ABSTRACT:
A vehicle for supporting cargo in two tiers includes a lower frame for supporting cargo at a lower level and an upper frame for supporting cargo in an elevated position above the lower frame. The vehicle includes a forward support tower and a rear support tower. The forward support tower is pivotally connected to and supports the forward portion of the upper frame. The rear support tower is pivotally connected to and supports the rear portion of the upper frame. The support provided to the rear portion of the upper frame by the rear support tower is longitudinally displaceable, relative to the rear support tower. The lower portion of the rear support tower is pivotally connected to and supported by the rear portion of the lower frame. The rear portion of the upper frame supported by the rear support tower can be longitudinally displaced relative to the rear support tower, and the upper frame can be pivoted, at the forward portion thereof, about the pivotal support on the forward support tower, to move the upper frame between an upright position and a loading position. In the upright position, the upper frame is supported in an elevated substantially horizontal alignment by the forward support tower and the rearward support tower at a clearance height sufficiently above the lower frame to facilitate loading of the lower frame. In the loading position, the upper frame is inclined with the rearward portion thereof extending downwardly to facilitate loading and unloading of the upper frame while the forward portion thereof remains at substantially the clearance height.
