2.9.8 MANOEUVRING THE BASKET EMERGENCY DESCENT
The machine has been planned considering any possible emergency situations such as
mechanical breakdowns, electric breakdowns, the operator’s sudden illness etc.). In these
cases it is possible to intervene on the machine both from the basket and the ground place in
order to bring back the machine to transport configuration or anyhow to bring assistance to
the occupant(s) of the control car. You will find below the intervention procedures.
Remember that it is mandatory to have staff on the ground when the platform is working.
2.9.8.1 ACTIVATING THE BASKET EMERGENCY DESCENT
The emergency descent of the control car can be activated from the control car itself only if
the machine electric system has not be compromised; to proceed do the following:
‑ Press the manual selector;
‑ Act on the arm descent controls used normally until the desired height;
‑ Release the manual selector.
Being a descent through gravity obviously it is not possible to have a rotation movement
from the platform and to re‑enter or withdraw the telescopic arm. Therefore the basket
descents vertically at a distance from the rotation centre that is conditioned by the configura‑
tion the machine had at the moment of emergency.
During the emergency descent, the jib cylinder cannot be activated. Therefore with the arm
completely lowered, the control car comes to be at 1.80m from the ground. In this case, to
bring assistance to the person on the control car you need to use an external tool (e.g. lad‑
der).
