Under which condition is lifting 125% of rated load allowed?

Under which condition is lifting 125% of rated load allowed?

• A. For test purposes only
• B. After supervisor approval
• C. On written approval by the OCHS/OSHA department
• D. Never

Answer: (A)

Lifting 125% of the rated load is a controlled test, not a normal operating lift. The rated load represents the maximum load the crane is designed to handle safely under regular use, so lifting more than that isn’t allowed in daily operations. A proof-load test uses 125% to verify the crane’s strength and structural integrity under a higher-than-normal load, but it is done only under a formal test procedure in a controlled setting. So, this higher load is permitted only for test purposes, not for routine lifting.
