  • Patent number: 7997433
    Abstract: 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.

  • Patent number: 7784627
    Abstract: 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.

  • Patent number: 7568855
    Abstract: An arrangement for axial securing of a grooved bolt includes a holding element and a securing element. The grooved bolt passes through the holding element in the axial direction. The securing element, which may be connected to the holding element, engages the groove of the bolt and secures the bolt in a locked position.

  • Patent number: 7503263
    Abstract: 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.

  • Patent number: 6422799
    Abstract: A overhead transport system with load-bearing members, in particular transverse bars for attachment of loads, includes running rails which extend in at least two horizontal planes in spaced-apart, parallel disposition, and at least one crane which travels in an upper one of the planes transversely to the running rails for transfer of the load-bearing members from one running rail to another running rail. In order to provide the overhead transport system in a cost-efficient manner with two production or treatment planes while yet saving time as far as transfer of the load-bearing members is concerned, the transfer of the load-bearing members in a lower one of the planes is realized by at least one self-propelled transfer vehicle which travels transversely to the running rails.
