CONVEYOR STRUCTURE

摘要

A conveyor structure is disclosed having a set of Hframes each comprising two substantially parallel rigid supports of equal length and a cross-member arranged to support a conveyor belt. The H-frames are pivotally joined together in zig-zag configuration with corresponding ends of each of the rigid supports being pivotally connected whereby the set of frames is able to extend and retract in concertina fashion between a compact transport configuration in which the rigid supports of adjacent frames are substantially parallel and an extended zig-zag support configuration. The angular separation between adjacent frames is limited by a plurality of links extending between the frames.
