Date Mar. 2, 1995A large manipulator, especially for self-propelled concrete pumps includes a rotary head that rotates about a vertical axis on a mast stand, and a jointed or articulated mast composed of at least three mast arms. The mast arms of the jointed mast can be swivelled to a limited extent about horizontal, mutually parallel axes relative to the adjoining rotary head or mast arm using a corresponding drive unit in each case. The jointed mast is operated by a remote control device which has a signal transmitter situated at the mast top and a control unit. The signal transmitter drives a computerized coordinate field device actuating the drive units according to a displacement path relative to the momentary position of the mast top as directly indicated by means of the control unit.
