Abstract
Description
- The invention is related to a ship to shore crane installation, in particular for handling containers, comprising a crane support structure having a water side support and a land side support, the water side support having at least one support beam and legs carrying the at least one support beam at an elevated level above a surface, as well as at least one crane travelling along and supported by the crane support structure, said crane having a bridge girder extending transverse below the water side support, a boom girder connected to the bridge girder, a frame on top of the bridge girder and pulling means extending between the frame and the boom girder for displacing the boom girder between an active position generally aligned with the bridge girder and an inactive position swung upwardly, and a trolley travelling back and forth on the bridge girder and boom girder for transferring a container.
- Such a crane installation is disclosed in
EP-A-1923338 . The water side support and the land side support of said crane installation each have a support beam which extend in a parallel fashion at the same level above the surface. At regular distances, these support beams are connected to the top end of multiple legs. As the girder structure of the cranes extends beneath the support beams, the trajectory over which the cranes are displaceable along the crane support structure would be limited to the pitch of the legs. In order to circumvent this limitation, the girder structure of the cranes or the rails along which the trolley travels, are provided with removable sections so as to allow the boom structure to pass the legs. - As a result of the fact that the cranes are situated on a crane support structure which is at an elevated level, it has become possible to arrange the cranes at a more closer distance next to each other. Thereby, the advantage is obtained that directly adjacent bays of a container ship are simultaneously accessible. This means that the containers held in these bays can be handled in a more versatile way, such that loading and unloading of a containership can be carried in a more rational manner and at a greater speed.
- Although several advantages are obtained by this prior art crane installation, the limitation of movement of the cranes, or the provision of removable sections in the girder structure thereof, or the provision of removable rail sections, represent severe disadvantages. The construction of the girder structure or rails with removable sections is rather complicated and vulnerable. Malfunction of said sections would limit the availability of the crane to a particular section of the crane support structure only.
- The object of the invention is therefore to provide a ship to shore crane of the type envisaged before, which allows the advantages to be obtained as described before, however with the additional advantage of a simpler and more reliable crane construction. This object is achieved in that the water side support comprises at least two separate support beams which are at a distance from each other and which are directly connected to each other by interconnection means, such as by truss members or by a web, forming a support girder. The length of the support girder may preferably be equal to or larger than the service length of the container ship.
- The beams of the crane support structure constitute a strong water side support girder. This support girder has a high bending stiffness as a result of the fact that the extreme parts of such support girder are at a relatively great distance from the neutral line thereof. Thereby, it has become possible to select a large spacing or pitch of the support legs of the support girder. In case a suitable position of the beams with respect to each other is selected, having regard to the major loadings to which the girder is exposed, a very high bending stiffness is obtained. Thus, the pitch of the legs of the crane support structure can be greatly increased, to such en extent that only legs near the very ends of the support girder need to be provided. As a result, the cranes can be displaced along the full length of the support girder, without the need to remove sections from the boom structure.
- The support girder has relatively large cross sectional dimensions as a result of the appreciable lateral distance of the interconnected beams which thus are able to provide the stiffness and strength required. This large cross sectional size can be matched to the dimensions of the frame, in that said support girder may completely fit through the frame. For instance, the height of the water side support girder may be of the same order of magnitude as the height of the frame or pylon thereof, preferably between 60% to 90%, more preferably 70% to 80%, of the height of the pylon.
- Preferably, the support beams are located at different levels. In particular, the boom sections may be positioned vertically above each other, in such a way that a support girder is obtained with a high bending stiffness with respect to vertical loadings. Preferably, at least three support beams are provided whereby the support girder has a triangular-like cross section. Such support girder has a high bending stiffness with respect to both horizontal and vertical loadings, as well as a high torsion stiffness. Other cross-sectional shapes, such as with four or more sides, in particular rectangular or square, are also possible.
- The frame may have a pylon which extends upwards from the bridge girder and which is located near the hinge construction, and a tension member extending from the top of the pylon towards the land side of the bridge girder. The support girder extends through the area defined between the bridge girder, the pylon and the tension member.
- The cranes may be supported with respect to the support girder through a water side wheel support which is fixed to the bridge girder and which is supported in a rolling fashion along a track provided on one of the beams of the support girder. Preferably, the track is provided on the beam which is situated at a level lower than the level of an other beam.
- Furthermore, the land side support may have land side crane legs provided with a land side wheel support near the land side of the bridge girder. The crane support structure may have an elevated land side track which extends generally parallel to the support girder, whereby the land side wheel support is supported on said elevated land side track.
- The invention will now be described further with reference to the embodiment shown in the drawings.

Figure 2 shows a cross section through the installation. -
Figure 3 shows a front view. -
Figures 4a-c show details of the support girder. -
Figure 5 shows a view on the crane support. - The ship to shore crane installation consists of a crane support structure generally denoted by 1, and a plurality of
cranes 2 which are arranged on the crane support structure. The crane support structure is situated on aquay 3, bordering a harbor 4 forcontainer ships 5. The container ship carriescontainers 6 which are arranged according to bays 7. Each bay may contain stacks of containers which are arranged parallel to each other in the longitudinal direction of thecontainer ship 5. - The
cranes 2 are positioned above a specific bay for unloading/loading containers 6. As shown, the cranes can be positioned close to each other so as to handlecontainers 6 in directly adjacent bays 7. To that end, the cranes should have a limited overall width. This limited width is made possible by the specific layout of thecrane support structure 1 as will be explained below. - The
crane support structure 1 is constituted by the waterside support girder 8 which at its opposite ends (only one of which is shown infigure 1 ) is supported with respect to the surface of thequay 3 by means ofcolumns 9. This means that except for thesecolumns 9 at the opposite ends of thesupport girder 8, no further columns are present in the intermediate region of the support girder. As a consequence, thecranes 2 can be displaced over the full length of thesupport girder 8 thereby enabling a flexible use thereof. - The
support girder 8 consists, in the embodiment shown, of atop beam 10, abottom beam 11 and anintermediate beam 12 which define a triangular like cross section. The beams 1-12 are interconnected by several types oftruss members figures 4a-c . - The
cranes 2 each have agirder structure 15, consisting of thebridge girder 18 andboom girder 19 as well as aframe 17 which is positioned on top of theboom girder 18. Theboom girder 19 is connected to thebridge girder 18 through a hinge construction 31, and is displaceable between the operative position shown in full lines, and the inactive, hoisted position shown in dotted lines by the pull member 32. Theframe 17 is connected to thebridge girder 18. Theframe 17 comprises avertical pylon 21 and atension member 22 which extends between the top of thepylon 21 and the land side of theboom 16.Further tension members 23 applied in a known manner. - According to the invention, the complete construction of the
support girder 8, that is thetop beam 10, thebottom beam 11, theintermediate beam 12 and thetrusses bridge girder 18. In fact, the support girder extends through theframe 17. Thereby, the option is obtained to make the crane travel in an uninterrupted fashion from the one extreme end of the support girder to the other extreme end thereof. - The
pylon 21 carries a number ofcrane travelling mechanisms 24 each provided with a number ofwheels 25. Thewheels 25 are supported in a rolling fashion on atrack 26 which is available on thebottom beam 11 of thesupport girder 8. Thesupport structure 1 furthermore has an elevatedland side track 29, supported bycolumns 16, over which theland side wheels 28 provided near the lower end of thecrane legs 28 can be rolled. Thus, the cranes are supported by means of thewater side wheels 25 over thebottom beam track 26, and by means of theland side wheels 28 over the elevatedland side track 29. - In a known manner, a
trolley 30 is displaceable along theboom structure 16 for transferringcontainers 6 between thecontainer ship 5 and thequay 3. -
