Send two personnel to the far bank to assist the far bank carriage in lowering.
Position one man by the far bank carriage ready to pull on the lower half of the carriage.
Position one man at the mid way point of the bridge ready to pull on the wire winch rope.
126.96.36.199 On the chest pack, move the joystick forward to raise the far bank carriage so that the
shootbolts can be retracted.
Continuing to operate bridge lift will create a build up of tension in the lower winch cable,
which could cause the cable to nest on the winch drum.
188.8.131.52 Retract the shootbolts on the far bank carriage.
PERSONAL INJURY. WHEN HANDLING WINCH CABLE, USE THICK LEATHER GLOVES TO
PREVENT INJURY TO HANDS FROM BROKEN STRANDS.
Equipment damage. Failure to adhere to the procedure below will allow the rope to double
wrap (nest) on the winch drum.
184.108.40.206 To allow the far bank carriage slings to go slack, perform the following:
220.127.116.11 One of the two far bank operatives stands at the center of the bridge.
18.104.22.168 Operate the lower winch to pay out the rope.
22.214.171.124 Just prior to the slack rope touching the center of the bridge, the first operative grabs hold
of the rope and pulls it towards the far bank. This allows the second operative to pull down
on the far bank carriage and thus slacken the slings.
126.96.36.199 It is important to pull on the rope in a continuous motion as the winch is operated, to
prevent the rope from double wrapping on the winch drum.
188.8.131.52 On the chest pack, move the joystick rearward to lower the far bank carriage. Do not
allow the far bank carriage beam to rest on the bridge as this may cause the cables to
184.108.40.206 Route the far bank carriage slings through the far bank ramp end beam lifting points
(Figure 3. 38) and reconnect
to the carriage beam. Ensure that the sling straps
cross and are not twisted. Ensure that the carriage is level horizontally and vertically prior
to lifting, with respect to the upper part of the carriage.
