NOTE
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 home bank carriage beam and the bridge until the slings
are lightly tensioned.
5.4.1.28
Adjust home bank carriage slings to ensure evenly distributed loads through both left
and right slings.
NOTE
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.
5.4.1.29
Continue to slowly raise the home bank carriage and the bridge, until the shootbolts
in the far bank carriage beam can be inserted to reconnect the two halves.
NOTE
Ensure that the lower section of the home bank carriage is correctly aligned with the
upper section of the home bank carriage. Personnel should use the lifting slings to assist
in aligning the two halves of the far bank carriage.

EMPTY CARRIAGE MODE.
5.4.1.32
On the chest pack, move the joystick rearward to reverse the bridge towards the
launch vehicle. Release the joystick when the home bank carriage is fully retracted
and the restraint latches engage locking the home bank carriage to the launch
frame.
