The invention relates to a mobile large manipulator (10), comprising a chassis (12), two front support arms (14) and two rear support arms (16) that can be supported on a base surface by way of extendable support legs. The respective support arms are arranged on the chassis (12), and can be extended, entirely or in part, from a travel position to a support position. The invention further comprises a foldout mast arm (18) provided with a swiveling bolster (20) rotatably arranged on the chassis about a vertical axis and a plurality of mast segments that are hingedly connected to one another, wherein the operating range (60) of the mast arm (18) is dependent upon the support configuration, that is, dependent upon the support positions of the support arm. The large manipulator (10) is characterized by a program-controlled positioning aid, configured for outputting a graphical representation of ambient image data on a screen (42), wherein the operating range (60) of the mast arm (18) is visualized in the graphical representation. The invention further relates to a method for program-controlled assistance with positioning and/or supporting a large manipulator (10). |
