DISCARD CRITERIA

RECOMMENDED DO'S & DON'TS

! For single-layer construction, if the reduction in diameter is greater than 8% (eg. 6x7). ! For multiplayer construction, if the reduction in diameter is greater than 5% (eg. 6x19, 6x36 etc.) ! Total no. of visible broken wires exceed 10% of total no. of wires in the rope, in a length of 8 x dia. of rope or 3 or more adjacent broken wires in a stand. ! Evidence of considerable plastic wear or surface embrittlement. ! Localised distortion, damage or kink, bird-caging, crushing. ! Localised diameter reduction or lay variation associated with waviness. ! Collapsed core or one strand broken coupled with wire looseness and bulging. ! Corrosion / chain pitting & associated fatigue of wires. ! Damage due to heat / fire. ! Rope has been subjected to severe shock load or overload due to some accident with equipments. ! End-fitting / attachments damaged or cracked or deformed or worn out.

DO’S ! Lubricate ropes with good quality acid free and moisture free lubricant. ! Regularly inspect the sheaves, rollers or pulleys-the life of a rope largely depends on their conditions. ! Inspect ropes and fittings/terminations periodically. DONT’S ! Do not allow ropes in store to deteriorate ! Do not mishandle ropes when uncoiling or unreeling & allow kinks to form. ! Do not use Langs lay with a swivel ! Do not cut a rope without seizing. ! Do not use rope which is not sufficiently flexible for he size of drum or pulley. ! Do not load the rope beyond its safe working load. Reduction of safety factor may jeopardise not only rope, but also equipment, job and men. Note: Remember - Care in handling, installation, and careful inspection gives more life and enormous dividends.

Note: The inspector should also refer to International Standards like ISO 4309 and BS 6570 or any other relevant standard for the purpose, as a tool, for discarding a wire rope. Authorised Distributor
