Whether riggers are using synthetic, wire rope, or chain slings, it’s important to protect the sling itself from damage by using the correct equipment and safe rigging practices. An article from the July issue of Crane Hot Line, “Knowledge and Vigilance Required,” provides real world examples of incorrect rigging practices.
The article showcases a series of jobsite photos that offer a visual representation of the damage done to slings and other equipment from improper rigging techniques.
The article’s author, Robert Harrell, President of Safety Management Services, uses the example of synthetic slings being used to lift and set tower sections. Rotating the tower sections from horizontal to vertical caused so much friction that it melted the sling jacket and structural fibers.
LiftGuard® Magnetic Sling Protectors from DICA prevent abrasion damage caused by contact with edges, corners, or protrusions from loads being lifted. LiftGuard sling protectors can be used with all sling types such as synthetic, wire rope, and chain slings. Edge protection is critical in preventing sling failure and is a requirement in current sling safety standards (OSHA 29 CFR 1910.184(c)(9) and ASME B30.9.
Harrell also highlights the importance of safe rigging practices. This includes using the correct slings for the job, inspecting equipment before the lift, and making sure the rigging crew that has been trained by a qualified instructor.
