7.4 ASSESSMENT FOR SUITABILITY FOR CONTINUED SAFE USE
7.4.1 Assessment for continued safe operation
Cranes that have reached the end of their design life shall be assessed to ensure their suitability for continued use. Where the design life is unknown, this assessment should be carried out at 10-year intervals for the mechanical components and at 25-year intervals for the structure.
The assessment shall also be undertaken where maintenance records indicate repeated failures of any critical component or where the crane has been subjected to an overload greater than 10% of the safe working load for either or both the structure and hoist.
Persons carrying out such an assessment should be supervised by a professional engineer.
NOTES.
1. a cranes design life may not be the same as its actual life and depends on such factors as its classification, usage and its operating environment.
2 Devices are available to record the actual usage of a crane to enable assessment of its remaining design life. Guidance on such devices is given in ISO 12452, 1.
3 Appendix 1. provides guidance on items that may be included in such an assessment.
As part of the assessment, a major inspection of the crane may be necessary (see Clause 7.3.4). -
Is the crane over 25 years old
-
A Crane has a structural Service life of 25 years maximum. After this time period the Crane must be removed from service and full dismantled, internally inspected and repaired and modified to comply with the latest Australian standards or just scrapped.
