What does a pre-shift inspection of crane controls typically include?
Answer: Verifying that all control labels match the operator's training manual exactly
Pre-shift control inspection verifies that all crane functions respond correctly to operator input, that controls return to neutral when released, and that guards and labels are in place.
What is the purpose of the crane's load moment indicator (LMI), and what should the operator do if it malfunctions?
Answer: LMI monitors the relationship between the actual load and rated capacity; a malfunction requires taking the crane out of service
The LMI monitors actual load conditions versus rated capacity and triggers warnings or function cutouts when limits are approached. An LMI malfunction is a removal-from-service condition under OSHA regulations.
When inspecting crane hooks during pre-operation inspection, which of the following conditions requires removing the hook from service?
Answer: A 10% increase in throat opening compared to the manufacturer's specifications
A 10% increase in throat opening indicates plastic deformation (stretching) of the hook under overload, which requires immediate removal from service per ASME B30.10.
Before beginning operations each day, the crane operator should perform a 'check swing' or 'dry run.' What does this involve?
Answer: Carefully moving the crane through planned lift motions without a load to verify all systems respond properly
A check swing or dry run involves moving the crane through the planned lift path without a load to verify that all crane systems function properly and that the lift path is clear of obstructions.
What is the minimum frequency for performing 'frequent' (daily/monthly) crane inspections under ASME B30.5?
Answer: Before each shift for cranes in regular service
ASME B30.5 requires frequent inspections to be performed before each shift for cranes in regular service, with the items checked varying between daily and monthly checks.
An operator is conducting a pre-shift inspection and notices that the crane's boom angle indicator is stuck and not moving. What should the operator do?
Answer: Tag the crane out of service until the boom angle indicator is repaired
The boom angle indicator is required safety equipment for proper load chart application. A non-functional boom angle indicator requires removal from service since the operator cannot accurately determine the applicable load chart entry.
