- the camera 15B can also be supported by a support arm.
- the display through the hidden part is a portion where a person or the like may enter, for example, a person such as a ground contact surface of a crawler track may enter. Therefore, the height position and the protruding length of the support arm 40 to which the camera 15 is attached are appropriately set based on the position and spread of the hidden portion where the transparent display needs to be performed. It ’s fine.
- the excavator 1 performs work such as excavation of earth and sand, and the front work machine 5 operates.
- the front work machine 5 since the bucket provided at the tip of the machine operates so as to cut from the upper side toward the earth and sand, if a person or an object is located in the movable trajectory range of the bucket, There is a possibility of collision. It is necessary to protect the front work machine 5 from colliding with a person or an object during this work. Of course, the movement of the front work machine can be visually recognized by the operator boarding the cab 4. Therefore, as shown in FIG. 10, in the reach range of the front work machine 5, the range in which the bucket may be grounded is displayed on the monitor 20 as the excavable range B.
- the front work machine 5 is provided in the upper swing body 3, and when the upper swing body 3 is turned, the front work machine 5 is also turned in synchronization. Since the monitoring cameras 15F, 15B, 15L, and 15R are also provided in the upper swing body 3, the positional relationship with respect to the front work machine 5 on the image by these cameras 15F, 15B, 15L, and 15R does not change. Accordingly, the monitor 20 displays the excavable range B where the front work machine 5 may be grounded together with the camera images 21F, 21B, 21L, and 21R centered on the icon image 21C. It is determined by the width dimension and its maximum reach length. Since there are a plurality of types of buckets having different width dimensions, it is desirable to change the excavable range B according to the configuration of the front work machine 5 actually mounted on the hydraulic excavator 12.
- the excavator 1 can be driven on the basis of the excavable range B when traveling and turning and selecting the excavation location, The position of the excavation point can be easily adjusted. Accordingly, by displaying the excavable range B on the monitor 20, not only can work safety be ensured, but work efficiency is also improved.
