ABSTRACT:
The invention concerns a bridging system comprising several uniform bridge section in the form of track supports (1). The width of the bridge can be continuously adjusted with telescoping pipes ( 2 ). The stationary ramps ( 3 ) on the track support are slotted like a comb and, once the have been assembled and connected to the pivoted-out lower truss system (4), can accommodate any compression forces and bending moments that occur when traveled. Since each track support is the same shape, the bridging system has a smoothly curving upper roadway edge.
The traction component (5) in each track support travels back and forth between pivoting stays (9) provided with connectors (8) and the overall lower truss system can be pivoted into the track support.
This bridging system, which consists of modular track supports (1), is outstanding for its compact traveling state and few connectors and can be positioned by appropriate transporting and laying equipment.
