Proof tests can be conducted in conjunction with rail lifts.

• A. True
• B. False
• C. Only with written authorization
• D. Not specified

Answer: (A)

Proof tests verify that a crane and its attachments can safely carry their rated loads by applying a defined test load. They’re not limited to separate, stand-alone operations—these tests can be performed during related lifting work, such as rail lifts, as long as you follow the safety rules, use a load within the specified limits, and supervise the procedure. The key is to conduct the test under the manufacturer’s instructions and applicable standards, with proper rigging, stabilization, exclusion zones, and controlled monitoring to ensure there’s no excessive deflection or unexpected behavior. This flexibility allows validation of crane performance without needing a separate, isolated setup, which is why the statement is correct.
