An extendable folding boom includes a turntable rotatable about a vertical axis, a plurality of boom segments pivotable at folding joints about respectively horizontal folding axes with respect to an adjacent boom segment or the turntable, and a sensor configured to sense a folding angle between two adjacent boom segments or between a boom segment and the turntable. The sensor includes a field-generating element and a field-sensing element spaced apart from each other along a horizontal axis in a contactless arrangement.
