The Patriot Lift Company is participating in a Two Phase demonstration project with Meritor WABCO to integrate Patriot's unique, patented, pneumatic lift systems into the Meritor WABCO Trailer ABS system and new truck mounted PLC display.
Phase One will use the ABS speed sensors and a proximity switch to
automatically raise the landing gear, if it is not completely raised at the time
a target speed is reached. If the tractor trailer rig is moving faster than a
user optional speed (user preset @ 5, 10, 15 mph etc) and the proximity
switch indicated the gear is partially lowered, the Meritor WABCO Anti
Lock Braking System will trigger a signal to a solenoid in the Patriot Lift
control box to raise the gear and will alert the driver on the display.
Occasionally drivers may move off with partially extended gear and
increase the potential for damaging the gear. Integration of the Patriot Lift
pneumatic systems and the Meritor WABCO Anti Lock Brak ing System will
eliminate most if not all landing gear damage caused by partially lowered
This Phase has been completed and successful, currently the Meritor
Wabco technology trailer is touring.
Phase Two of this project will show the Landing Gear status in the cab to
the driver and will allow the driver to raise or lower the landing gear with
the Up/Down keys on the display in his / her cab when at zero speed,
completely shielding the driver from any Landing Gear raising and
lowering injuries, keeping him / her out of the weather, and streamlining
the Landing Gear management process."
