Definitions
- the invention relates to a crane according to the preamble of claim 1.
- the crane according to the invention is particularly suitable as a gantry crane for container operation, in particular for unloading and loading ships, the spreader between the containers being lowered into cable shafts at short intervals. It is also possible to transport containers in pairs in the so-called twin-twenty transport.
- Container bridges are getting longer and longer boom heights, which have to be covered by the boom. This systematically leads to a higher weight of the cranes and is associated with increasing costs for the crane construction as well as for the rail foundations on which the container bridges move. Furthermore, there is a tendency to have several containers side by side on one spreader, in the twin-twenty transport system transport. Since the containers can have very different loads, the stability on the spreader is achieved by a wide rope system with a large fixed point distance.
- Booms of container gantry are currently z. B. executed as a mono box carrier with about 4 mx 2 m, the cat is arranged according to the function hanging.
- the load capacity of the trolley is dimensioned with these container gantry cranes to a load of up to> 60 t, whereby the weight of the trolley is 60 to 80 t depending on the version.
- the cable drums which are arranged on both sides of a drive, have catchy grooves, with winding and unwinding from the center to the sides of each cable drum, the cables running apart in a V-shape when being unwound.
- the fixed point distance between the ropes can be so large that a considerable freedom of movement is required for the rope guide, which means that the crane can only be used to a limited extent is. Every increase in the extension of the jib and the ship height to be covered leads to a further disproportionate reinforcement of the steel structure and to the increasing load of the crane on the foundation of the port.
- DE 41 42 779 A 1 shows a hoist on the trolley of a container crane, which was developed by reducing the width of the container crane, which also leads to weight reductions and the double-acting cable drums are arranged on different axes.
- the document does not show how the hoist is arranged on the trolley of the container crane.
- the arrangement of the trolley on the jib of the container crane cannot be seen either.
- the solution according to the invention provides a crane designed as a gantry crane for general cargo operation, with which it is possible to stably transport containers, also two containers each with different loads, on a spreader or to insert this spreader into a shaft with small dimensions without the Ropes for the spreader require a lot of space on the side, whereby the container crane with its jib can run over very high and wide container ships.
- This is possible with a low load on the container bridge, primarily because the solution according to the invention shows ways of increasing the lifting height of the container crane without its own height and thus the weight increasing.
- the solution according to the invention provides that the rope drums arranged side by side wind up or unwind the ropes with two gears side by side, each rope drum having only a right-handed or a left-handed rope groove pitch and the winding direction of both rope drums running in the opposite direction.
- the four ropes of the two rope drums of the crane run from the rope drum over deflection points of the load handling device, which can be designed as a spreader, the deflection points representing deflection rollers to the fixed rope point on the trolley frame.
- trolley frame so that it can move over the double box girder of the crane, the cable drums being arranged above the trolley frame and the cables passing through the trolley frame and between the double box girders.
- FIG. 3 perspective view of the invention
- Cable drum arrangement with a trolley which can be moved on the double box girder
- FIG. 4 shows a schematic diagram of the rope drum according to the invention with a wire guide in a shaft between containers
- Fig. 6 schematic representation of the rope drums according to the invention on a single-arm boom.
- FIG. 1 shows the crane according to the invention as a container bridge 1 for transporting a container 2 on a spreader 9 with deflection rollers 10, of which cables 7 lead to the machine house cat 4, on which two cable drums 5 are arranged on an axis and four cable fixed points 8.
- the nacelle 4 moves with wheels 6 on two double box supports 3. Because the nacelle 4 is standing on the
- Double box carrier 3 moves, the lifting height for container 2 can be increased without having to increase the entire height of the container bridge 1 relative to the quay.
- FIG. 2 shows twin-twenty containers 12 on a spreader 9 with rope pulleys 10.
- the center of gravity 13 of these containers 12 is particularly off-center when the containers have different loads, so that the spreader 9 must be particularly stable.
- the two two-speed cable drums 5, between which a drive 16 is arranged, enable a crab frame 20 to be held tightly in that the cables 7 are wound up and unwound in a two-way manner next to one another.
- the ropes 7 are guided through the trolley frame 20 over the double box carrier 3.
- the entire boom width is within the interference edge 21.
- FIG. 6 shows a monocoque carrier 22 on which a nacelle 23 is suspended, the parallel ones
- Rope drums 5 are arranged side by side. In this example, too, a more compact design is made possible, in which a larger fixed point distance is achieved with the same design.
