6.5 AERIAL PART EMERGENCY MANOEUVRES
The machine has been designed also considering possible emergency situations such as
mechanical and electrical breakdown, sudden indisposition of the operator etc. In all of these
cases interventions can be made on the machine from the basket and from the ground in a
way to take the machine back to the transport configuration or however into a way to be able
to rescue the occupant/s from the basket. The intervention procedures are given below.
Remember that the presence of staff on the ground is mandatory during platform functio‑
ning.
The manoeuvres described below must be performed in SEQUENCE starting from the
first paragraph and passing to the next ones till the last one only if the emergency
manoeuvre that is being performed is not functioning.
6.5.1 A CTIVATION OF EMERGENCY DESCENT FROM THE BASKET
The emergency descent procedure of the basket can be actuated from the basket itself only if
the machine electric plant is not compromised; act in the following way:
‑ hold down button 4 on the remote control (paragraph 2.1.1 Control position);
‑ check the control by means of icon 8 on the display (paragraph (paragraph 4.2.1 Display
main visualization
);
‑ activate the joystick relative to the arm that is to be closed until the desired height is rea‑
ched (paragraph 4.3 Joystick);
‑ release button 4.
As it is descent due to gravity, the platform and basket cannot be rotated and the telescopic
arm cannot be extended or retracted, therefore the basket descends vertically at a distance
from the centre of rotation that is conditioned by the configuration that the machine had at
the time the emergency situation was created.
If a Joystick relative to a movement without emergency descent is activa‑
ted, an icon error will appear on the display:
The message disappears on release of the Joystick.
