NCCCO Pick and Carry Operations 5

Question 1

An operator notices the crane's load moment indicator (LMI) alarm activating during pick and carry travel. The correct response is to:

Accepted Answer

Stop travel immediately, set the brake, and evaluate the load and conditions

Answer

An LMI alarm is a warning that capacity limits are being approached or exceeded; the operator must stop and assess immediately.

Question 2

Which of the following is an acceptable practice when a tag line is used during pick and carry operations?

Accepted Answer

The tag line is used to prevent load rotation and swing, held by a worker walking at a safe distance to the side

Answer

Tag lines control load rotation and swing; handlers must maintain safe positioning to the side and never in front of or under the load.

Question 3

A crane manufacturer's pick and carry load chart lists a reduced capacity when traveling with the boom 'over rear.' This is primarily because:

Accepted Answer

The counterweight is at the rear, reducing its stabilizing effect when the load is also at the rear

Answer

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.

Question 4

During pick and carry operations, wind speed becomes especially critical because:

Accepted Answer

Wind force on a suspended load increases the effective load radius and overturning moment

Answer

Wind pressure on the load creates a lateral force that adds to the overturning moment, effectively increasing the load radius beyond chart assumptions.

Question 5

What is the purpose of a pre-travel path inspection before a pick and carry operation?

Accepted Answer

To identify ground conditions, overhead hazards, grades, and obstacles that could affect crane stability or clearance

Answer

A path inspection identifies all hazards along the route—soft ground, slopes, overhead lines, holes—that could compromise safety during the move.
