Abstract
A shovel that corrects the movement of an attachment regardless of the operating state of the attachment by an operator is provided. The shovel includes a traveling body, a turning body turnably mounted on the traveling body, an attachment attached to the turning body, a hydraulic actuator configured to drive the attachment, and a controller. The controller is configured to control the hydraulic actuator to minimize a change in orientation of the traveling body or of the turning body, in response to a change in moment caused by an aerial movement of the attachment.
