Try to prevent unnecessary strand distortion as this may result in weakness when under tension. Handling and CARING FORYOUR ROPE Ropes provideoptimum performance Rope control Inspect your rope regularly especially afterfall. Slide the rope through a clenched Newton. '. s .

MECHANICAL ENGINEER. A hoisting device use chain, fibre or wire rope as its lifting medium. . Wire rope consists of several strands laid (or ‘twisted’) together like a helix.. Each strand is likewise made of metal wires laid together like a helix. . Advantages over chains:. Lighter weight. Less susceptibility to damage from jerks. Silent operation even at high working speeds. Greater reliability in operation. Wire Ropes.
