BS ISO 4309:2017 establishes general principles for the care and maintenance, and inspection and discard of steel wire ropes used on cranes and hoists.In addition to guidance on storage, handling, installation and maintenance, this document provides discard criteria for those running ropes which are subjected to multi-layer spooling, where both field experience and testing demonstrate that deterioration is significantly greater at the crossover zones on the drum than at any other section of rope in the system.It also provides more realistic discard criteria covering decreases in rope diameter and corrosion, and gives a method for assessing the combined effect of deterioration at any position in the rope.Cross References:ISO 17893EN 12927:2016ISO 4301-1:1986ISO 16625ISO 2408IMCA SEL 023ASTM E1571-11 (2016)e1ISO 4306-1All current amendments available at time of purchase are included with the purchase of this document.
