COMPACTLY FOLDABLE RADIAL LUFFING STACKER ABSTRACT OF THE DISCLOSURE An elevating conveyor for use in a portable luffing stacker or the like and adapted to be collapsed and folded from an erected operational position to a compactly folded transport position, comprising a multi- section conveyor frame adapted to support a conveyor means, an elongated conveyor means supported by said conveyor frame, said multi-section frame comprising a plurality of contiguous frame sections pivotally connected to each other, said frame sections being movable to an operational position about their correspond- ing pivotal axes to form an elongated conveyor supporting frame in which the plurality of sections lie on a common longitudinal axis, each pair of contiguous frame sections being pivotally mounted with respect to each other about a corresponding canted pivotal axis to permit compact folding of said frame sections. In a further feature of the construction, a mast structure is provided for supporting the elevating conveyor when in operational position. The mast structure includes a tower mast section which is pivotally foldable relative to a base mast section to a horizontal transport position about a substantially horizontal first pivotal axis. The mast structure also includes a telescopic mast section from which the elevating conveyor is suspended and which is telescopically movable relative to the rest of the mast structure upwardly to an operational position or down- wardly to a retracted transport position. When in retracted position, the telescopic mast section is foldable to transport position about a horizontal second pivotal axis which coincides with the axis about which the tower mast section structure folds to transport position. In a further feature of the construction, means is provided for vertically moving the telescopic mast section and thus for vertically moving the elevating conveyor, including a hydraulic ram assembly which forms part of the telescopic mast section, and in which the hydraulic cylinder element, the piston rod element, and a vertically movable slide member carried by one of said elements are so interrelated with each other and with the stationary tower mast section by interconnecting flexible means such as chains, that operation of the hydraulic ram assembly imparts vertical movement to the telescopic mast section and thus to the elevating conveyor by a "bootstrap" type of operation.
