Section III. PRINCIPLES OF OPERATION

1-12 INTERFACE OF COMPONENTS

This section describes how the major DSB components work and interface with each other.

The deployment of the DSB works on a cantilever principle. A launch beam is constructed

and deployed through the launch frame to span the area to be bridged; a far bank support

provides stability and support for the end of the launch beam on the far bank of the launch site.

Fig 1.14 Launch Beam Deployment

A bridge is then constructed and deployed through the A-Frame, the bridge is suspended

from the launch beam by slings from the forward and rear carriages.

Fig 1.15 Bridge Module Deployment

When the bridge construction is complete the bridge is lowered to the ground across the

gap, the launch beam recovered and approach ramps positioned to allow access to traffic. The

launcher vehicle stowed and then removed.
