It is extremely important that the two carriage parts are in line vertically and horizontally.
Failure to ensure correct alignment will result in the bottom half of the carriage becoming
jammed in the top half of the carriage when it is raised.
Make sure personnel are clear of the area. On the chest pack, move the joystick
forward to partially raise the far bank carriage beam and the bridge until slings are
Adjust far bank carriage slings to ensure evenly distributed loads through both left
and right slings. Ensure that the carriage lifting slings are pushed to the outside of
the carriage to assist in a balanced lift. Ensure that lifting slings are not twisted
The bridge may lift out of balance, due to mud or personnel on the bridge. To overcome
this situation lower the bridge and re-sling or ensure that personnel on the bridge are as
close to the centerline as possible. If the bridge still lifts out of balance then it is
permissible to have personnel on the bridge to one side or other of the centerline to assist
in balancing the bridge.
Continue to slowly raise the far bank carriage and the bridge, until the shootbolts in
the far bank carriage beam can be inserted to reconnect the two halves.
Ensure that the lower section of the far bank carriage is correctly aligned with the upper
section of the far bank carriage. Personnel should use the lifting slings to assist in
aligning the two halves of the far bank carriage.
Move the joystick on the chest pack rearwards to release the tension in the lower
winch cable. Tension is sufficiently released when the cable starts to move away
from the underside of the launch beam.
On the chest pack, move the joystick forward to raise the home bank carriage so
that the shootbolts can be retracted.
Retract the shootbolts on the home bank carriage.
On the chest pack, move the joystick rearward to lower home bank carriage. Do not
allow the beam to rest on the bridge as this may cause the cables to become
Route the carriage slings through the front ramp module bridge lifting points (Figure
5. 2) and re-connect the sling
to the carriage. Ensure the slings
do not cross and
thus become twisted. Ensure that the carriage is level horizontally and vertically,
prior to lifting, with respect to the upper part of the carriage.
