Patent number: 9091026Abstract: An arrangement of a suspension and of a rail is provided, in particular for suspending a travel and/or carrier rail or a lifting gear on a chassis or frame, having a tension element supporting the rail at one end thereof in the region of a profile head by a mounting element, with the head being substantially C-shaped in cross section, and forming a gap running at the top along a longitudinal center plane of the rail. The mounting element comprises a pivotable part that can be pivoted with respect to the tension element, the profile head and the pivotable part being designed such that the pivotable part can be guided through the gap from outside into the profile head in a loading position, and can be pivoted into a mounting position in which the pivotable part contacts the profile head from the inside, bridging the gap.Type: GrantFiled: September 5, 2011Date of Patent: July 28, 2015Assignee: Terex MHPS GmbHInventors: Gerd Spies, Stefan Fitzler, Sven Müller

Patent number: 9067765Abstract: A rail for suspended conveyors and suspended cranes, having a substantially C-shaped profile head for suspending the rail and a profile body connected thereto. The profile head is open at the top, thereby forming a gap running along a longitudinal center plane bounded on both sides by first web segments extending outward from the center plane. Two second web segments opposite each other and running downward and outward as seen in cross section are connected to the first web segments and the rail is made of two profiles disposed symmetrically about the vertical longitudinal center plane as seen in cross section. The rail supports an overload protection in the region of the profile head, and allows simple attachment by suspension supports. In a particular embodiment the first web segments run diagonally outward and upward and the first web segments are angled relative to the longitudinal center plane.Type: GrantFiled: September 5, 2011Date of Patent: June 30, 2015Assignee: Terex MHPS GmbHInventors: Gerd Spies, Stefan Fitzler

Publication number: 20120061527Abstract: The invention relates to trailing cable assembly including a hollow-profile rail that is open over a longitudinal gap and a plurality of suspension elements, which can be moved along the rail and to which an electrical power line may be fastened. In order to create such an assembly in which the suspension elements can be easily mounted and replaced, the suspension elements include support parts that can be introduced into a hollow space of the rail from the outside by way of the longitudinal gap to be in a mounting position, and the support part can be moved out of the mounting position and into a operating position in which it bridges the longitudinal gap of the rail.Type: ApplicationFiled: April 27, 2010Publication date: March 15, 2012Applicant: DEMAG CRANES & COMPONENTS GMBHInventors: Gerd Spies, Stefan Fitzler, Sven Muller

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: 7784627Abstract: A device for suspending a rail, particularly a running rail of an overhead conveyor or of a lifting apparatus, on a traveling mechanism or supporting framework with a traction element, which is fastened at one end to the rail. The traction element is passed through by a bolt, which is fastened to the rail via a fixing device. The traction element consists of a single part and comprises a lower borehole for the bolt and an upper borehole for fastening to the traveling mechanism or to the supporting framework.Type: GrantFiled: August 4, 2006Date of Patent: August 31, 2010Assignee: 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: 6196133Abstract: A device for the suspension of a rail, especially of a hollow-section rail which opens downward in a suspension crane, includes a carrying apparatus with a traction element which has two ends. One of the ends of the traction element may be fasten to the rail. To provide a rigid suspension of a rail in which horizontal forces, especially pulse-like horizontal forces, are extensively damped, the device includes a rubber-metal element connected between the carrying apparatus and the traction element with two substantially horizontal metal carriers arranged at a distance from one another. A rubber or elastic element is fastened to the inner surfaces of the metal carriers, which inner surfaces face one another. The carrying apparatus is fixedly connected with the lower metal carrier and the other end of the traction element is fixedly connected with the upper metal carrier.Type: GrantFiled: November 19, 1998Date of Patent: March 6, 2001Assignee: Mannesmann AGInventors: Stefan Fitzler, Rüdiger Ostholt
