In the hydraulic excavator, the control unit outputs the drive signals, which gives the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device to the work implement operating lever, the right work implement operating lever and the traveling lever, to the drive section. The control section outputs the control signals based on the motion of the left work implement operating lever the right work implement operating lever or the traveling lever operated by the operator when the motion of the left work implement operating lever, the right work implement operating lever or the traveling lever operated by the operator is different from the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device.

A work machine periphery monitoring system includes a display control unit that causes a display unit to display an image indicating a periphery of a work machine and a guide line arranged in at least a part of the periphery of the work machine in the image. The display control unit switches a display state of the guide line between a valid state in which an alarm is output when an object is present around the work machine and an invalid state in which no alarm is output.

Provided is a construction machine that avoids automatic release of operation restriction involving, for example, sudden acceleration unintended by an operator even when an inclined angle of a vehicle body changes. The construction machine includes a vehicle body 50 configured to operate, 3D sensors (obstacle detection devices) 5, 6, 7, and 8 that detect an obstacle present around the vehicle body 50, an inclined angle determination device (an inclined angle detection device) 9 that detects the inclined angle of the vehicle body 50, and a vehicle body controller (a controller) 14 having an operation restriction function that performs a restriction control to restrict an operation of the vehicle body 50 when the 3D sensors (the obstacle detection devices) 5, 6, 7, and 8 detect an obstacle. When the inclined angle of the vehicle body 50 exceeds a predetermined threshold while the restriction control is not performed with the operation restriction function, the vehicle body controller (the controller) 14 disables the operation restriction function. When the inclined angle of the vehicle body 50 exceeds the predetermined threshold while the restriction control is performed with the operation restriction function, the vehicle body controller (the controller) 14 does not disable the operation restriction function.

A hydraulic excavator includes: operation devices that output, based on operation by an operator, operation signals to operate a lower travel structure, an upper swing structure, and a front work implement; solenoid valves 23a, 23b, 24a, and 24b that limit the operation signals outputted from the operation devices; and a controller that controls the solenoid valves based on detection signals from sensors, and that detect objects in the surroundings of a machine body. The detection ranges of the sensors, and include a first detection range TR defined based on travel performance of the lower travel structure and a second detection range SW defined to be along a swing radius of a rear end of the upper swing structure. As a result, the influence of excessive alarm on the working operator can be reduced while enhancing detection accuracy by setting the detection range according to action range of the work machine.
