Abstract
A material handling lift gate for allowing ingress and egress from a conveyor system. The material handling lift gate provides a mechanism for clearing packages from the lift gate prior to the opening thereof, as well as preventing packages from entering the lift gate when the lift gate is in an open position. The material handling lift gate includes a plurality of adjustable, telescoping vertical legs and opposing horizontal side rails hingedly mounted to an upper end of a pair of the plurality of adjustable, telescoping vertical legs or proximate thereto. The opposing horizontal side rails are positionable between a first closed position and a second open position. In further embodiments, the material handling lift gate includes a lift gate clear controller for controlling package movement into and out of the material handling lift gate.
