Definitions

  • the invention relates to apparatus and the use of said apparatus in the lifting of freight devices for transfer or storage.
  • a method used for the lifting of heavy objects, particularly for freight, is to secure and lift using heavy duty wire rope directly to a crane attachment such as a hook.
  • This method permits quick engagement and disengagement of the load and is of low complexity. Whilst most environments are suitable for rapid engagement and disengagement of a load, this is particularly useful for ship borne loads and further, when the ship is subject to vagaries of wind and wave action. In particular, for rough conditions, more conventional methods of engagement are difficult or impossible and, therefore, there is an attraction for wire rope engagement.
  • freight devices such as lifting frames, liftable brackets for binding materials
  • intermodal devices such as flat racks and various types of shipping containers.
  • the items in question are loaded into/onto the freight devices, which are manipulated using purpose-built equipment, for instance, spreaders adapted for use with cranes and the like.
  • the crane is attached to a spreader which engages with twist locks in the corners of, for instance, a conventional container.
  • a spreader which engages with twist locks in the corners of, for instance, a conventional container.
  • twist locks In order for the container to be engaged by the spreader, each of the four twist locks must be individually engaged and, therefore, there is considerable skill required in aligning the spreader with the container in order for engagement.
  • the crane and the container share a common stable base making 5 alignment relatively easy. Even in the case of a ship at berth, the ship may be relatively stable, given the protection of the dock.
  • the present invention provides a lifting apparatus for suspending from a 0 crane in order to lift a freight device comprising:
  • a crane attachment assembly for attaching the first portion of the body to the crane
  • the invention involves combining a multi-use arrangement with a system of rapid engagement/disengagement by incorporating, firstly, a single engagement rather than the four engagement portions of the prior art and, secondly, that this engagement is more easily achieved.
  • alignment is on the basis of a sleeve having an orifice diameter similar to that of the base of the cone.
  • it is merely the tip of the cone that needs to be located within the sleeve orifice in order to ensure alignment.
  • the margin for error available for the engagement of the present invention is considerable when compared to the alignment of, for instance, a twist lock whereby the male portion of the engagement is similar in size to that of the female portion and thus, leaving very little margin for error.
  • the cone may be attached directly to the freight device.
  • the cone may be indirectly attached to the freight device through an intermediate device,
  • the intermediate device may be a frame, for instance, an adapter frame having the cone attached to it at a convenient location, which is engaged with the freight device.
  • the freight device may then be manipulated either through corresponding twist lock engagements in the adapter frame, which may be more convenient within a container yard.
  • the lifting apparatus of the present invention can be used to move the freight device.
  • the adapter frame will not merely permit manipulation by a lifting device of the present invention, but may also permit manipulation by conventional systems.
  • the adapter frame may be a fabricated steel frame having twist lock arrangements in the corners for engagement with a freight device, and having a reinforced portion located centrally for attachment to the cone. Attachment of the cone to the reinforced portion of the adapter frame may be through high tensile bolts or through welding or other means consistent with the load bearing requirements of the cone.
  • the adapter frame may be rectangular for compatibility with existing freight devices.
  • the adapter frame may be purpose-built for use with specific forms of freight. It follows, therefore, that the frame may be any shape, including round for use with circular freight, for instance, foundry vessels.
  • the reinforced portion of the adapter frame may have a recess or cavity beneath the cone such that a plurality of adapter frames may be stacked with the attached cones fitting into the recess of an upper adapter frame.
  • the freight device may also have a recess in an under portion to accommodate a cone.
  • the assembly of the adapter frame, cone and freight device may also be stackable with the cone of one assembly fitting into the recess of an upper assembly.
  • the use of the cone for the manipulation of the freight device with the adapter frame does not limit the use of the present invention, hi fact, it may be applicable to specific types of freight devices, including intermodal devices, for instance, suitably modified containers or flat racks.
  • the present invention may further have a rotational control assembly used to control the twisting and rotation of the apparatus whilst attached to a crane.
  • said control assembly may include the arrangement of connection to the crane.
  • One alternative includes the use of mechanical and motorized rotation devices, which my connect directly or indirectly to the lifting apparatus. Such devices may be operated to rotate the lifting apparatus as required, using powered rotation.

  • the rotational control assembly may include arms projecting laterally from the body of the lifting apparatus to which are attached cables.
  • the attachment of the cables to the projecting arms may be such that an application of a load to the cable will tend to rotate the lifting apparatus.
  • the arms maybe projecting in opposed directions to each other such that rotation of the lifting apparatus in either direction may be achieved by the application of load to either of the attached cables.
  • the arms may be selectively extendable so as to be telescopic. This has the advantage of increasing the applied torque to the lifting apparatus for the equivalent application of force to the cables.
  • the arms prior to engagement with the freight device, it may be beneficial to have the arms unextended so that the applied torque is small and thus, having greater fine control over the rotation of the apparatus.
  • it may be necessary to extend the arms so as to amplify the applied torque in order to achieve an acceptable level of torque, and so an acceptable level of control.
  • the rotational control may be achieved through static friction between the cone and sleeve in the engaged position.
  • static friction will tend to resist rotation up to a point.
  • the static friction will be such that a relatively low level of applied torque may be resisted through the static friction, but exceeded on application of a greater torque, such as may be applied by the freight device making substantial contact with a solid object.
  • a greater torque such as may be applied by the freight device making substantial contact with a solid object.
  • such an applied torque maybe sufficient to overcome static friction and so permit rotation of the cone within the sleeve. If static friction were not overcome, the substantial applied torque in this example may be distributed to the point of attachment between the cone and the adapter frame.
