5.9.3 Wire Rope Slings
1) Wire rope is manufactured from a number of single wires which are twisted together to form a strand. There can be any number of single wires in a strand and the single wires are laid round a core of fiber or steel. To make up wire rope, the strands themselves are then twisted round a core of fiber or steel. Obviously there can be great variety in the arrangement of wire and strands.
2) The safe working load of a wire rope is determined from its guaranteed breaking load. In all cases, the manufacturer’s own recommended SWL should be strictly followed.
3) Wire rope slings that are damaged or defective will be destroyed by the subcontractor in place.
