Abstract
A conveyor arrangement is particularly adapted for use in tractor trailers and utilizes a pair of free conveyors extending parallel and generally mounted to the trailer floor adjacent the trailer sidewalls. An elongate powered conveyor extends parallel to the free conveyors and is mounted medially on the tractor floor. The powered conveyor includes an upwardly shiftable platform which rides longitudinally upwardly and downwardly on ramps and is moved thereon by a linear actuator including a leverage arm and linkage. A continuous conveyor chain travels about the upwardly and downwardly shiftable platform and is driven by a motor and sprocket arrangement. The chain drive motor and the linear actuator for causing upward shifting are housed in an enclosure located beneath the tractor trailer floor and which is accessible from beneath the trailer for maintenance.
