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. Listed below are just a few dos and don’ts to keep in mind when using your lifting sling.
All slings are rated for his or her 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 set in part by the fabric the sling is made of and the diameter of the sling, and in part by the way it is attached 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 90°. The sharper the angle of the sling to the load, the more lifting capacity is reduced. A sling calculator may help you identify the appropriate sling length 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, particularly slings made of synthetic materials. On the same time, slings can cause damage to loads which can be simply scratched or crushed. Sling protectors—which might encompass 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 Incessantly
Slings ought to be visually inspected before and after every use to ensure that they have not been damaged. OSHA requires periodic formal inspections for all slings, which should be performed annually for slings under normal service and more often for slings used in more rugged conditions. Lift-All offers proof-testing of slings purchased through Pantero and may 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 possibilities that a sling will fail in the course of 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; so long as the core fibers are intact, the sling can proceed to be used.
DON’T Use Slings in the Unsuitable Setting
Temperature, chemical exposure and other environmental factors will all impact sling performance and longevity. Make sure the sling material that you choose is appropriate for the environment in which it will be used. Artificial materials should not be used in high-temperature environments (more than 195°F). If you are working with acids, alkalines, organic solvents, bleaches or oils, check the producer’s specifications to make sure that the sling materials is appropriate with these exposures. Moisture and sun exposure matter, too; artificial materials are inclined to degradation with prolonged UV exposure, while wire rope and chain slings might corrode in damp conditions.
DON’T Abuse Your Sling
Sling failure usually outcomes from misuse or abuse, resembling dragging the sling on the ground, tying knots within the sling, utilizing slings at an excessive angle, failing to protect slings from sharp edges, or allowing sling legs to become kinked. Chemical publicity can also damage slings. Take proper care of your sling, so it can take care of you!
