Patent number: 10046953Abstract: The present invention comprises a method for the control of a drive of a crane, in particular of a slewing gear and/or of a luffing mechanism, wherein a desired movement of the boom tip serves as an input value on the basis of which a control parameter for the control of the drive is calculated, characterized in that the oscillation dynamics of the system comprising the drive and the crane structure are taken into account in the calculation of the control parameter to reduce natural oscillations. The present invention furthermore comprises a method for the control of a hoisting gear of a crane, wherein a desired hoisting movement of the load serves as an input value on the basis of which a control parameter for the control of the drive is calculated.Type: GrantFiled: July 8, 2010Date of Patent: August 14, 2018Assignee: LIEBHERR-WERK NENZING GMBHInventors: Klaus Schneider, Oliver Sawodny, Sebastian Kuechler

Patent number: 9790061Abstract: The present disclosure relates to a crane controller for a crane which includes a hoisting gear for lifting a load hanging on a cable, with an active heave compensation which by actuating the hoisting gear at least partly compensates the movement of the cable suspension point and/or of a load deposition point due to the heave, and an operator control which actuates the hoisting gear with reference to specifications of the operator, wherein the division of at least one kinematically constrained quantity of the hoisting gear is adjustable between heave compensation and operator control.Type: GrantFiled: March 7, 2013Date of Patent: October 17, 2017Assignee: Liebherr-Werk Nenzing GmbHInventors: Klaus Schneider, Sebastian Kuechler, Oliver Sawodny, Johannes Karl Eberharter
