Abstract
A trailer unloading system anchors one or more trailers to a deck, with, or without tractor attached. The sides of the trailers are free to pivot from a top, longitudinal, pivot axis once unlatched from the edge of the trailer floor. The deck tilts the trailers sideways, the doors swing free, and the load discharges. The deck returns to level, the sides latch to support the floor and the trailers are ready to be reloaded.
