PROBLEM TO BE SOLVED: To provide a work attachment control device of a construction machine capable of easily and reliably suppressing the interference of an end attachment with a cabin without inputting data such as the dimensions of a boom and the like. SOLUTION: This control device 1 of a hydraulic shovel including a work attachment with a main boom section, an arm, and a bucket includes boom and arm angle sensors 11, 13, a controller 9, a mode selector switch 21, and a storage instruction switch 23. The controller 9 stores the detection values of the boom and arm angle sensors 11, 13 as the detected points at the time of setting ofΘb-Θa coordinate system when the storage instruction switch 23 is operated while the initial adjusting mode is set, and based on three detected points at the time of setting, a first stop curve which separates a safe area and a risk area from each other is calculated. The controller 9 prohibits the operation of a bucket to the cab side when a detected point during the operation is present near the first stop curve. COPYRIGHT: (C)2011,JPO&INPIT
