Mobile support assembly with crawler unit, in particular for breaking edge support

摘要

The mobile support assembly according to the invention with a crawler unit has three hydraulic props (4, 5) which are supported on a base plate (1) in foot joints (6) and carry a common roof bar (8) in head joints (7). On both sides of the rear individual prop (5), an individual lemniscate guide-bar system (9) is in each case connected between base frame (1) and roof bar (8). The individual lemniscate guide-bar system (9) is preferably connected to the roof bar via a universal joint (15), if need be in an elastically yielding manner in the direction of the thrust forces acting on the roof bar. The three props (4, 5) are conveniently at least approximately perpendicular to the seam between base frame and roof bar. <IMAGE>
