Test the Platform Overload
System - GS-30m, GS-30,
GS-32m, GS-32, GS-46, GS-55
Genie specifications require that this procedure be
performed annually OR when the machine fails to
lift the maximum rated load.
Testing the platform overload system regularly is
essential to safe machine operation. Continued
use of an improperly operating platform overload
system could result in the system not sensing an
overloaded platform condition. Machine stability
could be compromised resulting in the machine
tipping over.
The platform overload system is designed to
prevent machine operation in the event the
platform is overloaded. Models equipped with the
platform overload option are provided with two
additional machine control components: the
overload pressure transducer and the platform
height sensor.
The overload pressure transducer, located at the
barrel-end of the lift cylinder, is used to determine
the pressure inside the lift cylinder.
The platform height sensor, located at the steer
end of the chassis, is used to determine the height
of the platform.
The overload pressure transducer and the platform
height sensor provide the GCON with necessary
information to determine the load in the platform.
1 pressure transducer
2 platform height sensor
1 Turn the key switch to the ground controls
position and pull out the red Emergency Stop
button to the on position at the platform
