Summary:To provide a work machine capable of improving safety of a surrounding worker while suppressing a decrease in workability of a machine operator.SOLUTION: A control device 2: identifies a specific actuator to be an object of operation restriction from a request signal (restriction request) received by a communication terminal 8; finally determines acceptability of the operation restriction of the specific actuator according to approval acceptability information of the operation restriction of the specific actuator and (current) operation state information of the specific actuator of a work machine 100; restricts the operation of the corresponding specific actuator when determining that the operation restriction of the specific actuator is possible; and notifies an external terminal 1 of the operation restriction state of the specific actuator via the communication terminal 8.SELECTED DRAWING: Figure 3 【課題】機械操作者の作業性低下を抑えながら周囲作業者の安全性を向上させることのできる作業機械を提供する。【解決手段】制御装置2は、通信端末8が受信した要求信号（制限要求）から動作制限の対象となる特定のアクチュエータを識別し、作業機械100の特定のアクチュエータの動作制限の承認可否情報、および特定のアクチュエータの（現在の）動作状態情報に応じて、特定のアクチュエータの動作制限の可否を最終的に判定し、特定のアクチュエータの動作制限を可能と判定した場合、対応する特定のアクチュエータの動作を制限するとともに、特定のアクチュエータの動作制限状態を通信端末8を介して外部端末1に通知することを特徴とする。【選択図】図３
