Before moving the bridge, routine PMCS shall be performed. If the bridge is destined for a combat zone

(and time permits) all checks and services should be performed. The bridge can be moved many ways.

The primary mode of transporting the bridge is by launcher.

Make sure hydraulic clutch pump lever #7 is disengaged before movement. Failure to

disengage can cause blown hydraulic lines or seals and other damage.

Movement of AVLB by Launcher Vehicle.

The bridge can be moved to it’s site by the launcher

vehicle. See FIGURE 1-1. Prior to movement, ensure a PMCS has been performed. Ensure the bridge

is properly sedated on the bridge seat by making a visual inspection.
