When given the signal for bridge travel, what action should the crane operator perform?

• A. Trolley travel
• B. Raise the load
• C. Lower the load
• D. Bridge travel

Answer: (D)

The signal for bridge travel means moving the entire crane bridge along the runway to reach a new position. When you see that signal, you operate the bridge controls to shift the bridge horizontally in the requested direction, keeping the area clear and the load secured. This is different from trolley travel, which moves just the hoist trolley along the bridge, and from raising or lowering, which operate the hoist to change the load height. So the action to take is to move the bridge along the runway.
