Definitions

  • the invention is related to a ship to shore container crane comprising a gantry structure, a boom supported with respect to said gantry structure, said boom in an operating position extending between a ship facing end and a shore facing end, trolley means movably supported along the boom in said operating position, two coupling means such as two spreaders, at least two cable hoisting means extending between the trolley means and a respective couplimg means, as well as an operator's cabin suspended from said trolley means.
  • the object of the invention is therefore to provide a ship to shore container crane of the type described before by means of which a reduced handling period for loading or unloading of a container ship can be obtained, and which on the other hand provides the possibility to exert the required control on said containers.
  • This object is obtained in that, in a direction parallel to the boom, one of the cable hoisting means is positioned on one side of the control cabin, and the other cable hoisting means is positioned on the opposite side of the cabin.
  • a first advantage of the crane layout according to the invention is the close proximity of the cabin, and thus of the operator or driver, with respect to the coupling means, such as spreaders, hooks etc., and containers suspended from the adjacent trolleys.
  • This proximity offers a sufficient view of the operator on the container and spreader which are being positioned and coupled or uncoupled.
  • the distance between the cable hoisting means is preferably relatively small, e.g. in the order of 2-5 times the width of a container. Said width should be large enough to provide a safe distance between the operator's cabin and a lifted spreader/container, but small enough to provide the required view for the operator on both spreader/container combinations.
  • this control is possible through one operator only.
  • Such single operator control is further promoted by providing a cabin which is rotatable about an essentially vertical axis. The cabin is thus rotated towards the spreader/container being handled; subsequently the cabin can be rotated towards the other spreader/container.
  • a further important advantage of this embodiment is that, under the control of one operator only, two containers can be handled quasi-simultaneously, which leads to the desired, more efficient process of loading/unloading of a ship.
  • the trolley means may comprise two interconnected trolleys, each of said trolleys being provided with a respective cable hoisting means.
  • the trolleys may be interconnected e.g through a beam structure or any other suitable connection, the cabin being suspended rotatably between the trolleys, e.g from the middle of the beam.
  • the trolley means may comprise a single, unitary trolley from which the hoisting means with the cabin in between are suspended.
  • the invention is moreover related to a method of handling containers by means of a ship to shore container crane comprising a gantry structure, a boom supported with respect to said gantry structure, said boom in an operating position extending between a ship facing end and a shore facing end, trolley means movably supported along the boom in said operating position, two coupling means such as spreaders and at least two cable hoisting means extending between the trolley means and a respective coupling means or spreader.
  • said method comprises the steps of:
  • This gain in handling time is also made possible by the fact that the handling process can be carried out simultaneously both under automatic, preprogrammed control and under operator control. This can play a role for instance under the circumstance that the process of lifting one of the spreader with container is continued while the other spreader is positioned on the other container. Said step of lifting the one spreader with container can then be carried out under programmed, automatic control, while the process of positioning and coupling the other spreader and container can be carried out under operator control, thus alleviating the operator's task of handling two containers.
  • the method according to the invention may comprise the steps of:
  • the method according to the invention may comprise the steps of:
  • a time gain can be obtained by the steps of:
  • the operator has always the required view for handling the spreaders and containers, by rotating the cabin towards a respective spreader before positioning said spreader on a respective container. Furthermore, the cabin can be rotated towards a respective spreader with container coupled thereto before positioning said respective spreader with container with respect to the target location.
  • Figure 1 shows a ship to shore container crane according to the invention in side view.
  • Figure 2 shows an enlarged view of the trolley means with double cable hoisting means and rotatable cabin according to the invention.
  • Figure 3 shows a front view of said trolley means.
  • the ship to shore container crane as shown in figure 1 comprises, in a known way, a gantry structure 1 and a boom 2 supported on said gantry structure 1.
  • Said boom 2 comprises a fixed boom part 3 as well as a rotatable pivoting boom part 4.
  • this pivoting boom part 4 is supported.
  • the boom 2 is shown in full lines in its operating position extending between a ship facing end 6 and a shore facing end 7.
  • the gantry structure 1 is supported on a quay 8 by means of rails 9 and wheels 10 so as to be displaceable along a ship 11 moored to the quay 8.
  • the ship 11 carries a load 17 which consists of a large number of containers 18 stacked upon and next to each other in a known way.
  • the boom 2 comprises two boxlike girders 12, 13, onto which the trolley structure 14 is displaceably supported. This is obtained in a known way by means of rails 15 mounted on said boxlike girders 12, 13 and wheels 16 mounted to the trolley structure 14.
  • the trolley structure 14 consists of two pairs of trolleys 19, 20 which are interconnected by the beam 21.
  • This layout can also be considered to represent a single, unitary trolley.
  • this beam is shown as a box type beam, but the construction of said beam can be of any type, such as a lattice structure.
  • two cable hoisting means 22, 23 are suspended, each comprising cables 24 shored over the trolley sheaves 25 and sheaves 26 which are accomodated in the head block 34 mounted to the spreader 27.
  • Such cable hoisting means 22, 23 are known per se, and will therefore not further be described.
  • an operator's cabin 33 is suspended from the beam 21 by means of column 29. According to the invention, said cabin 33 is rotatable about a vertical axis through the slewing ring 30.
  • the trolley structure 14 is put in a position above the container load 17 of the ship 11.
  • the cabin 33 is rotated such that the operator is facing said ship facing end 6 as well.
  • the operator has the required view on the spreader 28 situated on the ship facing side of the trolley structure 14.
  • Said spreader 28 is then lowered by the corresponding cable hoisting means 23, and the spreader 28 can be positioned just above the container 32 in question under operator control.
  • the spreader 28 is coupled in a known way to said the container 32, in such a way that said spreader 28 together with container 32 can be lifted by means of said cable hoisting means 23.
  • the cabin 33 is rotated over about 180°, in such a way that the operator gets the required view of the spreader 27 positioned on the shore of facing end of the trolley structure 14.
  • the operator is able to position said spreader 27 just above the container 31 in question, and to couple said spreader 27 to said container 31.
  • the other container 32 has been lifted to such a height that it cannot collide with neighbouring structures when moving the trolley structure 20 somewhat along the beam in the process of positioning the shore facing spreader 27.
  • the further lifting of the other container 32 can however largely be carried out under automatic control, which means that the operator, after initiating the lifting process of said other container 32, can turn his attention towards the process of coupling the shore facing spreader 27 to the container 31 in question.
  • the process of lowering the containers 31, 32 will be started.
  • the operator's cabin 33 will be in such a position that the operator faces the quay, which makes that he will be able to control the lowering of the spreader 27 together with the container 31.
  • the process of lowering the other spreader 28 with container 32 will be temporarily halted. This means that the operator can concentrate on placing the container 31 at the desired location on the quay 8.
  • the spreader 28 is uncoupled and lifted the way. Subsequently, the cabin 33 is rotated such that the operator can view the ship facing spreader 28 with container 32. The operator can now concentrate on positioning said container 32 on the desired location. After the container 32 has been positioned in such a way, the spreader 28 is uncoupled and lifted away. Subsequently, both spreaders 27, 28 can be lifted fully under automatic control, and a new cycle of unloading two containers from the shipload 17 can be commenced.
  • coupling means carried out as spreaders also other coupling means can be used such as hooks.
  • the hoisting means can be connected to a head block 34 each, known per se, which head blocks 34 each comprise a number of sheaves 26 over which the several loops of the hoisting means are guided.
  • the coupling means such as spreaders 27, 28 can be mounted.
