Definitions

  • Opposed spreader beams are telescopical coaxially in and out of each other and are supported from and telescoped in a fixed center beam.
  • the present invention is concerned with a type of spreader capable of handling a variety of types and sizes of cargo-containers which. as a complex of containers and container handling equipment in the transportation industry. has become to be known containerization.
  • This term embraces the concept of transporting freight packed in large crane or vehicle portable containers from the shippers dock to the consignees dock by any type of carrier, or by different carriers, without intermediate opening of the containers or any handling of the goods in less than container load quantities.
  • a desirable pick-up arrangement for a container resides in cooperating construction of a container and a spreader which enables coupling of the container and the spreader at the extreme upper corners of the container.
  • coupling has generally been at the extreme corner sections of the upper horizontal surface ofthe container by means ofconnecting means. known as twistlocks.” which project downwardly from the four corners of the spreader.
  • Differences in cargo-container lengths have necessitated either the use of independent spreaders of different sizes or of an expansible spreader capable of adjustment to various lengths, for use with straddle carrier type vehicles, lift trucks or crane equipment capable of engaging and transporting by means of the spreader such cargo-containers. e.g., at freight terminals at which the capability for receiving all available types and sizes of containers for delivery or forwarding further along respective routes of shipment is important. Differences in container lengths have been adopted to accommodate inevitable differences in the size of shipments, the size of carriers. and other factors, in order to contribute flexibility and economy to the handling of freight. particularly in view of standardization of the height and width of all such containers.
  • the Rubery Owen and Star Iron and Steel spreaders generally comprise two sliding beams, offset from the centerline of the container in side-by-side relation, and which can accommodate containers from 20 to 40 feet in length.

  • SUMMARY My invention comprises an improved spreader frame of relatively simple construction, low cost and minimum bulk, providing maximum flexibility in engaging and transporting a wide variety of container types including container pick-up capability in relation to a variety of corner casting configurations. It is therefore a primary object of the invention to provide a relatively simple and low cost spreader frame having greater flexibility than heretofore to handle a variety of existing container types now in use.
  • An important object is to provide coaxial telescopic spreader frame means capable of extension to engage containers of at least twice the length of containers engageable at full retraction of the spreader frame means.
