ABSTRACT:
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. A first end of each ramp immediately adjacent to the frame is pivotally connected to the frame to allow the frame to be articulated towards the grate. A second end of each ramp spaced from the frame is supported above but in close proximity to the ground. A support frame is associated with each ramp to provide a barrier along the ground adjacent to and at a level of the second end of each ramp. The barrier supports an earthen ramp which enables the material transport vehicles to drive onto and over the ramp to deposit material over the grate. The support frame maintains the integrity of the earthen ramp when the ramps are articulated towards the grate. The support frame may also provide a support surface adjacent to the ground for supporting the second end of each ramp.
