The frame is made with a center beam (1.1), on which drive cylinders (5) are installed in the central vertical longitudinal plane O-O. The body is assembled from two semi-bodies (3.1), the bottoms of which are connected by hinges. Support hinges (2) are made self-aligning due to the possibility of transverse rectilinear movement. The drive mechanism of each side flap (4) is made in the form of a rotary lever, the upper end of which is connected to the rotary rocker. The rotary rocker is planted with its middle part on the central vertically movable intermediate axle. By the second lower arm, the rotary rocker is pivotally connected to the drive rod connected to the corresponding side flap (4).

EFFECT: execution of the body of two semi-bodies (3.1), having a much smaller width of the bottoms, allows the opening of the semi-bodies (3.1) and their side flaps (4) at large angles α and β, which reduces the leverage of the force from the weight of the load located on the bottoms and hinged sides (4), it becomes possible to more completely unload the body.
