Embodiment Construction

[0026] figure 1The lifting device 1 is shown exemplarily by means of a schematic container crane 2, which is used, for example, for loading or unloading ships in a port. Typically, the container crane 2 has a support structure 3 which is either fixed or movably arranged on the ground. In the case of a movable arrangement, the support structure 3 can, for example, be arranged to be able to run on a rail in the Y direction, for example at figure 1 as shown schematically. With this degree of freedom in the Y direction, the container crane 2 can be used flexibly in terms of location. The support structure 3 has a boom 4 which is fixedly connected to the support structure 3 . A support element 5 is generally arranged on the boom 4, which is movable in the longitudinal direction of the boom 4, i.e. in the X direction in the example shown, for example the support element 5 can be supported in guides by means of wheels. The support element 5 is usually connected by means of a re...

Abstract

The invention relates to a method for damping rotational oscillations of a load-handling element 7 of a lifting device 1, wherein at least one controller parameter is determined by a rotational oscillation model of the load-handling element 7 as a function of the lifting height (lH) and wherein, to damp the rotational oscillation of the load-handling element 7 at any lifting height (lH), the at least one controller parameter is adapted to the lifting height (lH).

Description

technical field [0001] The invention relates to a method for damping rotational vibrations about a vertical axis of a load-receiving element of a lifting device with at least one adjustment variable by means of a damping adjuster, wherein the load-receiving element is connected to a lifting element by means of at least three holding elements. The supporting elements of the device are connected, and the length of at least one holding element between the load-receiving element and the supporting element is adjusted by means of an actuator acting on the at least one holding element via a damping adjuster. Background technique [0002] Lifting devices, especially cranes, exist in many different embodiments and are used in many different fields of application. For example, there are tower cranes, which are used in particular for above-ground and underground construction, or there are mobile cranes, for example for the assembly of wind turbines. Gantry cranes are used, for exampl...
