Abstract: A crane controller for controlling travel movements of a crane, in particular a portal crane. The crane controller includes control electronics and at least one input device, connected to the control electronics, having a grip part, a main axis of the grip part is swivellable together with the grip part in at least two swivel directions oriented, in particular orthogonally, in relation to one another, and the control electronics are able to generate electrical signals, for actuating at least one actuator of the crane, on the basis of an adjustment of the grip part relative to an original position of the grip part. The grip part has its main axis additionally displaceable in at least two, preferably three, different displacement directions relative to the original position and/or is rotatable about the main axis, and the control electronics generate electrical signals for actuating the at least one actuator of the crane.

Abstract: A rail carriage group (1) for a crane (3), in particular a gantry crane, which is moveable on rails (2) with a rectilinear rail profile and around at least one curve and in a transition between the rectilinear rail profile and the curve, with at least two, in particular at least four, running wheels (4), the running wheels (4) supporting subframes (5) of the rail carriage group (1), and the subframes (5) supporting a superstructure (6) of the rail carriage group (1), wherein at least one of the running wheels (4), preferably each running wheel (4), is rotatable individually about a running-wheel axis of rotation (7) which is vertical in the operating position.
