A portable truck dump comprises a conveyor system mounted on an elongate frame to transport material from a first end of the frame to a second, opposite end of the frame. A grate is positioned over the conveyor system and is supported by first and second sides of the frame. A ramp extends generally perpendicular to the frame on each side of the frame next to the grate to provide a drive-over access for a material transport vehicle to deposit its load over the grate and onto the conveyor system and a portion of each ramp. A first end of each ramp immediately adjacent to the frame is pivotally connected to the frame to allow the ramp to be articulated towards the grate to move excess material off of the ramp and into the grate.
