A mobile, road-hauled aggregate material processing plant comprising: a wheel mounted chassis extending in a longitudinal direction; a plant support frame mounted on the chassis; a raw material input hopper mounted on the plant support frame; a material processing means mounted on the plant support frame and fed from the input hopper and having an outlet; processed material outfeed delivery means mounted on the plant support frame and fed from the material processing means; at least one lateral delivery conveyor incorporated in the outfeed delivery means, said conveyor comprising: a conveyor frame tail section; a conveyor frame head section; a tail articulation means connecting the tail section to the support frame in such a way that at least part of the tail section is movable relative to the plant support frame from an operative position extending laterally of the chassis with respect to the longitudinal direction for outfeed of processed material, to a transport position extending substantially upright above the chassis and positioned with respect to the input hopper and material processing means so that it does not project laterally beyond the chassis; a head articulation means connecting the head section to the tail section in such a way that the head section is movable from an operative position to a transport position with the head section extending longitudinally above the chassis and positioned with respect to the input hopper and material processing means so that it does not project laterally beyond the chassis; a plurality of rollers mounted on the conveyor frame; and an endless conveyor belt mounted on the rollers to complete the assembly of a lateral delivery conveyor having tail and head sections, said belt defining a conveyor plane. view more

A processing plant as claimed in claim 1, wherein: the tail articulation means comprises a pivot joint connecting at least part of the tail section to the plant support frame, said joint having a pivot axis extending substantially longitudinally and horizontally; and the head articulation means comprises a pivot joint connecting the tail and head conveyor frame sections and having a pivot axis extending substantially perpendicular to the conveyor plane. view more

A processing plant as claimed in claim 2 wherein the pivot joint of the head articulation means comprises a fixed pivot pin mounted on the conveyor frame tail section and a rotatable bushing mounted on the conveyor frame head section.

A processing plant as claimed in claim 1 further comprising a lateral support bracket mounted on the plant support frame for support of the lateral conveyor head section when in the transport position.

A processing plant as claimed in claim 1 wherein: the conveyor rollers are arranged in a trough-like configuration comprising a central lower roller and a pair of side rollers extending laterally and upwardly with respect to the conveyor frame, said configuration providing for self-centring of the conveyor belt in operation; and the conveyor belt has a substantially smaller width than the conveyor frame for accommodation of articulation of the head section. view more

A processing plant as claimed in claim 1, wherein the lateral conveyor tail section comprises: a fixed part mounted on the plant support frame and extending laterally above the chassis and beneath the material processing means outlet; and a pivoting part connected to the fixed part by the tail articulation means, said pivoting part being movable by the tail articulation means. view more

A processing plant as claimed in claim 1 wherein the tail and head articulation means comprise a drive means for causing movement of the lateral conveyor between the operative and transport positions.

A processing plant as claimed in claim 7 wherein said tail articulation means comprises an hydraulic ram drive means mounted between the plant support frame and the tail section and said head articulation means comprises an hydraulic ram drive means mounted between the tail and head sections. view more
