ABSTRACT:
Highway safety regulations generally limit the length of trailers to 75'. Most large conveyors generally have two top folds, one at each end of the conveyor. This format facilitates a trailer which is balanced on a wheeled support both in an unfolded operative position and a folded towing position. The mono-fold trailer conveyor comprises: a main conveyor section having a feed end portion; one and only one folding discharge conveyor section having one end hingably attached to the main conveyor section and having a length exceeding one half of the length of the main conveyor section; and, a counterweight positioned on the feed end portion of the conveyor, necessitated by the otherwise unbalanced folding discharge conveyor section, and sized to stably maintain the discharge end of the conveyor in an elevated position when the conveyor is in an operative unfolded position. With a counterbalanced mono-fold trailer conveyor there is a substantially greater horizontal run between the wheeled support and the discharge end of the conveyor. This means that a mono-fold conveyor can stockpile a substantially greater volume of material than a bi-fold conveyor of similar length without being moved. The mono-fold trailer conveyor is also easier and less costly to manufacture; stronger; and safer to transport, setup and operate; than large trailer conveyors of conventional design.
