It is important for responsible sling users to realize that chain slings, wire rope slings and wire mesh slings all have their place for proper use and application. Polyester and heavy duty nylon lifting slings have two primary limitations: they are easily damaged by cutting and abrasion and they are susceptible to damage from heat above 194 degrees (F)/90 degrees (C). Chain Slings and Wire Rope Slings offer higher temperature limits of 400 degrees (F). Uncoated wire mesh slings can be used at temperatures of 550 degrees (F) with no reduction in sling work load limits. Heavy duty lifting straps made from webbing, like all lifting slings must be protected from cutting and abrasion by materials of sufficient strength, thickness and construction.
