Step one to lifting sling safety is choosing the right sling material. But the biggest impact on safety and performance comes down to how you use—or abuse—your sling. Here are a few dos and don’ts to keep in mind when utilizing your lifting sling.
All slings are rated for their maximum load capacity. OSHA and the American Society of Mechanical Engineers (ASME) require that slings be tagged with the rated capacity of the sling under totally different configurations. The lifting capacity is decided in part by the fabric the sling is made of and the diameter of the sling, and in part by the way it is hooked up to the load. In particular, the angle at which the sling is used will significantly impact its overall lifting capacity. Maximum lifting capacity is greatest when the sling angle is ninety°. The sharper the angle of the sling to the load, the more lifting capacity is reduced. A sling calculator might help you identify the appropriate sling size and lifting capacity on your load and hitch style.
DO Use Proper Protection for Slings
Loads with sharp edges and corners can minimize or abrade slings, especially slings made of synthetic materials. At the similar time, slings can cause damage to loads that are simply scratched or crushed. Sling protectors—which may include sleeves, pads or shields—are used to protect each the sling and the load. Utilizing appropriate protective products will enhance sling longevity and stop damage to the load.
DO Inspect Slings Often
Slings should be visually inspected before and after each use to make sure that they have not been damaged. OSHA requires periodic formal inspections for all slings, which should be conducted yearly for slings under regular service and more continuously for slings utilized in more rugged conditions. Lift-All provides proof-testing of slings purchased through Pantero and might provide required inspection documentation for OSHA.
DON’T Use a Sling That is Damaged
Cuts, abrasions and fatigue damage significantly reduce the load capacity of the sling and increase the probabilities that a sling will fail through the lift. Slings that show signs of wear or damage should be taken out of circulation immediately. One exception is the colored roundsling, which has a protective tubular jacket over the load-bearing core. Minor damage to the jacket will not impact the load capacity of the sling; as long as the core fibers are intact, the sling can proceed to be used.
DON’T Use Slings in the Wrong Environment
Temperature, chemical publicity and different environmental factors will all impact sling performance and longevity. Make positive the sling material that you choose is appropriate for the surroundings in which it will be used. Artificial supplies shouldn’t be utilized in high-temperature environments (more than 195°F). If you’re working with acids, alkalines, natural solvents, bleaches or oils, check the manufacturer’s specs to make sure that the sling material is suitable with these exposures. Moisture and sun exposure matter, too; artificial materials are susceptible to degradation with prolonged UV exposure, while wire rope and chain slings could corrode in damp conditions.
DON’T Abuse Your Sling
Sling failure typically results from misuse or abuse, reminiscent of dragging the sling on the ground, tying knots within the sling, using slings at an extreme angle, failing to protect slings from sharp edges, or allowing sling legs to turn out to be kinked. Chemical publicity may damage slings. Take proper care of your sling, so it can take care of you!
