Abstract
A suspension repositioning system for a trailer is provided that includes a trailer frame having spaced apart rails with a plurality of sets of holes in the rails. A suspension unit is movable relative to the frame along the rails. The suspension unit has a set of pins movable between locked and unlocked positions which are engageable with one of the plurality of sets of holes in the locked position to secure the suspension unit to the trailer frame. A speed sensor detects a speed of the suspension unit, and a pin position sensor detects the unlocked position of at least one of the pins. An alarm is connected with the speed sensor and the pin position sensor. The alarm sends an alert signal in response to the speed sensor detecting a predetermined speed and the pin position sensor detecting the at least one of the pins in the unlocked position.
