A crane or mobile crane includes a crane base, a crane jib to be slewed relative to the base about a slewing axis vertically oriented in normal operating state. A counterweight carrier coupled to the crane jib slews therewith and carries counterweight modules in normal operating state. An anti-collision sensor system monitors the presence of an object within a slewing range ahead being passed through by the counterweight carrier and/or counterweight modules in the future during normal operation as the crane jib slews. A control unit linked to the anti-collision sensor system for signal transmission is configured to determine, based on sensor signals transmitted by the anti-collision sensor system, whether an object is present in the slewing range ahead, to determine whether the object can lead to a collision with the counterweight carrier or one counterweight module, and to take a countermeasure upon a collision.
