A contractor determined that transporting a crawler crane under its own power would cause no damage to a highway surface. The gantry was lowered to clear overhead wires. The contractor proceeded:

• A. Incorrectly
• B. Correctly
• C. Not enough information
• D. Possibly unsafe

Answer: (B)

Before moving a crawler crane on a highway, it’s essential to verify that the action won’t damage the road and that any overhead obstacles can be cleared safely. In this case, the contractor checked that transporting the crane under its own power would not harm the pavement, and they lowered the gantry to pass under overhead wires. Those steps show a careful preparation to avoid road damage and to ensure sufficient clearance, which supports proceeding with the move in a controlled, safe manner. In practice you’d also consider route planning, permits, and traffic control, but with the information given, moving under its own power after confirming no pavement damage and adjusting for clearance is the correct course.
