Abstract: A conveyor structure which comprises a base and a plurality of booms mounted thereon. The booms are interconnected to move in and out together. A belt travels on upper plates of the base and booms. A belt take-up carriage is connected to boom advancing means so that the length of the portion of the belt on the upper plates is increased as the booms are extended and reduced as the booms are retracted.
