Provided is a construction machine characterized by comprising: a traveling body (10); a rotating body (20) rotatably provided on the traveling body (10); motors (25, 27) for rotation, the motors (25, 27) rotating and driving the rotating body; a boom (31) connected to the rotating body (20); a boom cylinder (32) for raising and lowering the boom (31); a rotation operation device (72) for instructing the rotational movement of the rotating body (20); a boom operation device (78) for instructing the rising and lowering movement of the boom (31); a detector (74d) for detecting the bottom pressure of the boom cylinder (32); and a controller (80) which, while signals for rotation operation and boom raising operation are being inputted, reduces the rotational speed of the rotating body (20) in response to a signal from the detector (74d), relative to a reference rotational speed corresponding to the signal of rotation operation. As a result of this configuration, a load acting on the boom can be felt on the basis of operation of a front working machine, and the front working machine can be operated without being affected by the load on the boom along a path corresponding to operation. |
