- Special procedure
Engine-powered articulated lifts, 12 - 26 m
Special procedure
1 - Emergency lowering
1.1 - PRINCIPLE
Emergency lowering is required if the operator in the platform is no longer capable of
controlling the movements even though the machine operates normally.
A ground operator trained in using the emergency controls and in possession of the starter key
can use the ground control box with the main power source to lower the platform operator.
1.2 - PROCEDURE
Section A 2- Pre-operation instructions
1.
Turn the key on the control box activation selector switch ( 72 ) to the right to activate the ground
control box. The platform control box controls are de-activated.
2.
Lower the platform from the ground control box.
2 - Lowering for repairs
2.1 - PRINCIPLE
The lowering for repairs function allows the operator in the platform to descend again in case
of failure of the main power source.
The electric pump, powered by the starting battery, allows movements to be controlled from
both the ground and platform control boxes.
As the electric pump only has limited autonomy, it is advisable to come back to the ground in
the most direct manner possible.
2.2 - PROCEDURE
For : HA120PX (NA) (Back-up unit option) - HA16X (NA) - HA16SPX (HA46SJRT) - HA16PX
(HA46JRT) - HA18SPX (HA51SJRT) - HA18PX (HA51JRT) - HA20PX (HA61JRT) -
HA260PX (HA80JRT) :
Depending on the control box used, push and hold the back-up hydraulic power system
selector switch ( (19) downwards or (41) upwards) and lower the platform.
For HA120PX only :
There is a way of performing movements from the ground, when the main energy source
malfunctions. It is a hand pump located next to the hydraulic distributors on the turntable.
Find all the function indicators and controls in
Section C 5 - Control boxes
If the machine is stuck or hooked in surrounding structures or equipment, it is essential to release the
operators before intervening on the machine.
The use of the electric pump is exclusively reserved for the lowering for repairs function.
Performing other operations can lead to the deterioration of the electric pump.
