Patent number: 10723595Abstract: A method and assembly for operating at least two lifting gears in a group operation, where each lifting gear has a hoist via which a respective cable or chain can be raised or lowered. The hoists are first operated in a synchronous operating mode to perform a common lifting procedure to move a load supported by the hoists. At least one of the hoists involved in the common lifting procedure is then deactivated to switch from the synchronous operation into an individual operation or a multi-operation, with at least one of the hoists remaining activated to carry out a lifting or lowering process relative to each deactivated hoist. A load value is then determined for the at least one deactivated hoist and compared to a predetermined threshold value of the at least one deactivated hoist.Type: GrantFiled: October 21, 2016Date of Patent: July 28, 2020Assignee: Konecranes Global CorporationInventor: Klaus Behnke

Publication number: 20180319633Abstract: A method and assembly for operating at least two lifting means in a group operation, wherein each lifting means has a hoist via which a respective load-receiving means can be raised or lowered, in which group operation, in a synchronous operating type, first a common lifting process is carried out via the hoists in order to move a load, after which, for shifting from the synchronous operation into an individual operation or a multi-operation, at least one of the hoists involved in the common lifting process is deactivated, and at least one of the involved hoists remains activated, such that only each activated hoist can carry out a lifting process or lowering process relative to each deactivated hoist. After the shift from the synchronous operation to the individual operation or the multi-operation, a load value is determined for each hoist previously involved in the common lifting process of the synchronous operation.Type: ApplicationFiled: October 21, 2016Publication date: November 8, 2018Inventor: Klaus Behnke

Patent number: 9272883Abstract: A method and control assembly are provided for operating at least two lifting devices, such as cranes, in group and normal operation modes. Each lifting device has a control system connected to a control switch, and the lifting devices are controlled through a common bus. In group operation, the lifting devices are jointly controlled through the bus by one switch. To operate at least two lifting devices in parallel, one of the switches is active in the group operation and the remaining switch or switches are passive. To prepare for group operation, normal operation is deselected by all but one of the control switches to release a remaining switch for log-in to the active state for group operation. To prepare for normal operation, group operation is deselected and normal operation is selected at the active switch before the other switch or switches are released for logging into normal operation.Type: GrantFiled: August 23, 2012Date of Patent: March 1, 2016Assignee: Terex MHPS GmbHInventor: Klaus Behnke

Patent number: 6311475Abstract: A device for igniting a combustion in a combustion chamber of a gas turbine has a housing fitted with an end piece and with a head piece. Hitherto, an ignition conductor comes into contact with combustion air. Moreover, fragments of a partial ceramic insulation can lead to damage. To improve the quality of ignition, the ignition conductor and a gas conduit are disposed to run parallel to one another within a housing. The ignition conductor is surrounded by a protective sleeve, and an annular space between the ignition conductor and the protective sleeve is filled completely with a ceramic material. An annular disc serving as an ignition electrode is mounted on that end of the protective sleeve that projects into the head piece.Type: GrantFiled: May 31, 2000Date of Patent: November 6, 2001Assignee: ABB Patent GmbHInventors: Ung-Lap Ngo-Beelman, Mark Renner, Jens Schlundt, Gerolf Heintz, Mario Leonhard, Ludwig Wahlig, Klaus Behnke, Michael Witt, Christian Bohtz, Jens Molsen, Reinhold Schmidt

Patent number: 6233939Abstract: In a steam power station, the condensate used as feedwater is preheated up close to the boiling temperature by means of partial steam mass flows from the turbine steam quantity. Due to the steam extraction, the following steam-turbine stages can draw less power from the steam fluid. To avoid the reduction in the power output at the following steam-turbine stages, provision is made for the waste heat from fuel cells to be used for preheating the condensate. Due to the preheating of the feedwater from the waste heat of the fuel cells and the associated increase in the steam quantity participating in the expansion, an increase in the efficiency of the steam process is achieved.Type: GrantFiled: May 30, 2000Date of Patent: May 22, 2001Assignee: ABB Patent GmbHInventors: Ung-Lap Ngo-Beelmann, Klaus Behnke, Michael Witt

Patent number: 4698565Abstract: The hoist, lifting apparatus or the like of our invention comprises at least one hoist motor, a protective controller for the hoist motor, and an overload safety device operating on the protective controller, wherein the overload safety device has a cable load force pick-up with a tension measuring bridge, an analyzer, and a mechanism for suppression of load peaks in periodic load fluctuations. The tension measuring bridge is connected with two connecting conductors to a bridge supply generator and has two output conductors for transmission of the output signal of the tension measuring bridge. The analyzer acts on the protective controller for the hoist motor. Between the analyzer and the tension measuring bridge is a frequency converter with associated frequency generator which changes the output signal of the measuring bridge into a periodic signal.Type: GrantFiled: July 18, 1985Date of Patent: October 6, 1987Assignee: Mannesmann AktiengesellschaftInventors: Klaus Behnke, Anton Munzenbrock
