12.5.11 Run Recovery
Figure 19 - Run Recovery Page
The “Run Recovery” page of the main menu will display the page shown above. This screen allows
operation of the recovery pump to assist in the rescue of the machine from whatever position it
requires recovery from. To run the pump, press and hold the F1 key, noting the status of the system
as it is operated. There are three pumps that will operate while the key is pressed, activating in 1
second intervals from pilot pump, to main pump, to secondary main pump. The status of rail axle
movement availability is also given.
12.5.12 Emergency Recovery
If the machine breaks down in such a position that it is likely to obstruct an adjacent line or cause an
accident or damage to the railway infrastructure or any other vehicle, it is important that the machine is
placed in a safe position as soon as possible. For this reason the excavator has been fitted with an
electro-hydraulic power system and tow bar by which another machine can tow it to safety.
Instructions on how the auxiliary system works are described below. Read and understand these
instructions so that in the event of a machine failure you the machine can be out in a safe position:
Slew the machine so that the arm is parallel to and clear of any adjacent line with the
counterweight facing the vehicle that is to be used for towing.
Lower the boom so that the highest point is no higher than the top of the cab.
Connect the failed machine and recovery vehicle together with the approved tow bar.
Release the axle lock stabilisers of the failed machine.
ONLY RELEASE THE FINAL DRIVE SHAFT SPLINES ON THE FAILED MACHINE ONCE
THE TOW BAR HAS BEEN CONNECTED TO THE RECOVERY VEHICLE OTHERWISE
THE MACHINE MIGHT RUN AWAY.
Ensure that towing is carried out at approximately 2 mph as the recovery vehicle has to brake
for both vehicles and at a higher speed braking distance would be greatly increased.
Switch on machine ignition switch.
Switch Prolec on and place in override for duration of the recovery. (if Prolec lift watch RCI is
fitted)
When the recovery pump is running the auxiliary valve block on the machine is operational
this provides the following essential functions for recovery:
Raise and lower of main arm lift ram;
Slew left and right;
Arm knuckle left and right;
Raise front rail gear/blade trolley;
Raise the rear rail gear.
Operate the machine controls in the usual way to bring the machine into travel gauge to
prepare for towing.
