Abstract
A shovel includes a lower traveling body; an upper turning body turnably mounted on the lower traveling body; an attachment mounted on the upper turning body; and a control device including a memory storing a program and a processor configured to execute a process including automatically decelerating or stopping turning of the upper turning body when interference between the attachment and a control reference surface is predicted while the upper turning body is turning.
Claims18
A shovel comprising:
- a lower traveling body;
- an upper turning body turnably mounted on the lower traveling body;
- an attachment mounted on the upper turning body, the attachment including a bucket;
- and
- a control device including a memory storing a program and a processor coupled to the memory and configured to, while the upper turning body is turning,
- determine whether a turning trajectory followed by a predetermined point of the bucket intersects a design surface on condition that the upper turning body continues turning toward the design surface,
- automatically decelerate or stop the turning of the upper turning body in response to determining that the turning trajectory intersects the design surface, and
- automatically stop the turning of the upper turning body when the upper turning body faces the design surface, in response to determining that the turning trajectory does not intersect the design surface.
A shovel control device for controlling a shovel, the shovel including a lower traveling body, an upper turning body turnably mounted on the lower traveling body, and an attachment attached to the upper turning body, the attachment including a bucket, the shovel control device comprising:
- a memory storing a program and a processor coupled to the memory and configured to, while the upper turning body is turning,
- determine whether a turning trajectory followed by a predetermined point of the bucket intersects a design surface on condition that the upper turning body continues turning toward the design surface,
- automatically decelerate or stop the turning of the upper turning body in response to determining that the turning trajectory intersects the design surface, and
- automatically stop the turning of the upper turning body when the upper turning body faces the design surface, in response to determining that the turning trajectory does not intersect the design surface.
