Abstract

The invention relates to a large manipulator, especially for truck mounted concrete pumps. A chassis bears a mast base rotatable about a vertical pivot and an articulated mast consisting of at least three arms. The arms can be pivoted to a limited extent about horizontal, mutually parallel axes in pairs in relation to the adjacent base or arm by means of a drive system. The articulated mast is actuated via a remote control device with control levers. In order to ensure a clear allocation of the movements of the control lever and the articulated mast, the invention proposes that the remote control device have a computer-supported co-ordinate transmitter controllable via the control lever for the drive systems via which, in one path of adjustment of the control lever, the drive systems for the pivots can be actuated independently of the drive system for the pivot of the mast base with the accomplishment of an extending or retracting movement of the articulated mast for a predetermined height of the tip of the mast. In the other path of adjustment of the control lever perpendicular to the first path, a rotary movement of the articulated mast about the pivot is triggered via the co-ordinate transmitter independently of the movement in the axes with a predetermined height of the tip of the articulated mast.
