14.7.2 Post Repair Verification and Record Keeping

In the case of slings of welded construction, heat treatment will be required following a repair. In this case the repaired sling will usually be verified by way of a proof test and thorough examination. In the case of slings with mechanical joining devices, a repair will consist simply of fitting a manufacturer’s certified spare part and heat treatment is therefore not necessary. In this case the repaired sling will usually be verified by way of a thorough examination. The records of the sling should be amended taking account of the replacement parts fitted.

New slings manufactured to the most common current standards will be issued with a Manufacturer’s Certificate in addition to, although possibly combined with, any documentation required by the applicable national legislation, giving details of the sling and its WLL. However, slings to other standards will usually be accompanied by a manufacturer’s record of proof load testing. These documents form an important part of the record of the sling. They should be retained and cross referenced to the sling’s historical records for inspection by the Competent Person or local enforcing authority.

Hooks and other similar devices provided for lifting should be of a type that reduces the risk of the load becoming displaced from the hook or other devices. This requirement can be met by the use of hooks with safety devices or by the use of ‘C’ hooks.
