Proposed is a wheeled drop-floor trailer that has a U-shaped frame with two articulated linkages pivotally installed on the sides of the U-shaped frame and suspension rods that pivotally support the drop floor in a freely hanging condition. On the side of the trailer opposite the loading side the articulated linkages are interconnected by a cross bar, which is connected to a drive mechanism, e.g., to a winch, via a cable. When the articulated linkages are inclined toward the loading side, the drop floor descends to the ground under its own weight and, after the cargo is loaded onto the drop floor, the latter is raised by pulling the linkages with the use of the winch via the cable and the cross bar in the direction opposite the loading side. |
