Load and Deflection Testing

Load testing and deflection testing plays a crucial role in ensuring the safety and compliance of cranes, hoist and other lifting equipment outlined by the Australian 1418 & 2550. While load testing is explicitly required at commissioning, it is also recommended during major inspections and 3rd party inspections to validate functions and mitigate risks.

During commissioning, various tests are conducted, including applying maximum rated capacity, measuring deflection, checking hoist brake function, testing travel and traverse motions, and evaluating electrical system performance. These tests ensure safe operation and are documented for record-keeping purposes.

Although load testing is not specifically required during major inspections, it is considered essential in validating structural integrity, emergency functions, and braking systems. We recommend a 110% overload test as part of the Major Inspection Verification Plate Requirements.

Overall, load testing is critical for crane safety and compliance. Many cranes lack documentation satisfying load testing requirements, making it crucial for crane owners to prioritise suitable load test programs to meet their responsibilities under the OHS Act and Regulations.
