Load Sensing
Load Sensing Axle System (LSAS)
This LSAS system is designed to automatically drop one or more lift axles on a trailer when a load is sensed. This prevents overloading of the trailer's static (down) axles if the operator neglects to drop the lifted axles. The system monitors the load by sensing the pressure in the air suspension.
