Description

Die Erfindung betrifft einen Ladessystem zum Abdecken einer Schiffsluke oder ähnlichen Ladeöffnung während des Be- und Entladevorganges mittels eines an einem Lastaufnahmemittel, insbesondere Hafenmobilkran und Palettenlader, angeschlagenen Palettencontainers, wobei der auf dem Rand der Ladeöffnung aufsetzbare Ladeschacht selbstätig in Abhängigkeit von der Position des Palettencontainers geöffnet und geschlossen werden kann und dessen obere Schachtöffnung bei in dem Ladeschacht oder darunter befindlichen regengeschützten Palettencontainer durch einen oberhalb des Palettencontainers und des Lastaufnahmemittels angeordneten, sich auf dem Ladeschacht abstützenden, schirmartigen Schild abdeckbar ist, der einen freien Durchgang für die Seite des Hebezeuges aufweist und bei über die Höhe des Ladeschachtes angehobenem Lastaufmahmemittel auf diesem aufliegt.The invention relates to a charging system for covering a Ship hatch or similar loading opening during loading and Unloading process by means of a load suspension device, especially mobile harbor cranes and pallet loaders, battered Pallet containers, the one on the edge of the loading opening attachable loading slot automatically depending on the Position of the pallet container opened and closed can and its upper shaft opening at in the loading shaft or the rainproof pallet container below by one above the pallet container and the Load handler arranged, on the loading bay supporting, umbrella-like shield that can be covered has free passage for the side of the hoist and with the lifting device raised above the height of the loading shaft rests on this.

Eine gattungsgemäße Einrichtung zum Abdecken von Schiffsluken ist in der nicht vorveröffentlichten deutschen Patentanmeldung P 44 47 386.6 beschrieben und dient der witterungsunabhängigen Be- und Entladung von Schiffen, insbesondere mit palettierter Ladung. Beim Löschen von feuchtigkeitsempfindlichen Schiffsladungen bzw. beim Beladen von Schiffen mit solchen Gütern kommt es häufig zu wetterbedingten Verzögerungen und damit zu längeren Schiffsliegezeiten, die nicht nur den Transport der Waren verzögern, sondern auch infolge hoher zusätzlicher Liegegebühren, diese erheblich verteuern. Es ist deshalb verschiedentlich versucht worden, das Be- und Entladen auch bei schlechtem Wetter, insbesondere starkem Regen zu zu ermöglichen, indem das Wasser daran gehindert wurde, in den Stauraum einzudringen. Dies wurde beim gattungsbildenden Stand der Technik durch einen einseitig offenen Schacht gewährleistet, der über die Ladeöffnung des Schiffes gestülpt wird und auf deren Rand abgesetzt ein Gehäuse bildet, das an seiner oberen Seite durch übereinandergreifende Abdeckungen verschließbar ist. Durch die Palettencontainer oder an das Lastaufnahmemittel angehängte Körper kann die obere Abdeckung zeitweise für den Durchlaß der Hubseile beiseite gedrückt werden, ohne daß größere Wassermengen eindringen können. Der Ladeschacht selbst kann mit dem vorhandenen Kran aufgesetzt oder abgenommen werden und damit auf verschiedenen Schiffen verwendet werden, solange die Abmessungen des Ladeschachtes im wesentlichen den Abmessungen der Ladeöffnungen entsprechen.A generic device for covering ship hatches is in the unpublished German patent application P 44 47 386.6 describes and serves the weather-independent Loading and unloading of ships, especially with palletized ones Charge. When deleting moisture sensitive Shiploads or when loading ships with them Goods are often subject to weather-related delays and with longer ship lay times, which not only the Delay transportation of goods, but also due to high additional mooring fees, make them considerably more expensive. It is therefore various attempts have been made to load and unload even in bad weather, especially heavy rain allow by preventing the water from entering the storage space to penetrate. This was in the generic state of the art by a Guaranteed shaft open on one side, which slips over the loading opening of the ship is placed on the edge and forms a housing on its upper side can be closed by overlapping covers. Through the Pallet containers or bodies attached to the load handler can be the upper one Cover is temporarily pushed aside for the passage of the hoisting ropes without that larger amounts of water can penetrate. The loading slot itself can be used be put on or taken off the existing crane and thus on different ships can be used as long as the dimensions of the Loading slot essentially correspond to the dimensions of the loading openings.

Dadurch, daß die zweigeteilte übereinandergreifende Abdeckung der oberen Schachtöffnung mechanisch über Reibschluß durch die horizontale Bewegung des Lastaufnahmemittels und durch das Lastaufnahmemittel selbst geöffnet wird, besteht - insbesondere bei größerer Pendellänge der Hubseile - die Gefahr, daß sich die Palettencontainer schräg einstellt. Dies ist insbesondere beim Beladen von Schiffen dann von Nachteil, wenn der Beladevorgang automatisch erfolgt, weil infolge der ungewollten Schrägstellung der Palettencontainer ein geordnetes Beladen nicht mehr möglich ist.The fact that the two-part overlapping cover of the upper Manually opening the shaft mechanically via the horizontal movement of the Load handler and opened by the load handler itself, there is - especially with longer pendulum lengths of the hoisting ropes - the risk that the Pallet container is set at an angle. This is especially true when loading ships then disadvantageous if the loading process takes place automatically, because of the unintentional inclination of the pallet containers no longer ensures orderly loading is possible.

Aufgabe der vorliegenden Erfindung ist es deshalb, ausgehend von dem vorstehend beschriebenen bekannten Ladesystem, dieses so zu verbessern, daß unabhängig von der Bewegung des Lastaufnahmemittels die Position des Palettencontainers berührungslos erfaßt und davon abhängig das Öffnen und Schließen der Abdeckung gesteuert wird. Der Ladeschacht zum Abdecken der Ladeöffnung soll für eine Vielzahl unterschiedlicher Ladeöffnungsgrößen verwendet werden können, d. h. an die Ladeluken unterschiedlicher Schiffe anpaßbar sein. The object of the present invention is therefore, starting from the above described known charging system to improve this so that regardless of the position of the pallet container during the movement of the load handler detected without contact and depending on this the opening and closing of the cover is controlled. The loading slot to cover the loading opening is intended for a variety different loading opening sizes can be used, d. H. to the Loading hatches of different ships can be adapted.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, daß zum Öffnen und Schließen der Ladeöffnung im unteren Bereich des Ladeschachtes ein in seiner einen Endstellung die Ladeöffnung verschließendes Rolltor vorgesehen ist, wobei das geschlossene Rolltor bei in dem Ladeschacht befindlichem Palettencontainer unterhalb desselben angeordnet ist, daß das Rolltor nach Abdeckung der oberen Ladeschachtöffnung durch den Schild in eine die Ladeöffnung freigebende andere Endstellung verfahrbar ist, und daß die Öffnungs- und Schließbewegungen des Rolltores durch die Position des Palettencontainers erfassende berührungslose Geber steuerbar sind.To solve the problem, the invention proposes that to open and close the loading opening in the lower area the loading slot in its one end position the loading opening closing roller door is provided, the closed Roller door with pallet container located in the loading shaft is arranged below the same that the roller door after cover the upper loading slot opening through the sign into a die Other opening position releasing the loading opening is movable, and that the opening and closing movements of the roller shutter by non-contact detecting the position of the pallet container Are controllable.

Im Unterschied zu der bekannten Lösung wird das Öffnen und Schließen der Ladeöffnung nicht mehr durch das Lastaufnahmemittel bzw. den Palettencontainer selbst und mechanisch bewirkt, sondern berührungslos und unabhängig. Ein schräges Einstellen des Palettencontainers, auch bei größerer Pendellänge der Hubseile wird sicher ausgeschlossen, so daß ein störungsfreies Be- und Entladen möglich wird. Das Rolltor wird separat angetrieben verfahren und auf die der Position des Palettencontainers entsprechende Stellung eingestellt. Da das Rolltor mit dem oberhalb des Palettencontainers angeordneten schirmartigen Schild zusammenwirkt, kann nach Einfahren des Palettencontainers in den Ladeschacht das Öffnen des Rolltores so eingestellt werden, daß zunächst der Schild die obere Schachtöffnung weitgehend verschließt, bevor das Rolltor die Ladeöffnung freigibt. Auf diese Weise wird sichergestellt, daß stets die Ladeluke vor Witterungsbedingungen wie Schnee oder Regen geschützt bleibt und alle Vorgänge automatisierbar ablaufen können.In contrast to the known solution, the opening and The load suspension device no longer closes the loading opening or the pallet container itself and mechanically, but contactless and independent. An oblique adjustment of the Pallet containers, even with longer pendulum lengths of the lifting ropes is certainly excluded, so that a trouble-free loading and Unloading becomes possible. The roller door is driven separately move and to the position of the pallet container appropriate position set. Since the roller shutter with the umbrella-like arranged above the pallet container The shield cooperates after the pallet container has been driven in set the opening of the roller shutter in the loading shaft be that initially the shield largely the upper shaft opening closes before the roller door opens the loading opening. On this ensures that the loading hatch is always in front Weather conditions such as snow or rain remain protected and all processes can run automatically.

Vorzugsweise sind sämtliche Führungen für das Rolltor im Inneren des Ladeschachtes geführt, so daß der Ladeschacht mit Rolltor und Antrieb als Baueinheit - vom Kran transportiert - auf die Ladeöffnung des Schiffes aufgesetzt werden kann. All of the guides for the roller door are preferably inside out of the loading shaft, so that the loading shaft with roller shutter and drive as a structural unit - transported by crane the loading opening of the ship can be put on.

In einer Ausgestaltung der Erfindung ist vorgesehen, daß das umlenkfähig ausgebildete Rolltor beidseitig an endlos umlaufenden Zahnriemen geführt ist, die parallel zueinander an beiden Seiten im Inneren des Ladeschachtes über Umlenkrollen umlaufen, die das Rolltor, je nach Steuerung der Bewegungsrichtung der Zahnriemen, in die eine oder andere der Endstellungen verfahren. Der Bereich zwischen den endlos umlaufenden Zahnriemen bleibt frei, um die Ladung handhaben zu können.In one embodiment of the invention it is provided that roller door designed to be deflectable on both sides on endlessly rotating ones Toothed belt is guided, which are parallel to each other on both sides circulate inside the loading shaft via pulleys that the roller door, depending on the control of the direction of movement Timing belts in one or the other of the end positions. The area between the endless toothed belts remains free to handle the cargo.

Um sicherzustellen, den Ladeschacht auf eine möglichst große Zahl unterschiedlich großer Schiffe aufsetzen zu können, selbst dann, wenn die Ladeschachtbreite kleiner als die Breite der Ladeöffnung ist, wird nach einem anderen Merkmal der Erfindung vorgeschlagen, daß der Ladeschacht auf einem auf Breite und Höhe der Ladeöfnnung einstellbaren Untergestell angeordnet ist, das bei geringerer Ladeschachtbreite als Ladeöffnungsbreite die verbleibenden Öffnungsspalte abdeckt. Auf diese Weise können Rolltor und Schacht jeweils auf die Abmessungen des Palettencontainers abgestellt dimensioniert werden, während durch das verstellbare Untergestell die Anpassung an die veränderlichen Maße vor Ort vorgenommen wird. Dabei ist es insbesondere die Breite der Ladeöffnung, auf die Rücksicht zu nehmen ist, während die Länge der Ladeöffnungen in der Regel durch die am Schiff vorgesehenen Luken abgedeckt werden kann.To ensure the loading bay is as large as possible To be able to set up a number of different sized ships, even then when the loading slot width is smaller than the width of the Loading opening is according to another feature of the invention suggested that the loading bay on a width and Height of the loading opening adjustable base frame arranged is that with a smaller loading slot width than the loading opening width covers the remaining opening gaps. That way you can Roller shutter and shaft each to the dimensions of the Pallet containers are dimensioned while parked due to the adjustable base frame the adaptation to the variable dimensions is made on site. It is in particular the width of the loading opening, for consideration is to be taken while the length of the loading openings is usually can be covered by the hatches provided on the ship.

In einer Ausgestaltung ist vorgesehen, daß das Untergestell aus horizontalen, längenveränderbaren, an ihren freien Enden auf dem Rand der Ladeöffnung auflegbaren Stützträgern besteht, die mit einer beim Ausfahren der Stützträger abrollenden Schutzabdeckung (Rollo) für die Spalte zusammenwirken. Durch diese Lösung werden beim Anpassen der Stützträger auf die Breite der Ladeöffnung selbsttätig, in der Art einer Markise, Regenschutzabdeckungen abgerollt und über die verbleibende Ladeöffnung gezogen, so daß kein Wasser in die Ladeluke gelangen kann. Diese Lösung ist und funktionell und ermöglicht eine hohe Flexibilität des erfindungsgemäßen Ladeschachtes. In one embodiment it is provided that the underframe from horizontal, length-adjustable, at their free ends there are support straps that can be placed on the edge of the loading opening, which roll with one when the support beams extend Interact protective cover (roller blind) for the column. By this solution will be when adjusting the support beams to the width the loading opening automatically, in the manner of an awning, Rain covers unrolled and over the remaining Loading opening pulled so that no water can get into the loading hatch can. This solution is functional and enables one high flexibility of the loading slot according to the invention.

In einer Variante der Erfindung ist vorgesehen, daß für ein seitliches Einbringen des Palettencontainers in den Ladeschacht der Ladeschacht in der Draufsicht U-förmig mit einer offenen Seitenwand ausgebildet ist, die bei geöffneter Ladeöffnung durch das in seine zweite Endstellung verfahrene Rolltor verschließbar ist.
Häufig ist das Be- und Entladen des Schiffes vom Land durch seitliche Ansteuerung gewünscht. Das erfindungsgemäße Rolltor ist bei entsprechender seitlicher Führung in der Lage, auch für diesen Anwendungsfall die geeignete Schutzabdeckung darzustellen, indem die jeweils offene Seitenwand bei in den Schacht eingefahrener und nach oben durch den Schild abgedecktem Palettencontainer seitlich durch das Rolltor geschützt ist, wobei gleichtzeitig die untere Ladeöffnung zur Ladeluke freigegeben wird. Die Ladeöffnung ist also bei entsprechender Steuerung der Rolltorbewegung in jeder Stellung des Palettencontainers geschützt, ohne daß mechanische, mit dem Lastaufnahmemittel oder dem Palettencontainer gekoppelte Einrichtungen vorgesehen sein müssen.
In a variant of the invention it is provided that for a lateral introduction of the pallet container into the loading shaft of the loading shaft is U-shaped in plan view with an open side wall, which can be closed by the roller door moved into its second end position when the loading opening is open.
Loading and unloading of the ship from the shore by side control is often desired. The roll-up door according to the invention, with appropriate lateral guidance, is also able to provide the suitable protective cover for this application, in that the side wall which is open in each case is protected laterally by the roll-up door when the pallet container is inserted into the shaft and covered by the plate at the top, the lower one being simultaneously Loading opening to the hatch is released. The loading opening is thus protected with appropriate control of the roller shutter movement in every position of the pallet container, without mechanical devices coupled to the load handling device or the pallet container having to be provided.

Es ist in einer weiteren Variante auch denkbar, daß der Ladeschacht an seiner der offenen Seitenwand gegenüberliegenden Seite ebenfalls offen ist und diese Öffnung durch ein weiteres Rolltor verschließbar ist. Dieser Anwendungsfall ist denkbar, wenn zusätzlich ein Be- und Entladen von See- zu Binnenschiffen zu erfolgen hat.In a further variant, it is also conceivable that the loading shaft on its side opposite the open side wall is also open and this opening through another roller door is lockable. This use case is conceivable if additionally loading and unloading from sea to inland vessels has to be done.

Der Vorteil der vorliegenden Erfindung ist in der einfach und kostengünstig zu erstellenden Einrichtung zum Abdecken der Schiffsluke zu sehen, die nicht mehr hinsichtlich ihrer Öffnungs- oder Schließbewegung durch die Palettencontainer oder das Lastaufnahmemittel mechanisch gesteuert wird, sondern abhängig von der berührungslos erfaßten Posiiton des Palettencontainers im Ladeschacht. Das verstellbare Untergestell ermöglicht eine Anpassung des Ladeschachtes an unterschiedliche Ladeöffnungen und ist somit bei einer Vielzahl von Schiffen einsetzbar. Bei entsprechender Ausbildung ist das seitliche Ansteuern der Ladeöffnung ebenso möglich, wie das Durchladen durch den Ladeschacht zum Be- und Entladen von Seeschiffen zu Binnenschiffen.The advantage of the present invention is simple and inexpensive to create facility to cover the Ship hatch to see the no more regarding their Opening or closing movement through the pallet containers or the load suspension device is controlled mechanically, but depending on the non-contact position of the Pallet containers in the loading shaft. The adjustable base enables the loading slot to be adapted to different Loading openings and is therefore on a large number of ships applicable. With appropriate training, this is the side Controlling the loading opening is just as possible as loading through the loading shaft for loading and unloading of seagoing vessels to barges.

In Figur 1 ist grob schematisch ein Querschnitt durch ein zu entladendes Schiff 1 dargestellt, dessen Laderaum 3 nach oben (Ladeöffnung 2) offen ist, so daß der regengeschützte Palettencontainer 4 mittels Laufkatze 5a und Lastaufnahmemittel 5b in die Ladeluke 3 transportiert werden kann. Als Schutz vor Witterungseinflüssen wird die Ladeöffnung 2 des Schiffskörpers durch den Ladeschacht 6 verschlossen, der mit nach außen geneigten Seitenwänden auf dem Untergestell 7 angeordnet ist, das aus den horizontal längenveränderbaren Stützträgern 8 besteht, die an ihren freien Enden 9 mit vertikal höhenveränderbaren Stützen 10a und Stützplatten 10b auf dem Rand 11 der Ladeöffnung aufliegen. Zwischen den Stützträgern 8 ist eine Schutzabdeckung 12 vorgesehen, die beidseitig des Ladeschachtes 6 den bei 13 verbleibenden Öffnungsschacht abdeckt. Die Schutzabdeckung ist in der Art eines Rollos bei 15 aufgerollt und bei 15 im Bereich des Ladeschachtes befestigt, so daß die Schutzabdeckung 12 sich beim Ausfahren der Stützträger 8 sebsttätig abrollt und den Öffnungsspalt verschließt.In Figure 1 is a schematic cross section through a unloading ship 1 shown, the cargo hold 3 upwards (Loading opening 2) is open, so that the rain-protected Pallet container 4 by means of trolley 5a and load handling device 5b can be transported into the loading hatch 3. For protection the loading opening 2 of the hull becomes exposed to the weather closed by the loading shaft 6, which is inclined to the outside Side walls is arranged on the base 7, which consists of the horizontally adjustable support beams 8, the vertically variable at their free ends 9 Supports 10a and support plates 10b on the edge 11 of the loading opening lie on. Between the support beams 8 is a protective cover 12 provided on both sides of the loading shaft 6 at 13 remaining opening shaft covers. The protective cover is rolled up like a roller blind at 15 and at 15 in Area of the charging bay attached so that the protective cover 12 unrolls itself automatically when the support beams 8 extend and closes the opening gap.

Der Palettencontainer 4 ist an den Seilen 16 heb- und senkbar am Lastaufnahmemittel angeschlagen, wobei sich zwischen Laufkatze 5a und Lastaufnahmemittel 5b ein Schild 18, durch Seile 16 geführt, vertikal frei bewegt, das in seiner horizontalen Erstreckung die obere Schachtöffnung überdeckt, wenn der Palettencontainer im Ladeschacht 6 oder darunter ist. Der Schild 18 verschließt beim Laden des Palettencontainers 4 den Ladeschacht nach oben.The pallet container 4 can be raised and lowered on the ropes 16 attached to the load handler, whereby between trolley 5a and load suspension means 5b a sign 18, by ropes 16 guided, freely moving vertically, in its horizontal Extension covers the upper shaft opening when the pallet container is in the Loading slot 6 or below. The shield 18 closes when loading the Pallet containers 4 up the loading shaft.

Wie in Figur 2 besser zu sehen, ist der Ladeschacht 6 mit längenveränderbaren Abspannseilen 19 am Schiffskörper 1 fixiert. Der Schacht weist im Inneren einen Ringbund 20 auf, auf den der Schild 18 auflegbar ist, unter dem die obere Umlenkrolle 21 von zwei weiteren Umlenkrollen 22 und 23 angeordnet ist, um die endlos geführte Zahnriemen 24 parallel zueinander an beiden Seiten des Ladeschachtes 6 umlaufen. Die Zahnriemen 24 führen zwischen sich das umlenkfähige Rolltor 25, das in der in Figur 2 dargestellten Stellung die Ladeöffnung 2 des Schiffskörpers 1 verschließt. Durch die schräge Führung des Rolltores 25 kann das durch die obere Schachtöffnung eindringende Regenwasser seitlich ablaufen und abgeführt werden. Die Ladeöffnung 2 ist also in der dargestellten Position durch das Rolltor 25 sowie die Schutzabdeckungen 12 verschlossen.As can be seen better in FIG. 2, the loading shaft 6 is variable in length Guy ropes 19 fixed to the hull 1. The shaft has one inside Ring collar 20 on which the shield 18 can be placed, under which the upper pulley 21 of two further deflection rollers 22 and 23 is arranged around the endlessly guided Toothed belt 24 run parallel to each other on both sides of the loading shaft 6. The toothed belt 24 lead between them the deflectable roller shutter 25, which in the Figure 2 shown position closes the loading opening 2 of the hull 1. Due to the inclined guidance of the roller shutter 25, this can be done through the upper shaft opening ingress of rainwater from the side and be drained off. The loading opening 2 is in the position shown by the roller shutter 25 and the Protective covers 12 closed.

Wie in Figur 2 weiterhin erkennbar, sind im Inneren des Ladeschachtes 6 verschiedene mit a, b und c bezeichnete Geber angeordnet, die die Position der in den Ladeschacht transportierten Palettencontainer 4 erfassen und zur Steuerung des Rolltores 25 verwendet.As can also be seen in FIG. 2, there are 6 in the interior of the loading shaft Various sensors labeled a, b and c are arranged, which correspond to the position of the sensors Load shaft transported pallet container 4 capture and to control the Roller doors 25 used.

In der Zeichnungsfigur 3 ist in sechs Schritten der Beladevorgang des Laderaums 3 dargestellt. Im ersten Schritt transportieren Laufkatze 5a und Lastaufnahmemittel 5b den Palettencontainer 4 in Pfeilrichtung 26. Das Rolltor 25 steht in seiner Endstellung und verschließt zusammen mit den Schutzabdeckungen 12 (Figur 2) die Ladeöffnung 2. Die Seitenwände des Ladeschachtes 6 bilden ein geschlossenes Gehäuse; das durch die obere Schachtöffnung eindringende Wasser läuft über das geschlossene Rolltor 25 seitlich ab.In the drawing figure 3 is the loading process of the loading space 3 in six steps shown. In the first step, trolley 5a and load handling device 5b are transported the pallet container 4 in the direction of the arrow 26. The roller door 25 is in its end position and closes the loading opening together with the protective covers 12 (FIG. 2) 2. The side walls of the loading shaft 6 form a closed housing; the Water entering through the upper shaft opening runs over the closed one Roller door 25 from the side.

In der zweiten dargestellten Phase hat der Palettencontainer 4 eine Position oberhalb des Ladeschachtes 6 erreicht; die Stellung des Rolltores ist unverändert.In the second phase shown, the pallet container 4 has a position above the loading slot 6 reached; the position of the roller shutter is unchanged.

In der dritten dargestellten Phase ist durch Nachlassen der Hubseile 16 der Palettencontainer 4 in den Ladeschacht 6 eingetaucht und hat die ersten Positionsgeber a erreicht. Bei weiterem Absenken des Palettencontainers beginnt sich das Rolltor 25 bei umlaufenden Zahnriemen 24 zu öffnen, während gleichzeitig der Schild 18 die obere Schachtöffnung zu verschließen beginnt. Dieser Vorschlag ist in Phase vier dargestellt.In the third phase shown, the lifting cables 16 cause the Pallet container 4 immersed in the loading shaft 6 and has the first Position encoder a reached. If the pallet container is lowered further, it begins to open the roller door 25 with rotating toothed belt 24, while the Shield 18 begins to close the upper shaft opening. This suggestion is in Phase four shown.

In Phase 5 wurde der Palettencontainer weiter abgesenkt, der Schild 18 liegt auf dem Ringbund 20 des Ladeschachtes 6 auf und verschließt diesen dicht. Gleichzeitig ist das Rolltor 25 in eine Position seitlich des Ladeschachtes 6 gefahren, wie sie vergrößert in Figur 1 erkennbar ist. Die Ladeöffnung 2 ist freigegeben, so daß der Palettencontainer 4 in den Laderaum 3 eintauchen kann. Alle Öffnungen sind verschlossen, und zwar durch den Schild 18, die Schutzabdeckungen 12 beidseitig des Ladeschachtes 6 und durch die Wände des Ladeschachtes 6 selbst. Diese Stellung wird beibehalten, bis der Palettencontainer 4 (sechste Phase) den Boden der Ladeluke 3 erreicht hat und dort mittels Gabelstapler be- oder entladen wurde.In phase 5, the pallet container was lowered further, the sign 18 is on the Ring collar 20 of the loading shaft 6 and closes it tightly. At the same time the roller door 25 moved into a position to the side of the loading shaft 6, as they enlarged in Figure 1 can be seen. The loading opening 2 is released so that the Pallet container 4 can be immersed in the loading space 3. All openings are closed, namely by the shield 18, the protective covers 12 on both sides of the loading shaft 6 and through the walls of the loading shaft 6 itself. This The position is maintained until the pallet container 4 (sixth phase) hits the bottom of the Has reached hatch 3 and was loaded or unloaded there by forklift.

Beim Entfernen des Palettencontainers aus der Ladeluke verlaufen die Schritte in umgekehrter Richtung, wobei die Ladeöffnung 2 des Schiffskörpers 1 in jeder Stellung so verschlossen ist, daß Witterungseinflüsse die Ladung nicht beschädigen können.When removing the pallet container from the loading hatch, the steps in reverse direction, the loading opening 2 of the hull 1 in any position is locked so that weather conditions cannot damage the cargo.
