For example, the operating device 45L can operate the rotation of the machine body 2 and the swinging of the arm 13. The operating device 45R can operate the swinging of the first boom 12A and the swinging of the work tool 14. As shown in Fig. 1, the driver's section 41 has two travel levers 48L, 48R arranged in front of the driver's seat 6. The two travel levers 48L, 48R are arranged side by side in the machine body width direction K2. The left travel lever 48L can operate the first crawler travel body 3A, and the right travel lever 48R can operate the second crawler travel body 3B.

[0021] As shown in Figs. 1, 2, 3 and 4, a prime mover (engine) E1 is mounted on the rear of the aircraft body 2. A bonnet 17 is provided on the rear of the aircraft body 2 to form a prime mover chamber E2 that houses the prime mover E1. The bonnet 17 has a first side cover 17A, a second side cover 17B, a rear cover 17C, a partition member 17D, and the like. As shown in Fig. 1, the first side cover 17A covers the left side of the prime mover E1. As shown in Fig. 2, the second side cover 17B covers the right side of the prime mover E1. The rear cover 17C covers the rear of the prime mover E1. The upper part of the rear cover 17C is rotatable around an axis extending in the aircraft width direction K2 by a hinge device and can swing up and down.

As shown in FIG. 4, the second partition plate 26B is fixed to the upper part of the first partition plate 26A. The lower part of the partition wall main body 17Da of the partition wall member 17D is attached to the second partition plate 26B. The third partition plate 26C is arranged at the rear part of the mounting part 11. In detail, the mounting part 11 has a left support plate 27L arranged at the left end part of the mounting part 11 and erected on the rotating base plate 29, and a right support plate 27R arranged at the right end part of the mounting part 11 and erected on the rotating base plate 29, and the third partition plate 26C is provided across the support plates 27L and 27R at the rear part of the left support plate 27L and the right support plate 27R. The first partition plate 26A and the second partition plate 26B are disposed to the left of the support plate 27L. The base of the first boom 12A and the lower end side of the boom cylinder 19A are pivotally supported between the support plate 27L and the support plate 27R.

[0023] 1, 2 and 4, the weight 10 constitutes the rear part of the fuselage 2. The weight 10 is attached to the rear part of the rotating base plate 29. As shown in Figs. 4 and 5, a support frame 30 is provided inside the engine room E2 to support the bonnet 17 and the devices and parts inside the engine room E2. The support frame 30 is mounted on the aircraft body 2. More specifically, the support frame 30 has a left front leg 31L, a right front leg 31R, a left rear leg 32L, a right rear leg 32R, and a top plate 33. The left front leg 31L is attached to a fixed member 34A fixed to the first partition plate 26A. The right front leg 31R is attached to the support plate 27R via a mounting member 34B. The left rear leg 32L is attached to a fixed member 34C fixed to the rotating base plate 29. The right rear leg 32R is attached to a fixed member 34D fixed to the rotating base plate 29. The top plate 33 is disposed so that the plate surface faces the up-down direction and is disposed across the upper parts of the right front leg 31R and the right rear leg 32R and the upper parts of the left front leg 31L and the left rear leg 32L. The top plate 33 is also fixed to the upper parts of the left front leg 31L, the right front leg 31R, the left rear leg 32L, and the right rear leg 32R by welding or the like.

[0024] As shown in Fig. 5, the canopy 5 has a mounting frame 35 provided across the lower part of the first rear support pillar 22B and the lower part of the second rear support pillar 22C. The mounting frame 35 is attached to the support frame 30. This supports the rear part of the canopy 5. The lower part of the front support pillar 22A is attached to the support plate 27L via a stay 36. This supports the front part of the canopy 5.

[0025] 5 and 6, the mounting frame 35 has a base member 37 and a vertical plate 38. The base member 37 is formed from a plate material and is arranged so that the plate surface faces up and down and spans the lower end of the first rear support column 22B and the second rear support column 22C. The lower end of the first rear support column 22B is fixed to the upper surface of the left part of the base member 37 by welding or the like, and the lower end of the second rear support column 22C is fixed to the upper surface of the right part of the base member 37 by welding or the like.

[0026] The base member 37 is attached to the top plate 33 of the support frame 30 via vibration-isolating members 39. In detail, as shown in Fig. 4, the base member 37 is disposed above the upper wall portion 17Db of the partition member 17D, and the vibration-isolating members 39 are placed on the top plate 33 and pass through the upper wall portion 17Db to abut against the lower surface of the base member 37. Therefore, the base member 37 is supported in a vibration-isolating manner by the top plate 33. The base member 37 is fixed to the top plate 33 by bolt members 40 which pass through the base member 37 and the vibration-isolating members 39 from above and are screwed into the top plate 33.

[0027] 6, the vertical plate 38 is disposed between the lower parts of the first rear support column 22B and the second rear support column 22C with its plate surface facing the front-rear direction K1, and is erected on the base member 37. The vertical plate 38 is fixed to the base member 37, the first rear support column 22B, and the second rear support column 22C by welding or the like. The vertical plate 38 has a main plate portion 38a erected on the base member 37, and an upper wall portion 38b extending forward from an upper end of the main plate portion 38a.

[0028] As shown in Fig. 3, the work machine 1 is equipped with a communication unit 58. The communication unit 58 is disposed behind the console 44R. More specifically, the communication unit 58 is disposed behind the driver's seat 6 on the other side (right side) of the driver's seat 6 in the vehicle body width direction K2. In other words, the communication unit 58 is disposed to the right of the center of the driver's seat 6 in the vehicle body width direction K2 and behind the driver's seat 6, and is partially overlapped on the right side of the driver's seat 6 in a rear view (see Fig. 7). The communication unit 58 is also disposed above the bonnet 17.

[0029] By disposing the communication unit 58 behind the console 44R, it is possible to prevent the communication unit 58 from interfering with the operator's forward visibility. In addition, since the communication unit 58 is disposed behind the driver's seat 6, the communication unit 58 does not get in the way when the operator operates the operation device 45R, the dozer lever 47, or various switches. In other words, the communication unit 58 is disposed in a position where the operator's arms, etc. do not come into contact with the communication unit 58 when operating the operation device 45R, the dozer lever 47, and various switches. In other words, the communication unit 58 is disposed in a mounting position that is easy to arrange and can ensure communication and operability of the operation device 45R, etc.

[0030] The communication unit 58 includes an information processing unit (IPU) 59 and a direct communication unit (DCU) 60. The IPU 59 is an "information processing device" that temporarily stores information about the work machine 1 and performs predetermined processing (for example, compression processing, etc.). As shown in FIG. 8, the IPU 59 is connected to a communication port of an in-vehicle communication network (not shown) or a communication port of an in-vehicle fault diagnosis device (OBD: On-Board Diagnostics) via a harness 64 and a connector 62. One of the connectors 62 is connected to the communication port of the in-vehicle communication network, and one of the other connectors 62 is connected to the communication port of the in-vehicle fault diagnosis device. The in-vehicle communication network is composed of a Controller Area Network (CAN) or FlexRay mounted on the work machine 1. The harness 64 is composed of a plurality (a large number) of electric wires (wiring) bundled together. The IPU 59 transmits and receives information about the work machine 1 from the communication network and the in-vehicle fault diagnosis device.

[0031] Further, the harness 64 branches into a branch portion 64a connected to the DCU 60, a branch portion 64b connected to the IPU 59, and a branch portion 64c connected to a fuse 68 for the DCU 60, near the communication unit 58 (IPU 59). The IPU 59 is connected to the DCU 60 via the harness 64 and transmits data to the DCU 60. The IPU 59 and the DCU 60 are connected to a power supply port (not shown) via the harness 64 and a connector 63, and power is supplied from the power supply port. The harness 64 is also provided with a connector 63 that connects the IPU 59 to a connection port of the harness (not shown) of the cabin when the communication unit 58 is provided in the work machine 1 equipped with a cabin. One of the connectors 63 is connected to the power supply port, and the other connector 63 is connected to the connection port of the harness of the cabin.

[0032] The positions of the communication ports of the on-board communication network and the on-board fault diagnosis device are different between the working machine 1 without a cabin and the working machine 1 with a cabin, but the length of the harness 64 from the communication unit 58 to the connector 62 is formed to a length that can be connected to the communication port of the on-board communication network and the on-board fault diagnosis device, regardless of whether the communication unit 58 is mounted on the working machine 1 without a cabin or the working machine 1 with a cabin. In addition, when the communication unit 58 is mounted on the working machine 1 with a cabin, the harness 64 has a connector that connects the IPU 59 to the connection port of the harness of the cabin, so that the harness 64 is a common harness 64 when the communication unit 58 is mounted on the working machine 1 with a cabin and when the communication unit 58 is mounted on the working machine 1 without a cabin. In other words, the harness 64 can be shared between the working machine 1 with a cabin mounted on the machine body 2 and the working machine 1 without a cabin mounted on the machine body 2.

[0033] The DCU 60 is a "communication device" that communicates data with external devices (not shown). The DCU 60 receives and transmits data from the IPU 59. The DCU 60 also transmits the data received from the IPU 59 and data such as location information to a server. The server is, for example, a server installed at a manufacturer (manufacturing company) that manufactures the work machine 1, or a server installed at a dealer (sales and maintenance company) that sells and maintains the work machine 1.

[0034] 7 and 8, the IPU 59 has a generally rectangular parallelepiped shape with a surface facing the front-rear direction K1 being generally rectangular, and is disposed vertically with the longitudinal direction of the parallelepiped coinciding with the up-down direction. The IPU 59 also has a generally rectangular parallelepiped shape with a width in the front-rear direction K1 (width in the thickness direction) narrower than its width in the up-down direction and its width in the aircraft width direction K2. The IPU 59 has a connection part 59a on its right side to which the harness 64 is connected.

[0035] 7 and 8, the DCU 60 has a generally rectangular parallelepiped shape with a device front surface 60A being generally rectangular, and is disposed sideways with the longitudinal direction of the parallelepiped coinciding with the body width direction K2. Also, as shown in Fig. 8, the DCU 60 has a generally rectangular parallelepiped shape with a width in the front-rear direction K1 (width in the thickness direction) narrower than its width in the up-down direction and its width in the body width direction K2. 4 and 7, the DCU 60 is disposed between the first rear support pillar 22B and the second rear support pillar 22C and at a position slightly lower than the backrest 6B of the driver's seat 6. As shown in Fig. 10, the IPU 59 is disposed below the DCU 60. More specifically, the IPU 59 is disposed below the DCU 60 and forward of the DCU 60.

[0036] Fig. 9 shows the DCU 60 as viewed from the device back side of the DCU 60 (the side opposite to the device front side 60A). As shown in Figs. 9 and 12, the DCU 60 has a case 72 and a cover 73 that covers the case 72 from the device front side 60A. The DCU 60 has a connection part 60a to which a harness 64 is connected. The connection part 60a is provided on the left side of the lower part of the case 72.

[0037] As shown in FIG. 9, the DCU 60 has an electronic board 91 housed in the case 72. The case 72 is formed in a substantially rectangular parallelepiped shape, and a communication antenna (e.g., a 3G antenna, etc.) 92 and a positioning antenna (GPS antenna) 93 are attached to the front side of the electronic board 91, where electronic components are attached. The electronic board 91 is housed in the case 72 so that the front side faces the device front surface 60A. The communication antenna 92 ​​is an antenna for communicating with a server, and is provided on the left and right parts of the electronic board 91. The communication antenna 92 ​​is built in the DCU 60. In the DCU 60 of this embodiment, since the communication antenna 92 ​​is built in the DCU 60, a communication-enabled state can be maintained when a fraudulent act such as theft (such as removing the DCU 60) is occurring, and a report can be sent to a predetermined report destination.

[0038] The positioning antenna 93 receives satellite signals transmitted from positioning satellites. The positioning antenna 93 is provided on the lower right side of the electronic board 91. The work machine 1 detects its own position (positioning information including latitude and longitude) by a positioning system based on the satellite signals received by the positioning antenna 93. In detail, the work machine 1 obtains the position and direction of the work machine 1 by using a well-known Global Positioning System (GPS), which is an example of a Global Navigation Satellite System (GNSS), (for example, by RTK-GPS suitable for positioning of moving objects). That is, the work machine 1 communicates with a base station (reference station) installed at a known position, and the base station transmits positioning data (correction information) obtained by receiving radio waves from the positioning satellite to the work machine 1. The work machine 1 detects its own position (latitude and longitude) based on the positioning data obtained by receiving radio waves from the positioning satellite and the positioning data from the base station.
