Launched Bridge as a Ramp - CONT
4 Lower the base of the outrigger firmly on the timbers. Be sure that the bridge, when laid, will
align with the bed of the trailer.
Working on, around, or under a suspended bridge is dangerous. Bridge may fall due to
a failure in the hydraulics or a mechanical break. Never turn your back on a suspended
bridge. Keep an orderly work area and stay free of tangled cables, chains, etc. In case of
a failure, immediately exit the work area opposite the direction of the falling bridge.
5 Continue to maintain lifting pressure on
lever #1 until the bridge has raised to the
upright position and rotated slightly past
vertical. The outrigger should be resting
on the wood blocks at this point.
6 Release the launcher brakes slowly while
keeping pressure on the brake pedal.
Allow the launcher to slowly crawl
forward until the out-rigger boom pads
firmly contact the launcher. Return lever
#1 to the neutral position.
7 Depress the brake pedal and move the
transmission shift lever #6 to "P" to
engage the parking brake.
