Claim 0:
1. A crane comprising:
at least three actuators which can be activated independently of one another for moving at least one container or another load;
a crane controller comprising:
control electronics;
at least one input device connected to the control electronics and having a grip part, the grip part having a main axis that is pivotable, together with the grip part in at least two pivoting directions oriented orthogonally to one another;
wherein the control electronics are configured to generate electrical signals for activating the at least three actuators of the crane, in dependence on an adjustment of the grip part relative to an original position of the grip part; and
the grip part, with the main axis, is additionally displaceable in at least two mutually different displacement directions relative to the original position, and the control electronics are further configured to generate the electrical signals for activating the at least three actuators of the crane, in dependence on the adjustment of the grip part relative to the original position; and
a crane girder, a trolley that travels on the crane girder, and a load-receiving device connected to the trolley, wherein the actuators of the crane, which are activatable by the input device in a coarse-positioning mode of the crane controller, comprise at least one travel drive configured for moving the crane girder of the crane in mutually opposed crane travel directions, and at least one trolley drive configured for moving the trolley of the crane along the crane girder in mutually opposed trolley movement directions, and at least one hoisting gear drive configured for moving the load-receiving device relative to the trolley in mutually opposed lifting/lowering directions.
