Document Type and Number:
WIPO Patent Application WO/2019/155843
Kind Code:
The purpose of the invention is to provide an excavator that allows shock to a vehicle body to be suppressed when a jacked-up state is cancelled. For this purpose, this excavator comprises: a lower traveling body 1; an upper turning body 3 mounted on the lower traveling body 1 so as to freely turn; an attachment, which includes a boom 4, an arm 5, and a bucket 6, mounted to the upper turning body 3; and a controller 30. The controller 30 slows down attachment movement relatively when the excavator is in a jacked-up state.
