Abstract: A storage container for bulk materials includes a rectangular bin containing a an open-ended chamber having a horizontal bottom wall, a pair of vertical side walls and a vertical rear wall, and a pair of parallel spaced centrally-arranged horizontal guide rails that extend longitudinally below the bin, which guide rails have forward end portions that extend outwardly beyond the bin front end. A ramp wall is pivotally connected with the forward end of the bin for displacement between a vertical first position closing the forward end of the chamber, and a downwardly inclined ramp position. A piston and cylinder motor arrangement is connected between the guide rail ends and the ramp wall for displacing the ramp wall between its vertical first and downwardly inclined second positions. The chamber side walls are spaced so that a front end loader can travel up the downwardly inclined ramp and into the chamber.

Abstract: A retractable tow hook assembly is connected with a rectangular storage container having a vertical ramp end wall hingedly connected at its bottom edge with the container for displacement about a horizontal pivot axis from an initial vertical closed position downwardly toward an inclined loading position in engagement with the ground. The tow hook assembly includes a support plate that is externally connected with the container adjacent the hinge connection, and a hook member that is displaceable relative to the support plate between an upwardly extending towing position for engagement by the loop of a towing cable when the ramp wall is in the vertical position, and a non-obstructing downwardly-displaced retracted position when the ramp wall is in the downwardly inclined loading position. A stop arrangement prevents displacement of the tow hook member beyond the extended position.
