Description

The invention relates to a port crane, in particular mobile harbor crane, with an undercarriage and an upper carriage mounted on the undercarriage, which is preferably rotatably mounted on the undercarriage, wherein the undercarriage is modular in such a way that the undercarriage via modular adapter components with different suspensions optionally connectable is that the selected chassis is formed on the undercarriage as a conventional undercarriage undercarriage, and the conventional undercarriage chassis has a clear space which is so small and dimensioned that no container transport vehicle and no conventional truck can pass underneath the undercarriage without collision.

A crane, which in this sense has a modular undercarriage, which can be connected to form a conventional undercarriage optionally with a wheel or crawler chassis is, for example, in the German patent DE 30 13 513 C3 and the European patent application EP 1 209 118 A1 described.

From the US patent publication US 3,638,805 A In addition, a crane with a conventional undercarriage chassis is known, the crawler chassis is releasably secured and exchangeable for a wheel gear.

From the DE 199 44 927 C2 For example, a so-called mobile harbor crane is known. These harbor cranes have conventional undercarriage suspensions, for example in the form of undercarriage tire undercarriages or undercarriage crawler tracks, and are called mobile harbor cranes.

If the corresponding port cranes have a portal chassis in the form of a portal tire chassis, portal rail chassis or portal crawler chassis, they are called port gantry cranes accordingly. Their chassis and their classification, ie lifting capacity or load capacity, are each adapted to the intended use, ie, such port cranes are so essentially in terms of their purpose and the customer's wishes custom-made.

In this context, under a conventional undercarriage chassis understood a chassis that has a small clear space below the undercarriage. In contrast, under a gantry undercarriage is understood a chassis that has a large clear space below the undercarriage, which is designed and dimensioned so that it can be used as a passageway for the prevailing in a container terminal or quay traffic. The clear space of the gantry is in this case essentially defined by two spaced apart and vertically extending portal supports of the gantry, in particular by their distance from each other and their length between their bottom facing the bottom and its opposite upper end. This makes it possible in particular that, for example, container transport vehicles that are loaded with a container, or conventional trucks at least one lane or on two parallel lanes collision freely under the portal chassis or between its portal supports can drive through, thus undercut the portal chassis or undercarriage to be able to. Conversely, by means of such a portal undercarriage, due to the large clear space, which is large in comparison with conventional undercarriage undercarriage, corresponding vehicles can be run over below the undercarriage in a collision-free manner. Also, under the portal chassis or between the portal supports rail traffic can be performed. All this is not possible with a conventional undercarriage chassis, since its clear space below the undercarriage is not designed to be large enough.

From the prospectus "Generation 5 - Harbor Crane Model 8" of Gottwald Port Technology GmbH, Dusseldorf, Germany, it is known from page 5, the respective port crane to produce port construction, ie. The superstructure with tower and outrigger are each available with different undercarriages. As undercarriage types are described in addition to a frosted version, a gantry design with rail chassis and a use on a pontoon.

More cranes are out of the WO 97/29945 A1 , of the EP 2 377 801 A1 , of the US 3 280 931 A , of the US Pat. No. 3,638,805 A as well as the DE 100 09 736 A1 known.

In contrast, the object of the present invention is to provide a To provide improved port crane, which is in terms of the chassis, which are connectable to the modular undercarriage, easily adaptable to different uses and circumstances.

This object is achieved by the port crane recited in claim 1. In the dependent claims 2 to 9 advantageous embodiments of the invention are given.

According to the invention, a harbor crane, in particular mobile harbor crane, with an undercarriage and with an upper carriage mounted on the undercarriage, which is preferably rotatably mounted on the undercarriage, wherein the undercarriage is modular in such a way that the undercarriage via modular adapter components with different suspensions is selectively connectable in that the selected undercarriage on the undercarriage is designed as a conventional undercarriage undercarriage, and the conventional undercarriage undercarriage has a clear space which is so small and dimensioned that no container transporting vehicle and no conventional truck can travel underneath the undercarriage without collision, thereby improving that the undercarriage via modular adapter components alternatively with different suspensions is optionally connectable such that the selected suspension is formed on the undercarriage as a portal chassis and the portal chassis a clear space a ufweist, which is designed and dimensioned so that container transport vehicles that are loaded with a container, or conventional trucks can drive at least one track collision-free under the portal gear or between its portal supports through, thus underrun the portal chassis, and that the undercarriage a central, box-shaped component having in addition to a turntable at its end faces and / or its longitudinal sides and / or its underside connections for the modular adapter components. Thus, the port crane is modular in terms of trained on the undercarriage chassis and can be adapted by changing the individual modules and adapter components used for the undercarriage in the simplest way to the intended use and customer requirements, such as the customer necessary spans the trolleys and the desired clear space below the undercarriage. Due to the corresponding modular design of the undercarriage, the undercarriage, the formation of a navigable under traffic portal landing gear allows the port crane to be adapted to the circumstances of the place of use. In this way, the traffic routes can be optimized to save space and improve the accessibility of the immediate vicinity of the port crane in smaller container terminals and cramped quayside. In addition, certain mass production aspects can be incorporated into the production of the undercarriage or the components or adapter components and modules, which allow a more rational production.

In the preferred embodiment, the undercarriage has a central, box-shaped component, which has connections for the modular adapter components and / or modules in addition to the turntable on its end faces and / or its longitudinal sides and / or its underside. Around this universal component so the undercarriage is built by the modules or adapters are attached to the terminals. In the simplest case, the connections are connection surfaces for welding the adapters / modules.

The undercarriage is thus built around an always same central component around by means of the adapter components and other modules attached thereto. The modules are thus either directly or as the respective chassis by means of adapter components attached to the central component to build the entire undercarriage.

In a structurally simple manner, it is provided that two main side trusses are connectable to the undercarriage to form the gantry, which are selectively connectable to one of the different suspensions, preferably with a tire suspension, especially in the form of frosted, individually steered and height-adjustable pendulum axles, or with a Rail chassis to form gantry portal gantries.

In an advantageous manner, it is further provided that one of the vertically extending main side chassis carrier can be connected to the central component on both end faces of the horizontally extending central component.

In a structurally simple manner is also provided that each main side chassis carrier via an adapter designed as modular Adapter member with the central component is connectable, wherein the adapter is preferably formed angularly and fastened via one of the terminals on the respective end face.

Thus, by using suitable angled adapter components, e.g. be realized in a simple manner with main side girders in gantry design. Alternatively, rails or tire suspensions may be posted to the portal thus created. In the case of the tire chassis, additional boom supports can be provided in the area of the chassis.

Advantageously, it is provided that trained to form the conventional undercarriage as a mounting arm or as a mounting bracket modular adapter components are connected to the central component to connect the undercarriage herewith either one of the different suspensions, preferably with a tire suspension, especially in the form of frosted , individually steered and height-adjustable pendulum axles or in the form of a conventional tire suspension, wherein the connection of the modular adapter components with the central component in particular via the connections on the longitudinal sides and / or the underside of the central component and / or connectable to both end faces of the central component head carrier is possible.

Accordingly, the central component can be provided with conventional tires tires. As an alternative, frosted individually steered and height-adjustable pendulum axles can also be used. These can be provided in addition to the two necessary chassis rows in a third row of chassis at the bottom of the central component.

It is also possible, depending on the chassis and intended use, that supports, in particular in the form of boom supports or outriggers, can also be attached to the undercarriage or to the central component via modular adapter components, and the modular adapter components preferably comprise one of the head carrier or a supporting structure, which is connectable to the head carrier or the central component ..

The same applies to the generator unit, which can be configured as a container-like module, so that it can be arranged either on the longitudinal or front or top of the undercarriage. For example, the arrangement of the generator unit on the front side or at the end of the undercarriage on the upper side in the design of the chassis as a conventional frosted suspension or with frosted individually steered and height-adjustable pendulum axles is possible. In the design in gantry design, the generator unit can be placed on the longitudinal side of the undercarriage or also at the end of the undercarriage on the top thereof. The generator unit is equipped with a self-powered power supply of the crane with a modular diesel engine, a generator, a tank and the corresponding peripherals. In an external power supply of the crane via a third-party feed accounts for the said components and it is instead a transformer with appropriate peripherals used, resulting in a reduction of the generator housing.

In order to provide a complete harbor crane kit, it is also desirable that the superstructure or its tower and boom are modular.

Preferably, therefore, the superstructure has a tower mounted thereon, which has a pivotable about a horizontal axis boom, the tower is modular by means of different hoists, luffing, boom, counterweights and electro-hydraulic units can be completed. The tower may also be adaptively (modular) in height.

In the FIG. 1 the concept for the modular construction of the undercarriage of a mobile harbor crane is shown with an exploded view.

The undercarriage can therefore be equipped or produced as required via modular adapter components with different suspension systems.

The undercarriage comprises a central, box-shaped component 1, which has in addition to the turntable 2 at its end faces 3 connections 4 for the adapter components and / or modules.

At the terminals 4 can either head carrier 5 or adapter 6 connect.

The head carrier 5 may be equipped with jib 7.

On the front side of the head support 5 or on the top of a generator housing 8 can be attached. Alternatively, the generator housing 8 can also be arranged via a support structure 20 parallel to the longitudinal side of the component 1, wherein the support structure 20 is attached to the underside of the component 1. Between component 1 and generator housing, a distance for a walkway 17th (see below).

Can be attached to the box-shaped component 1 as a conventional suspension chassis 22 or frosted individually steered and height-adjustable pendulum axles 9 laterally on the long sides.

The adapters 6 angle down from and serve to attach main side truss 10th

Depending on the use, rail carriages 11 or frosted individually steered and height-adjustable pendulum axles 9 are provided on the main side landing gear carriers 10.

The main side chassis members 10 may be equipped with end supports 12.

In addition, a modular platform framework 13 is provided which on the one hand comprises two part-circular platform extensions 14 and, on the other hand, stairs 15, ladders 16 and sidewalks 17.

Here are some examples of some of the many possible combinations of the modular undercarriage.

FIG. 2 shows a classic mobile harbor crane undercarriage UW 1. At the central box-shaped component 1 front end head 5 are welded, which are equipped with extendable boom supports 7. The one head support 5B also carries the generator housing 8 in container form.

In addition to the turntable 2, the part-circular platform extensions 14 are attached and at the other end face of the head support 5A is configured with the stairs 15 for access.

Laterally on the longitudinal sides of the box-shaped component 1 or the longitudinal sides extending and aligned with these areas 19 of the head support 5 are each frosted individually steered and height-adjustable pendulum axes 9 (here 5 each) arranged by means of welded fastening arms 18.

In the FIG. 2a a complete harbor crane is shown next to the undercarriage UW1 according to FIG. 2 includes a superstructure OW mounted thereon. In the FIG. 2 shown parts of the undercarriage UW1 are also in FIG. 2a shown and identified with the same reference numerals. The undercarriage UW1 has a conventional undercarriage undercarriage. On the superstructure OW a tower 24 is fixed, which has a pivotable about a horizontal axis boom 25. Here, the tower 24 can be completed modularly by means of different hoists, luffing mechanisms, outriggers, counterweights and electro-hydraulic units.

FIG. 3 shows a mobile harbor crane undercarriage UW 2 in portal construction. At the central box-shaped component 1 front end adapter 6 are welded, the main side chassis support 10 wear, which in turn frosted individually steered and height-adjustable pendulum axles 9 (here 5 each) are arranged on the lowermost cross member 10A. The two main side chassis members 10 form portal supports of the portal chassis. The gantries also include the trolleys, in the present case in the form of pendulum axles 9, which are arranged at a bottom end facing the bottom. As a result, a large clear space is formed below the undercarriage UW2, which is dimensioned so that it can be used as a passageway for the prevailing in a container terminal or quay traffic. The clear space of the gantry is in this case essentially formed by the distance between the two portal supports each other and their length between their bottom facing the bottom and its opposite upper end, to which each one of the adapter 6 and the central component 1 is connected.

The generator housing 8 in container form is now attached directly to the central component 1 via a support structure 20.

In addition to the turntable 2, the part-circular platform extensions 14 are attached and at one end of the adapter 6 with walkways 17, stairs 15 and ladder 16 configured for access, the walkway 17 at the height of the generator housing 8 between the component 1 and generator housing 8.

In the FIG. 3a a complete harbor crane is shown next to the undercarriage UW2 according to FIG. 3 includes a superstructure OW mounted thereon. In the FIG. 3 shown parts of the undercarriage UW2 are also in FIG. 3a shown and identified with the same reference numerals. The superstructure OW corresponds to the in FIG. 2a shown superstructure OW. The undercarriage UW2 has a portal chassis. It can be seen that between the portal supports, which are formed by the main side chassis supports 10 and the chassis, such a large clear space is formed that this can be used as a passageway for the prevailing in a container terminal or a quay traffic and accordingly underrun the Portal chassis or the undercarriage UW2 is possible.

FIG. 4 shows a mobile harbor crane undercarriage UW 3 in gantry design, but in contrast to FIG. 3 with rail bogies 11 on the main side chassis beams 10, which are now equipped without supports 12. Incidentally, the gantry undercarriage UW3 is formed in the same way as the gantry undercarriage of the undercarriage UW2, so that underwing is also possible here.

As an alternative energy supply, the mobile harbor crane undercarriage UW 3, as shown, with a foreign feed 21 and a downsized generator housing 8, which is also secured by means of a support structure 20 on the central component 1, are provided. This external power supply can be used both in a conventionally equipped crane and in the gantry design.

FIG. 5 shows a classic mobile harbor crane undercarriage UW 4, in which, in contrast to FIG. 2 a conventional tire chassis 22 has been installed. The tire chassis 22 is attached to the underside of the central component 1 via mounting brackets 23 which serve as adapters.

The mounting brackets 23 serve on the one hand for supporting the wishbone and on the other hand for supporting the axle suspensions and are welded to the central component 1 and fastened to the wishbone or axle suspension by means of bolts.
