Abstract
The invention relates to a large manipulator (1), in particular a truck-mounted concrete pump, having a mast pedestal (3) which is rotatable about a vertical axis by means of a rotary drive and which is arranged on a chassis (2), having an articulated mast (4) which comprises two or more mast arms (5, 6, 7, 8), wherein the mast arms (5, 6, 7, 8) are connected, so as to be pivotable by means of in each case one pivoting drive, to the respectively adjacent mast pedestal (3) or mast arm (5, 6, 7, 8), having a control device, which actuates the drives, for the mast movement, and having a mast sensor arrangement for detecting the position of at least one point of the articulated mast (4) or a pivot angle (φ1, φ2, φ3, φ4) of at least one articulated joint. The large manipulator is characterized in that the control device (17) is designed to limit the speed of the mast movement on the basis of the output signal from the mast sensor arrangement. The invention also relates to a method for controlling the movement of an articulated mast (4) of a large manipulator (1), in particular of a truck-mounted concrete pump.
