Abstract
To provide a working machine including a lower travelling body and an upper slewing body disposed in a slewable manner with respect to the lower travelling body, the working machine being capable of more reliably preventing the upper slewing body from coming into contact with an obstacle existing around the working machine. The working machine includes a detection device, a position identification device, and a movement control device. The position identification device includes a calculation section, a conversion section, and an identification section. The movement control device controls the movement of the upper slewing body in such a way as to prevent the upper slewing body from coming into contact with the obstacle based on the position of the obstacle relative to the virtual boundary surface, the position being identified by the identification section.
