Two tilt rollers are used to orientate the bridge so that it is parallel to the launch beam
during bridging operations. They are extended/retracted by hydraulic cylinders fitted
inside the main body of the tilt roller. This operation is controlled via the chestpack.
Figure 2. 11 Tilt Roller Deployed
The launch beam, when deployed, provides support for the home and far bank
carriages from which the bridge is suspended during bridge construction. It
comprises eight launch beam modules, which connect together to form the launch
beam. Seven identical beams are transported to the bridging site on a PLS flatrack
carried on an M1076 PLS trailer. The forward launch beam is permanently carried in
the launch frame of the launch vehicle.
The connection systems at either end of the beams are identical and consist of an
upper and lower six lug jaw system.
