制御装置。[Claims for Utility Model Registration] A control device for a work machine having a boom that can be raised and lowered around its base end and that is extendable and retractable at its distal end, comprising: a raising and lowering cylinder that raises and lowers the boom around its base end; and a telescoping cylinder that extends and retracts the tip end side of the boom, a telescoping control means that controls the operation of the telescoping cylinder, and a controller that controls the operation of the telescoping control means, and operating the undulating cylinder to If the tip of the boom exceeds the workable limit line when raising and lowering the boom, the controller controls the operation of the telescopic control means to retract the telescopic cylinder, so that the tip of the boom exceeds the workable limit line. A control device for a boom working machine, characterized in that the boom is raised and lowered along a possible limit line.
