Abstract
Provided is a work machine that can suppress decrease in work efficiency while reducing the possibility of contacting a worker or a dump truck, etc. A movement range is set in advance so as to avoid entry of a worker or a dump truck, etc. into the set movement range. The work machine performs stop control with clearance for an obstacle having entered the movement range, but performs stop control with relatively small clearance (minimum clearance) for a movement range. Thus, the work machine can reduce the frequency of stopping a body or a work implement and suppress decrease in work efficiency. Since the work machine controls the body or the work implement to stop with clearance when the worker or the dump truck, etc. enters the movement range of the work machine, the work machine can reduce the possibility of contacting the worker or the dump truck, etc.
