In the rigging and lifting industries, proof tests are regularly performed to ensure that the equipment to be used can withstand the load it was manufactured to handle. These tests are performed for several reasons – specification requirement, manufacturer’s recommendation, and customer request are the most common.
Why Proof Test?
As mentioned, we perform proof tests for a variety of reasons. One such test commonly performed in the business is a proof load test. A heavy-duty undertaking, a proof load test unveils the true strength of a piece of rigging or lifting gear. Here’s everything you need to know about this specific type of test, as well as how to keep your crew safe during one.
What Is a Proof Load Test?
A proof load test is just what it sounds like: it proves whether a piece of rigging equipment can bear the load it is designed to. The test is administered in a controlled, measured fashion with a particular multiple of the maximum designed load (generally 1.1 to 1.5 times) and a specified length of time. After the test is completed, the operator will issue a certification confirming the workable load of the wire rope or other rigging component in question.
Why Proof Load Testing Is Critical
Whether the rig is overdue for a full inspection, the newly minted wire rope is being put to the test, or older equipment is being evaluated to determine if it is still fit for use, a proof load test is an immensely valuable tool. Every rigging component in the operation should be tested regularly, and a proof load test is one of the most complete and strenuous methods for doing so. Testing also helps keep the rigging equipment and the business as a whole within the boundaries of the OSHA, Department of Labor, and manufacturers’ codes that govern the industry.
Entrust the Proof Load Test to Professionals
The best way to keep your employees safe during a proof load test is to entrust the entire ordeal to trained professionals. Proof load tests are incredibly dangerous if not done with the proper equipment and control measures, as breakage can occur.
At Southwest Wire Rope, we provide proof load testing and destructive (break) testing of various lifting devices up to 1.7 million lbs.

In reality, the advent of performing the test and verifying the strength of the equipment is also keeping your crew safe. Using wire rope or lifting gear until failure is a dangerous proposition and never recommended. Instead, get your equipment certified with a proof load test and gain the peace of mind your professionals deserve.
