AS 3850.1 – 2015 Prefabricated Concrete Elements Part 1: General Requirements
ISO 4309:2007 Cranes – Wire Ropes -Care and Maintenance, Inspection and Discard establishes general principles for the care and maintenance, and inspection and discard of steel wire ropes used on cranes and hoists.
A wire rope on a crane is regarded as an expendable component, requiring replacement when the results of inspection indicate that its condition has diminished to the point where further use might be unsafe.
By following well- establish principles such as those detailed in this document, along with any additional specific instructions provided by the manufacturer of the crane or hoist and/or by the manufacturer of the rope, this point should never be exceeded.
When correctly applied, the discard criteria given in this document are aimed at retaining an adequate safety margin. Failure to recognize them can be extremely harmful, dangerous and damaging.
To assist those who are responsible for “care and maintenance” as distinct from those who are responsible for “inspection and discard”, the procedures are conveniently separated.
