4.5 - EMERGENCY DESCENT
Photo 10
There may be cases where the operator in the platform is no longer able to
control its movement, even through the machine is functioning normally. An
able-bodied operator on the ground can use the "turret" lectern with main
diesel power source to retrieve the operator on the platform.
Procedure :
• Switch the driving position selector key (rep. 1, Photo 10) to the "tur-
ret" position (orange circle). In this position the controls in the "plat-
form" lectern are disabled.
• Carry out the desired movements using the controls as you would nor-
mally.
4.6 - BREAKDOWN DESCENT
Use of the emergency set is only for
the rescue of personnel if there is a
breakdown in the main power
supply. Any other usage many
cause damage to it.
4.6.1 - Breakdown rescue with the emergency electro-
pump set
There is a way to carry out movements when there is a malfunction of the
main power source. This is the electro-pump set power by the starter
battery. This can be controlled equally from the turret lectern or the platform
lectern.
Operating time using the emergency set is limited, so you are advised to
return to the ground by the most direct means possible (see drawing).
If an operator at height must
abandon the platform for a solid and
safe structure, the transfer should
only be done with the following
recommendations: - The operator
must secure himself using 2 belts. -
One belt must be fastened to the
platform, the other to the structure.
- The operator must only leave the
platform through the access
trapdoor. - The operator must not
unfasten the belt fastened to the
platform before the transfer is
completed, or if there is still a risk of
danger.
• Procedure :
• Using the selected control position, press and hold down the emer-
gency control positioning interrupter (control rep 17, Photo 1, page 27
and control rep 11, Photo 2, page 28).
- If required, move away from obstacles using platform and direction
movements.
• Press and hold down the interrupters for the movements required in
the following order:
- Partially retract the telescopic arm and fly jib (so that no red area
is visible on the side),
- Lower the fly jib fully,
- Lower the arm to return the platform to the ground
