  • 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: 7504602
    Abstract: 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).

  • 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: 7119295
    Abstract: The invention refers to a hanging control device connected to a unit to be managed, specifically control switches or hanging control panels in order to control hoisting gear, by means of a control line, whereby the control line contains electrical lines (2) to transmit control signals and strain relief, which is supported at the top of the unit to absorb weight and traction forces. In order to create a hanging control device for which the length of the control line can be easily changed, we suggest that strain relief be created by means of hose (6), which can be folded flat and has the design of a type of textile hose, and that electrical lines (2) run through the inside of the hose.

  • Patent number: 6837701
    Abstract: A device for the removal of plastic injection moldings from the mold of an injection molding machine having movable and fixed die chucking plates includes a drive unit for moving an actuating element toward or away from the mold. The actuating element is connected to a spindle mounted in an engagement component. One end of the spindle is connected to a toothed disk. A tubular component is mated with the toothed disk so that the toothed disk is fixed with respect to rotation relative to the tubular disk and is axially movable therein. The tubular component is rotatable by the drive unit for effecting the axial displacement of the actuating element.

  • Patent number: 6523875
    Abstract: Apparatus for grasping a load from above or from the side, in particular for use in a manipulator, includes two parallel elongate beams, and two carriers extending in a direction of the elongate beams, with each of the carriers supported by a corresponding one of the elongate beams and guided for displacement longitudinally in the direction of the elongate beams. The carriers are disposed in spaced-apart relationship, when viewed in a longitudinal direction of the carriers, and are movable relative to one another at least over a portion of a longitudinal extension of the carriers. Two confronting grippers are secured to the ends of the carriers and positioned on the outside of the carriers, when viewed in a direction transversely to the carriers and when the carriers are completely moved apart. A primary fluid-operated system is provided for moving the carriers in opposition to one another.

  • Patent number: 6412846
    Abstract: A gripper, has a frame for movably guiding four radially movable gripper jaws in four shafts which extend radially outwards. An arbor is disposed centrally between longitudinal carriers of the frame in parallel relationship thereto, whereby the arbor, at least over a portion of its length, is conically tapered downwardly and can be shifted longitudinally by a piston-cylinder unit. The gripper jaws are spring biased radial against the arbor, whereby the contact surfaces of the gripper jaws are configured in conformity with the outer arbor surface. Each gripper jaw includes a plate-shaped central element and at least two parallel plate-shaped lateral elements which are laterally disposed to the central element and include a depression directed towards the outer side of the gripper jaw and having a cross-section, which, as viewed in the direction of the lateral surface of the lateral element, may have the shape of an isosceles triangle.

  • Patent number: 6196133
    Abstract: 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.
