A vehicle crane includes a carbody, a turntable rotatably mounted on the carbody, a jib mounted on the turntable that can be tilted about a horizontal axis, and a counterweight assembly mounted on the turntable and can be moved relative to the turntable. A coupler mechanically couples the position of the counterweight assembly to the tilt angle of the jib. The coupler is embodied such that it can be decoupled.
