  Zwillingsportalkran für sperrige Lasten, insbesondere Containerkran 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
B.Einführung in die Verriegelung erleichtert. 



   In Fig. 2 ist ein Umschlagkran für Stückgüter dargestellt, wobei die beiden Krankatzen-3-der beiden   Kranportale--l   und   2--eine   gemeinsame   Lasttraverse-4--betätigen.   



   In Fig. 3 ist ein Containerteilgehänge --6-- im Detail dargestellt, welches an der Hakenflasche 
 EMI2.1 
 verringern, sind nicht dargestellte Vorrichtungen vorgesehen, welche aus gekoppelten Dreigelenkshebeln gebildet werden. 



   In Fig. 4 ist ein   Containerteilgehänge-6-in   einer geänderten Konstruktion dargestellt. Bei dieser Konstruktion hängt das   Teilgehänge-6-direkt   mittels der   Seilrollen--18-in   den Seilen des Hubwerkes der   Krankatzen-3--.   



   Der Containerkran besteht aus zwei Portalkränen und kann ohne Verwendung von 
 EMI2.2 
 Kragarmen ohne konstruktiven Aufwand möglich, da durch die Distanzierung der Kranportale jeweils eine ausreichende Portalöffnungsweite zum Durchfahren der Portalstützen mit den Containern zur Verfügung steht. Die erfindungsgemässe Einrichtung gestattet den wechselweisen Umschlag von Containern und von Stückgütern, wobei in letzterem Betriebsfall bei höheren Lasten die beiden Kräne über eine Lasttraverse zusammenarbeiten. Mit geringen Mehrkosten lässt sich der Kran in unabhängige Teilkräne zerlegen, so dass die Wirtschaftlichkeit der Anlage gehoben wird. 



   PATENTANSPRÜCHE : 
1. Zwillingsportalkran für sperrige Lasten, insbesondere Containerkran, bestehend aus zwei getrennt bewegbaren Kranportalen, deren jedes eine vorzugsweise als Winkelkatze ausgebildete 
 EMI2.3

B. Introduction to the lock facilitated.



   In Fig. 2, a transfer crane for piece goods is shown, the two crane trolleys-3-of the two crane portals - 1 and 2 - operate a common load beam-4.



   In Fig. 3 a container part hanger --6-- is shown in detail, which is attached to the hook block
 EMI2.1
 reduce, devices not shown are provided, which are formed from coupled three-joint levers.



   In Fig. 4 a container part hanger-6-is shown in a modified construction. In this construction, the part suspension-6-hangs directly by means of the pulleys -18-in the ropes of the hoist of the crane trolleys -3--.



   The container crane consists of two gantry cranes and can be operated without using
 EMI2.2
 Cantilever arms possible without constructive effort, since the distance between the crane portals means that there is sufficient portal opening width for the containers to pass through the portal supports. The device according to the invention allows the alternate handling of containers and piece goods, with the two cranes working together via a load traverse in the latter operating case at higher loads. The crane can be dismantled into independent partial cranes at low additional costs, so that the cost-effectiveness of the system is increased.



   PATENT CLAIMS:
1. Twin portal crane for bulky loads, in particular a container crane, consisting of two separately movable crane portals, each of which is preferably designed as an angle trolley
 EMI2.3


 

Claims (1)

(3) in an sich bekannter Weise unabhängig voneinander und auch synchron miteinander von einem Bedienungsstand (12) aus bewegbar sind. EMI2.4 dass die Kranportale (1, 2) in einem Abstand verriegelbar sind, bei welchem der Abstand der Containerteilgehänge (6) etwas kleiner, vorzugsweise 10 cm kleiner ist, als der Abstand der Gehängeanschlusspunkte am Container (7). (3) can be moved in a manner known per se independently of one another and also synchronously with one another from an operating station (12). EMI2.4 that the crane portals (1, 2) can be locked at a distance at which the distance between the container part hangers (6) is slightly smaller, preferably 10 cm smaller, than the distance between the hanger connection points on the container (7).
