    • 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).
    • 具有多部分旋转框架的转台,动臂或类似物的调平装置(10),其一部分由基座(14)形成,其通过第一转台(20)安装在下部结构 ),其可以通过附接到下部结构的旋转驱动器(26)围绕竖直轴线旋转,以及由支撑梯子或类似物的上部结构(12)形成的另一部分,其与底座(14)连接 这样一种方式使得其可以围绕相对于直立轴线倾斜的连接轴线枢转,所述上部结构(12)可通过枢轴驱动相对于基座(14)枢转,其特征在于,底座(14)具有 大致楔形横截面,并且在该上部结构(12)中通过位于相对于第一转台倾斜的平面(E 1)中的第二转台(32)安装在基座(14)上 20)。
