Definitions

  • the invention relates to a hanger for continuously adjusting the length of a lifting strap intended to carry a load.
  • Such slings are usually flat-woven textile sling, which can be equipped with loops for attachment to the hook of a transport crane.
  • Hoops with loops but also in endless form are well known from the old DIN 61360 or from the new DIN EN 1492-1. They serve as a stop means with a precisely defined working length.
  • lifting straps with suitable fittings, such as D-bars, they form hangers that can be hooked into a crane hook. Additional forged coupling elements and hooks may be part of the known hangers.
  • the known devices are each available only in a fixed length specified by the manufacturer or user.
  • An adaptation of the length of the lifting straps to the respective transport task to be handled is possible in practice in a meaningful way only by the use of a high-strength stop chain, the length of which is adjustable with Kettenverkürzern. This makes the handling of known devices cumbersome and limits their scope.
  • a hanger known that includes an adjustment and a lifting strap.
  • a loop is formed from an end portion of the lifting belt, which is placed around an axis fixedly connected to a bracket of the adjusting device.
  • the end portion is further guided about a pivot axis and an additional axis which is supported by a pivotable about the pivot axis bracket member.
  • the additional axis of the bracket element only serves to hold the end portion at a distance from the pivot axis when tensioning the known suspension.
  • the section of the lifting belt which leads to a further hook which is offset by the adjusting device is likewise guided over the pivot axis.
  • the relevant, leading to the hook portion of the lifting belt lies on the end portion. Under load, this portion leading to the hook can consequently press so hard against the end portion of the lifting band below it and on the pivot axis that self-locking occurs.
  • the leading to the hook portion of the lifting belt is wound from the pivot axis by more than 180 ° about a likewise carried by the bracket element axis. From there he runs directly to the hook.
  • the lifting strap can be threaded only cumbersome in the adjustment.
  • the stirrup element and the stirrup of the adjusting device are fixedly aligned with each other, so that the position of a hook fastened to the stirrup of the adjusting device can not be adapted to the position or shape of the respective load.
  • the object of the invention is to improve the versatility of devices of the type described above.
  • the pivot axis, the middle part, the middle web and the end web extend substantially axially parallel to one another.
  • a device provided in a hanger designed in accordance with the invention is intended to be attached to the loopless end of a lifting band.
  • the device on the one hand on a U-shaped bracket on which the load to be supported is attached.
  • the device according to the invention is equipped with a stirrup element, via which the coupling takes place with the lifting strap.
  • this bracket member is designed such that the connection between the lifting strap and the device made in a simple manner and required length of the lifting belt can also be easily varied.
  • the device according to the invention can be pivoted in the load-free state into a threading position in which the lifting strap can be laid without the action of the threading forces obstructing the webs of the bracket element and the pivot axis in a suitable manner. Subsequently, the device is pivoted into its load receiving position, in which an adjustment of the tape length is prevented by self-locking in the device.
  • the device according to the invention thus represents a connecting element which, in the sense of a modular system, enables the coupling of various types and forms of loads to a single lifting strap. It not only allows the invention to vary the length of the lifting belt arbitrarily, but it can also be attached to the U-shaped bracket, the most diverse fasteners and hooks are each optimally adapted to the transport task to be handled.
  • each individual strand of such a hanger is coupled via a device according to the invention with the load, the length of each strand can be easily adapted to the geometry and the center of gravity of the load, so that even with a non-uniform geometry loads optimally secure transport can be guaranteed ,
  • the shape of the U-shaped bracket can be simplified in that the necessary for the attachment of the load-receiving element elements are formed on the central part of the U-shaped bracket. Of course, however, it is also conceivable to form corresponding elements on the legs of the respective bracket. With regard to an optimal introduction of the forces to be absorbed during transport in the bracket and the coupled to the strap lifting strap, it is also advantageous if the load-receiving element is pivotally mounted on the U-shaped bracket.
  • a threading the lifting strap substantially facilitating embodiment of the device according to the invention is characterized in that the end web carrying the first side legs is longer than the second side legs of the bracket member. In this way there is a free distance between the end of the end web and the free end of the second side leg. through which the lifting strap can be pushed.
  • the end bar has at its free end oriented in the direction of the end of the second leg bend. This bend sure prevents the band from sliding out of the stirrup element in the unloaded condition or during adjustment of the length.
  • the same purpose is used when the second side leg protrudes with its end end associated with the end of the point where it is connected to the central web. The protruding beyond the Endsteg section prevents slipping of the tape from the center bar.
  • the components of a device according to the invention can be produced by forging.
  • the device 1 is intended for adjusting the length of a lifting belt H and for coupling a load F to the lifting belt H. It has a forged from a metal material U-shaped bracket 2, which has a web-shaped central part 3. At each end of the middle part 3, a leg 4, which protrudes at right angles from it, is formed in each case.
