Abstract (en)

Device for moving a load changing as a function of the lifting gear comprises at least one tension device (3), especially a cable, a belt or a chain, for absorbing the lifting forces, and several deviating devices, especially saddles and/or rollers (4, 7). A number of deviating devices are provided for at least partial transfer of the lifting forces from the branches of the tension device to a number of support elements (1, 5) assigned to the deviating devices and suitable especially for introducing the lifting forces into bearings (2). The number of branches impinged upon by the lifting forces changes during the lifting process. An Independent claim is also included for a process comprising the above device. Preferred Features: The load is lifted via a single continuous tension device.
