Self-transporting multiple conveyor system
First Claim
1. A self-transporting multiple conveyor system comprising a pair of longitudinally extending conveyor frames, a conveyor belt supported on pulleys on each frame, a separate axle and wheel set associated with each of said frames for supporting its respective frame for transport on a highway, each axle extending horizontally and having opposite ends, the wheel set of each axle including a highway transport wheel adjacent each end of the axle, the frames each having an end arranged to be towed by a highway tractor, disengageable coupling members for joining the frames in close side-by-side relation during highway transport, the axle of each conveyor frame including a part with an associated highway transport wheel that extends under the other conveyor frame when the frames are coupled side-by-side so that the associated wheel underlies the other conveyor frame, and a fifth wheel pin at said frame ends arranged to serve both of said conveyor frames for towing said conveyor together with a highway tractor.

Abstract
A self-transporting conveyor system suitable for handling the discharge of a rock or concrete crusher, for example. The system includes a pair of stacking conveyors and a pair of transfer conveyors all of which are assembled together for towing by a single highway tractor. The conveyors can be set up at a desired site using available equipment, such as a loader, so that the cost of a special crane is avoided. Each stacking conveyor includes a self-contained hydraulic power supply that allows it to hydraulically fold up for transport, and unfold for operation, and enables it to hydraulically pivot back and forth during operation to build a kidney-shaped pile.

- 8. A conveyor for stacking crushed material comprising an elongated frame extending between a material receiving end of the conveyor and a discharge end of the conveyor, a conveyor belt for circulating over the frame, a set of highway transport wheels on the frame between the receiving end and the discharge end for transporting the conveyor over a roadway, each of said wheels being selectively pivotal about a substantially vertical axis alternatively between a position for transporting the conveyor over a roadway and a position for supporting the conveyor for radial movement about a pivot center adjacent the receiving end, and a motor associated with one of said highway transport wheels to drive said one wheel in alternative rotary directions when said wheel is in said radial movement position whereby the discharge end of said conveyor can be moved laterally to create a kidney-shaped pile of material.

10. A self-transporting conveyor system comprising a stacking conveyor having an elongated truss-type frame, the frame having a receiving end and a discharge end, a conveyor belt mounted for circulation on the frame, the frame having a folding point between its ends, the folding point being arranged away from the mid-length of the frame as determined when the frame is in a straight line extended position for operation such that the frame includes a primary section and a shorter secondary section, the secondary section being disposed above a portion of the primary section substantially equal in length to the length of the secondary section, and a transfer conveyor separate from and independently operable of the stacking conveyor, the transfer conveyor being carried on the primary section not surmounted by the secondary section in its folded position temporarily during transport of the system from site to site.
