Abstract (en)

Turntable ladder, telescopic mast platform or similar, with a telescoping ladder set (5) or telescopic mast, and possibly, a passenger cage (3) attached thereto, said turntable ladder or telescopic mast comprising a control for the movement of the ladder parts or telescopic mast parts, which is contrived in such a way that when the turntable ladder or telescopic mast platform is operated, oscillations in the ladder parts or telescopic mast parts are suppressed in that at least one of the measured values, i.e. bending of the ladder set or telescopic mast in the horizontal or vertical directions, erection angle, angle of rotation, extension length and torsion of the ladder set or telescopic mast, is fed back via a controller to the control values for the drives, characterised in that attached to the ladder set or telescopic mast and/or to the passenger cage there are inertial sensors for detecting the bending state of the ladder set or telescopic mast.
