A cylinder is provided, and a rotation angle detection means for detecting the rotation angle of the reversing device main body is provided, and the rotation angle detection means applies back pressure to the rotation operation hydraulic cylinder to prevent rapid rotation of the reversing 1flf main body. Therefore, when the reversing device main body holding the object to be reversed exceeds one change point of the load during rotation, the rotation angle detection means detects this and stops this rotation. Based on the detection by the angle detection means, the rapid rotation prevention means applies back pressure to the rotation operating hydraulic cylinder to prevent the rapid rotation of the reversing device body while allowing it to rotate slowly, thereby holding it in the reversing device body. This ends by preventing damage to the object to be reversed.
