<p>A vehicle crane has wheeled sub-vehicle (1) supporting a top-vehicle (2) rotatable around a vertical axle and having a boom (3). A ballasting device (4) receives ballasting weights (6), with machine-readable data carrier storing weight readings, and a transmitting device for radio transmission of respective weight readings. A receptacle (5) for the ballasting device (4) operates with at least one read-device (7,8) to ascertain the ballasting ballast weights (6) reading. An electronic processor determines a total actual ballasting to compare with specified desired ballasting.</p> |
