Which crane design allows the control station to move with the boom?

• A. Swing cab (rotating controls)
• B. Fixed cab
• C. Remote control
• D. Stationary cab

Answer: (A)

A swing cab is designed so the cab and its controls rotate with the crane as the boom moves, keeping the operator facing the load and in line with the direction of travel. This setup lets the control station move with the boom, maintaining orientation and visibility during slewing and extension, which improves control accuracy and safety. In contrast, a fixed or stationary cab doesn't rotate with the boom, so the operator would have to twist or readjust to keep seeing and guiding the load. Remote control places the operator away from the cab, with no moving control station tied to the boom, so it also doesn’t move with the boom.
