This document 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 crosSoOver 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 amethod for assessingthe combined effect of deterioration at any position in the rope. This document is applicable to those ropes used on the following types of cranes, the majority of which are defined in ISO 4306-1: al cable and portal cable cranes; D) cantilever cranes (pillar jip, wall or walking); C] deck cranes; dj derrick and guy derrick cranes; el derrick cranes with rigid bracing; 们 floating cranes; g) mobile cranes; hj) overhead travelling cranes; 让 portal or semi-portal bridge cranes; portal or semi-portal cranes; 多railway cranes; ]) tower cranes; Imj offshore cranes, i.e. cranes mounted on afixed Structure Supported bythe sea bed or on afloating unit Supported by buoyancy forcesS. This document applies to rope on cranes, winches and hoists used for hook, grabbing, magnet, ladle， excavator Or Stacking duties whether operated manually electrically or hydraulically. It also applies to rope used on hoists and hoist blocks. NOTE In view of the fact that the exclusive use of Synthetic Sheaves or metal Sheaves incorporating Synthetic linings is not recommended when single-layer Spooling at the drum, due to the inevitability of wire breaks occurring internally in large numbers before there is any visible evidqence of any wire breaks or signs of Substantial wear on the periphery ofthe rope, no discard criteria are given for this combination，
