Abstract:
The present invention relates to a crane, preferably a truck crane, comprising a plurality of crane elements which are movable by actuators, a crane control unit for controlling and/or monitoring the movement of the crane elements, and at least one actuating switch for actuating the actuators. In accordance with the invention, the crane is characterized in that in the at least one actuating switch a logic module is integrated, by which the actuators can be driven directly corresponding to a respective switch movement, and the crane control unit can be connected with the logic module by a data transmission connection.
