Patent number: 7997433Abstract: A device for suspending a rail of an overhead conveyor or a hoisting machine from a traversing gear or supporting structure includes a tension element, which carries the rail by one end via a fixing device. The fixing device grasps a support element of the rail. The support element widens and extends at least partly in the lengthwise direction of the rail. To provide a device for suspending a rail that provides enhanced safety against collapse, the fixing device includes two fixing parts, which are connected like pliers by means of a bolt running in the lengthwise direction of the rail. The fixing parts swivel toward each other from the open position into the fixing position by their fixing regions. The support element of the rail rests against the bearing surfaces of the fixing parts, even in the open position, when the fastening means are released.Type: GrantFiled: September 29, 2006Date of Patent: August 16, 2011Assignee: Demag Cranes & Components GmbHInventors: Reinhard Birkigt, Michael Buike, Klaus Enners, Stefan Fitzler, Udo Gersemsky, Ingo Grassmann, Sven Müller, Klaus Nerger, Stefan Steinberg, Rüdiger Ostholt

Patent number: 7503263Abstract: A device for suspending a rail, such as a travel rail of an overhead conveyor or a hoisting machine, from a traversing gear or supporting structure includes a tension element secured by one end to the rail. A bolt passes through the tension element and is received by a fixing device that is secured to the rail. The tension element is at least partly recessed in the fixing device in the direction of suspension. In order to provide a secure device that has a long service life and a low structural height, the tension element is fastened to the bolt by a ball-shaped joint, such as a pivoting bearing.Type: GrantFiled: September 29, 2006Date of Patent: March 17, 2009Assignee: Demag Cranes & Components GmbHInventors: Reinhard Birkigt, Michael Buike, Klaus Enners, Stefan Fitzler, Udo Gersemsky, Ingo Grassmann, Sven Müller, Klaus Nerger, Stefan Steinberg, Rüdiger Ostholt

Patent number: 7504602Abstract: The invention relates to a suspended control device (20) which is suspended by means of a control line (1, 24) connected to a unit to be controlled (21). Said suspended control device is especially a control switch or a suspended push-button switch for controlling hoisting equipment, the control line (1, 24) comprising electrical lines (2) for transmitting control signals, and a traction relief element (22) which is supported at the top, on the unit (21), and used to absorb weight and tractive forces. The aim of the invention is to provide a suspended control device (20) whereby the length of the control line (1, 24) can be easily changed. To this end, a storage element for receiving and releasing a defined length of the electrical lines (2) is provided behind the region wherein the traction relief element (22) is supported, seen in the direction of the unit (21) from the suspended control device (20).Type: GrantFiled: June 30, 2003Date of Patent: March 17, 2009Assignee: Demag Cranes & Components GmbHInventors: Michael Röhr, Udo Gersemsky, Wolfgang Krebs, Anton Münzebrock, Rüdiger Ostholt, Giuliano Persico, Erik Appel, Oliver Ullrich, Burkhard Hasenack, Holger Freitag, Jürgen Heun
