In a static load test, the applied test weight is equivalent to what percentage of WLL?

• A. 200%
• B. 125%
• C. 100%
• D. 150%

Answer: (A)

In a static load test, the goal is to confirm the gear can carry a load well above what it normally handles, using a steady, non-dynamic force. The test weight is taken as 200% of the working load limit (WLL), meaning you apply a load equal to twice the rated working capacity and keep it for the required duration. This substantial margin ensures any hidden flaws—such as material weaknesses, welding defects, or excessive permanent deformation—are revealed under a controlled, static condition before the equipment goes into service. If the member holds that two-times load without yielding or cracking, it demonstrates a safe and reliable strength reserve beyond normal use.
