Special Projects: Geax XD9
One of our projects was based around the Geax XD9. Below is an in-depth description of the work done by our Plant Manager, Dave Webb.
Following the purchase of the XD9, the customer requested us to modify it, to limit the operating height.
The reason for the request was so whilst working in restricted headroom, when pulling back on the joystick to raise the mast it would only raise to a pre-defined height and not collide with the roof of the building.
The solution was to fit a blocking solenoid valve into the joystick up pilot line, this was activated by an electrical switch mounted to the mast post, the switch could be varied in height from 2 metres to 3 metres in 100 mm increments.
When lifting the mast, it would raise to the point of tripping the switch, this in turn powered the solenoid valve, which cut the flow/ pressure to the up pilot line.
The switch could be overridden in the cab by another switch if required.
