Abstract: A mobile large manipulator includes a chassis, unfoldable and/or extendable working boom, supporting struts, vertically extendable supporting legs, and a micro-controller-based program-controlled supporting aid. The unfoldable and/or extendable working boom is arranged rotatably around a vertical axis on the chassis. The supporting struts are respectively arranged on the chassis and are horizontally extendable from a travel position to a supporting position. The vertically extendable supporting legs are arranged on respective outer ends of the supporting struts. The supporting legs support the mobile large manipulator via respective supporting forces of the supporting legs. The supporting aid is configured to determine supporting forces for the respective supporting legs based, at least in part, on the supporting position of the supporting struts in which the chassis of the large manipulator is deployed unstressed in a support state.

Abstract: 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.

Abstract: A support apparatus for coupling to a vehicle, the apparatus including a support structure and a hydraulic cylinder coupled to the support structure. The hydraulic cylinder is configured to move linearly with respect to the support structure and to expand and contract. The apparatus further includes a sensing assembly that includes a proximity sensor. The proximity sensor is configured to sense and indicate that the hydraulic cylinder breaches a predetermined threshold distance between the hydraulic cylinder and the support structure.
