- the operation unit 5b may be displayed as a GUI (Graphical User Interface) widget on the display unit 5a.
- GUI Graphic User Interface
- the display unit 5a displays the operation unit 5b as a widget, for example.
- the operation unit 5b may function as a touch panel included in the display unit 5a.
- Each of the plurality of operation levers 6 receives operations from the operator of the shovel 100.
- the operating lever 6 is an operating member for operating the excavator 100 .
- An operation signal is input to the second control valve 7 in response to the operation of the operation lever 6 by the operator of the excavator 100 .
- the second control valve 7 supplies pressure oil corresponding to the amount of operation of the operating lever 6 to the working portion 8 to operate the working portion 8 .
- FIG. 6 is a side view showing the excavator 100 from the right side.
- the revolving body 10 revolves around the revolving axis AX with respect to the traveling body 9 . Specifically, the revolving body 10 revolves with the rotary connecting member 14 with respect to the traveling body 9 . That is, the turning axis AX is substantially the same as the central axis of the rotary connecting member 14 .
- the rotary connecting member 14 is used, for example, as an oil passage between the revolving body 10 and the traveling body 9 .
- the rotary connecting member 14 includes, for example, a swivel joint.
- the receiving section 3 is arranged between the turning axis AX and the rear end 10b of the turning body 10 . Specifically, in the longitudinal direction of the revolving body 10, it is arranged between the revolving axis AX and the rear end 10b. Therefore, it is possible to prevent the receiving section 3 from coming into contact with an obstacle positioned behind the revolving body 10 . As a result, the safety of the excavator 100 can be further enhanced.
- the receiver 3 is arranged in the rear portion of the cabin 11 . Therefore, it is possible to prevent the operator of the shovel 100 from blocking the front or side field of view by the receiving unit 3 .
- the receiver 3 projects from the cabin 11 to the right of the revolving body 10 .
- the receiver 3 may protrude from the cabin 11 in the left direction of the revolving body 10 . That is, the receiver 3 protrudes from the cabin 11 to the left or right of the revolving body 10 . Therefore, the plate member 11f positioned on the back portion 11B of the cabin 11 and the receiving portion 3 do not overlap in the front-rear direction of the revolving body 10. As shown in FIG.
- the upper end 3u of the receiver 3 is positioned below the upper end 11d of the cabin 11, for example.
- the height of the upper end 3u of the receiver 3 may be substantially the same as the height of the upper end 11d of the cabin 11, for example. That is, the height of the upper end 3u of the receiving portion 3 is substantially the same as the height of the upper end 11d of the cabin 11, or the upper end 3u of the receiving portion 3 is located below the upper end 11d of the cabin 11. Therefore, it is possible to prevent the receiver 3 from contacting an obstacle located above the upper end 11 d of the cabin 11 . As a result, the safety of the excavator 100 can be further enhanced.
- the receiver 3 is located at a height where wireless communication between the receiver 3 and the reference station 200 (see FIG. 1) is not blocked by obstacles and at a position higher than the hood 15 .

- the length L2 of the running body 9 is also called the full length of the running body 9, for example. Therefore, even when the revolving body 10 revolves around the revolving axis AX, the receiving part 3 arranged between the revolving body 10 and the revolving body 10 is positioned outside the traveling body 9. It is possible to suppress contact with a positioned obstacle. As a result, the safety of the excavator 100 can be further enhanced.
- the length L1 of the revolving body 10 is equal to or less than the full width L3 of the running body 9 along the traveling direction of the running body 9, that is, the direction (lateral direction D2) substantially orthogonal to the longitudinal direction D1.
- the full width L3 is, for example, the length in the lateral direction D2 from the outer edge along the longitudinal direction D1 of the crawler 9a to the outer edge along the longitudinal direction D1 of the crawler 9b. Therefore, even when the revolving body 10 revolves around the revolving axis AX, the receiving part 3 arranged between the revolving body 10 and the revolving body 10 is positioned outside the traveling body 9. Contact with the obstacle located can be further suppressed. As a result, the safety of the excavator 100 can be further enhanced.

- the control unit 1a and the first control valve 1b are arranged along the longitudinal direction of the revolving body 10 inside the housing 1c.
- the control unit 1a is arranged in front of the first control valve 1b. Therefore, it is possible to prevent the control unit 1 from becoming large in the horizontal direction of the revolving body 10 .
- the control unit 1 can be miniaturized.
- the height of the control portion 1a is, for example, smaller than the height of the first control valve 1b.
