The rails 31, the runners 32 and the braces 33 form a walking support device 30, one end of which is hinged to the bottom end of the cargo box 10 and the other end of which is connected to the subframe 20. When the jacking mechanism 40 works to drive the container 10 to rotate, the walking support device 30 is driven by the support rods 33 to walk along the track 31; when the jacking mechanism 40 stops, the brace 33 is supported between the cargo box 10 and the subframe 20, which can be used for auxiliary support; if the jacking mechanism 40 breaks down suddenly, under the gravity of the container 10, the support rods 33 push the walking part 32, so that the walking part 32 walks along the front of the track 31; since the first tooth portion 313 and the second tooth portion 3221 are engaged with each other between the running member 32 and the rail 31, the running member 32 does not instantaneously run to the foremost end, so that a certain degree of buffering effect can be exerted on the falling of the cargo box 10, and the cargo box 10 is prevented from being instantaneously dropped to generate a large impact. Therefore, the traveling support device 30 provided between the cargo box 10 and the subframe 20 can ensure smooth landing of the cargo box 10 and improve the safety of the dump truck.

While the invention has been described with reference to the above embodiments, the scope of the invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the invention.
