  • 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: 7739960
    Abstract: A running gear, for example, a single-rail lower-flange running gear for hoisting equipment, includes several wheels running on a rail, at least two of which are arranged one behind the other in the direction of travel of the running gear and adapted to be driven by an electric motor. The driven wheels are joined to at least two shafts, which are oriented coaxially to the axis of rotation of said at least two driven wheels.

  • 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: 6634515
    Abstract: A lifting apparatus includes two parallel longitudinal members interconnected by at least one connecting element. A lifting beam is movable by a drive mechanism along the longitudinal members and supports, directly or indirectly, a handling device. Extending parallel to and supporting the lifting beam is a guide rail, which is received in spaced-apart carriages, for displacement in longitudinal direction in a freely running manner, as the lifting beam is moved by the drive mechanism. The carriages are arranged in a space between the longitudinal members and secured to the connecting element, wherein the longitudinal members and the lifting beam are formed with longitudinal grooves for engagement of sliding blocks so that the connecting element, the drive mechanism and the carrying unit are securable to the longitudinal members in any desired longitudinal position, and the guide rail is securable to the lifting beam in any desired longitudinal position.

  • Patent number: 6622437
    Abstract: A load-moment support for an attachment element to be secured one end of a longitudinal aluminum profile, includes a frame structure which embraces four outer sides at the end of the longitudinal aluminum profile in a without play manner. The frame structure has lower abutment surfaces to rest, respectively, against a first pair of opposite outer sides at a level with an end face of the longitudinal aluminum profile, and two tilting edges arranged, respectively, on a second pair of opposite outer sides and extending flush with the end side of the longitudinal aluminum profile. The attachment element arranged at the end face of the longitudinal aluminum profile abuts without play against the end face of the aluminum profile as well as against the tilting edges and the lower abutment surfaces of the frame structure and is secured at least to the abutment surfaces.

  • Patent number: 6508497
    Abstract: An overhead clamp-type gripping device for gripping a load from above, includes a carrier frame which is movable in a vertical direction and has support elements positioned on both sides of a center plane and extending downwards from the carrier frame for movement relative to one another. The support elements have longitudinal guides which define an upwardly open angle with respect to the center plane. Received in the longitudinal guides of the support elements is a gripper unit which includes gripping elements for laterally contacting a load.

  • Patent number: 6471274
    Abstract: A gripper of a liftable and lowerable load-carrying apparatus for a container, includes a frame placed from above onto a container and having spaced-apart cross beams. Each cross beam defines a longitudinal direction and has at least two gripper elements spaced from one another at a distance which is greater than a dimension of the gripper elements, with each gripper element depending from the cross beam for insertion through a container opening when the frame is placed on the container. The cross beam is made of two sheets which are movable relative to one another in the longitudinal direction, with one of the sheets having one of the gripper elements and the other one of the sheets having the other one of the gripper elements, with the two gripper elements movable in opposite direction to one another in the longitudinal direction of the beam between a ready position and a gripping position.
