10 Emergency Operations
10.1 Recovery Options
The normal method of recovery is available when the machine engine is driving the hydraulic pump
and the cab controls are available. Follow the instructions in this manual for normal operations,
detailed depending upon which mode of operation is being used.
If the electrical systems have failed, or the engine has failed (e.g. run out of fuel) then the boom may
only be returned to its stowed position using the Battery Driven Pump.
There are 2 methods of emergency recovery of the machine both of which use the cab controls. In
order of preference these are:
Machine Engine
Battery Driven Pump.
To use these systems, the safety systems must be overridden using the RCI Over-ride key switch in
the engine bay.
10.1.1 Machine Engine
Using the cab controls:
Operate the RCI Over-ride key switch.
Utilise the Machine Engine.
10.1.2 Battery Driven Pump
Where the machine engine has failed using the cab controls:
Operate the motion cut over-ride latches.
Utilise the Battery Powered Pump.
10.1.3 Manual Over-ride Latches
In the event of an emergency, loss of power or RCI system failure an over-ride is fitted to this machine
to enable the booms to be slewed, retracted and lowered to their stowed positions. This is used in
conjunction with various power sources and control mechanisms as detailed above.
The over-ride key is located in the Engine Bay.
Ensure that all personnel, either operating or working alongside this machine, are aware of the
location and operation of each of these systems.
THESE OVER-RIDE FEATURES MUST ONLY BE EMPLOYED IN THE
EVENT OF AN EMERGENCY, LOSS OF POWER OR RCI FAILURE. THEY
ARE NOT CONSIDERED SUITABLE FOR NORMAL USE.
The over-ride key, when activated, allows the operator to bypass the following safety interlock systems
on the boom:
Over-tilt (cant) in both directions
Motion cuts
Load sensing system
Moment sensing system
Slew restriction.
During an over-ride situation all audible or visual warnings associated with any of the above interlocks
will continue to actuate. An additional buzzer will sound whenever an over-ride is active to indicate that
the over-ride feature is being activated. Once the over-ride system is activated the data logger will
monitor the system.
