d. Loading/Unloading the Scissored Bridge to/from a Lowbed Semitrailer using a Second
Launched Bridge as a Ramp - CONT
3 Lift up on lever #4 to retract the locking plugs. Return lever #4 to the neutral position, Return
engine RPM to idle.
NOTE
If problems exist performing step (4) below, go to step (5).
4 Cycle levers #l thru #5 to reduce all hydraulic system pressure. Bridge hydraulic fluid supply
line quick-disconnects should disconnect from bridge. Back launcher away from bridge.
Bridge is now laid.
CAUTION
The ejection cylinder pushes the tongue from the bridge releasing the bridge. Caution
must be used to avoid the premature release of the bridge when in other than a laid
position. As a safety measure, the bridge ejection cylinder will not operate alone, but
must be operated with the locking cylinder control,
5 If the launcher does not release from the bridge easily, the ejection cylinder will have to be
used. Engage the hydraulic clutch pump lever #7. Lift up on lever #4 and hold in position
6 With the locking control lever still in the launching (up) position, lift lever #5 to the launching
position and hold there until the launcher is pushed free of the bridge.
7 To retract the ejection cylinder pins, lift lever #4, and hold in the launching (up) position. At
the same time, hold lever #5 in the down position until the ejection cylinder pins are retracted
8 After the launcher has been disengaged from the bridge, cycle levers #1 through #5 to reduce
hydraulic line pressure. Raise the tongue by holding down on the tongue cylinder lever #2 and
back the launcher away.
(o) Remove the chain holding the loaded bridge's tierod ends together and stow on the launcher
(p) Remove all wood timbers from second bridge and stow as appropriate
(q) Tiedown the loaded bridge to the trailer for transport as shown below paragraph 2-10b(2)(o)
(2) Unloading. Unloading the bridge from the lowbed semitrailer is essentially the reverse procedure
of loading.
