Abstract

A shovel includes a lower traveling body, an upper rotating body rotatably mounted on the lower traveling body, a cab mounted on the upper rotating body, a left monitor mounted on a left pillar inside the cab, a right monitor mounted on a right pillar inside the cab, a left camera configured to capture an image of an area on a left side of the upper rotating body, a right camera configured to capture an image of an area on a right side of the upper rotating body, and a controller configured to control both the left monitor and the right monitor. The controller is configured to cause the left monitor to continuously display a mirror image generated from the image captured by the left camera, and to cause the right monitor to continuously display a mirror image generated from the image captured by the right camera.

Claims

1. A shovel comprising:

a lower traveling body;

an upper rotating body rotatably mounted on the lower traveling body;

a cab mounted on the upper rotating body;

a left monitor mounted on a left pillar inside the cab;

a right monitor mounted on a right pillar inside the cab;

a left camera configured to capture an image of an area on a left side of the upper rotating body;

a right camera configured to capture an image of an area on a right side of the upper rotating body; and

a controller configured to control both the left monitor and the right monitor,

wherein the controller is configured to cause the left monitor to continuously display a mirror image generated from the image captured by the left camera, and to cause the right monitor to continuously display a mirror image generated from the image captured by the right camera.

2. The shovel according to claim 1, wherein the left monitor and the right monitor are mounted at a same height relative to a reference horizontal surface.

3. The shovel according to claim 1, wherein a screen size of each of the left monitor and the right monitor is at least 7 inches.

4. The shovel according to claim 1, further comprising:

a back monitor mounted on an upper portion of the right pillar so as to be disposed along a front side ceiling frame inside the cab; and

a back camera configured to capture an image of an area on a rear side of the upper rotating body,

wherein the controller is configured to cause the back monitor to continuously display a mirror image generated from the image captured by the back camera.

5. The shovel according to claim 1, wherein a mounting height of each of the left camera and the right camera is between a height of a platform of the upper rotating body and a height of an upper surface of the cab.

6. The shovel according to claim 1, wherein a horizontal angle of view of each of the left camera and the right camera is 20 to 70 degrees.

7. The shovel according to claim 1, further comprising,

a mechanism configured to adjust a direction of each of a plurality of cameras including the left camera and the right camera,

wherein the mechanism is operated through an operating device disposed inside the cab.

8. The shovel according to claim 1, wherein the controller is configured to adjust a range displayed on each of the left monitor and the right monitor in accordance with an operation through an operating device disposed inside the cab.
