ABSTRACT:
Powered and steerable telescoping conveyors. The telescoping conveyors have an infeed section and a discharge section. The discharge section can be telescoped beneath the infeed section in a retracted position. In an extended position, containers can be conveyed over first and second conveying structures that are located on the infeed and discharge sections, respectfully. The conveying structures can include wheels, rollers, or belts. A power module can move the discharge section between the extended and retracted positions. The power module can be located at various positions along the conveyor, including at a discharge end of the discharge section. A steering assembly can be provided to orient the discharge section with respect to the infeed section. The steering assembly can include two wheels, each wheel having its own independent wheel-steering axis. A power module can be associated with each of the independent wheels. The conveyor can be provided with guide rails and guide pins to align the discharge and infeed sections. There can be a bumper bar to brake the conveyor if the conveyor contacts an immovable object. The entire conveyor can be portable.
