Proof load testing is necessary to determine the load-bearing capacity of a lifting and rigging structure or equipment. With this test, your rigging hardware can meet the safety standards laid down by OSHA.

Solid weight proof load testing is a subset of proof load testing, where you can use solid load test weights. It is often referred to as the traditional proof load testing method.

We have calibrated equipment and trained staff to ensure thorough solid weight-proof load testing. Our testing can help you ensure safe operations, prevent potential workplace accidents, and also save money in the long run.
