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 would be unwise from a safety standpoint. By following well-established principles, such as those detailed in the International Standard ISO 4309, 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. SIDIS will assist you to determine the rope condition and will calculate the stage of discard based on ISO 4309 standard rules.
