ABSTRACT

A system and method are provided for automated engaging of a truck trailer at
a loading dock. Sensors measure a distance and an angle of alignment between
the incoming trailer and a wall of the loading dock. An outside lighting
system guides a truck driver backing the trailer toward the dock door. A
vehicle restraint system fixates the trailer within the loading dock in
response to signals from the sensors. An overhead dock door opens once the
trailer is successfully fixated by the vehicle restraint system. A dock
leveler deploys after the overhead dock door opens. An inside dock light
indicates to dock personnel that the trailer is ready to be serviced. Once
servicing of the trailer is finished, an automated release of the trailer from
the loading dock may be initiated by PLC communication.
