The present invention relates to a crane, in particular to a revolving tower crane, having a load suspension means attached to a hoist rope, drive devices for moving a plurality of crane elements and for traveling the load suspension means, a control apparatus for controlling the drive devices such that the load suspension means travels along a travel path, and an oscillation damping device for damping oscillation movements of the load suspension means, wherein said oscillation damping device has a control module for influencing the control of the drive devices in dependence on oscillation-relevant criteria. It is proposed not only to take account of the actual oscillation movement of the rope per se in the oscillation damping measures, but also the dynamics of the steel construction of the crane and its drivetrains.

Crane, and method for controlling such a crane

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.

Crane

The present invention generally relates to the control of material transfer machines and/or construction machines having camera assistance. The invention here in particular relates to a method and to an apparatus for controlling a material transfer machine and/or a construction machine, in particular in the form of a crane, of an excavator, or of a crawler-type vehicle, wherein an image of the piece of working equipment is provided to a machine operator and/or to a machine control by an imaging sensor. The invention furthermore also relates to the material transfer machine and/or construction machine itself, in particular to a crane, having a display apparatus for displaying an image of the piece of working equipment and/or of the environment of the piece of working equipment. It is proposed to use a remote-controlled aerial drone which is equipped with at least one imaging sensor and by means of which the desired image of the piece of working equipment and/or of the equipment environment can be provided from different directions of view.

Method and apparatus for controlling a crane, an excavator, a crawler-type vehicle or a similar construction machine

A crane, a construction machine or an industrial truck, with a control station including at least one input means for inputting control commands, a graphical simulation module for calculating a virtual representation of the machine surroundings and/or machine components visible from the control station, such as a boom or a load hook, and a display device for displaying the calculated virtual representation, wherein a movement simulation module is provided for determining movements and/or deformations of the machine components according to the inputted control commands, depending on which the graphical simulation module calculates the virtual representation. Proposed is a data emulation using hardware components, which carry out actual actuating movements and thus simulate 'actual' actuating movements of the machine to be simulated, in order to provide corresponding movement data more rapidly and with less computing performance, whereby a more realistic simulation can be achieved in real-time or almost real-time.

Crane, construction machine or industrial truck simulator

A simulator for a crane, a construction machine or an industrial truck, with a control station including at least one input means for inputting control commands, a graphical simulation module for calculating a virtual representation of the machine surroundings and/or machine components, such as a boom or a load hook, and a display device for displaying the calculated virtual representation, a movement simulation module being provided for determining movements and/or deformations of the machine components according to the inputted control commands, according to which the graphical simulation module calculates the virtual representation. The control station is movably mounted and can be moved by a drive device according to the movements and/or deformation of the machine components determined by the movement simulation module. The virtual representation generated by the graphical simulation module can be superimposed with a live image provided by a camera and displayed on virtual reality glasses.

Simulator for crane, construction machine or industrial truck

The present invention relates to 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.

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.
