PUSH TO STOP - TWIST TO RESET
Fig 1.10 Launch Chest Pack
The display screen shows a series of illuminated captions with text legends to indicate
which function is in operation at the time and previously selected options (e.g. High
Beam/Level/Low Beam option). The screen is sunlight readable and contains a dimming facility
for night deployments.
Warning lights in the form of monitored indicators, showing critical and non-critical faults,
are also displayed on the screen to prompt the operator to further investigate malfunctions on the
mimic panel within the electrical control cabinet.
The voltage control circuitry provides +/- 10 V dc to the joystick. All other functions are
24 V dc directly powered from the electrical control cabinet.

Two ramp modules and end beams, five parallel modules and 20 approach ramps are pinned and
shoot bolted together to form the bridge span. Two extra ramp modules, two end beams and 20
approach ramps are located on an additional trailer to deploy two 65 ft 6 in (20 m) bridges instead
of one 131 ft (40 m) bridge if required.
