Abstract (en)
[origin: WO9506178A1] The invention pertains to a large manipulator, especially for self-propelled concrete pumps. A rotary head (17) that rotates about a vertical axis (18) on a mast stand (16) and a jointed mast (20) composed of at least three mast arms (1 to 5) are mounted on a chassis (10). The mast arms (1 to 5) of the jointed mast (20) can be swivelled to a limited extent about horizontal, mutually parallel joint axes (A to E) relative to the adjoining rotary head (17) or mast arm (20) using a corresponding drive unit (30) in each case. The jointed mast (20) is operated by a remote control device which has a signal transmitter (53) situated at the mast top (55); operated mechanically using a control unit (52), said signal transmitter (53) drives a computerized coordinate field device actuating the drive units (30) of the joint and rotational axes according to a displacement path relative to the momentary position of the mast top (55) as directly indicated by means of the control unit (52).
