<p>The crane has crane units moved by an actuator (11), and a crane control unit (5) controlling and/or monitoring movement of the crane units. An operating switch (14) operates the actuator, and is designed as a multi-axial tiltable steering column. A logic component (15) is integrated into the operating switch, and the actuator is directly controlled corresponding to switching movement by the logic component. The control unit is connected with the logic component by a data transmission circuit (16). The operating switch has a bus connection for communication with the control unit.</p> |
