Abstract: A work machine includes a manipulation device, a surrounding area monitoring device, and a controller. The manipulation device outputs a manipulation signal to operate the work machine. The surrounding area monitoring device serves as a device for detecting whether an object to be recognized is present or not inside a set region that is set in a surrounding area of the work machine. The controller controls the work machine. The controller is capable of switching a setting of an object sensing function between execution and non-execution, the object sensing function being to restrict movement of the work machine when it is detected that the object is present inside the set region. When the manipulation signal is detected in a state where the object sensing function is set at non-execution, the controller switches the setting of the object sensing function to execution.

Abstract: A work machine is improved in manipulability. The work machine includes a manipulation device, an actuator, a surrounding area monitoring device, and a controller. The manipulation device is manipulated to operate the work machine. The actuator drives the work machine in a manner corresponding to a manipulation of the manipulation device. The surrounding area monitoring device serves as a device for detecting whether an object to be recognized is present or not inside a set region that is set in a surrounding area of the work machine. The controller controls the work machine. When a prescribed manipulation device is manipulated in a case where it is detected that the object is present inside the set region, the controller restricts an operation of the actuator corresponding to a manipulation of the manipulation device.

Abstract: A set area is appropriately set around a work machine. A hydraulic excavator includes a surroundings monitoring apparatus that detects whether or not an object to be recognized is present within a set area set around the hydraulic excavator, a sensor that detects change in position of a traveling unit with respect to a revolving unit, and a controller that controls the hydraulic excavator. The controller sets the set area in accordance with change in position of the traveling unit with respect to the revolving unit detected by the sensor.
