A control device for a work machine is a device for controlling a working unit of a work machine to excavate an object to be excavated. The control device includes a control unit for controlling the working unit to prevent a working implement of the working unit from crossing a predetermined target profile, and a switching unit for defining the target profile as an offset profile separated by a predetermined distance from a target excavation profile that is a target profile for finishing of the object to be excavated or the target excavation profile, based on an attitude of the working implement relative to the target excavation profile.

Methods and systems for operating an industrial machine. One system includes a controller that includes an electronic processor. The electronic processor is configured to calculate an eccentricity of a center of gravity of the industrial machine with respect to a center of a bearing propelling the industrial machine and calculate a ground pressure associated with the bearing based on the eccentricity of the center of gravity.

An area limiting excavation control system for construction machines including a control unit (9) that performs area limiting control by controlling at least one of a plurality of hydraulic cylinders (3a, 3b, 3c) on the basis of a posture and a position of each of a boom (1a), an arm (1b), and a bucket (1c). The control system includes an angle sensor group (8) that detects rotational angles of the boom (1a), the arm (1b), and the bucket (1c), and a tilting angle sensor group (81) that detects ground angles of the boom (1a), the arm (1b), and the bucket (1c). The control unit (9) selects, from among the angle sensor group (8) and the tilting angle sensor group (81), a sensor to be used for calculating a posture and a position of each of the boom (1a), the arm (1b), and the bucket (1c) in accordance with a magnitude of speed of at least one of the boom (1a), the arm (1b), and the bucket (1c).

A work implement includes a breaker. Sensors detect an attitude of the work implement. A pilot valve controls the operation of the breaker. A controller controls the pilot valve. The controller detects, from the attitude of the work implement obtained by the sensors, a distance between a tip of the breaker and a striking limit. When it is determined that the tip of the breaker has reached the striking limit, the controller controls the pilot valve to stop the operation of the breaker.

There is provided a construction machine that achieves both safety and operability by lowering the possibility of an accident due to contact between the construction machine and a worker in the periphery of a vehicle body while securing operability in situations where an object required for work is present in the periphery. A controller has a normal mode as a control mode for making the operation limiting control effective and a temporary cancelation mode as a control mode for temporarily canceling the operation limiting control. The controller shifts to the temporary cancelation mode in response to operation of the control canceling device while in the normal mode. The controller shifts back to the normal mode in a case where a predetermined condition not responsive to operation of the control canceling device is satisfied while in the temporary cancelation mode.

To provide a work machine that makes it possible to drive actuators faster and more accurately by supplying flows to the actuators accurately at target rates without depending on load variations in a case where the machine body is controlled automatically by command inputs of a controller, while high operability is ensured for manual operation by an operator. In a case where a machine control function is cancelled via a machine control switch, a controller cancels limitation of the flow rate of a hydraulic fluid supplied to a plurality of directional control valves, the limitation being performed by the auxiliary flow rate control devices, and in a case where the machine control function is selected via the machine control switch, the controller causes the auxiliary flow rate control devices to limit the flow rate of the hydraulic fluid supplied to the plurality of directional control valves.
