Description

[Detailed Description of the Invention] The present invention relates to a dump truck that allows a worker to easily climb onto a cargo box from the rear of the cargo box.

Generally, in a dump truck, the upper surface of the cargo box is covered with a canopy to prevent loaded materials such as earth and sand from scattering during driving. Since the work of covering the canopy is performed by climbing onto the cargo box, it is necessary to provide locations at the front and rear of the cargo box where the worker can climb onto the cargo box.

By the way, the step that climbs up onto the cargo box from the rear of the cargo box is conventionally attached to the rear of the floor that makes up the cargo box, so if this step extends downward for a long time,
When dumping a cargo box, it would hit the rear bumper or tail lamp, so we decided to shorten the length of the step to avoid interference between the rear bumper and the stay.

Therefore, the ground clearance of the steps becomes higher,
There is a problem where it is difficult to put your foot on the steps.

The present invention is intended to solve the above-mentioned problem, and an embodiment will be described below with reference to the drawings. 1 is a car body, 2 is a cargo box mounted on the car body 1, and this cargo box 2 has a hinge part 3 at the rear end of the car body 1. It is designed to be able to tilt backwards when centered. Reference numeral 4 designates a tailgate which is pivotally supported 5 at the upper part of the rear end of the cargo box 2 and is swingable to open and close the rear surface of the cargo box 2.

A step member for a worker to climb onto the cargo box 2 is attached to the side of the rear surface of the tailgate 4. This step member is the tailgate 4
A U-shaped first step member 6 whose upper end is fixed and hangs down at the lower part of the rear surface, a second step member 7 installed between the vertical portions of the first step member 6, and a second step member 7.
A third step member 8, a fourth step member 9, and a fifth step member 10 are provided on the rear surface of the tailgate 4 above the step member 7 at equal intervals vertically.

In addition, 11 is a rear bumper attached to the rear end of the vehicle body 1, and 12 is a cargo box 2 located inside the first step member 6.
This is the tail lamp installed in the.

As described above, in the present invention, by attaching a step member that hangs down to an appropriate length from the lower end of the rear surface of the tailgate, when the cargo box tilts backward, the tailgate swings rearward about the pivot support. Therefore, the step member is far from the rear end of the vehicle and does not hit the rear bumper, so the step member can be hung longer than the tailgate to lower the ground clearance of the step member, making it easier to climb onto the cargo box. be able to.
