From both sides, the crane device 30, the earth auger device 40, and the bucket excavator 60 are rotated to an angle of 90 degrees sandwiching the working area and extended. In addition, the rear outrigger device 52
The pair of rear arms 55, 55 are extended in the width direction of the base 31.

Thus, the front outrigger device 5
Since 1 can sandwich the work area of the crane device 30, the earth auger device 40, and the bucket excavator 60, the base 31 can be reliably supported even when the center of gravity moves in the work area direction during work. can do.

When the arms 53a and 53b are rotated to a predetermined angle and the rear arms 55 and 55 are extended, the engaging member 36 between the base 31 of the crane device 30 and the carriage 20 is released, and the front outrigger device 51 is released. And the rear outrigger device 52 is driven. As a result, each arm 5
Legs 54, 5 provided on 3a, 53b, 55, 55
4, 56, 56 are extended in the installation surface direction.

Thus, the base 31 is supported by the outrigger devices 51 and 52 on the installation surface of the work place. If the base 31 is firmly supported, then the base 31
Is lifted from the trolley 20.

Next, the trolley 20 is operated remotely, and the base 31
The dolly 20 is moved from the lower side to the outer side. The carriage 20 and the crane device 30 can be operated separately. The trolley | bogie 20 can carry between the truck which loaded the electric pole, and the crane apparatus 30 by mounting an electric pole with the winch on the upper stand 20a. The dolly 20 may be used to carry materials other than electric poles.

When working with the crane device 30, with the bucket excavator 60 removed from the tip of the third boom 34b of the crane device 30, the crane device 30 is driven by a hydraulic device and grounded at the position where the pillar is to be built. The auger device 40 is arranged. As shown in FIG. 6, the earth auger device 40 in the working position has a rotating shaft 41 oriented in the vertical direction. After the arrangement is completed, the earth auger device 40 is hydraulically operated.
It is possible to rotatably drive the rotary shaft 41 of and to make a hole in the ground by the rotary blade 42.

When the formation changes to a formation such as bedrock, soft rock, or gravel layer that cannot be excavated by the earth auger device 40, the earth auger device 40 is rotated from the working position to the storage position, and as shown in FIG. The bucket excavator 60 is attached to the tip of the third boom 34b of the crane device 30. The ground auger device 40 in the retracted position has the rotating shaft 41 stacked along the second boom 34a.

The bucket excavator 60 includes the third boom 34b.
It can be installed with one touch. After mounting the bucket excavator 60, the bucket excavator 60 is driven by a hydraulic device to excavate with the bucket 62,
dig a hole.

As described above, since the bucket excavator 60 can be used in addition to the earth auger device 40, the earth auger device 40 can be used even when the geology for digging a hole includes rocks, soft rocks, and rock formations. By selectively using the bucket excavator 60 to dig a hole, the labor and cost of separately arranging or transporting the excavating machine can be eliminated, and the work efficiency can be improved.

Once the holes have been dug to a depth sufficient to build the pillars, the pillars are roped to the pillar suspensions 35 of the crane device 30.
, The crane device 30 is driven to lift the pillar, and the pillar is erected in the hole. When operating the crane device 30, FIG.
By rotating the operation panel 80 so as to project from the side portion of the base 31, as shown in FIG. 3, the operator can operate while looking at the work state in the front, which is easy to operate.

Excess soil after digging can be leveled by driving the truck 20 and smoothing it by the soil discharging plate 22.

After the work is completed, when the dolly 20 is attached to the base 31, the dolly 20 is remotely operated and placed below the base 31 (see FIG. 8). At this time, the installation locations of the carriage 20 and the base 31 need to be as horizontal as possible. Next, a pair of front and rear connecting member coupling portions 31b on both sides of the base 31 and the corresponding hooks 2 for suspending the carriage 20.
0b is hooked and connected by a connecting member 11 made of a chain (see FIG. 9). The position of the connecting member 11 to be hooked is the same at all four positions.

Once connected, the front outrigger device 51 and the rear outrigger device 52 are driven as described above to move the legs 5 of the arms 53, 53, 55, 55.
Extend 4,54,56,56. As a result, the base 31
Raise. As the base 31 rises, the carriage 20 is hung horizontally by the connecting member 11, and the carriage 20 is vertically suspended by its own weight.
It moves to a central position aligned with the base 31 (see FIG. 10).

Since the carriage 20 is hung at a total of four places, one pair each at the front and rear, it is hung in a well-balanced manner, and the connecting members 11 at the four locations cancel out the shaking of the dolly 20 respectively. The base 31 can be immediately aligned.

With the carriage 20 and the base 31 aligned,
The front outrigger device 51 and the rear outrigger device 52 are driven in the opposite direction to the above to contract the outrigger cylinder, and the respective arms 53a, 53b, 55, 55.
The legs 54, 54, 56, 56 of the are contracted.

In this way, the base 31 is lowered and the carriage 20
Down onto a level installation surface. Since the trolley 20 is suspended so that the ground contact surface of the rubber crawler 21 is horizontal, it is positioned at the installation location in the same posture as the suspended state. Further, the base 31 is lowered to move the base 31
Is placed on the base 20a of the carriage 20 (see FIG. 11).

At this time, the alignment ring 23 of the trolley 20 and the alignment protrusion 31b of the base 31 are fitted to each other, and the trolley 20
And the base 31 for matching. Since the alignment protrusions 31b are tapered, the alignment ring 23 extends along the taper.
Even if the trolley 20 and the base 31 are slightly deviated from each other, they are aligned at accurate positions.

As described above, even when the carriage 20 is arranged below the base 31 at a position different from the mounting position, once the carriage 2
By suspending 0, the base 31 and the carriage 20 can be aligned at the mounting position. Therefore, even without a high level of control technology, it is possible to easily perform the work of returning the dolly 20 after the work to the base 31 and attaching the dolly 20 without any trouble.

If the base 31 is placed on the base 20a, 4
The base 31 and the carriage 20 are attached by the ratchet type engaging members 36 at some places. First, the lever 36b is rotated downward to remove the engagement block 36d of the shaft 36c and the engagement bracket 36a. For attachment, the engagement block 36d is hooked on the engagement bracket 36a, and the lever 36b is rotated upward.

In this way, the base 31 and the carriage 20 can be easily attached with one touch. Further, by rotating the cap nut 36e to adjust the position of the engagement block 36d, the engagement block 36d and the engagement bracket 3
The degree of engagement with 6a can be adjusted.

Further, when the engagement block 36d is engaged with the engagement bracket 36a, the hole 36f of the lever 36b is formed.
By inserting a movable bar 36g into the
It is possible to fix b and prevent the engaging member 36 from being accidentally disengaged.

Next, another embodiment of the present invention will be described. FIG. 12 shows another embodiment of the present invention. It should be noted that the same types of parts as those in the above-described embodiment are denoted by the same types of reference numerals, and redundant description will be omitted.

As shown in FIG. 12, the front outrigger devices 51a are provided on both sides of the base 31. The front outrigger device 51a includes a pair of arms 53,
53 and legs 54a, 54a attached to the free ends of the arms 53, 53. A pair of arms 53,
53 are rotatably attached to both sides of the base 31.

Thus, the front outrigger device 5
The 1a may be arranged on both sides of the base 31 instead of being arranged on the front side thereof.
