Which term describes a crane with rotating controls?

• A. Swing Cab
• B. Fixed Cab
• C. Circle Cab
• D. Spin Cab

Answer: (A)

Rotating controls are provided when the operator’s cab is mounted to rotate with the crane’s slewing motion. This is what a swing cab does—the cab is attached to the crane’s turntable and rotates as the upper structure turns, keeping the operator oriented with the load path and controls as the crane moves. This arrangement improves visibility and control during rotations and when sweeping through different directions.

A fixed cab does not rotate, so it wouldn’t have rotating controls. The other two terms aren’t standard industry names for this feature and don’t specifically describe a cab that rotates with the crane, so they don’t fit as precisely.
