ABSTRACT:
A sling particularly adapted for use in hoisting heavy objects. The sling is formed in a predetermined length and has loops at each end for connection to the hoisting equipment or for looping the sling about the load which is to be hoisted. The sling comprises a synthetic fabric which, according to the invention, is woven in three plies in which each ply comprises chain warps extending throughout the length of the ply, the plies being interconnected both by the filling yarns and by connecting binder warps. The fabric incorporates load-carrying yarns disposed on opposite sides of the central ply between the central ply and the outer ply. The loadcarrying yarns are rigid, continuous filament yarns, whereas the warp yarns in at least the outer plies are textured yarns, preferably bulked synthetic carpet yarns. The warp yarns in the central ply are preferably dyed to a contrasting color which may serve to signal the occurrence of wear in the fabric.
