4.2 - TO RESCUE OPERATOR IN PLATFORM
In a situation where an operator located in the platform needs to be rescued (for example in
case of illness, injury or trapped against a structure making the control box inaccessible), the
rescue personel at ground level needs to obtain rapid and direct access to operating functions.
HAULOTTE® provides a ground control emergency system that should be used to safely bring
the operator into such a position that appropriate medical attention could be provided.
Unlike the ground control box used in lowering the boom, the overriding system allows trapped
occupant(s) be lowered to the ground level, even if an E-Stop is engaged or if an overload is
detected.
In this situation, supervisor(s) at ground level must turn the control box selector ( 72 ) to the
"right" on the ground control box to take control. To safely activate movements from the ground
control box, the enable switch ( 228 ) must be held activated/depressed.
Procedure :
• Turn the control box selector ( 72 ) to the "right" to energize the ground control box.
• The platform box controls are now de-energized.
• Check that the E-Stop button ( 15 ) at ground is not pressed in.
• To lower the platform, hold enable switch ( 228 ) downwards and simultaneously push the desired
function switch.
• If the E-stop button ( 15 ) or a safety device do not allow normal movement from the ground control
box, the overriding system is operated as follows :
• Operate the "overriding system" switch ( 245 ) on the ground control box.
• Simultaneously, push upwards and maintain overriding switch ( 245 ) in addition to desired movements
actuator to obtain movement of the extending structure.
N.B.-:-Operationofthe"overridingsystem"switchmustbeanexceptionandnotanormalemergency
operation.
ONLY in these conditions, activate the "overriding system" switch ( 245 ) located under the
cover and simultaneously press the platform lowering button until the safety mechanisms are
deactivated (alarms stop) and therefore normal movements are possible again, or until the
operator can be rescued.
