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 for supporting the second end of each ramp. A drive-on ramp contacts an end portion of the support frame.

Dependent claims

A portable conveyor system for unloading material transport vehicles comprising:

a frame having a first end, a second end, a first side and a second side, the frame configured for connection to a towing vehicle, the frame carrying a belt conveyor system generally from the first end to the second end, a portion of the frame adjacent to the first end configured to rest on a ground surface;
a grate supported by the frame near the first end of the frame, the grate being positioned over a portion of the belt conveyor system;
a first drive-over ramp pivotally connected to the first side of the frame adjacent to the grate;
a second drive-over ramp pivotally connected to the second side of the frame adjacent to the grate;
the first drive-over ramp, second drive-over ramp and grate capable of supporting a material transport vehicle for depositing material through the grate when the first and second drive-over ramps are in a first position, the first and second drive-over ramps capable of catching excess material deposited by the material transport vehicle, the first and second drive-over ramps pivotable to a second position to clear the excess material off of the ramps directly into the grate.
