Definitions

  • ABSTRACT 11 Claims 1 Drawing Figure LOA-D TAKE-UP APPARATUS FOR LIFTING DEVICES
  • the invention relates to a load take-up apparatus for lifting devices, more particularly spreaders for container lifting devices with retainingmeans which bear upon and grip the load, more particularly rotating bolts which are disposed at the corners of the spreader and are lockable in fittings of the container.
  • the invention relates in first place to problems which arise when containers are loaded by means of container bridges and the like.
  • the lifting device of such container bridges is provided with a spreader suspended from the hoisting ropes and intended for taking up the container. If a container is to be taken up from a storage area, forexample the quayside or the storage deck of a ship the spreader is placed from above on the container.
  • the retaining means namely rotating bolts, which are disposed at the corners of the spreader, enter into fittings on the corners of the container and are locked therein by rotation.
  • the load take-up device is characterized in that the re taining means for taking up the loads, more particularly the rotating bolts, are resiliently supported on the load take-up device, more particularly on the spreader.
  • the retaining device or rotating bolt respectively is preferably supported on a spring with strong natural damping, for example on a resilient buffer block-of plastics material with a large work-absorption capacity.
  • the drawing represents a vertical section through retaining means, namely a rotating bolt according to the invention on a spreader.
  • the load take-up device more particularly a spreader may be constructed in suitable manner.
  • the drawing shows only the outer lower corner which is provided with retaining means, namely a rotating bolt 11, fortaking up the load, in this case a container.
  • retaining means namely a rotating bolt 11, fortaking up the load, in this case a container.
  • the lower zone of the rotating bolt 11 is constructed in such a way that it is able to enter into a fitting disposed on the top of the container and may be locked in the said fitting by being rotated.
  • the rotating bolt 11 which bears on the container when the spreader I0 is lowered thereon, is resiliently supported.
  • the rotating bolt 11 is rotatably guided in a bearing member 12 which in turn is part of a carrier 13.
  • the buffer block 15 is disposed in a housing 16 surrounding the said block, the carrier 13 being guided and supported therein so as to be vertically slidable.
  • the carrier 13 is located in the housing 16 so that the buffer block 15 is under prestress when the rotating bolt 11 is unstressed in such a way that only increased loadings on the rotating bolt 11 result in a damped resilient motion of the carrier 13 accompanied by compression of the buffer block 15.
  • the housing is rigidly coupled to the spreader 10.
  • the carrier 13 is supported in the housing 16 so as to merely permit axial motion but no rotating motions.
  • a lower zone 17 ofthe carrier 13 is constructed to have a polygonal circumferential surface. This bears positively on a surface of a zone 18 on the inside of the casing 16, said surface being also of corresponding polygonal construction.
  • the carrier 13 is provided not only for accommodating'the rotating bolt but also for accommodating any actuating and monitoring elements such as electric and hydraulic drives, switching apparatus and safety circuits.
  • this includes a tracer pin 19 the function of which is to monitor the operation of locking of the locking bolt in the fitting of the container.
  • the tracer pin 19 is adjoined by a flexible conduit 20 which transmits the signals ofthe tracer pin 19 to a limit switch or the like.
  • the deformability of the conduit 20 permits axial motions of the rotating bolt 11 or of the carrier 13 respectively without damage to the conduits and connections.
  • An actuating arm 21 by means of which the rotating motions for locking the rotating bolt 11 are transmitted thereto is attached to the same end by means of a separate bearing 22 to the upper end of the rotating bolt 11.
  • the said bearing 22, by means of which primary pivoting motions of the actuating arm 21 are to be transmitted to the rotating bolt 11 in one plane as rotating motions, is constructed with spherical bearing surfaces 23 which are adapted to compensate for axial motions of the rotating pin 11.
  • the buffer for absorbing the increased impact load ings may also be constructed as a mechanical spring with a shock damper, for example a hydraulic shock damper.
  • a shock absorbing load take-up apparatus for containers having a supporting frame and rotatable bolts disposed thereon and adapted to be inserted into corresponding fittings in the container, the improved rotatable bolt mounting comprising:
  • said resilient buffer means comprises a cellular plastic material, such as polyurethane, having a high work absorption capacity.
