Which term refers to the rotating platform that supports the boom and counterweight assembly?

Explanation:
The rotating platform is called the turntable. It sits on the base and provides the bearing surface that lets the upper works—the boom and its counterweight—slew around a vertical axis. This rotation is essential for positioning loads in different directions while the base remains stationary. The base is the fixed foundation, the mast is the vertical support, and the frame is the static structural assembly.
