ABSTRACT:
Movable ground supports, which are folded out either manually or hydraulically, are arranged at the tip of the launching support in devices for laying collapsible bridges. An inflatable container (6) is integrated in the structural part (2) of the launching support (8), and the container acts as a movable support in the filled state. A release mechanism (10) arranged in the vicinity of the container ensures that the medium--compressed air or nitrogen--will escape from the inflated container (6) when the end of the bridge (5) has completely reached the bearing (9) after advancing forward.
