WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/196145
Kind Code:
A1
Abstract:
This work machine comprising a front work device comprises a state amount detection device which detects a state amount relating to an operating state of the work device, and a control device which controls the operation of the work machine on the basis of an operation signal transmitted from a remote device by radio communication. The control device assesses a communication status of the radio communication and, when restricting the operation of the work machine on the basis of a result of the assessment, eases the restriction on the operation of the work machine, depending on a detection result from the state amount detection device. As a result, it is possible to restrict operation, as appropriate, on the basis of a communication status, while suppressing a deterioration in working properties.
