20110079488 | Portable low profile drive-over truck dump conveyor system - 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 for supporting the second end of each ramp. A drive-on ramp contacts an end portion of the support frame. | 2011-04-07 |
