Abstract

A transportable apparatus for unloading material directly from a dump truck onto a conveyor assembly. The transportable apparatus includes an inclined ramp that is adapted to permit a dump truck to back onto the ramp. A hopper assembly is movably mounted to the rear end of the inclined ramp and is positioned to receive material unloaded from the dump truck. The hopper assembly includes a hopper bin mounted to the back end of the inclined ramp by a pair of support arms. The first end of the each support arm is connected to a drive member such that the hopper bin can be raised and lowered relative to the inclined ramp. A wheel assembly is also mounted to the rear end of the inclined ramp. The wheel assembly is mounted between a pair of support arms. The inner end of each support arm is pivotally connected to the inclined ramp, while the outer end of the each support arm for the wheel assembly is connected to a wheel axle. The raising devices are operable to raise the inclined ramp relative to the wheel assembly for transportation and lower the incline ramp relative to the wheel assembly for receiving the dump truck.
