Hydraulic excavator
A hydraulic excavator includes a plurality of cameras that are attached to an upper swing structure and photograph images of surroundings, a controller configured to detect an obstacle present around the upper swing structure on the basis of the camera images, and a speaker that makes a notification that the obstacle is detected when the controller detects the obstacle. When a lock lever is at a lock release position and control levers are maintained in a non-operating state from a time of a start of the controller, the controller permits the notification by the speaker. When the lock lever is at the lock release position and the control levers are changed from an operating state to a non-operating state, the controller permits the notification by the speaker when the non-operating state is continued for a predetermined time or more.
