The present invention provides a work machine in which load shaking of a crane in emergency can be prevented. In the work machine, a turning body is disposed to be turnable relative to a base body. The work machine includes a drive control unit which controls a turning operation of the turning body, and a detection unit which detects an obstacle present around the turning body. The drive control unit does not start turning of the turning body in a case where the obstacle is detected by the detection unit while the turning of the turning body is stopped, and maintains the turning of the turning body for at least a predetermined period in a case where the obstacle is detected by the detection unit during the turning of the turning body.

Work machine collision safety controls and warnings

A dismantling system includes a dismantling machine including a tip attachment for dismantling an object to be dismantled, an imaging device that provides a field of view from a second viewpoint position for visually recognizing an object to be dismantled, which is different from a first viewpoint position of an operator, and a dismantling operation device that receives operation by an operator of the tip attachment for dismantling an object to be dismantled with respect to the field of view provided by the imaging device.

Dismantling system

An obstacle detection device capable of appropriately setting an area for detecting an obstacle in the vicinity of a machine body of a construction machine in consideration of the state of inclination of the construction machine with respect to its surrounding ground area includes an inclination information acquisition section to obtain inclination information of the machine body with respect to a surrounding ground area in the vicinity of the construction machine, and an area setting section to set a monitoring area for detecting an obstacle, and to modify the monitoring area according to the inclination information.

Obstacle detection device of construction machine

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.

Working machine

A construction machine includes a vehicle body having, a moving section, a driving mechanism, a manipulation device that receives a manipulation, a controlling unit, a manipulation detecting unit that detects the manipulation given to the manipulation device, and an obstacle detecting device that detects an obstacle in a periphery of the vehicle body. The controlling unit executes emergency-stop-processing and continuous-stop-processing. The emergency-stop-processing is executed to stop the operation of the moving section regardless of a signal from the manipulation detecting unit upon detection of the obstacle by the obstacle detecting device when the controlling unit controls the driving mechanism to drive the moving section. The continuous-stop-processing is executed to keep the operation of the moving section stopped when the obstacle detecting device does not detect the obstacle and the manipulation detecting unit detects manipulation when the operation of the moving section is stopped by the emergency-stop-processing.
