20120091410 | WINDING DRUM AND METHOD FOR OPERATING A WINDING DRUM - In a method of operating a winding drum, in particular of cranes, for a line to be reeled in or paid out, a hydraulic motor is activated by a control block which has a hydraulic valve assembly comprised of two pressure control valves respectively arranged in a feed line and a return flow line, for operating the winding drum. The pressure control valves are provided to set a pressure differential on the hydraulic motor in order to maintain a defined tautness of the line being reeled in or paid out. | 04-19-2012 |
20120031721 | LAND CONNECTION FOR MARINE VESSELS HAVING AN ARTICULATED CRANE - An apparatus for electrically connecting a polyphase vessel distribution system of a vessel to a polyphase land supply system having a supply system connection disposed on land to be connected to a vessel system connection of the vessel distribution system at least in sections by at least one cable connection, enables a fast and secure connection of the land supply system to the vessel distribution system. During normal operation, vessel movements can be reliably compensated by at least one articulated arm used as a support for one or more cable connections. The articulated arm has arm segments interconnected by at least one articulated connection. A joint drive is associated with each articulated connection for mutually pivoting the arm segments interconnected by the articulated connection, which is associated with the joint drive. | 02-09-2012 |
