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.
3.9.10.25 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 slings are lightly
tensioned.
3.9.10.26 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, it is permissible to have
personnel on the bridge to one side or other of the centerline to assist in balancing the bridge.
3.9.10.27 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.
3.9.10.28 On the chest pack, move the joystick to the left to select the BRIDGE DRIVE function.
3.9.10.29 Make sure the POWER and the BRIDGE DRIVE mode previously selected captions
(LEVEL, HIGH or LOW) on the chest pack display, illuminate. DO NOT OPERATE IN
EMPTY CARRIAGE MODE.
