Abstract
A pick-up and dump machine is mounted on rails for travel along the length of the intermediate space between two parallel row-like mounds of material piled on a storage field. A conveyor belt extending along the length of such intermediate space can feed material to and from the pick-up and dump machine. The machine is provided with supports engaging the conveyor belt to form a conveyor-belt loop having an infeed run terminating in a dump end followed by an intermediate run, followed by an outfeed run. A horizontally swingable dump boom has a dump conveyor whose inward end is located to receive material from the dump end of the conveyor-belt loop irrespective of the side to which the dump boom is swung. A horizontally swingable pick-up boom has a scoop conveyor which engages the side of a mound to be torn down and dumps onto the outfeed run of the conveyor-belt loop. The two booms and their conveyors can operate simultaneously, one receiving material from the conveyor belt while the other discharges material onto the belt, whereby a mound at one side of the machine can be built up while the mound at the other side is being torn down.
