Emergency Controls
5.1
GENERAL
CHECKING THE OPERATION OF THE EMERGENCY CONTROLS EVERY DAY
AND/OR BEFORE EACH SHIFT IS AN ESSENTIAL PART OF THE OPERATOR'S
DUTIES
The operator and all ground personnel must be thoroughly familiar with the location and operation of
the emergency controls.
5.2
IN THE EVENT OF AN INCAPACITATED OPERATOR
Turn the key switch at the ground control station to
ground
(central position).
Manoeuvre the machine using the ground controls as described previously in Section 4.2.
5.3
IN THE EVENT OF MACHINE FAILURE
If all machine power is lost, the
manual hand pump
can be used to provide the hydraulic power to
manoeuvre the machine. If initial movement of the machine allows the master alarm to reset, normal
controls will be available. This is then the fastest method of lowering the platform to the ground.
Note:
If the machine is fitted with a cage overload system, and the cage comes into contact with a
fixed object whilst operating at height, this would be detected as an overload condition. All power to
the machine controls would be lost, requiring the machine to be recovered using the
Manual Hand
Pump
or
Auxiliary Descent Pump
. It is sufficient for the cage to be manoeuvred away from the
collision point to re-set the cage weigh mechanism, thereby restoring normal machine operation. The
cage can now be lowered using the controls as described previously in Section 4.3.
FOLLOWING AN EMERGENCY DESCENT RECOVERY OF THE PLATFORM, FULLY
EXTEND AND RETRACT ALL CYLINDERS FROM GROUND CONTROL STATION
BEFORE USING THE MACHINE.
5.4
INCIDENT NOTIFICATION
It is a mandatory requirement that any accident or incident involving a Niftylift, regardless of whether
any party received injury or property was damaged is reported by telephone directly to Niftylift. Failure
to do so may render any warranty on the machine void.
