O RESCUE OPERATOR FROM 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 ( 229 ) 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 ( 229 ) 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 platform E-stop button ( 46 ) or a safety device does not allow normal movement from
the ground control box, the overriding system is operated as follows :
• Break the seal on "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.

SWITCH MUST BE AN EXCEPTION AND NOT A
NORMAL EMERGENCY OPERATION
.
ONLY in this situation, activate the "overriding system" switch located under the sealed cover
and simultaneously activate boom telescoping switch ( 9 ) to retract boom or switch ( 10 ) to
raise or lower boom or switch ( 12 ) to lift or lower the top arm until the safety mechanisms are
deactivated (alarms stop) permitting normal movements again, or until the operator can be
rescued.
