The end upper chassis 19 is offset in the length direction and then engages with the lowered middle upper chassis 2.

The end upper layer underframe 19 is of an arc structure, the middle part is high, and the two sides are low. As can be seen from the above construction, there is thus a large space between the raised floor 20 and the end upper floor frames 19 to accommodate the car, since the car is also raised in the middle and lowered in both sides.

The end-put-on-shelf control device also comprises a transverse stabilizer bar; one end of the transverse stabilizer bar is connected with the upper-layer underframe 19 at the end part, and the other end of the transverse stabilizer bar is connected with the outermost supporting sleeve 25 of the multistage telescopic sleeve 23; the transverse stabilizer bar is used for enclosing a stable triangle with the multistage telescopic sleeve 23 and the end upper layer underframe 19; the transverse stabilizer bar is detachable. The stabilizer bar can improve the lateral stability of the end portion upper chassis 19 and prevent the end portion upper chassis 19 from swinging in the width direction. The transverse stabilizer bar can select a pull rod with adaptive length or an adjustable telescopic threaded rod, and has simple structure and low manufacturing cost. The stabilizer bar is projected on the end upper chassis 19 in the width direction of the end upper chassis 19. The stabilizer bar is detachably connected, and the stabilizer bar is installed after the position of the end upper chassis 19 is determined, and the stabilizer bar is used when the end upper chassis 19 needs to bear.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
