Abstract

A construction machine includes an image capturing device configured to capture an image of the surroundings, an image display part mounted in an operator'"'"'s cab and configured to display a menu screen showing an operating condition and various settings, or the captured image captured with the image capturing device, an operation part including a menu switch to cause the menu screen to be displayed on the image display part, and a detector configured to detect whether a work element is enabled or disabled. The image display part is configured to display a warning in response to the menu switch being operated while the work element is enabled.

Claims

1. A construction machine, comprising:

an image capturing device configured to capture an image of surroundings;

an image display part mounted in an operator'"'"'s cab and configured to display a menu screen showing an operating condition and various settings, or the captured image captured with the image capturing device;

an operation part including a menu switch to cause the menu screen to be displayed on the image display part; and

a detector configured to detect whether a work element is enabled or disabled,

wherein the image display part is configured to display a warning in response to the menu switch being operated while the work element is enabled.

2. The construction machine as claimed in claim 1, wherein the image display part is configured to display the menu screen together with the warning in response to the menu switch being operated while the work element is enabled.

3. The construction machine as claimed in claim 1, wherein the image display part is configured to display the warning together with the captured image in response to the menu switch being operated while the work element is enabled.

4. The construction machine as claimed in claim 3, wherein the image display part is configured to display the menu screen together with the warning in response to the menu switch being operated while the warning is displayed together with the captured image.

5. The construction machine as claimed in claim 1, wherein the image display part is configured to clear the warning and display the menu screen in response to the work element becoming disabled while the warning is displayed.

6. The construction machine as claimed in claim 1, further comprising:

a control valve configured to control hydraulic oil supplied to the work element that is a hydraulic actuator driven with the hydraulic oil discharged from a hydraulic pump,

an operation apparatus connected to a pilot pump via a pilot line to supply the hydraulic oil supplied from the pilot pump to the control valve at a hydraulic pressure commensurate with an amount of operation;

a shutoff valve provided in the pilot line and configured to interrupt transmission of the hydraulic oil from the pilot pump to the operation apparatus; and

a gate lock apparatus configured to control the shutoff valve in accordance with an operation of a gate lock lever,

wherein the detector is configured to detect whether the hydraulic actuator is enabled or disabled based on an operation of the gate lock lever.

7. The construction machine as claimed in claim 1, wherein the image display part is configured to preferentially display the captured image when the work element is enabled.

8. The construction machine as claimed in claim 1, wherein the image display part is configured to display the captured image independently of a traveling direction of a lower-part traveling body.

9. A method of controlling a construction machine to control an image displayed on an image display part mounted in an operator'"'"'s cab of the construction machine, the construction machine including an image capturing device configured to capture an image of surroundings, comprising:

detecting whether a work element is enabled or disabled in response to a menu switch to cause a menu screen to be displayed on the image display part being operated, the menu screen showing an operating condition and various settings; and

displaying a warning on the image display part in response to the menu switch being operated while the work element is enabled.

10. The method of controlling a construction machine as claimed in claim 9, wherein said displaying displays the menu screen on the image display part together with the warning.

11. The method of controlling a construction machine as claimed in claim 9, wherein said displaying displays the warning on the image display part together with the captured image captured with the image capturing device.
