Check
the
bridge
stop
emergency
handle
and
shaft
for
deformation/obstruction. Report deformation to maintenance.
Check the V notch in A-frame side rubbing pad for wear limit. Report wear to
maintenance.
Tilt roller will not raise.
Is a BRIDGE DRIVE mode selected on the chest pack?
Is the tilt roller light flashing on the chest pack? If YES, switch the roller
brakes to on.
Is the bridge boomed so that the white marker on the bridge module is in line
with inside face of A-frame? If YES, continue to next sequence. If NO,
operate the chest pack right hand joystick to boom the bridge so that the
white marker on the bridge module is inline with inside face of A-frame. If tilt
roller still does not raise continue to next sequence.
WARNING
CRUSH HAZARD. DO NOT EXCEED 6 INCHES WHEN BOOMING THE BRIDGE.
THE BRIDGE MAY TIP INJURING PERSONNEL.
♦ Boom the bridge up to 6 inches further forward.
Check hydraulic and electrical systems are working correctly, report any
defect to maintenance.
Check the tilt roller assembly for deformation/obstruction. Report any
deformation to maintenance.
Roller brakes do not work.
Is roller brake switch on the chest pack set to the ON position (switch is
located at lower right hand side of chest pack)?
Check roller brakes for class III hydraulic leaks. Report any leaks to
maintenance (Tighten joints. Re-seal motor or replace as required).
Check hydraulic and electrical systems are working correctly, report any
defect to maintenance.
Rollers not damped.
Check for any hydraulic oil leaks around motor/roller housings. Report any
leaks to maintenance (re-seal or replace motor/roller housings as required).
57. Continue boom using tilt rollers and lower bridge stops emergency.
See Operation 55 and 56.
58. Add second parallel module. (This procedure is slightly different from
RAMP to PARALLEL.
Parallel module does not open, open fully or open evenly.
Check that the module lifting beam is in the correct configuration for opening
and all arms are shootbolted.
Check that all deck units align with the machined slot on the parallel panels.
♦ Refold the parallel module and check for correct positioning of deck
spacers. Refer to Chapter 10 maintenance procedure 10.4.
♦ Refold the parallel module and check for correct thickness of deck
spacers. Refer to Chapter 10 maintenance procedure 10.4.
Support the partially opened parallel module; check the dampers on the non-
open side for free play. The damper with no free play will be the defective
unit. Report defective damper to maintenance.
Module will not connect.
Dowels will not connect.
Ensure that all the shootbolts on both modules are fully lowered. Connect
dowels and shootbolt.
