Boom height represents...

Boom height represents...

• A. The vertical distance from the ground to the center of gravity of the load.
• B. The horizontal distance from the crane base to the boom tip.
• C. The vertical distance from the ground to the center of the boom.
• D. The vertical distance from the ground to the top of an elevated boom.

Answer: (D)

Boom height is the vertical distance from the ground to the top of the crane’s elevated boom. This measure tells you how high the boom reaches, which affects clearance, overhead obstructions, and safe operation when lifting or moving loads. The correct concept captures the height of the boom itself, not the load or other distances. For example, vertical distance to the load’s center of gravity describes how high the load sits, not how high the boom is; horizontal distance to the boom tip refers to reach, not height; and vertical distance to the center of the boom isn’t a standard height measurement.
