Abstract: A method for moving a lifting device includes: in a presetting phase, presetting at least one target position for the lifting device; in a measuring phase, detecting an instantaneous geometry of the arm system; in a selection phase, selecting a target position specified in the presetting phase; in a comparison phase, determining a geometrical deviation between the geometry of the target position selected in the selection phase and the instantaneous geometry detected in the measuring phase; in a generation phase, generating at least one control command on the basis of the geometrical deviation determined in the comparison phase; and in a control phase, performing at least partial movement of the lifting device into the selected target position by actuating the actuators of the arm system with the at least one control command generated in the generation phase.

Abstract: A method for indirectly determining an extension length of a telescopic push arm of a telescopic jib relative to a further telescopic push arm or to a main arm of the telescopic jib of a hoist includes a first sensor ascertaining a first parameter of the telescopic push arm and/or telescopic jib. On the basis of the first parameter, a first virtual extension length is determined and/or calculated. The first sensor and/or at least one further sensor ascertains a further parameter of the telescopic push arm and/or telescopic jib. On the basis of the further parameter, a further virtual extension length is determined and/or calculated. The extension length of the telescopic push arm or the telescopic jib is determined and/or calculated by the first virtual extension length and the further virtual extension length.

Abstract: A method for open-loop and/or closed-loop control of a vehicle-mounted lifting gear, which lifting gear comprises an articulated crane arm system having a crane and a crane base, includes taking into account a determined position of at least one point of the crane arm system. A deformation of the crane arm system arising under the action of dynamic and/or static forces is taken into account when determining the position of the at least one point. An oblique position of the lifting gear resulting from an inclination of the crane base relative to a predetermined or predeterminable direction in space is determined and taken into account when determining the position of the at least one point.

Abstract: A crane, in particular a loading crane, includes an arm system that has a plurality of arms. The crane also has a crane controller that is configured, in a coordinate control operating mode, to control the coordinates of the arm system. The crane controller has a user interface, and the user interface has at least one function which can be selected by a user and by way of which at least one of the degrees of freedom of the arm system can be restricted or is restricted in the coordinate control operating mode.

Abstract: A crane controller for a crane, in particular a cargo crane, has a first operating mode, in which the crane can be user-operated by control commands from an operator, and a second operating mode that can be activated by the operator. In the second operating mode, the crane geometry can be changed by the crane controller in a pre-defined sequence of movements. The crane controller has a menu-drive user interface, and the interface has a function which can be selected by the operator and by which the crane controller switches from the first to the second operating mode.
