Abstract (en)
[origin: EP2177709A1] Levelling device (10) for a turntable ladder, a boom or similar, with a multi-part rotating frame, one part of which is formed by a base (14), which is mounted on an understructure by means of a first turntable (20), which can be rotated around an upright axis by means of a rotary drive (26) attached to the understructure, and a further part formed by a superstructure (12) supporting the ladder or similar, which is connected with base (14) in such a manner that it can be pivoted around a connecting axis which is inclined relative to the upright axis, said superstructure (12) being pivotable relative to base (14) by means of a pivot drive, characterised in that base (14) has an approximately wedge-shaped cross-section, and in that superstructure (12) is mounted on base (14) by means of a second turntable (32), which lies in a plane (E 1 ) that is inclined relative to the first turntable (20).
