Abstract
A controller (30) of an excavation system controls a bucket (15c) to excavate an excavation object (O) along an excavation row (C). In a case where the bucket (15c) is located forward (X1) of a border (53) at completion of one excavation performed by the bucket (15c), the controller (30) causes the bucket (15c) to perform next excavation without changing the excavation row (C). In a case where the bucket (15c) is located on the border (53) or rearward (X2) of the border (53) at the completion of one excavation performed by the bucket (15c), the controller (30) changes the excavation rows (C) and causes the bucket (15c) to perform the next excavation.
Claims2
The excavation system comprising:
- a lower travelling body;
- an upper slewing body slewably mounted on the lower travelling body;
- an attachment attached to the upper slewing body, the attachment having a bucket that excavates an excavation object;
- and
- a controller,
- wherein the controller sets a border at a position spaced forward with respect to the upper slewing body,
- the controller controls the bucket to automatically excavate the excavation object in a direction of approaching the upper slewing body along an excavation row extending in a front-rear direction of the upper slewing body,
- the controller causes the bucket to perform next excavation without changing the excavation row in a case where the bucket is located forward of the border at completion of one excavation by the bucket, and
- the controller changes the excavation row and causes the bucket to perform the next excavation in a case where the bucket is located on the border or rearward of the border at the completion of one excavation by the bucket.
