Zur Positionierung des Spreaders und damit eines an diesem verriegelten Containers hat der Portalhubwagen eine Positioniervorrichtung, mittels der der Spreader innerhalb des Rahmengestells und in Bezug auf das Rahmengestell in seiner Horizontalebene beliebig positionierbar ist.One from the US 4,432,690 A known straddle carrier has a frame and a spreader, which hangs between the frame and can be locked with a container. On the underside of the frame carriage are provided, each having a plurality of arranged in a row wheels. For vertical movement of the spreader a lifting device is provided from lifting cylinders, by means of which the spreader can be raised and lowered via hoisting ropes, which are mounted with one side directly on the spreader. To position the spreader and thus a container locked on this, the straddle carrier has a Positioning device by means of which the spreader is freely positionable within the frame and in relation to the frame in its horizontal plane.

Die GB 2 029 374 A zeigt eine verfahrbare Umschlageinrichtung, die Bestandteil bzw. über Verbindungsmittel fest mit einer Krananlage verbunden ist und dazu dient, von ihr aufgenommene Container auf LKW od.dgl. zu verladen.The GB 2 029 374 A shows a movable handling device, the component or via connecting means is firmly connected to a crane system and serves to recorded by her container on trucks or the like. to load.

Die US 3,874,719 A zeigt eine Spreaderanlage, bei der die Hubeinrichtung mittels Hydraulikzylindern realisiert ist. Die die im Falle der Spreaderanlage zur Positionierung des Spreaders innerhalb des Rahmengestells dienenden Hydraulikzylinder sind zwischen zueinander verstellbaren spreaderseitigen Bauteilen angeordnet.The US 3,874,719 A shows a spreader, in which the lifting device is realized by means of hydraulic cylinders. The serving in the case of Spreaderanlage for positioning the spreader within the frame hydraulic cylinders are arranged between mutually adjustable spreaderseitigen components.

Die DE 3336458 A1 und die DE 202004018066 U1 zeigen Hubvorrichtungen, bei denen mehrere Hubwinden vorgesehen sind.The DE 3336458 A1 and the DE 202004018066 U1 show lifting devices in which several hoisting winches are provided.

Aus der JP 2005 067 832 A ist ein Portalhubwagen zum Einsatz in Containerterminals und für allgemeine Transportaufgaben mit den im Oberbegriff der nebengeordneten Patentansprüche 1 und 2 angegebenen Merkmalen bekannt.From the JP 2005 067 832 A is a straddle carrier for use in container terminals and general transport tasks with the features specified in the preamble of the independent claims 1 and 2 known.

Ausgehend von dem vorstehend geschilderten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, den konstruktivtechnischen Aufbau eines Portalhubwagens zu vereinfachen, seine Tragfähigkeit zu erhöhen und die Möglichkeiten zur Positionierung des Spreaders mit oder ohne an ihm verriegeltem Container zu verbessern, wobei aufwändige Fahrmanöver des Portalhubwagens in den Containergassen von Containerterminals zur Feinpositionierung des Spreaders bzw. des mit dem Spreader verriegelten Containers minimier- oder möglichst ganz vermeidbar sein sollen, wobei durch entsprechende separate Beaufschlagung der Verstellglieder in exakt dosierter Weise die Position des Spreaders innerhalb des Rahmengestells fein justierbar sein soll und wobei die Verstellglieder gegen Beschädigungen durch von derartigen Bauteilen schlecht oder nicht aufnehmbaren Querkräften geschützt sein sollen.Based on the above-described prior art, the present invention seeks to simplify the structural design of a gantry, to increase its carrying capacity and to improve the possibilities for positioning the spreader with or without it locked container, with elaborate driving maneuver of the gantry in the container lanes of container terminals for fine positioning of the spreader or with the spreader locked containers should be minimized or avoided as completely as possible, with the position of the spreader within the rack to be finely adjusted by appropriate separate loading of the adjusting in a precisely metered manner and the adjusting be protected against damage by such components poor or not absorbable shear forces should.

Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst. Aufgrund der Mehrzahl von Hubwinden ist die Tragfähigkeit des Portalhubwagens beträchtlich erhöht. Durch die geschaffene Verstellmöglichkeit des Spreaders sowohl in X- als auch in Y-Richtung seiner Horizontalebene ist es möglich, den Spreader ohne den Portalhubwagen zu verfahren und exakt in derjenigen Stellung zu positionieren, in der er in einfacher Weise mit einem Container verriegelbar ist, bzw. in der ein am Spreader verriegelter Container vom Spreader gelöst werden soll. Die Verstellglieder der Positioniervorrichtung sind als Fluid-, vorzugsweise als Hydraulikzylinder ausgebildet, die mittels eines Gelenks gelenkig mit jeweils einem Eckbereich des Spreaders und mittels eines Gleitgelenks gelenkig und gleitend verschieblich mit der diesem Eckbereich des Spreaders zugeordneten bzw. nächsten vertikalen Stütze des Rahmengestells verbunden sind.This object is achieved by the features stated in the characterizing part of patent claim 1. Due to the majority of hoisting winches, the carrying capacity of the straddle carrier is considerably increased. The created adjustment of the spreader both in the X and in the Y direction of its horizontal plane, it is possible to move the spreader without the straddle carrier and position exactly in that position in which it can be locked in a simple manner with a container, or in which a container locked on the spreader is to be detached from the spreader. The adjusting members of the positioning device are designed as fluid, preferably as hydraulic cylinders which are articulated by means of a joint with a respective corner region of the spreader and by means of a sliding joint and slidably connected to this corner region of the spreader associated or next vertical support of the frame.

Zum Schutz der Fluid- bzw. Hydraulikzylinder gegen Querkräfte, die durch derartige Bauteile schlecht oder nicht aufnehmbar sind, ist jedem Fluid- bzw. Hydraulikzylinder der Positioniervorrichtung eine Teleskopeinrichtung zugeordnet, mittels der auf den Fluid- bzw. Hydraulikzylinder einwirkende Querkräfte aufnehm- und ableitbar sind, wobei alternativ vorgesehen ist, jedem Fluid- bzw. Hydraulikzylinder der Positioniervorrichtung eine Knickarmeinrichtung zuzuordnen, die ebenfalls dazu dient, auf den Fluid- bzw. Hydraulikzylinder einwirkende Querkräfte aufzunehmen und abzuleiten.To protect the fluid or hydraulic cylinder against transverse forces, which are poor or not absorbable by such components, each fluid or hydraulic cylinder of the positioning device is associated with a telescopic device, by means of acting on the fluid or hydraulic cylinder transverse forces are absorbed and derivable , where provided alternatively is to associate with each fluid or hydraulic cylinder of the positioning a Knickarmeinrichtung, which also serves to absorb and dissipate acting on the fluid or hydraulic cylinder transverse forces.

Je nach vertikaler Position des Spreaders in Bezug auf das Rahmengestell wandern die Verstellglieder an den ihnen zugeordneten vertikalen Stützen des Rahmengestells und können so in jeder Vertikalstellung des Spreaders zur Feinpositionierung desselben verwendet werden.Depending on the vertical position of the spreader with respect to the frame, the adjusting members move on their associated vertical supports of the frame and can be used in each vertical position of the spreader for fine positioning thereof.

Zweckmäßigerweise können den spreaderseitigen Hubseilaufhängepunkten zugeordnete Seilenden der Hubseile unmittelbar bzw. direkt am Spreader angebracht sein.Appropriately, the spreaderseitigen Hubseilaufhängepunkten associated cable ends of the hoisting ropes may be attached directly or directly to the spreader.

Gemäß einer vorteilhaften Ausführungsform des erfindungsgemäßen Portalhubwagens sind die spreaderseitigen Hubseilaufhängepunkte als Umlenkrollen ausgebildet. Durch Auf- bzw. Abrollen der Hubseile mittels der Hubwinden, an denen die Hubseile beidendig angebracht sind, kann die vertikale Beweglichkeit des Spreaders und ggf. des damit verriegelten Containers in schonender Weise bewerkstelligt werden, so dass Container mit einem vergleichsweise geringen Aufwand transportabel und positionier- bzw. stapelbar sind.According to an advantageous embodiment of the gantry invention, the spreaderseitigen Hubseilaufhängepunkte are designed as deflection rollers. By winding or unwinding the hoisting ropes on which the hoisting ropes are attached at both ends, the vertical mobility of the spreader and possibly the container locked therewith can be accomplished in a gentle manner, so that containers can be transported and positioned with a comparatively low outlay or stackable.

Vorteilhaft ist an jedem der vier Eckbereiche des Spreaders ein Hubseilaufhängepunkt bzw. eine Umlenkrolle angeordnet, so dass die Bewegungen des Spreaders sowie des ggf. an dem Spreader verriegelten Containers gut kontrollier- bzw. einschränkbar sind.Advantageously, a Hubseilaufhängepunkt or a guide roller is arranged at each of the four corner regions of the spreader, so that the movements of the spreader and optionally locked to the spreader container are well controlled or limited.

Alternativ kann es zweckmäßig und günstig sein, nur drei Eckbereiche des Spreaders mit einem entsprechenden Verstellglied zu versehen; hierdurch können insbesondere die Sichtmöglichkeiten der Bedienungsperson des Portalhubwagens verbessert werden.Alternatively, it may be expedient and advantageous to provide only three corner regions of the spreader with a corresponding adjusting member; As a result, in particular the visibility of the operator of the straddle carrier can be improved.

Gemäß einer vorteilhaften Ausführungsform des erfindungsgemäßen Portalhubwagens können die Verstellglieder als Elektrozylinder oder Elektrolinearantrieb ausgebildet sein.According to an advantageous embodiment of the portal lifting carriage according to the invention, the adjusting members may be designed as electric cylinders or electric linear drive.

Es ist auch möglich, die Verstellglieder bei einem entsprechenden Anforderungsprofil als pneumatische Zylinder auszugestalten.It is also possible to design the adjusting members with a corresponding requirement profile as a pneumatic cylinder.

Eine weitere Funktionalität der Positioniervorrichtung ergibt sich, wenn an den Fluid- bzw. Hydraulikzylindern oder pneumatischen Zylindern derselben ein Grenzdruck einstellbar ist, bei dessen Erreichen bzw. Überschreiten die Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder abblasen. Hierdurch kann die Positioniervorrichtung zugleich der Stoßabsorption dienen, indem durch entsprechende Einstellung des Grenzdrucks sichergestellt wird, dass die Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder abblasen, falls es zu einem Zusammenstoß beispielsweise des am Spreader verriegelten Containers mit einem Hindernis kommt.A further functionality of the positioning device is obtained when a limiting pressure is adjustable on the fluid or hydraulic cylinders or pneumatic cylinders thereof, at the reaching or exceeding of which the fluid or hydraulic cylinders or pneumatic cylinders blow off. In this way, the positioning device can also serve the shock absorption by ensuring by appropriate adjustment of the limit pressure that blow off the fluid or hydraulic cylinder or pneumatic cylinder, if it comes to a collision, for example, of the spreader locked container with an obstacle.

Selbstverständlich ist es auch möglich, je nach Anforderungsprofil für einen oder mehrere Fluid- bzw. Hydraulikzylinder oder pneumatische Zylinder Teleskopeinrichtungen und für den bzw. die anderen Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder Knickarmeinrichtungen vorzusehen.Of course, it is also possible, depending on the requirement profile for one or more fluid or hydraulic cylinder or pneumatic cylinder telescopic devices and provide for the or the other fluid or hydraulic cylinder or pneumatic cylinder articulated arm.

Im Folgenden wird die Erfindung anhand von Ausführungsformen unter Bezugnahme auf die Zeichnung näher erläutert.In the following the invention will be explained in more detail by means of embodiments with reference to the drawing.

Jeder Hydraulikzylinder 20, 21, 22, 23 ist an einem Ende durch ein Gelenk 24 mit dem Spreader 6 verbunden, wobei die Anordnung des Gelenks 24 nahe den Eckbereichen 15, 16, 17 bzw. 18 vorgesehen ist.Each hydraulic cylinder 20, 21, 22, 23 is connected at one end by a hinge 24 to the spreader 6, wherein the arrangement of the joint 24 is provided near the corner regions 15, 16, 17 and 18, respectively.

Mit seinem anderen Ende ist jeder Hydraulikzylinder 20, 21, 22, 23 über ein Gleitgelenk 25 mit derjenigen vertikalen Stütze 4 des Rahmengestells 2 des Portalhubwagens 1 verbunden, die dem jeweiligen Eckbereich 15, 16, 17 bzw. 18 des Spreaders 6 gegenüberliegt bzw. zunächst angeordnet ist. Die Gleitgelenke 25 bewegen sich mit den Vertikalbewegungen des Spreaders 6 auf- und abwärts an den ihnen jeweils zugeordneten vertikalen Stützen 4, da sie dort in Vertikalrichtung gleitend verschieblich angebracht sind.At the other end, each hydraulic cylinder 20, 21, 22, 23 is connected via a slide joint 25 to that vertical support 4 of the frame 2 of the gantry truck 1, which faces the respective corner region 15, 16, 17 or 18 of the spreader 6 or first is arranged. The sliding joints 25 move with the vertical movements of the spreader 6 up and down to their respective associated vertical supports 4, since they are slidably mounted there in the vertical direction.

Aufgrund der Hydraulikzylinder 20, 21, 22, 23, die jeweils beliebig mit Hydraulikflüssigkeit beaufschlagbar sind, kann der Spreader 6 in Bezug auf das Rahmengestell 2 und damit in Bezug auf den Portalhubwagen 1 quasi beliebig sowohl in Fahrtrichtung des Portalhubwagens 1 als auch in der dazu senkrechten Querrichtung positioniert werden; der Portalhubwagen 1 muss für diese Feinpositionierung des Spreaders 6, die in beiden Richtungen einer Horizontalebene erfolgen kann, nicht bewegt werden. Hierdurch lassen sich aufwändige Fahrmanöver des Portalhubwagens 1 bei der Feinpositionierung des Spreaders 6 oberhalb eines Containers 8 bzw. bei der Feinpositionierung eines am Spreader 6 hängenden Containers 8 vermeiden.Due to the hydraulic cylinder 20, 21, 22, 23, each of which can be acted upon with hydraulic fluid, the spreader 6 with respect to the frame 2 and thus with respect to the straddle carrier 1 almost arbitrarily both in the direction of travel of the gantry truck 1 and in the be positioned perpendicular transverse direction; the straddle carrier 1 must not be moved for this fine positioning of the spreader 6, which can be done in both directions of a horizontal plane. This makes it possible to avoid expensive driving maneuvers of the straddle carrier 1 during the fine positioning of the spreader 6 above a container 8 or during the fine positioning of a container 8 suspended on the spreader 6.

Die quasi beliebige Positionierbarkeit des Spreaders 6 innerhalb des Rahmengestells 2 geht am besten aus den Figuren 4 und 5 hervor.The virtually arbitrary positionability of the spreader 6 within the frame 2 is best from the FIGS. 4 and 5 out.

In den gezeigten Ausführungsbeispielen ist an den Hydraulikzylindern 20, 21, 22, 23 der Positioniervorrichtung ein Grenzdruck einstellbar, bei dessen Erreichen bzw. Überschreiten die Hydraulikzylinder 20, 21, 22, 23 Hydraulikfluid abblasen. Hierdurch kann sichergestellt werden, dass es bei einem Zusammenstoß eines Containers 8 mit einem Hindernis zu einer zumindest teilweisen Stoßabsorption kommt. Irgendwelche Beschädigungen etc. des Containers 8 bzw. des Portalhubwagens oder desjenigen Gegenstands, gegen den der Container 8 stößt, lassen sich hierdurch - wenn nicht vermeiden - so doch erheblich reduzieren.In the embodiments shown, a limit pressure is adjustable on the hydraulic cylinders 20, 21, 22, 23 of the positioning device, upon reaching or exceeding of which the hydraulic cylinders 20, 21, 22, 23 blow off hydraulic fluid. In this way it can be ensured that, in the event of a collision of a container 8 with an obstacle, an at least partial impact absorption occurs. Any damage, etc., of the container 8 or of the straddle carrier or of that object against which the container 8 abuts can thereby be considerably reduced if not avoided.

Die Hydraulikzylinder 20, 21, 22, 23 sind üblicherweise mit dem freien Ende ihres Hubglieds 26 mit dem stützenseitigen Gleitgelenk 25 verbunden; grundsätzlich ist es auch möglich, wie dies in Figur 5 am dort rechten unteren Eckbereich 18 beispielhaft gezeigt ist, dass der Hydraulikzylinder 23 mit seinem Hubglied 26 an dem spreaderseitigen Gelenk 24 sitzt.The hydraulic cylinders 20, 21, 22, 23 are usually connected to the free end of their lifting member 26 with the support-side slide joint 25; In principle, it is also possible, as in FIG. 5 is shown there by way of example at the bottom right corner area 18, that the hydraulic cylinder 23 is seated with its lifting member 26 on the spreaderseitigen joint 24.

Zum Schutz der Hydraulikzylinder 20, 21, 22, 23 gegen mittels dieser kaum bzw. nicht aufnehmbaren Querkräften können die Hydraulikzylinder, wie dies in Figur 4 gezeigt ist, mit jeweils einer Teleskopeinrichtung 27 versehen sein. Die Teleskopeinrichtung 27 umhüllt den ihr zugeordneten Hydraulikzylinder 20, 21, 22 bzw. 23 quasi formschlüssig, und zwar insbesondere und in jedem Fall in demjenigen Bereich des Hydraulikzylinders 20, 21, 22, 23, in dem das Hubglied 26 desselben austritt. Hierdurch kann ein Abknicken oder eine ähnliche Beschädigung des Hydraulikzylinders 20, 21, 22, 23 zuverlässig vermieden werden.To protect the hydraulic cylinders 20, 21, 22, 23 against this by means of these hardly or not absorbable lateral forces, the hydraulic cylinder, as shown in FIG. 4 is shown, each with a telescopic device 27 may be provided. The telescopic device 27 encloses its associated hydraulic cylinder 20, 21, 22 and 23 virtually positively, in particular and in each case in that area of the hydraulic cylinder 20, 21, 22, 23, in which the lifting member 26 thereof exits. In this way, a kinking or similar damage of the hydraulic cylinder 20, 21, 22, 23 can be reliably avoided.

Mittels der Teleskopeinrichtungen 27 sind die auf die Hydraulikzylinder 20, 21, 22, 23 beim Betrieb des Portalhubwagens 1 bzw. des Spreaders 6 in Querrichtung auftretenden Kräfte aufnehm- und ableitbar.By means of the telescopic devices 27, the forces acting on the hydraulic cylinders 20, 21, 22, 23 during operation of the gantry carriage 1 and of the spreader 6 in the transverse direction can be absorbed and discharged.

Anstelle der Teleskopeinrichtungen 27 sind im Falle des in Figur 5 gezeigten Ausführungsbeispiels des Spreaders 6 Knickarmeinrichtungen 28 vorgesehen, von denen jeweils eine jedem Hydraulikzylinder 20, 21, 22, 23 zugeordnet ist. Auch mittels dieser Knickarmeinrichtungen 28 lassen sich in Querrichtung der Hydraulikzylinder 20, 21, 22, 23 auf diese einwirkende Kräfte aufnehmen und ableiten.Instead of the telescopic devices 27 are in the case of in FIG. 5 shown embodiment of the spreader 6 Knickarmeinrichtungen 28 are provided, each of which is assigned to each hydraulic cylinder 20, 21, 22, 23. Also by means of these Knickarmeinrichtungen 28 can be in the transverse direction of the hydraulic cylinder 20, 21, 22, 23 absorb and dissipate acting on these forces.
