Special procedure
1 - Emergency lowering
1.1 - PRINCIPLE
N.B. -:-During rescue and emergency maintenance manoeuvres from the ground, it is essential to
ensure that there are no obstacles under the platform (wall, beam, electricity line, etc.).
Emergency lowering is implemented if the operator using the console on the platform needs
to be rescued and cannot operate the controls himself even if the machine is operating
normally. This situation may arise if the operator is taken ill, is injured or if the control console
is inaccessible.
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 ( 16 ) to the right to energize the ground
control box. The platform control box controls are de-energized.
2. Lower the platform from the ground control box.
N.B. -:-Activating the emergency controls listed above deactivates the controls of the console on the
platform.
1.3 - EXTRAORDINARY PROCEDURE
In the context of emergency lowering, it is possible that the emergency stop located on the
platform is activated or that safety mechanisms such as the overload limitor are preventing the
machine from operating normally.
During an exceptional procedure, for machines which are not fitted with the manual rescue
control as described in the "emergency lowering" paragraph, activating the lower console
deactivates the emergency pushbutton located on the platform.
N.B. -:-During these exceptional manoeuvres, movements are slowed down for safety reasons.
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.
