おけるブーム昇降用シリンダ装置の制御操作装置。A breaker in which a boom having a breaker main body at its tip is mounted on a vehicle body movable by a traveling device so as to be rotatable up and down by a cylinder device connected to a fluid pressure source provided on the vehicle body, The vehicle body is provided with a control handle that protrudes rearward, a grip provided on the control handle is rotatable, one end of a connecting wire is connected to the grip, and the intermediate portion of the connecting wire is fixed to the vehicle body. The wire is wrapped around a pulley that is supported by a shaft, and folded back to the grip side, and the other end of the folded back is connected to the grip so that it can rotate endlessly. A control operating device for a cylinder device for raising and lowering a boom in a breaker, which is made by linking the operating rod of a control valve that switches to “lower”.
