Patent number: 9038990Abstract: A cable winch device, particularly a cable winch device for a crane, has at least one cable winch with at least one cable, with the cable wound and/or unwound at least partially on the cable winch. The cable winch can be shifted and/or moved at least partially substantially along the longitudinal axis of the cable winch. A crane, particularly a deep sea crane, has at least one such cable winch device.Type: GrantFiled: September 11, 2012Date of Patent: May 26, 2015Assignee: Liebherr-Werk Nenzing Ges.m.b.HInventors: Reinhard Krappinger, Eugen Schobesberger, Alexander Koehler

Patent number: 7490728Abstract: A crane, in particular to an offshore crane, having a hoist rope winch, a hydraulic hoist winch drive and an overload protection which is connected to the hoist winch drive and which, when a predetermined permitted limit load is reached, permits a drawing off of the hoist rope from the hoist rope winch under a predetermined variable restoring force dependent on the radius and/or the permitted working load of the crane. A decoupling of the hoist winch drive and thus a mechanical separation of the powertrain between the hoist rope winch and the hoist winch drive is therefore dispensed with and instead the retention force varying in dependence on the radius and/or the respectively permitted working load of the crane is provided by the hoist rope winch drive motor.Type: GrantFiled: July 14, 2006Date of Patent: February 17, 2009Assignee: Liebherr-Werk Nenzing GmbHInventor: Eugen Schobesberger
