A folding structure supports a duct in a generally horizontal orientation, and permits sweeping and serpentine movement of the duct. The structure is foldable for storage and transport. The structure comprises an array of panels hinged together, with the structure biased upward from its base to its free end for counteracting the weight of the loaded duct.

Support structure for vacuum duct

A conveyor for transporting grain or the like consists of three or more sections foldable about two axes of rotation displaced from each other. Separate retractors operate to fold the conveyor about the two axes. A link connecting the first and second retractors permits a single actuator to fully fold the conveyor about the two axes. The first and second axes may be rotationally displaced from each other by about 90.degree..
