MULTIPLE-STAGE EXTENDABLE CONVEYOR

摘要

An extendable conveyor includes a base unit and at least two extendable units selectively nested within each other and the base unit, and a conveying member supported by the base unit and any extended portions of the extendable units. The extendable units may be adjustably positioned incrementally between fully nested positions within the base unit or the next most inward extendable unit and fully extended positions telescoped outwardly from the base unit and from one another. Each of the extendable units is supported by a cantilever support system from the next most inward extendable unit or the base and includes at least one rearward support member on each extendable unit engaging the next most inward extendable unit or the base unit and at least one forward support member on the next most inward extendable unit or the base unit supporting the extendable unit. The rearward support members and/or the forward support members are laterally aligned in a vertical plane adjacent a lateral perimeter of the conveying member in order to allow a reduced range in width of the extendable units to accommodate a wider conveying surface relative to the width of the base unit.
