  • Publication number: 20140000472
    Abstract: The invention relates to an arrangement comprising a travelling mechanism girder and a running wheel block fastened detachably thereto, wherein the running wheel block is comprised of a housing with at least one connection surface and a running wheel which is mounted in the housing and protrudes out of the housing. To facilitate the exchange of running wheel blocks, alignment of the running wheel block with respect to the travelling mechanism girder is secured through the use of a machined groove, in which a machined plate is held in a form-fitting manner, arranged on the connection surface of the running wheel block. After the running wheel block has been properly aligned, the plate is fixedly connected to the travelling mechanism girder, maintaining the alignment. The invention also relates to a method for the installation of an arrangement consisting of a travelling mechanism girder and a running wheel block.

  • Publication number: 20130282178
    Abstract: A control method for a balancing lifting gear which includes a lifting motor that can be actuated by a controller and uses a control handle with a force sensor to lift and lower a load-supporting device. In a “Balance” operating mode, the load-supporting device, with or without a picked-up load, is raised or lowered by the controller in response to a force applied by an operator. In order to ensure disturbance-free handling of a load when removing or attaching a load, a “Pick-up” operating mode or an “Assemble” operating mode is selected, in which the load-supporting device is moved independently without the influence of the force of the operator by the controller in the lifting or lowering direction in dependence upon the signals determined by the force sensor. A balancing lifting gear which operates in accordance with the aforementioned control method is also disclosed.

  • 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: 7766551
    Abstract: The invention relates to a rotor block (1) comprising a housing (2) with at least one connection surface (3A) that absorbs the load and pivot bearing seats (4) for plain and/or anti-friction bearings (5) that are designed to support a rotor (6). To dismount the rotor (6) from the housing (2), the plain and/or anti-friction bearings (5) can be dismantled from the exterior and the rotor (6) from a side (8) lying transversally to the bearings. The pivot bearing seats (4) take the form of recesses (9) that are directly configured in the housing wall, without the use of annular bodies. To facilitate the mounting and dismounting processes and to improve the precision of the rotor alignment, the pivot bearing seats (4) are configured in such a way that they form a segment greater than a semi-circle around the plain and/or anti-friction bearings (5), leaving a section open on one side (8) in relation to said bearings (5), thus forming a narrowing (13).
