Definitions

  • a container cargo vessel provided with a plurality of longitudinal holds for each deck with at least one vertical lift to serve each longitudinal hold, longitudinal conveyors for each longitudinal hold, an intermediate conveyor for each lift, and power mechanism for operating the lifts and conveyors.
  • the holds, conveyors and liftS are arranged so that the cargo vessel may be loaded and
  • a The invention relates to a container cargo vessel equipped with containers and having means for the stowage and securing of the containers in the holds of the vessel.
  • a vessel of this kind is already known, inter alia, from the publications regarding the Lautovick system.
  • the containers are loaded via a raft port, in the course of which they are transported to the various decks via loading bridge of adjustable height situated on the quay, which loading bridge is provided with conveyors.
  • a pallet lift is incorporated amidships in the loading stage, provided with a roller track with connecting rollers tracks athwartships on each middle deck.
  • the pallets are lifted from the roller tracks by means of pallet trucks or forklift trucks, conveyed in the transverse and longitudinal directions and subsequently stowed by man-power in the hold.
  • the upper deck is provided with a number of loading stages whose breadth, or whose collective breadths covers the entire breadth of the vessel once or several times, while in the holds longitudinal conveyors are similarly installed over the entire breadth ice of the vessel, on which conveyors the containers are loaded via the loading stages and stowed in the holds below deck.
  • the containers can be placed directly on the hold conveyors. It is even possible to place several containers one above the other, although the number is limited on account of the great pressure upon the lowermost container. As a rule not more than two containers can be placed one above the other, so that for larger vessels several loading levels are necessary.
  • the upper deck must be practically entirely open, i.e., it must have loading stages extending as far as possible in the longitudinal and transverse directions.
  • the longitudinal strength which is normally taken by the upper deck must in this case be obtained in a different manner and this involves serious difliculties for large vessels.
  • the subject invention provides the holds with a number of hold conveyers built one above the other to serve every loading level.
  • the hold conveyers are interrupted at the loading stages, and one or more intermediate conveyers may be installed in the loading shaft at each loading level.
  • the intermediate conveyors may be installed at the various loading levels by means of a crane, or may be made to fold back at each loading level. Both possibilities shown the drawback that the crane driver will no longer have a good view if the containers have to be installed deep in the hold on the intermediate conveyors.
  • loading and discharging of the containers by means of the crane is the most important operation, since the total loading and discharging time of the vessel is decided by it.
  • the invention not only aims at rendering it possible to load and discharge containers with preferably only one man in the crane cabin and one man in the vessel, ⁇ but also aims at shortening the total loading and discharging time to the utmost possible extent.
  • the intermediate conveyors are installed on a lift that can move up and down in the loading shaft.
  • the lift is situated at deck height, while simple means ensure that the crane driver can place the containers in true position on the intermediate conveyors. Uncoupling can be effected from the crane. After the lift platform has been fully loaded, it descends to the desired loading level at which all the containers are simultaneously transferred via the intermediate conveyors to the hold conveyors. In this operation the crane can continue without interruption to load another lift platform, for which purpose the containers need not all be of the same length. This should be the case however, for each lift load. For this purpose the containers are first connected on the intermediate conveyors to the previous load, after which the entire transport is effected simultaneously until the last containers added are clear of the lift. Then comes the next load, and so on. The length of the containers is therefore of no importance.
  • the operations are performed in the reverse order, during which the discharging time may be shortened considerably, as the containers are first brought on deck by the lift and can afterwards be quickly removed by means of cranes.
  • a lift of this kind offers the advantage that the platform is rigidly enclosed and can be fixed precisely in position at each loading level.
  • the vessel with a number of longitudinal watertight bulkheads while recessed loading stages are provided between the plating and a longitudinal bulkhead and in between the longitudinal bulkheads over the entire length of the hold and are scarfed to each other in such a way that the longitudinal strength of the upper deck is not impaired by the loading stages.
  • the loading levels prefferably be Separated from each other by watertight decks.
  • the intermediate conveyors are installed on the watertight middle deck hatches.
  • the requirements specified for watertightness may also apply to the container.
  • the watertightness may also apply to the container.
  • the watertight compartments required for safety are obtained by making the containers watertight and providing them with watertight doors.
  • the vessel can be built at a considerably lower cost, as in this case the watertight compartments and middle decks may be omitted.
  • hold stays are provided at container breadth or a multiple thereof which stays are connected with cross-girders at container height or a multiple thereof, while in the longitudinal direction they are interconnected by longitudinal conveyors together forming a spatial framework which gives the vessel very great strength and rigidity.
  • the vessel can be built at much lower cost. Middle decks and bulkheads are then superuous and the upper decks with smaller loading stages may consequently be lighter and cheaper. Thanks to the compact support, a large number of containers can without objection be taken on deck.
  • the container cargo vessel may be equipped with cheaper and more suitable conveyors.
  • the intermediate conveyors and the hold conveyors are composed of a number of frames, provided at top and bottom with chutes having driven sprocket wheels at one end and return sprocket wheels with intervening chains at the other end, which chains consist of long-linked plate chain with carrier sleds between the plates and provided at topand bottom with interchangeable sliding surfaces whose shape is matched with the shape of the chutes.
  • the driven sprocket wheels on the intermediate conveyors have one or more common driving spindles which can be driven by one or more driving -mechanisms situated on the lift, 'which spindles have one or more driving gear wheels.
  • the driving spindles of the hold conveyors are likewise provided with driving gear wheels having movable coupling gear wheels which can be moved into the shaft of the lift in such a manner that the coupling gear wheels automatically engage the driving gear wheels on the driving spindles of the intermediate conveyor when the lift arrives at the appropriate loading level.
  • a sled conveyor for a vessel is far more advantageous than a roller track 'because there is always a certain amount of play on the sprocket drive of a roller track, which means that the containers, on account of the movements of the vessel in the longitudinal direction, have to be very soundly secured.
  • this securing or sea-proofing of the containers is preferably effected by providing the vessel with blocking devices consisting of longitudinal side tracks positioned on one or both sides of each loading level, provided with levers which are elastically connected with the stays or other members of the spatial framework, so that the guide tracks can be moved in the longitudinal direction with or without a centrally controlled driving device, in such a way that if, for instance, the guide tracks are pulled, the levers press them against the containers, as a result of which the latter are brought into sea-proof connection with the vessel.
  • the containers thus connected with the vessel formas it were a ship ⁇ with a large number of small watertight compartments. If these compartments are filled with liquids or withbulk goods then there is no danger of the cargo shifting in the event of a heavy list of the vessel.
  • the container cargo Vessel described in the foregoing therefore cannot suddenly capsize as does happen withv bulk carriers and other vessels. Vessels for the conveyance of special cargo or ships with deep tanks, refrigerator holds, etc., may consequently be replaced by a uniform container cargo vessel equipped with containers which are adapted to the cargo to be carried.
  • the crane takes one or more containers from the lift to the wharf and brings back one or more containers from the wharf to the lift to be deposited at the place just emptied.
  • the crane is thus loaded in both directions.
  • the discharging berth under the crane can in this case be divided into halves. On one-half the straddle carriers being the containers to be loaded (e.g., as close as possible to the vessel) and on the other half they take back with them the containers discharged by crane from the vessel for conveyance to the container terminal. 'Ihis transport, too, is thus rendered much cheaper.
