d. Loading/Unloading the Scissored Bridge to/from a Lowbed Semitrailer using a Second
Launched Bridge as a Ramp - CONT
Prior to releasing and removing the tiedown chains from the bridge/trailer, the launcher
should be engaged to the bridge on the trailer to prevent the bridge from slipping or
shifting its position.
When releasing the tiedown chain binders use extreme caution to avoid binder handle
backlash which may likely occur.
The vehicle operator should wear protective headgear or close the hatch when recovering
the bridge onto the carrier to prevent injury from falling rocks and debris as the bridge is
brought back into the travel position on the launcher.
(a) With trailer and folded bridge in position at the second (laid) bridge, chock block the rear
duals and apply the tractor parking brakes.
