Publication number: 20220364333Abstract: 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.Type: ApplicationFiled: July 8, 2020Publication date: November 17, 2022Applicant: KOMATSU LTD.Inventors: Harunobu USHIJIMA, Satoru IDE, Hiroshi YAMASHITA
