National Commission for the Certification of Crane Operators (NCCCO) Mobile Crane Practice Exam

During pick and carry operations, what should be the position of the boom?

1. Keep the boom as short as possible

2. Keep the load as high above the ground as possible

3. Ensure the load is as far from the carrier/carbody as possible

4. Use maximum boom length

The correct answer is: Keep the boom as short as possible

During pick and carry operations, keeping the boom as short as possible is crucial for maintaining stability and safety. A shorter boom length minimizes the crane's center of gravity and increases resistance to tipping, which is essential during the lateral movements associated with pick and carry tasks. When the boom is short, the crane can maintain better control and stability, reducing the risk of accidents or load swings that might occur when the boom is extended. The other options could lead to unsafe operating conditions. For example, raising the load high above the ground can create a higher center of gravity, increasing the risk of tipping. Positioning the load far from the carrier can lead to instability, and utilizing maximum boom length may compromise the crane’s ability to handle the load safely, especially when moving it laterally. Therefore, ensuring the boom remains as short as possible enhances safety and effectiveness in pick and carry operations.
