Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventional boom-mounted column driving vehicles are dedicated vehicles for excavating holes with a suspended excavation device or installing columnar members by suspending columnar members, and their loading is also limited. Therefore, it is necessary to transport columnar members, construction equipment for column driving work, or excavated soil by separate vehicles. For this reason, it is necessary to arrange a plurality of vehicles during construction, and further vehicle replacement work is required. In addition, a crane operator and an assistant worker are required. As a result, construction work such as transporting construction equipment for column driving work and installing columnar members has become complicated.

[0005] The present invention has been made in view of the above problems, and an object thereof is to reduce the number of vehicles and workers required for column driving work and facilitate column driving work.

[0010] [First Embodiment] An example of a multi-functional integrated vehicle according to the first embodiment will be described with reference to the drawings. FIG. 1 shows a multi-functional integrated vehicle 1 as an example of a multi-functional integrated vehicle. The multi-functional integrated vehicle 1 has a driver's seat section 2, a loading platform section 3 behind the driver's seat section 2, and a boom 5 provided on a base 4 fixed to the rear end of the loading platform section 3. In the following description, the X-axis direction is a horizontal direction in which the forward direction of the multi-functional integrated vehicle 1 is defined as positive, the positive X-axis direction is the front, and the negative X-axis direction is the rear. The Z-axis direction is a vertical direction in which the upward direction is defined as positive, and the Y-axis direction is a direction perpendicular to the X-axis and the Z-axis.

[0011] The operation of the boom 5 is performed by driving the cylinder and motor of the boom 5 by a remote control operation box (not shown) via the control panel 7(1) or 7(2). The cylinder is, for example, a hydraulic cylinder, and the control panel 7(1) or 7(2) controls it via a hydraulic pipe, an electromagnetic valve, etc. The motor is, for example, a hydraulic motor, and the control panel 7(1) or 7(2) controls it via a hydraulic pipe and a speed reducer, etc. Note that the motor may be an electric motor.

[0012] A floor plate 8 is provided on the loading platform section 3. A support portion 9 is erected from the front end of the floor plate 8, and a rear wall 10 is erected from the rear end of the floor plate 8. A space 11 with a predetermined height where the boom 5 does not interfere is formed above the floor plate 8 between the support portion 9 and the rear wall 10. The positional relationship between the boom 5 and the space 11 will be described in detail in the description of the boom 5. The space 11 is a substantially rectangular parallelepiped having an X-axis direction length L1 and a Z-axis direction length (height) H1, with the base 4 located behind the space 11. The space 11 is formed above the floor plate 8 by utilizing the space between the driver's seat section 2 and the base 4. Also, the control panels 7(1) and 7(2) necessary for the operation of the boom 5 are arranged at positions where they do not interfere with the space 11.

[0013] The boom 5 includes a first link 12(1) erected on the base 4 and a rotating link portion 13 connected to the first link 12(1). The rotating link portion 13 includes a second link 12(2) connected to the first link 12(1) at a first rotation center C1 and a third link 12(3) connected to the second link 12(2) at a second rotation center C2. Further, the boom 5 includes a tool attachment portion 14 engaged with the third link 12(3), and a grapple (holding device) 15 can be connected to the tool attachment portion 14. The tool attachment portion 14 includes a fourth link 12(4) slidably connected within the third link 12(3) and a fifth link 12(5) connected to the fourth link 12(4) at a third rotation center C3 and to which the grapple 15 is connected.

[0014] The first link 12(1) is rotatable horizontally about a turning center T1 with respect to the base 4. The second link 12(2) is rotatable vertically with respect to the first link 12(1) by the driving force of a first cylinder CL1. The third link 12(3) is rotatable vertically with respect to the second link 12(2) by the driving force of a second cylinder CL2. The fourth link 12(4) is slidable in the longitudinal direction of the third link 12(3) by the driving force of a cylinder (not shown). The fifth link 12(5) is rotatable about a third rotation center C3 by the driving force of a cylinder or a motor (not shown). The grapple 15 is rotatable about a fourth rotation center C4 by the driving force of a cylinder or a motor (not shown).

[0015] The boom 5 restricts the downward rotation of the rotating link section 13 by pushing up the second link 12(2) with the pressing force P1 of the first cylinder CL1 and pushing up the third link 12(3) with the pressing force P2 of the second cylinder CL2, thereby avoiding interference between the boom 5 and the space 11 and forming the space 11. For example, by controlling the drive of the first cylinder CL1 and the second cylinder CL2 to maintain the angle θ1 of the coupling line BL1 connecting the first rotation center C1 and the second rotation center C2 with respect to the Z-axis direction at 90° or more, and by maintaining the third link 12(3) in a substantially horizontal position, the space 11 is formed. The restriction on the downward rotation of the rotating link section 13 can be released, for example, by controlling the hydraulic pressure of the first cylinder CL1 and the second cylinder CL2. By releasing the restriction on rotation, it is possible to operate the boom 5 of the articulated mechanism and insert the tip of the boom 5 into the space 11. The space 11 may also be formed by providing a mechanical stopper (not shown) that restricts the downward rotation of the rotating link section 13. When the rotating link section 13 is positioned above the cargo bed section 3, the space 11 is formed, and when the rotating link section 13 is not positioned above the cargo bed section 3, the space 11 is naturally formed.

[0016] To ensure sufficient height H1 of space 11, when the rotating link section 13 is positioned above the loading platform 3, it is preferable that the rotating link section 13 is higher than the upper surface of the driver's cab 2, and that the upper surface of space 11 is higher than the upper surface of the driver's cab 2. Also, when the rotating link section 13 is positioned above the loading platform 3, it is preferable that the tool mounting section 14 is above the driver's cab 2 so that it does not interfere with space 11. For the tool mounting section 14 to be above the driver's cab 2, it is preferable that the pressing force P2 of the second cylinder CL2 straightens the rotating link section 13 so that the front end of the rotating link section 13 is positioned in front of the support section 9. In this example, it is possible to place the tool mounting section 14 on the upper surface of the driver's cab 2, and in that state, the boom 5 (first link 12(1) to fifth link 12(5)) does not interfere with space 11, and space 11 is formed. Furthermore, in order to ensure sufficient height H1 of space 11, it is preferable that the first rotation center C1 is located higher than the upper surface of the driver's seat 2.

[0017] Next, the case in which the support portion 9 supports a utility pole (an example of a columnar body) 18 will be explained based on Figure 2. Near the upper end of the support portion 9, the first recess 17(1), the second recess 17(2), and the third recess 17(3) are provided in order from the left side (positive Y-axis direction side).

[0018] The first recess 17(1) can be engaged by placing the front of the utility pole 18 on it. The rear of the utility pole 18 is supported by an engagement jig 19 placed on an item (not shown) stored in the space 11. At this time, the utility pole 18 is positioned above the top surface of the space 11, and the height H1 of the space 11 is secured. The width W1 of the space 11 is secured by the right side wall 16R and the left side wall 16L which are continuous with the floor plate 8, and the length L1 of the space 11 is secured by the support part 9 and the rear wall 10 which are continuous with the floor plate 8.

[0019] The second recess 17(2) can accommodate the third link 12(3) of the rotating link section 13. The front end of the utility pole 18 may be placed on and engaged with the third recess 17(3). Alternatively, two utility poles 18 may be supported by placing the front end of the utility pole 18 on and engaging with each of the first recess 17(1) and the third recess 17(3). The first recess 17(1) may be provided with a receiving member 20 on which the utility pole 18 is placed. The receiving member 20 is preferably made of cushioning material.

[0020] Here, the boom 5 is structured to be able to grip the utility pole 18, which is placed on the support section 9, with a grapple 15 connected to the tool attachment section 14. For example, by controlling the first cylinder CL1 to lift the rotating link section 13 and bending it at the second rotation center C2, it is possible to grip the utility pole 18 engaged with the first recess 17(1) with the grapple 15. At this time, the boom 5 does not interfere with the space 11. Also, when the rotating link section 13 is above the loading platform 3 and the utility pole 18 is placed on the support section 9, the boom 5 controls the drive of the first cylinder CL1, etc., to restrict the downward rotation of the rotating link section 13, thereby creating a space 11 below the rotating link section 13 and below the utility pole 18. Furthermore, when the utility pole 18 is placed on the support section 9, it is preferable to restrict the rotation of the boom 5 around the pivot center T1 so that the boom 5 does not interfere with the utility pole 18. The rotation can be restricted by controlling the motor for rotation or by a mechanical stopper, etc. Furthermore, if a sensor (not shown) installed on the support part 9 can detect that the utility pole 18 is placed on the support part 9, then when the sensor detects that the utility pole 18 is placed on the support part 9, the downward rotation of the rotating link part 13 or the rotation around the pivot center T1 may be restricted.

[0021] <Effects of multi-functional integrated vehicles> The multi-functional integrated vehicle 1 has a space 11 that does not interfere with the boom 5, so that equipment and materials for pole erection work, such as drilling holes and installing utility poles 18, can be stored in the space 11. For example, as shown in Figure 3(a), a drilling device unit 21 including a drilling device 30 can be stored in the space 11, and as shown in Figure 3(b), a system unit 22, tanks 23 and pumps 24 can be stored in the space 11. In addition, a tool storage box (not shown) and pneumatic parts (not shown) can be stored in the space 11. Therefore, the multi-functional integrated vehicle 1 can be driven to transport equipment and materials for pole erection work, such as drilling holes and installing utility poles 18.

[0022] Furthermore, because the boom 5 has a multi-joint mechanism, it is possible to insert the tip of the boom 5 into the space 11 to connect and hold the drilling device 30 inside the space 11, and to drill a hole while holding the drilling device 30. Therefore, the entire process from holding the drilling device 30 to drilling a hole can be performed by the multi-functional integrated vehicle 1.

[0023] Furthermore, because it is equipped with a support section 9 and the boom 5 has a multi-joint mechanism, the utility pole 18 placed on the support section 9 can be gripped by the grapple 15 connected to the tool attachment section 14 and installed in the hole 26. Moreover, the multi-joint boom 5 can be operated solely by the remote control box to install the utility pole 18 placed on the support section 9 into the hole 26. As a result, the work efficiency of the utility pole 18 installation work is improved, and the need for an assistant during pole erection work is eliminated, thereby improving the safety of the construction.

[0024] As described above, the multi-functional integrated vehicle 1 has the function of transporting equipment and materials for pole erection work, the function of excavating a hole 26 in the ground GL, and the function of installing a utility pole 18 in the hole 26. Therefore, a single multi-functional integrated vehicle 1 can perform a series of pole erection operations, from transporting equipment and materials for pole erection work to excavating the hole 26 and installing the utility pole 18, thereby reducing the number of vehicles and personnel required for pole erection work and making pole erection work easier.

[0025] Furthermore, the multi-functional integrated vehicle 1 can also operate the boom 5 of its articulated mechanism to load heavy pole-erecting equipment and materials from a warehouse or factory into space 11 before moving the multi-functional integrated vehicle 1 to the pole-erecting site. After excavating the hole 26, it is also possible to load the excavated soil into space 11 and transport it to the soil storage area. In addition, after completing the pole-erecting work up to the installation of the utility pole 18, it is also possible to load, transport, and unload heavy pole-erecting equipment and materials. Loading and unloading of pole-erecting equipment and materials can be done, for example, by gripping the equipment and materials with the grapple 15, or by using the hook portion formed on the grapple 15 to suspend the equipment and materials.

[0026] Furthermore, even if there are obstacles such as overhead wires during pole erection work, the boom 5 with its multi-joint mechanism can be operated to avoid or remove the obstacles. As a result, the entire series of pole erection operations, from loading equipment and materials from a warehouse to unloading them, can be easily and safely performed with a single multi-functional integrated vehicle 1. In this case, the number of vehicles and workers used for the entire series of pole erection operations can be reduced, making the pole erection work easier and improving safety.

[0027] In the case of conventional pole-erecting vehicles with linearly telescopic booms, it is necessary to temporarily place pole-erecting equipment using a winch or the like in order to grip it. In contrast, the multi-functional integrated vehicle 1 has a boom 5 with a highly flexible multi-joint mechanism, making it easy to directly grip pole-erecting equipment within space 11 or near the vehicle.

[0028] Furthermore, with the rotating link section 13 on the loading platform 3, a space 11 can be formed below the rotating link section 13 and below the supported utility pole 18. Therefore, while supporting the utility pole 18, equipment for pole erection work can be stored in the space 11, allowing the transport of the utility pole 18 and equipment for pole erection work to be performed by a single multi-functional integrated vehicle 1.

[0029] Furthermore, since the first cylinder CL1 or a mechanical stopper is provided as a restricting device to prevent the rotation of the rotating link section 13 downward when the rotating link section 13 is positioned above the loading platform 3, the rotating link section 13 does not interfere with the space 11. As a result, the space 11 can always be maintained, and equipment for pole erection work can be stored there.

[0030] Furthermore, when the rotating link section 13 is positioned above the cargo bed section 3, and the rotating link section 13 is higher than the upper surface of the driver's cab section 2, and the upper surface of the space 11 is higher than the upper surface of the driver's cab section 2, sufficient height can be secured for the space 11 to store equipment for pole erection work. In addition, multiple pieces of equipment for pole erection work can be stacked vertically for storage.

[0031] Furthermore, when the rotating link section 13 is located above the cargo bed section 3 and the tool mounting section 14 is located above the driver's seat section 2, the tool mounting section 14 does not interfere with the space 11. Therefore, by restricting not only the rotating link section 13 but also the tool mounting section 14 from interfering with the space 11, a space 11 of sufficient width can be formed.

[0032] Furthermore, if the first rotation center C1 is located higher than the upper surface of the driver's seat section 2, the position of the first rotation center C1, which is the base of the rotating link section 13, can be raised to reliably prevent the rotating link section 13 from interfering with the space 11. Moreover, since the first rotation center C1 does not move, a sufficiently large space 11 can be reliably formed.

[0033] Furthermore, if space 11 is roughly rectangular, it is easy to store multiple pole-erecting equipment and materials in space 11. For example, boxes containing pole-erecting equipment and materials units can be easily lined up and stacked within space 11.

[0034] Furthermore, since the support section 9 is erected in front of the space, the support section 9 does not interfere with the space 11. Therefore, it is possible to transport the utility pole 18 while still creating a space 11 that is large enough to store equipment and materials for pole erection work.

[0035] Furthermore, since the boom 5 is structured to grip the utility pole 18 placed on the support section 9 with the grapple 15 connected to the tool attachment section 14, there is no need to lower the utility pole 18 from the support section 9 to the ground and then grip it with the grapple 15. This eliminates the step of lowering the utility pole 18 to the ground, allowing for more efficient installation of the utility pole 18. It also reduces the working area required to install the utility pole 18.

[0036] <Column installation method> The following describes a method for installing columnar structures using the multi-functional integrated vehicle 1. The steps of the columnar structure installation method are an example, and the order is not limited; other steps may be included between each step.

[0037] First, as a preparation step, the equipment and materials for pole erection work, such as the excavation device unit 21, are stored in the space 11 of the multi-functional integrated vehicle 1 in a warehouse or factory, and the utility pole 18 is placed on the support section 9. The equipment and materials for pole erection work may be stored in the space 11 before the utility pole 18 is placed on the support section 9, or the equipment and materials for pole erection work may be placed on the support section 9 before the equipment and materials for pole erection work are stored in the space 11. Next, as a transportation step, the multi-functional integrated vehicle 1 is moved to the pole erection site with the equipment and materials for pole erection work and the utility pole 18 placed on it.

[0038] At the pole erection site, the grapple 15 is removed from the tip of the fifth link 12(5), and the drilling device 30 stored in space 11 is connected. The type of drilling device 30 to be connected is not particularly limited, and may include, for example, a hammer type, a clamshell type, or the drilling device disclosed in Japanese Patent Publication No. 7-62428. The multi-functional integrated vehicle 1 may be moved to the pole erection site with the grapple 15 removed and stored in space 11. An example of the method for removing the grapple 15 and connecting the drilling device 30 will be described below with reference to Figures 4 and 5.

[0039] For example, when moving to a pole erection site, as shown in Figure 4(a), the boom-side attachment 40 fixed to the tip of the fifth link 12(5) and the grapple-side attachment 41 fixed to the grapple 15 are connected by a screw 42. At the pole erection site, with the screw 42 removed, the boom 5 is operated to detach the boom-side attachment 40 from the grapple-side attachment 41 as shown in Figure 4(b), and the tip of the fifth link 12(5) is separated from the grapple 15 to remove the grapple 15. The removal of the grapple 15 can be done in an open space within the space 11 or on the ground level outside the space 11.

[0040] Next, as shown by the dashed line in Figure 5, the boom 5 is operated to move the tip of the fifth link 12(5) toward the drilling device 30 housed in space 11, and as shown by the solid line in Figure 5, the boom-side attachment 40 is engaged with the drilling machine-side attachment 44 fixed to the drilling device 30.

[0041] Subsequently, by fixing the boom-side attachment 40 to the excavator-side attachment 44 with screws 42, the excavator 30 is connected to the tip of the fifth link 12(5) while housed in space 11, as shown by the dashed line in Figure 6. Next, the connected excavator 30 is lifted upward, the boom 5 rotates approximately 180° around the pivot center T1, and the excavator 30 is held vertically above the ground level GL, as shown by the solid line in Figure 6.

[0042] Next, as shown by the solid line in Figure 7, the drilling device 30 is positioned above the hole drilling location at ground level (GL), and then, as shown by the dashed line in Figure 7, the drilling device 30 descends and drills the hole 26. After the hole 26 is formed, the drilling device 30 is returned to the space 11 while still connected to the tip of the fifth link 12(5) by the operation of the boom 5.

[0043] Within space 11, the screws 42 are removed from the boom-side attachment 40 and the excavator-side attachment 44, and as shown in Figure 8(a), the boom-side attachment 40 is detached from the excavator-side attachment 44, and the excavator 30 is removed from the tip of the fifth link 12(5). Next, the tip of the fifth link 12(5) is moved above the grapple 15 within space 11 or on the ground level (GL), and as shown in Figure 8(b), the boom-side attachment 40 engages with the grapple-side attachment 41, and the grapple 15 is connected to the tip of the fifth link 12(5) by the screws 42.

[0044] Next, as shown in Figure 9(a), the second link 12(2) and the third link 12(3) rotate upward around the first rotation center C1, and the grapple 15 moves onto the utility pole 18. Then, as shown in Figure 9(b), the third link 12(3) rotates downward around the second rotation center C2, and with the grapple 15 rotated downward around the third rotation center C3, the grapple 15 grips the utility pole 18 near its center of gravity.

[0045] When the grapple 15 grips the utility pole 18, the second link 12(2) and the third link 12(3) rotate upward around the first rotation center C1, as shown by the dashed lines in Figure 10, causing the grapple 15 to lift the utility pole 18 and separate it from the support part 9. When the utility pole 18 is lifted vertically upward, it separates from the first recess 17(1).

[0046] Next, the boom 5 rotates approximately 180° around the pivot center T1, the second link 12(2) and the third link 12(3) rotate slightly downward, and the grapple 15 rotates upward around the third pivot center C3, so that the utility pole 18 is held vertically above the existing hole 26, as shown by the solid line in Figure 10.

[0047] Next, the utility pole 18 is lowered and inserted into the hole 26, after which the hole 26 is backfilled, the grapple 15 is separated from the utility pole 18, and the utility pole 18 is installed. Once the utility pole 18 is installed, the second link 12(2) and the third link 12(3), etc., are returned to the upper part of the space 11.

[0048] <Effects of the columnar structure installation method> The method for installing a columnar structure includes the steps of connecting an excavation device 30 to a tool attachment part 14 of a boom 5 having a rotating link part 13, excavating a hole 26 in the ground GL, removing the excavation device 30 from the tool attachment part 14 and connecting a grapple 15, gripping the utility pole 18 supported by the support part 9, and installing the utility pole 18 in the hole 26. Therefore, the entire pole erection operation, from connecting the excavation device 30 and excavating the hole 26 to installing the utility pole 18, can be performed by the multi-functional integrated vehicle 1. For this reason, the entire pole erection operation can be performed by preparing only one multi-functional integrated vehicle 1 as the vehicle to be used.

[0049] Furthermore, the pole-shaped installation method restricts the rotation of the second link 12(2), etc., to form a space 11, allowing the multi-functional integrated vehicle 1 to be moved to the pole-erection site with the pole-erection equipment stored in the space 11, and the utility pole 18 to be installed. This means that the pole-erection work, including the transportation of pole-erection equipment, can be performed by a single multi-functional integrated vehicle 1. Therefore, there is no need to prepare a separate vehicle for transporting pole-erection equipment.

[0050] In the above embodiment, when the rotating link section 13 is located above the cargo bed section 3, a space 11 of a predetermined height H1 is formed above the floor plate 8 and between the support section 9 and the rear wall 10, and an example was described in which this space 11 is formed continuously below the rotating link section 13 and below the utility pole 18. In this case, the width W1 in the vehicle width direction of the space 11, which is a roughly rectangular parallelepiped, is approximately the same width as the cargo bed section 3.

[0051] Here, as shown in Figure 11, the multi-functional integrated vehicle can lower the grapple 15 below the utility pole 18 placed on the support 9, enabling the loading and unloading of heavy objects. The multi-functional integrated vehicle 31 relaxes the restriction on the rotation of the third link 12(3) by the second cylinder CL2, allowing the grapple 15 to be lowered below the utility pole 18, and a space of a predetermined height H1 is not formed below the rotating link section 13. However, by restricting the rotation of the second link 12(2), etc., a space of a predetermined height H1 is formed below the utility pole 18, similar to the embodiment described above. In this case, the width of the space of the predetermined height H1 is smaller than the W1 described above.

[0052] Furthermore, when the utility pole 18 is not resting on the support section 9, the rotation of the second link 12(2), etc., is not restricted, and by controlling the first link 12(1) to the fifth link (5), the grapple 15 can be moved to any position above the floor plate 8, making it possible to load heavy objects into and out of the space 11 (length L1, height H1, width W1).

[0053] In the above embodiment, an example was described in which the rear of the utility pole 18 is supported by an engaging jig 19 placed on an item (not shown) stored in the space 11. However, the configuration is not limited to this, and as shown in Figure 11, the multi-functional integrated vehicle 31 may be configured so that the utility pole 18 can be placed horizontally by making the height of the rear wall 10 the same as the height of the support part 9 and providing a recess for engaging the utility pole 18 at the upper end of the rear wall 10 (for example, a recess similar to the first recess 17(1) and the third recess 17(3) of the support part 9).

[0054] (Variation 1) For example, in a multi-functional integrated vehicle, as shown in Figure 12, a space of a predetermined height H1 may not be formed below the utility pole 18, and a space of a predetermined height H1 may be formed only below the rotating link section 13. In this case, the width of the space of a predetermined height H1 is smaller than the above W1.

[0055] Furthermore, as shown in Figure 12, the multi-functional integrated vehicle may be configured such that the front of the utility pole 18 engages with the support portion 9 and the rear end of the utility pole 18 is locked to the rear wall 10. In this case, no space of a predetermined height H1 is formed below the utility pole 18. However, similar to the above embodiment, a space of a predetermined height H1 is formed below the rotating link portion 13.

[0056] (Modification 2) The multi-functional integrated vehicle may be a multi-functional integrated vehicle 33 in which a base 4 on which a boom 5 is provided is fixed to the front of the cargo bed 3, as shown in Figure 13. In this case, a space 11 of a predetermined height H1 is formed below the rotating link section 13 and in the middle and rear of the cargo bed 3. Equipment for pole erection work, such as an excavation device unit 21, can be placed in the space 11.

[0057] [Second Embodiment] In the first embodiment, an example was described in which a space of a predetermined height H1 is formed below the rotating link section 13 and below the utility pole 18. However, in the multi-functional integrated vehicle according to the second embodiment, as shown in Figure 14, a space of a predetermined height H1 does not necessarily have to be formed below either the rotating link section 13 or the utility pole 18. However, because it has a support section 9 and a multi-joint boom 5, the utility pole 18 can be transported and installed by a single multi-functional integrated vehicle 34.

[0058] The multi-functional integrated vehicle of the second embodiment may be a multi-functional integrated vehicle 34 in which, for example, as shown in Figure 14, a base 4 on which the boom 5 is erected is provided near the center of the cargo bed 3. The multi-functional integrated vehicle 32 does not have space to store large pole erection equipment. However, since the multi-functional integrated vehicle 34 can engage the front of the utility pole 18 with the support part 9 and lock the rear end of the utility pole 18 to the rear wall 10, the transport and installation of the utility pole 18 can be performed by a single multi-functional integrated vehicle 34.

[0059] The above describes an example of a multi-functional integrated vehicle and a method for installing a columnar body using drawings, but the present invention is not limited to what has been described above. For example, the shape of the space 11 is not limited to a rectangular parallelepiped as long as it can accommodate equipment and materials for pole erection work. Also, the support part 9 on which the utility pole 18 is placed may be equipped with reinforcing members. [Explanation of symbols]
