Step one to lifting sling safety is choosing the proper sling material. But the biggest impact on safety and performance comes down to how you employ—or abuse—your sling. Here are a couple of 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 decided in part by the material the sling is made of and the diameter of the sling, and in part by the way it is connected to the load. In particular, the angle at which the sling is used will significantly impact its total lifting capacity. Most 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 establish the appropriate sling size and lifting capacity for your load and hitch style.
DO Use Proper Protection for Slings
Loads with sharp edges and corners can reduce or abrade slings, especially slings made of artificial materials. On the identical time, slings can cause damage to loads which can be easily scratched or crushed. Sling protectors—which could 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 Examine Slings Incessantly
Slings must be visually inspected earlier than and after each use to make sure that they have not been damaged. OSHA requires periodic formal inspections for all slings, which must be conducted annually for slings under normal service and more often for slings used in more rugged conditions. Lift-All presents proof-testing of slings purchased by way of 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 improve the possibilities that a sling will fail throughout 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; as long as the core fibers are intact, the sling can proceed to be used.
DON’T Use Slings within the Wrong Setting
Temperature, chemical exposure and different environmental factors will all impact sling performance and longevity. Make certain the sling materials that you select 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 manufacturer’s specs to ensure that the sling material is appropriate with these exposures. Moisture and sun publicity matter, too; synthetic supplies are prone to degradation with prolonged UV exposure, while wire rope and chain slings could corrode in damp conditions.
DON’T Abuse Your Sling
Sling failure usually results from misuse or abuse, such as dragging the sling on the ground, tying knots in the sling, utilizing slings at an extreme angle, failing to protect slings from sharp edges, or permitting sling legs to turn out to be kinked. Chemical exposure may damage slings. Take proper care of your sling, so it can take care of you!
