Step one to lifting sling safety is selecting the best 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 using 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 different configurations. The lifting capacity is determined 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 general lifting capacity. Maximum lifting capacity is greatest when the sling angle is 90°. The sharper the angle of the sling to the load, the more lifting capacity is reduced. A sling calculator may also help you determine the appropriate sling length and lifting capacity for your load and hitch style.
DO Use Proper Protection for Slings
Loads with sharp edges and corners can lower or abrade slings, particularly slings made of artificial materials. On the similar time, slings can cause damage to loads which can be easily scratched or crushed. Sling protectors—which could consist of sleeves, pads or shields—are used to protect both the sling and the load. Utilizing appropriate protective products will enhance sling longevity and forestall damage to the load.
DO Examine Slings Regularly
Slings should be visually inspected before and after every use to ensure that they haven’t been damaged. OSHA requires periodic formal inspections for all slings, which have to be performed yearly for slings under regular service and more regularly for slings used in more rugged conditions. Lift-All gives proof-testing of slings purchased via Pantero and might provide required inspection documentation for OSHA.
DON’T Use a Sling That’s Damaged
Cuts, abrasions and fatigue damage significantly reduce the load capacity of the sling and enhance the chances that a sling will fail in the course of the lift. Slings that show signs of wear or damage must 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; so long as the core fibers are intact, the sling can continue to be used.
DON’T Use Slings in the Improper Atmosphere
Temperature, chemical publicity and other environmental factors will all impact sling performance and longevity. Make certain the sling material that you select is appropriate for the setting in which it will be used. Synthetic materials shouldn’t be utilized in high-temperature environments (more than 195°F). In case you are working with acids, alkalines, natural solvents, bleaches or oils, check the producer’s specifications to ensure that the sling material is compatible with these exposures. Moisture and sun publicity matter, too; artificial materials are prone to degradation with prolonged UV exposure, while wire rope and chain slings might corrode in damp conditions.
DON’T Abuse Your Sling
Sling failure typically outcomes from misuse or abuse, reminiscent of dragging the sling on the ground, tying knots within the sling, utilizing slings at an extreme angle, failing to protect slings from sharp edges, or allowing sling legs to grow to be kinked. Chemical publicity may damage slings. Take proper care of your sling, so it can take care of you!
