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 hardware processor,
wherein the hardware processor 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 determining that an overturning moment to turn over the traveling body or the turning body generated by a change in, moment caused by an aerial movement of the attachment has exceeded a predetermined threshold.
