Abstract
An extendable conveyor has an extendable conveyor section supported in a cantilevered manner including at least one extendable conveyor unit that is extendable between an extended position and a retracted position nested within the extendable conveyor section. The conveyor further includes a user interface section supported in a cantilevered manner from the extendable conveyor unit. The user interface section is vertically adjustable about a horizontal axis and horizontally adjustable about a vertical axis. The extendable conveyor includes a conveying surface defined on the extendable conveyor section and the user interface section. The user interface section is vertically adjustable by an actuator that is preferably an electric motor type linear actuator that is horizontally oriented. This allows the actuator to fit within the side profile of the interface of the user interface section with the extendable conveyor unit.
