Description

Die Erfindung betrifft einen Hafenkran, insbesondere Hafenmobilkran für Normal- und Schwertastbetrieb, mit einem Unterwagen und einem auf dem Unterwagen angebrachten vorzugsweise drehbaren Oberwagen, einem auf dem Oberwagen befestigten Turm, an dem ein um eine horizontale Achse verschwenkbarer Ausleger angeordnet ist, wobei der Ausleger im Normalbatrieb mittels eines am Ausleger und am Turm angelenkten Wippzylinders schwenkbar am Oberwagen gehalten ist und die Last mittels eines zum Auslegerkopf geführten Hubseiles mit daran angehängter Hakenflasche aufnehmbar ist.The invention relates to a harbor crane, in particular harbor mobile crane for normal and Heavy duty operation, with one undercarriage and one on the undercarriage attached preferably rotatable superstructure, one on the superstructure fortified tower, on which a boom pivotable about a horizontal axis is arranged, the boom in the normal battery drive by means of a boom and on the tower articulated luffing cylinder is pivotally held on the superstructure and the Load by means of a hoist rope to the boom head with attached Hook bottle is recordable.

Hafenmobilkrane der gattungsgemäßen Art sind häufig auch zum Einsatz im Schwerlastbetrieb konzipiert. Dazu sind die entsprechenden notwendigen konstruktiven Maßnahmen für diese Schwerlastfälle vorgesehen, z.B. stärkere umschaltbare Hubwerke, stärkere Seile und dem Schwerlastfall angepaßte Klassifizierung. Je nach Gerätegröße ist man in der Lage, mit normalen Hafenmobilkranen Schwerlasten bis zu 120 t umzuschlagen; das Verhältnis Normallast zu Schwertast beträgt ca. 1:2.Mobile harbor cranes of the generic type are often also used in Heavy duty operation designed. The corresponding are necessary for this constructive measures for these heavy load cases, e.g. stronger switchable hoists, stronger ropes and adapted to the heavy load case Classification. Depending on the size of the device, you are able to use normal ones Mobile cranes handling heavy loads of up to 120 t; The relationship Normal load to heavy duty is approx. 1: 2.

Besteht ein Bedarf für den Umschlag von noch größeren Lasten, so werden beispielsweise zwei Hafenmobilkrane im Tandembetrieb eingesetzt. Ein solcher Betrieb ist stets mit einer sorgfältigen Planung und Vorbereitung und mit einer zeitaufwendigen Durchführung verbunden, weil die Koordination der Geräte nicht ohne Risiken ist. Eine andere Möglichkeit für den Hafenbetreiber besteht darin, einen Schwimm- oder Automobilkran mit entsprechend hoher Tragfähigkeit einzusetzen. Das verteuert jedoch den Lastumschlag erheblich und man ist von der Verfügbarkeit der anzumietenden Krane abhängig. If there is a need for the handling of even larger loads, then For example, two mobile harbor cranes used in tandem. Such a Operation is always with careful planning and preparation and with one time-consuming implementation because the coordination of the devices does not is without risks. Another option for the port operator is one Use floating or automobile cranes with a correspondingly high load capacity. However, this increases the cost of cargo handling considerably and one is dependent on availability depends on the cranes to be rented.

Aufgabe der vorliegenden Erfindung ist es, einen konventionellen Hafenkran, insbesondere Hafenmobilkran durch Zusatzeinrichtungen so umzurüsten, daß er mit vertretbaren konstruktiven Maßnahmen und mit kurzen Rüstzeiten sowohl im Normalbetrieb wie auch im Schwerlastbetrieb eingesetzt werden kann.The object of the present invention is to provide a conventional harbor crane, in particular to convert mobile harbor cranes by additional equipment so that it can be used reasonable constructive measures and with short set-up times both in Normal operation as well as in heavy-duty operation can be used.

Zur Lösung der Aufgabe wird erfindungsgemäß ein Hafenkran vorgeschlagen, der folgende Merkmale aufweist:

  • am Oberwagen des Hafenkrans ist vorzugsweise unterhalb des Auslegers eine Schwerlast-Hubwinde zusätzlich fest angeordnet, von der ein über eine am Ausleger befestigte Umlenkrolle lenkbares Schwerlast-Hubseil zu dem Rollensatz einer am Auslegerkopf lösbar angeordneten Schwerlast-Hakenflasche geführt ist,
  • das Normallast-Hubwerk des Hafenkranes ist im Schwerlastbetrieb als Wippwerk für den Ausleger einsetzbar, wozu die Normallast-Hubseile von der Normallast-Hakenflasche gelöst und am Auslegerkopf angeschlagen werden,
  • der freigeschaltete Wippzylinder dient als Rückfallstütze für den Ausleger,
  • das Standmoment des Hafenmobilkranes wird gegenüber dem Normallast-Betrieb erhöht.
    • To solve the problem, a harbor crane is proposed according to the invention, which has the following features:
  • On the superstructure of the harbor crane, a heavy-duty hoist winch is preferably additionally arranged underneath the jib, from which a heavy-duty hoist rope that can be steered via a deflection roller attached to the jib is guided to the roller set of a heavy-duty hook block that is detachably arranged on the jib head,
  • the normal load hoist of the harbor crane can be used as a luffing mechanism for the jib in heavy load operation, for which purpose the normal load hoisting ropes are detached from the normal load hook block and attached to the jib head,
  • the released luffing cylinder serves as a fall support for the boom,
  • the stationary torque of the mobile harbor crane is increased compared to normal load operation.

    • Die durch den Einsatz der Schwerlasteinrichtung stärker beanspruchten Bauteile, wie z.B. Ausleger, Turm, Drehverbindung und Kranabstützung, und deren Anschlußkonstruktionen werden bei Bedarf, d.h. nur bei entsprechender Traglaststeigerung, verstärkt.The components that are more stressed by the use of the heavy-duty device, such as e.g. Boom, tower, slewing ring and crane support, and their Connection structures are made if necessary, i.e. only if appropriate Load increase, reinforced.

    Mit einem Hafenkran der vorgeschlagenen Art werden die vorstehend beschriebenen Nachteile vermieden. Dabei werden Funktion und Basiskonstruktion eines herkömmlichen Hafenmobilkranes von der Zusatzeinrichtung nicht beeinflußt. Als Wippwerk wird im Schwerlastbetrieb das ohnehin vorhandene Hubwerk des Hafenmobilkranes verwendet, wobei die Kolben-Zylindereinheit des hydraulischen Wippwerkes freigeschaltet wird. Gleichzeitig dient der für den Normalbetrieb vorgesehene Wippzylinder im Schwerlastbetrieb als Rückfallstütze für den Ausleger. Zusätzlich ist für den Schwerlastbetrieb ein weiteres Hubwerk vorzusehen, das zum Heben der schweren Lasten einsetzbar ist. Um Schwerlasten standsicher heben zu können, ist allerdings vorzusehen, das für den Normallastbetrieb ausgelegte Standmoment des Hafenmobilkranes zu erhöhen.With a port crane of the proposed type, the above described Disadvantages avoided. The function and basic construction become one conventional mobile harbor cranes are not affected by the additional device. As In heavy-duty operation, the luffing gear becomes the already existing lifting gear of the Mobile harbor cranes used, the piston-cylinder unit of the hydraulic Rocker is unlocked. At the same time it is used for normal operation provided luffing cylinder in heavy load operation as a fall support for the boom. In addition, another hoist must be provided for heavy-duty operation Heavy loads can be used. To lift heavy loads steadily However, it must be provided that the one designed for normal load operation Increase the standing moment of the mobile harbor crane.

    In einer günstigen Ausgestaltung der Erfindung ist vorgesehen, daß zur Erhöhung des Standmoments des Hafenmobilkranes im Schwerlastbetrieb ein an der dem Ausleger entgegengesetzten Seite am Turm angelenkter Gegenausleger in der vertikalen Auslegerschwenkebene durch einen auch als Rückfallstütze wirkenden Schwenkzylinder vom Turm abspreizbar ist, wobei der Gegenausleger über eine einerseits am Auslegerkopf und andererseits im Fußbereich des Turmes längenveränderbar angeschlagenes Abspannmittel neigungsveränderbar ist und an seinem Kopfende die Tragvorrichtung für das in Bodennähe anhängbare zusätzliche Schwertast-Gegengewicht aufnimmt, dessen Ausladung durch Veränderung der Neigung des Gegenauslegers einstellbar ist.In a favorable embodiment of the invention it is provided that to increase the Standing moment of the mobile harbor crane in heavy load operation on the boom opposite side hinged to the tower in the vertical Boom swiveling level through one that also acts as a fall support Swing cylinder is spreadable from the tower, the counter jib via a on the one hand on the boom head and on the other hand in the foot area of the tower length-adjustable attached guy can be inclined and on at its head end the carrying device for the additional that can be attached near the ground Heavy-duty counterweight picks up, its projection by changing the Tilt of the counter jib is adjustable.

    Durch diese günstige Ausgestaltung der Erfindung wird in sich bekannter Weise das Standmoment des Hafenmobilkranes erhöht. Der Gegenausleger, der während des Normallastbetriebes am Gerät verbleibt, wird dazu durch einen Schwenkzylinder nach hinten abgespreizt und führt und trägt das zusätzliche Schwerlast-Gegengewicht, das an das Kopfende des Gegenauslegers angehängt wird, auf dem erforderlichen Wirkradius. Durch Verstellung der Neigung des Gegenauslegers kann in einem sinnvollen Toleranzbereich die Ausladung und damit das Gegengewichtsmoment problemlos verändert werden.This inexpensive embodiment of the invention is known Standing moment of the mobile harbor crane increased. The counter jib, which during the Normal load operation remains on the device, this is done by a swivel cylinder spread apart at the rear and carries and carries the additional heavy load counterweight, the is attached to the head of the counter jib on the required Effective radius. By adjusting the inclination of the counter jib in one meaningful tolerance range the throat and thus the counterweight moment can be easily changed.

    In einer weiteren günstigen Ausgestaltung der Erfindung ist vorgesehen, daß das längenveränderbar angeschlagene Abspannmittel für den Gegenausleger aus am Auslegerkopf angeschlagenen Abspannstangen bestehen, an deren freiem Enden Umkenkrollen für je ein Seil anlenkbar sind, das im Schwerlastbetrieb am Gegenauslegerkopf befestigt ist und über eine dort angeordnete Umlenkrolle zu einem am Turm angeordneten Einstellwerk (Winde) geführt ist. Mit dieser Lösung kann die Neigung des Gegenauslegers über das Einstellwerk, in der Regel einer Winde, verstellt werden, indem das Seil eingeholt oder nachgelassen wird. In a further advantageous embodiment of the invention it is provided that the Length-adjustable anchoring means for the counter jib from am Cantilever boom struts are attached at their free ends Deflection pulleys can be articulated for one rope each, which in heavy load operation Counter jib head is attached and via a deflection roller arranged there a setting mechanism (winch) arranged on the tower is guided. With this solution the inclination of the counter jib can be adjusted using the setting mechanism, usually one Winch can be adjusted by pulling in or lowering the rope.

    Besonders günstig ist es, wenn im Normalbetrieb des Hafenkranes die am Auslegerkopf angeschlagenen Abspannstangen auf dem Ausleger abgelegt und dort fixiert werden und die von deren freiem Enden gelösten Umlenkrollen jeweils mit eingeschertem Seil am Kopf des Turmes befestigt werden, wobei jedes Seil so eingestellt wird, wie es der Gegenausleger in seiner aufrechten, durch den Schwenkzylinder arretierten Ruheposition vorgibt und die Tragvorrichtung für das abgehängte Schwerlast-Gegengewicht am Oberwagen fixiert ist. Das bedeutet, daß alle wesentlichen Teile der Zusatzeinrichtung zur Erhöhung der Traglast des Hafenmobilkranes am Fahrzeug verbleiben und somit sehr schnell die Umrüstung vom Normalbetrieb zum Schwerlastbetrieb erfolgen kann. Insbesondere bleiben die Seile weitgehend eingeschert, so daß aufwendige Einfädelarbeiten entfallen. In einer weiteren günstigen Ausgestaltung der Erfindung wird vorgeschlagen, daß die Schwerlast-Hakenflasche im Normalbetrieb des Hafenkranes bei eingeschertem Schwerlast-Hubseil in der Nähe des Schwerlast-Hubwerkes am Oberwagen des Hafenkranes zwischengelagert wird. In der Praxis wird die Schwerlast-Hakenflasche bei abgesenktem Ausleger, beispielsweise von einem Gabelstapler aufgenommen, und mit eingeschertem Seil zu einer Haltevorrichtung transportiert, die am Oberwagen des Hafenmobilkranes vorgesehen ist. Gleichzeitig wird das Hubseil mit dem Schwerlast-Hubwerk aufgewickelt, ohne daß es den Rollensatz verläßt. Das Hubseil muß lediglich von der zusätzlich am Ausleger vorgesehenen Führungsrolle abgenommen werden, im übrigen bleiben alle Seile eingeschert.It is particularly favorable if the normal operation of the harbor crane Boom bars attached to the boom are placed on the boom and there are fixed and the pulleys released from their free ends with each sheared rope to be attached to the head of the tower, each rope so is set as the counter jib in its upright position, by the Swivel cylinder locked rest position specifies and the carrying device for that suspended heavy load counterweight is fixed to the superstructure. It means that all essential parts of the additional device to increase the load capacity of the Mobile harbor cranes remain on the vehicle and therefore the conversion very quickly from normal operation to heavy duty operation. In particular, they remain Ropes largely sheared, so that complex threading work is eliminated. In a Another favorable embodiment of the invention it is proposed that the Heavy-duty hook block in normal operation of the harbor crane with a reeving Heavy duty hoist rope near the heavy duty hoist on the superstructure of the Harbor cranes are temporarily stored. In practice, the heavy duty hook block with the boom lowered, for example picked up by a forklift, and transported with a sheared rope to a holding device on the superstructure of the mobile harbor crane is provided. At the same time the hoist rope with the Heavy duty hoist coiled without leaving the roller set. The hoist rope must only from the additional guide roller provided on the boom be removed, otherwise all ropes remain reeved.

    Zur weiteren Reduzierung der Rüstzeiten des Hafenmobilkranes wird vorgeschlagen, das Schwerlast-Gegengewicht fahrbar auszubilden, beispielsweise auf einem Transportwagen, der sehr leicht zu der Einsatzstelle transportiert werden kann, wo die Tragvorrichtung des Gegenauslegers das Schwerlast-Gegengewicht aufnimmt.To further reduce the set-up times of the mobile harbor crane, it is proposed that design the heavy-duty counterweight to be mobile, for example on one Transport trolley that can be transported very easily to the site where the Carrying device of the counter jib picks up the heavy load counterweight.

    Mit der erfindungsgemäßen Zusatzeinrichtung wird eine besonders kostengünstige Ergänzung bestehender Hafenmobilkrantechnik geschaffen. Das Umrüsten eines herkömmlichen Kranes zum Schwerlastkran ist in kürzester Zeit und mit geringstem Aufwand möglich, weil weitgehend alle dazu benötigten Teile am Hafenmobilkran vorhanden bzw. angebracht sind. Der Betreiber des Hafenmobilkranes wird unabhängig von Auto- oder Schiffskranverleihern und kann selbst sein Gerät in kürzester Zeit den Bedürfnissen anpassen. The additional device according to the invention makes it particularly economical Completion of existing mobile harbor crane technology created. Converting one conventional cranes to heavy duty cranes is in the shortest possible time and with the least Effort possible because largely all the parts required on the mobile harbor crane are present or attached. The operator of the mobile harbor crane will independent of car or ship crane rental companies and can even put his device in adapt to the needs in the shortest possible time.

    In Figur 1 ist ein konventioneller Hafenmobilkran dargestellt, der mit einer Schwerlasteinrichtung nach der Erfindung versehen ist. Der Hafenmobilkran ist insgesamt mit 1 bezeichnet. Die Zusatzeinrichtung zur Erhöhung der Tragkraft ist insgesamt mit 2 beziffert. Sie besteht aus dem Gegenausleger 3 und seinem Schwenkzylinder 3.1, den Tragseilen 4, dem Gegengewichtswagen 5, dem Schwerlast-Gegengewicht 6, der Einstellwinde 7, den Abspannstangen 8, dem Einstellwerk 9, dem Schwerlast-Hubwerk 10, der Umlenkrolle 11, dem Rollensatz 12 und der Schwerlast-Hakenflasche 13. Das Schwerlast-Hubwerk 10 ist am Oberwagen des Hafenmobilkranes 1 befestigt. Von dort wird das Hubseil über die Umlenkrolle 11 zum Kopf 1.3 des Auslegers 1.5 geführt, wo es über den Rollensatz 12 zu der Schwerlast-Hakenflasche 13 geleitet wird. Durch Betätigen der Schwerlast-Hubwerkes 10 kann die Schwerlast-Hakenflasche 13 gehoben und gesenkt werden.A conventional mobile harbor crane is shown in FIG Heavy duty device is provided according to the invention. The mobile harbor crane is overall designated 1. The additional device to increase the load capacity is totaled 2. It consists of the counter jib 3 and his Swivel cylinder 3.1, the supporting ropes 4, the counterweight carriage 5, the Heavy duty counterweight 6, the adjusting winch 7, the guy rods 8, the Adjustment mechanism 9, the heavy-duty lifting mechanism 10, the deflection roller 11, the roller set 12 and the heavy duty hook block 13. The heavy duty hoist 10 is on the superstructure of the mobile harbor crane 1 attached. From there, the hoist rope is moved over the deflection roller 11 led to the head 1.3 of the boom 1.5, where it via the roller set 12 to the Heavy duty hook block 13 is passed. By operating the heavy-duty hoist 10, the heavy-duty hook block 13 can be raised and lowered.

    Als Wippwerk für den Ausleger 1.5 dient das eigentliche Hubwerk 1.1 des Hafenmobilkranes 1, das am Oberwagen des Hafenmobilkranes angeordnet ist. Von dort wird das gestrichelt dargestellte Seil über nicht näher bezeichnete Umlenkrollen zum Auslegerkopf 1.3 an der Spitze des Turmes 1.7geführt, wo das bzw. die Hubseile 1.2 fest angeschlagen werden. Durch Betätigen des normalen Hubwerkes 1.1 kann nun der Ausleger 1.5 gewippt werden, wobei der hydraulische Wippzylinder 1.4 freigeschaltet wird und nur noch als Rückfallstütze für den Ausleger 1.5 dient.The actual lifting mechanism 1.1 of the serves as the luffing mechanism for the jib 1.5 Mobile harbor crane 1, which is arranged on the superstructure of the mobile harbor crane. Of there the rope shown in dashed lines is passed over idler pulleys led to the boom head 1.3 at the top of the tower 1.7, where the or the lifting ropes 1.2 are struck firmly. By operating the normal hoist 1.1 the boom 1.5 can now be luffed, with the hydraulic luffing cylinder 1.4 is released and only serves as a fall support for the boom 1.5.

    Die zusätzlichen Querlasten werden durch das Schwerlast-Gegengewicht 6 kompensiert. Dieses Schwerlast-Gegengewicht 6 ist auf dem Gegengewichtswagen 5 herangefahren worden, so daß es unterhalb des Kopfes des Gegenauslegers 3 positioniert ist.
