Further, according to the present invention, there is a configuration in which an earth auger is detachably attached to the tip of the arm, and other configurations are similar to those of the above-described earth auger device.

[0007]

The earth auger device configured as described above is driven by a driver when the driver enters the cab and operates the operating device, and is self-propelled by a tire from a predetermined parking place to a construction site. Next, at the construction site, the operator rides on the cab to operate various control devices, appropriately controls the operation of the earth auger, the bending and stretching of the arm, and the turning of the main body with respect to the chassis, and the excavation point by a small movement. Position the bottom edge of the earth auger with respect to. As described above, the earth auger can be moved by itself on an ordinary road, and does not require a separate transportation means such as a trailer as in the conventional case.

Further, in the structure in which the earth auger is detachably attached to the arm tip, the earth auger can be replaced with a high frequency pile punching machine or the like to perform other work, so that the range of work contents can be widened. Is possible.
