Patent attributes
A construction machine includes a hydraulic actuator and a processor. The processor is configured to detect a predetermined object present within a predetermined area around the construction machine, impose a motion restriction on the construction machine by decreasing the flow rate of hydraulic oil supplied to the hydraulic actuator, in response to detection of the object present within the predetermined area, and relax or cancel the motion restriction by increasing the flow rate to a level lower than before a start of the motion restriction or a level substantially same as before the start of the motion restriction, in response to a predetermined operation for relaxing or canceling the motion restriction being performed or in response to the object being no longer detected within the predetermined area, after the start of the motion restriction.
