Which test is conducted on portable or loose cargo gear, externally pulled to simulate 200% of WLL?

• A. Proof Load Test
• B. Static Load Test
• C. Functional Load Test
• D. Dynamic Load Test

Answer: (A)

Applying a load greater than the rated capacity to portable or loose cargo gear to demonstrate its strength is the essence of a proof load test. By externally pulling the gear to simulate 200% of the Working Load Limit, you’re checking that it can carry loads well beyond its normal use without sustaining permanent deformation or failure. This test provides confidence that the gear will perform safely under unexpected or peak conditions.

Other tests serve different purposes. A static load test checks performance under a static, usually substantial load but doesn’t necessarily require exceeding the WLL. A functional load test verifies that the gear can operate or perform its intended function under load, not that it can withstand overload. A dynamic load test examines behavior under moving or impact loads, focusing on how the gear handles shocks rather than proving its over-capacity strength.

So the test described is the one that proves the gear can endure an overload by external pulling to 200% of WLL.
