Abstract: Apparatus for elevating materials that is particularly useful in limited spaces and/or where flexibility in positioning is desirable. Fully self-contained, the apparatus is trailer mounted and provided with a hydraulic system for positioning and powering the individual components as needed to feed material from supply trucks to the apparatus and then to vertically elevate the material for distribution to desired locations as needed for such purposes as, for instance, delivering proppant to site storage for hydraulic fracturing of oil wells. The individual components, including a material-receiving feeder pan, inclined auger, rotatable tower mount, and bucket elevator are preferably trailer-mounted and the bucket elevator is selectively positionable from a first, position for operating and elevating materials to a second position for over-the-road transport.
