Abstract
A shovel includes a lower traveling body, and an upper swiveling body mounted on the lower traveling body. The upper swiveling body is rotatable. An attachment is attached to the upper swiveling body. A traveling actuator is configured to drive the lower traveling body. An attachment actuator is configured to move the attachment. A control device is provided in the upper swiveling body. The control device is configured to autonomously operate at least one of the traveling actuator and the attachment actuator depending on an inclination of a ground on which the lower traveling body is traveling.
Claims7
A control device for a shovel, the shovel including:
- a lower traveling body;
- an upper swiveling body rotatably mounted on the lower traveling body;
- an attachment attached to the upper swiveling body, the attachment including a bucket;
- a traveling actuator configured to drive the lower traveling body;
- and an attachment actuator configured to move the attachment, the control device comprising:
- processing circuitry configured to, while the shovel is approaching an ascending slope,
- autonomously determine whether a horizontal distance between the bucket and a lower end of the ascending slope is less than a predetermined distance, the horizontal distance being measured perpendicular to a direction of gravity, and
- autonomously operate the attachment actuator to maintain a height of the bucket at a predetermined value in response to determining that the horizontal distance is less than the predetermined distance.
A control device for a shovel, the shovel including:
- a lower traveling body;
- an upper swiveling body rotatably mounted on the lower traveling body;
- an attachment attached to the upper swiveling body, the attachment including a bucket;
- a traveling actuator configured to drive the lower traveling body;
- and an attachment actuator configured to move the attachment, the control device comprising:
- processing circuitry configured to, while the shovel is ascending a slope,
- autonomously determine whether the bucket has passed an upper end of the slope based on a horizontal distance between the bucket and the upper end of the slope, the horizontal distance being measured perpendicular to a direction of gravity,
- autonomously operate the attachment actuator to lower the bucket in response to determining that the bucket has passed the upper end of the slope,
- autonomously determine, after lowering the bucket, whether a counterweight of the shovel is lifted as a front end of the lower traveling body protruding in air is lowered, and
- autonomously operate the attachment actuator to raise the bucket in response to determining that the counterweight is lifted.
