An operator notices the crane's load moment indicator (LMI) alarm activating during pick and carry travel. The correct response is to:
Answer: Stop travel immediately, set the brake, and evaluate the load and conditions
An LMI alarm is a warning that capacity limits are being approached or exceeded; the operator must stop and assess immediately.
Which of the following is an acceptable practice when a tag line is used during pick and carry operations?
Answer: The tag line is used to prevent load rotation and swing, held by a worker walking at a safe distance to the side
Tag lines control load rotation and swing; handlers must maintain safe positioning to the side and never in front of or under the load.
A crane manufacturer's pick and carry load chart lists a reduced capacity when traveling with the boom 'over rear.' This is primarily because:
Answer: The counterweight is at the rear, reducing its stabilizing effect when the load is also at the rear
With the boom over the rear, both the load and counterweight are on the same side, reducing the counterweight's ability to offset the load moment.
During pick and carry operations, wind speed becomes especially critical because:
Answer: Wind force on a suspended load increases the effective load radius and overturning moment
Wind pressure on the load creates a lateral force that adds to the overturning moment, effectively increasing the load radius beyond chart assumptions.
What is the purpose of a pre-travel path inspection before a pick and carry operation?
Answer: To identify ground conditions, overhead hazards, grades, and obstacles that could affect crane stability or clearance
A path inspection identifies all hazards along the route—soft ground, slopes, overhead lines, holes—that could compromise safety during the move.
When a pick and carry operation requires travel on a public road, the operator must ensure:
Answer: All applicable highway transport permits, police escorts, and legal configurations are in place
Public road travel with a crane load requires proper permits, may require police escort, and must meet legal transport requirements for width, weight, and height.
When setting down a load at the end of a pick and carry operation, the operator should:
Answer: Come to a complete stop, stabilize the crane, then lower the load in a controlled manner
Stopping completely and stabilizing before lowering eliminates dynamic forces and allows for precise, controlled load placement.
