Mobile powered support assembly |
摘要 |
The mobile powered support assembly according to the invention, provided with a crawler unit (1), has a base frame (5) which is arranged between the two crawler tracks (2) of the crawler unit and on which the props (7) are supported in an articulated manner. The base frame (5) is connected to the crawler tracks (2) via lifting cylinders (20) in such a way that it can perform lifting and angular movements. The prop forces can therefore be passed directly to the floor via the base frame (5). In addition, a lemniscate mechanism (10) is conveniently provided between the base frame (5) and the common canopy bar (9). The lemniscate mechanism (10) is connected to the canopy bar via a universal joint (17) or the like. <IMAGE>
