After a crawler crane has been delivered and is on the ground, the first step is to:

• A. Erect the gantry in the high position
• B. Inspect the hoist
• C. Install outriggers
• D. Stabilize base

Answer: (A)

When setting up a crawler crane, you want the crane’s main frame to be in its proper operating geometry before any other tasks. Erecting the gantry to the high position does exactly that: it brings the crane into its full, intended structure, providing the correct clearance, alignment, and access for the rest of the setup. With the gantry in the high position, you can safely inspect components, position and install outriggers, and stabilize the base in the correct geometry. Skipping this step or delaying it can lead to interference, misalignment, or instability as you try to perform other setup tasks. So raising the gantry first establishes a safe, proper foundation for all subsequent setup and lifting operations.
