The Case of the OVERLOADED SLING

摘要

Workers use slings (in conjunc-tion with cranes and other lifting machines) to move heavy loads that would be difficult to handle by other means. Slings may be constructed of chain, wire rope, metal mesh, syn-thetic fibers, webbing and other ma-terials. As Figure 1 illustrates, loaded slings can sometimes fail, with potentially devastating effects for anyone working nearby.
