Abstract: The present invention relates to a remote control device for a crane, for a construction machine and/or for a pallet truck comprising a control station that has at least one input means for inputting control commands and that has a signal transmission device for transmitting the input control commands to the control apparatus of the crane, of the construction machine, or of the pallet truck; and a display apparatus for displaying a representation of the machine surroundings and/or of a piece of working equipment such as a boom or a lifting hook, wherein a movement determination unit is provided for determining movements and/or deformations of the machine components in dependence on the input control commands. It is proposed to present crane reactions or machine reactions to control commands input at the control station, for example in the form of crane movements and/or of crane deformations not only in the form of a representation on the display apparatus, but to convert them into an actual movement of the control station of the remote control accompanying the crane reaction or machine reaction to allow the remote control user to have the dynamic machine reactions communicated to him more realistically and to experience them more realistically.

Abstract: A drive system may have at least one electric motor which can be fed via power electronics which can be connected via a DC circuit to a voltage source and an energy storage apparatus for buffering energy fed back from the electric motor. An energy storage apparatus for such a drive system may include at least one electrical storage block, a bidirectional DC/DC converter for connecting the named DC voltage circuit to the internal voltage circuit of the storage block and a control unit for controlling the DC/DC converter. The control unit may include output and feed control means for controlling the DC/DC converter. The DC/DC converter, the storage block and the control unit may be combined into an energy storage unit having a common housing in which the named components are received and at whose outer side two connections are provided for connecting to the DC voltage circuit.

Abstract: Adjustment and/or drive units that can be used in wind turbines to set the azimuth angle of the wind turbine nacelle or the pitch angle of the rotor blades, wherein such an adjustment and/or drive unit has at least two actuating drives for rotating two assemblies, which are mounted for rotation relative to each other, and has a control device for controlling the actuating drives, which control device controls the actuating drives in such a way that the actuating drives are braced in relation to each other during the rotation of the two assemblies and/or at a standstill of the assemblies. The invention further relates to a wind turbine having such an adjustment and/or drive unit and to a method for controlling such an adjustment and/or drive unit.

Abstract: A tower crane with a load lifting means mounted on a hoisting cable, driving devices for moving several crane elements and traversing the load lifting means, and a control device for controlling the driving devices such that the load lifting means moves along a traversing path between at least two target points. The control device has a traversing path determining module for determining a desired traversing path between the at least two target points and an automatic traversing control module for automatically traversing the load lifting means along the determined traversing path.

Abstract: The present invention relates to a crane, having a jib rotatable about an upright axis, at which jib a trolley is movably arranged, from which trolley a hoist rope connected to a load hook runs off, as well as a load hook position determining device for determining the position of the load hook. The load hook position may be determined optically by means of one camera only, which camera is mounted on the trolley of the crane and views from the trolley in a predetermined and thus known viewing direction downwards onto the load hook. In doing so, the position of the load hook in the camera image is determined by an image evaluator. To simplify detection of the load hook in the camera image, the image evaluator may include rope run determining means for determining the rope run of the hoist rope running off from the trolley.
