitch style. The sharper the angle of the sling to the load, the more lifting capacity is reduced. Maximum lifting capacity is greatest when the sling angle is 90°. In particular, the angle at which the sling is used will significantly impact its overall lifting capacity. The lifting capacity is determined in part by the material the sling is made of and the diameter of the sling, and in part by the way it is attached to the load. OSHA and the American Society of Mechanical Engineers (ASME) require that slings be tagged with the rated capacity of the sling under different configurations.

DO Pay Attention to Sling RatingsĪll slings are rated for their maximum load capacity. You can also refer to the Web Sling and Tie Down Association (WSTDA) Web Sling and Roundsling Standards. Please consult OSHA Standard 1910.184 and ASME B30.9 – 2018 for more information on safe practices for sling use. They must also receive appropriate safety training, which should cover safe lifting techniques, sling and hitch types, sling capacity determination, equipment care and maintenance, and load weight and center of gravity determination. Workers involved in hoisting and rigging operations should follow OSHA and ANSI/AMSE guidelines for safety. DO Follow Safe Hoisting and Rigging Practices Here are a few dos and don'ts to keep in mind when using your lifting sling. But the biggest impact on safety and performance comes down to how you use-or abuse-your sling. The first step to lifting sling safety is choosing the right sling material.
