A crane vehicle achieves safe movement by reliably detecting an obstacle in a region which is a blind spot from the opposite side of the driver seat across a boom. The crane vehicle includes an obstacle sensor which is a transmission/reception antenna that transmits a detection wave and receives the detection wave reflected from the obstacle. A signal corresponding to the reflected wave received by the obstacle sensor is amplified and input to a controller, which calculates the position and the size of the obstacle on the basis of the signal. The controller generates an obstacle display image and displays the image on a display, the obstacle display image including a vehicle object that represents a crane vehicle and an obstacle object which is an object corresponding to the calculated size of the obstacle and which is disposed at a position corresponding to the calculated position of the obstacle.
