摘要： The present invention relates to lifting gear, more particularly a crane, such as a rotary tower crane and/or mobile crane, having a supporting structure, a determination device for determining a load state and/or an operating state of the supporting structure, and a control unit for controlling actuators of the lifting gear depending on the determined load state and/or operating state, wherein the actuators are allocated to the supporting structure for the active bracing and/or deformation of the supporting structure in a variable manner during lifting gear operation, and the control unit is configured to temporarily and variably brace and/or deform the supporting structure by means of the actuators depending on the detected load state and/or operating state in order to relieve the load on supporting structure parts which are subject to high load.

摘要： The invention relates to a crane, in particular a rotary tower crane, comprising a crane boom, from which a load hook can be raised and lowered via a hoist cable, and an electric power supply on the load hook and/or an optionally provided trolley which can be moved on the crane boom. According to the invention, the electric power is directly generated at the location where it is required, and in the process kinetic energy present at said location is converted into power. According to the invention, the electric power supply comprises a generator which is arranged on the load hook and/or on the trolley and which can be driven by a deflecting and/or running pulley and/or a cable running around the deflecting pulley.

摘要： A rotary tower crane with a tower, which carries a jib and a counterjib, with a jib stay being guided from a tower top to the jib and to the counterjib. The jib stay tensions only an inner jib portion, the length of which is less than 40% of the total length of the jib, and an outer portion, the length of which is more than 60% of the total length of the jib, forms an untensioned bending beam jib which includes at least one jib piece which tapers in height and which is adjoined on the inner side by at least one jib part of greater height and on the outer side by a jib piece of smaller height.

摘要： 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.

摘要： The invention relates to a construction and/or material-handling machine, in particular a crane, comprising a movable functional element, in particular a functional element suspended in an oscillating manner, in particular in the form of a load receiving means, at least one drive device for moving the functional element, a detection device for detecting manual manipulation movements for moving the functional element, and a controller for actuating the drive device on the basis of the detected manipulation movement. The aforementioned detection device has an inertial measuring device, which is attached to the functional element and comprises an acceleration and rotational rate sensor means for providing acceleration and rotational rate signals, and a detection device for detecting the deflection of the functional element from the aforementioned acceleration and rotational rate signals of the inertial measuring device, and the aforementioned controller is de-signed to actuate the at least one drive device so as to compensate for the detected deflection.

摘要： A control stand is disclosed for controlling a crane, an excavator, a crawler, or a similar construction machine having a seat, control elements actuable from the seat for inputting control commands, a display apparatus for displaying information, and a control unit for generating adjustment signals in dependence on input control commands and/or for providing information to the display apparatus. A crane is disclosed having such a control stand that can be configured in the form of a crane operator's cabin. The control elements and/or the display apparatus of the control stand and various further auxiliary units can be individually configurable. Personal pre-settings can be saved and can be reinvoked when the control stand or the crane is to be controlled by a certain machine operator.
