Multiple Choice

Crane with rotating controls ______. Crane with stationary controls _______.

Explanation:
The key idea is how the operator’s cab moves as the crane slews. If the cab (and its controls) rotate with the crane’s upper works, the cab is called a swing cab or rotating cab. If the cab stays facing the same direction while the crane rotates, it’s a fixed cab. So a crane with rotating controls uses a swing cab, and a crane with stationary controls uses a fixed cab. The other terms aren’t the standard way to describe this difference.
