To balance safety and emergency availability.SOLUTION: A control device includes a signal input unit that inputs a signal from a first signal line connected to a first switch that detects press and release of a momentary operation push button that sets and releases a lock on the operation of the work equipment, and a second signal line connected to a second switch that is interlocked with the first switch, and a work equipment lock control unit that alternately locks and releases the operation of the work equipment when information indicating that the push button has changed from off to on to off is obtained from both the first signal line and the second signal line, and unlocks the operation of the work equipment when the information indicating that the push button has changed from off to on to off is obtained from only one of the first signal line and the second signal line and a predetermined operation is performed on a predetermined operating device of the work equipment when the operation of the work equipment is set to be locked.SELECTED DRAWING: Figure 5 【課題】安全性と非常時稼働性を両立させる。【解決手段】制御装置は、作業機の動作のロックを設定および解除するモーメンタリ動作の押しボタンの押し離しを検出する第１スイッチに接続された第１信号線から信号を入力するとともに、第１スイッチと連動する第２スイッチに接続された第２信号線から信号を入力する信号入力部と、押しボタンがオフ→オン→オフとなったこと示す情報が第１信号線と第２信号線の両方から得られた場合、作業機の動作のロックの設定と解除とを交互に切り替えるとともに、押しボタンがオフ→オン→オフとなったこと示す情報が第１信号線と第２信号線のいずれか一方のみから得られた場合、作業機の動作のロックが設定されているとき、作業機の所定の操作装置に対する所定操作が伴ってなされたときに限って、作業機の動作のロックを解除する作業機ロック制御部と、を備える。【選択図】図５
