Definitions

  • This invention relates to a loading and unloading bridge for manipulating products, such as fruits which can resist only for a very short time temperature fluctuations, and which has to be trans­ported from a ship to a shed, or vice versa, where an adjusted tempera­ture or humidity degree is provided, which loading or unloading bridge is equipped with a beam for moving crabs, which beam is composed partly as a boom which can be positioned above the hold of the ship to be loaded or unloaded.
  • a loading and unloading bridge formed by a portal for transporting heavy loads in workshops which is equipped with a track extending around said portal is known from patent FR 397 759, filed on December 21, 1908.
  • thermally insulated transport boxes which allow to manipulate specific loads such as bananas under good conditions. These known devices are not suitable for loading and unloading boxes stacked on pallets and containing the fruits mention­ed in the preamble, at an increased speed. Usually, the dimensions of the boxes determine also the dimensions of the pallets.
  • the invention has for object to load and unload such goods stacked on pallets at exceptional, up to now unkown speeds.
  • said beam is provided with a loop-shaped track for said crabs in such a manner that moving a crab to and fro on one and the same section of said track is avoided and that several crabs can be moved along said loop-shaped track.
  • an arbitrary series of posts where said crabs can be stopped are provided along said loop-shaped track, which are equipped with approaching switches, whilst at least one section of said loop-shaped track is provided as a waiting or standby section located downstream a post where the crab is stopped above the ship's hold.
  • the necessary switches and/or crabs can be radio controlled.
  • the loading and unloading bridge comprises thus a usual portal 1, the concept and the structure of which are adapted to local requirements.
  • a beam 2, with respect to which a boom 3 is hingedly mounted, is fixed hereon.
  • the boom has to be able to hing or has to be able to be brought above the ship by means of any other conceivable structure.
  • the ship's hold has been indicated with general reference 5 and the ship's hatch with reference 6.
  • the level on which there is worked in the phase shown by Figure 1 has been indicated with the letter N. Stacked goods in the form of boxes carry reference 7.
  • the goods are loaded at said level onto pallets 8.
  • the pallets 8 can also belong to pallet cages 9. Moving each of the pallets or pallet cages, suspended from hoisting cables 10, up and down is realized from a crab 11.
  • beam 1 with its boom 2 are equipped with a loop-shaped track 12 ( Figure 2) allowing to use simultaneously several crabs.
  • the loop-shaped track 12 can be designed as a monorail from which the crabs 11 are then suspended.
  • the proper monorail can also be replaced by a box girder.
  • the invention idea consists thus essentially in moving several crabs always in the same direction along the loop-shaped track 12. Each crab with a loaded pallet can then be moved from the place above the hatch to an arbitrary unloading place whilst a following crab can take the available place above the hatch as soon as the previous crab has been removed from above the hatch.
  • a part of the loop-shaped track 12 is designed as waiting or standby section for one or more crabs.
  • Post A indicates a place above the ship's hatch in which there can be loaded or unloaded.
  • the ship is supposed to be unloaded.
  • a crab is thus situated in post A from the moment the crab reaches this post to the moment this post is left by the same crab. Between these two moments the unloading or the loading takes places. The here described example is thus about an unloading process of the ship.
  • the hoisting-cable is risen with its loaden, pallet 8 or pallet cage 9 until the moment the crab 11 may leave post A into the direction of post B.
  • Post B is an arbitrary or a predetermined place which is determined to be the most appropriate for unloading the goods.
  • the respective crab can go further along the loop-shaped track 12 until it reaches post C.
  • Post C can be the beginning of the waiting or standby section which extends upto post D.
  • Post C may also indicate the place from which the speed at which a crab moves, is lowered and/or this crab is slowed down.
  • the necessary detection means are also proyided for detecting the bends of the loop-shaped track 12 whereby the crabs take these bends at a lowered speed.
  • the loop-shaped track can be covered partly or completely.
  • the crabs have such a structure that a faulty crab can be replaced quickly and easily by another one.
