scope:

This International Standard establishes general principles forthe care and maintenance, and inspection and discard of steel wireropes used on cranes and hoists. This International Standard isapplicable to those ropes used on the following types of cranes,the majority of which are defined in ISO 4306-1: a) cable andportal cable cranes; b) cantilever cranes (pillar jib, wall orwalking); c) deck cranes; d) derrick and guy derrick cranes; e)derrick cranes with rigid bracing; f) floating cranes; g) mobilecranes; h) overhead travelling cranes; i) portal or semi-portalbridge cranes; j) portal or semi-portal cranes; k) railway cranes;l) tower cranes; m) offshore cranes, i.e. cranes mounted on a fixedstructure supported by the sea bed or on a floating unit supportedby buoyancy forces. This International Standard applies to rope oncranes used for hook, grabbing, magnet, ladle, excavator orstacking duties, whether operated manually, electrically orhydraulically. This International Standard also applies to ropeused on hoists and hoist blocks. In view of the fact that theexclusive use of synthetic sheaves or metal sheaves incorporatingsynthetic linings is not recommended when single-layer spooling atthe drum, due to the inevitability of wire breaks occurringinternally in large numbers before there is any visible evidence ofany wire breaks or signs of substantial wear on the periphery ofthe rope, no discard criteria are given for this combination.
