Abstract
Der Twin-Spreader dient zur Aufnahme von Containern unterschiedlicher Längen oder von zwei kurzen Containern. Er hat einen kastenförmigen Mittelträger (12) mit einer Aufhängevorrichtung (14) zur Verbindung mit einem Kran oder dergleichen sowie teleskopierbare Holme, von denen die Endholme (20) jeweils einen quer zur Ausfahrrichtung verlaufenden Kopfbalken (22) mit Twistlocks (24) aufweisen. Gemäß der Erfindung ist vorgesehen, dass die Endholme (20) mit den Kopfbalken (22) durch Bolzen (34) miteinander verbunden sind.The twin spreader is used to hold containers of different lengths or two short containers. It has a box-shaped center support (12) with a suspension device (14) for connection to a crane or the like and telescopic spars, of which the end spars (20) each have a transverse to the extension direction head bar (22) with twist locks (24). According to the invention, it is provided that the end spars (20) are connected to the head beams (22) by bolts (34).
Description
Die Erfindung betrifft einen Twin-Spreader zur Aufnahme von Container, umfassend einen kastenförmigen Mittelträger mit einer Aufhängevorrichtung zur Verbindung mit einem Kran oder dergleichen sowie teleskopierbare Holme, von denen die Endholme jeweils einen quer zur Ausfahrrichtung verlaufenden Kopfbalken mit Twinlocks aufweisen.The Invention relates to a twin spreader for receiving containers, comprising a box-shaped center support with a suspension device for connection to a crane or the like and telescopic Spars, of which the end spars each one transverse to the extension direction have running head beams with Twinlocks.
Derartige Twin-Spreader dienen zur Aufnahme von Container unterschiedlicher Längen oder von zwei kurzen Container zu je 20 Fuß Länge, wozu die Holme teleskopisch auf die erforderliche Länge ausgefahren werden können. Bisher ist es üblich, die Endholme aus Längsträgern herzustellen, die über Schweißverbindungen mit dem Kopfbalken fest verbunden sind. Das hat den Nachteil, dass durch die Schweißverbindungen erhebliche Spannungen im Bereich des Kopfbalkens hervorgerufen werden. Darüber hinaus ist der exakte Zusammenbau arbeitsaufwändig und erfordert die Einhaltung genauer Toleranzen, die beim Schweißen oftmals nicht eingehalten werden können.such Twin spreaders serve to accommodate different containers lengths or of two short containers of 20 feet each, to which the spars telescopically to the required length can be extended. So far, it's common to manufacture the end beams from side rails, the over welded joints are firmly connected to the head bar. This has the disadvantage that through the welded joints considerable stresses in the area of the headbeam are caused. Furthermore Precise assembly is laborious and requires compliance exact tolerances that are often not met during welding can be.
Der Erfindung liegt die Aufgabe zugrunde, einen Spreader der eingangs umrissenen Bauart zur Verfügung zu stellen, bei dem die Endholme mit ihren Kopfbalken spannungsfrei und leicht montiert werden können, um eine Serienfertigung kostengünstiger zu gestalten.Of the Invention is based on the object, a spreader of the above outlined type available to provide, in which the end spars with their head beams tension-free and can be easily mounted, to make mass production more cost-effective to design.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, dass die Endholme mit den Kopfbalken über Bolzen miteinander verbunden sind. Eine derartige Verbindung kann ohne Nachteile für die starre Fixierung der Einzelteile miteinander einfach und rasch durchgeführt werden, was sich auch kostensenkend auf die Endmontage auswirkt.According to the invention this task is solved by that the end spars are connected to the head beams via bolts are. Such a connection can be without disadvantages to the rigid Fixing the items together easily and quickly, which also has a cost-reducing effect on the final assembly.
Die Verbindung kann nach einem weiteren Merkmal der Erfindung so gestaltet sein, dass jeder Endholm aus zwei parallelen Längsträgern besteht, die teleskopierbar in einem Zwischenholm oder in dem Mittelträger gelagert sind und an deren Enden der Kopfbalken durch Steckverbindung befestigt und mittels Bolzen fixiert ist. Dabei ist es von besonderem Vorteil, wenn einer der beiden Längsträger in Draufsicht L-förmig ausgebildet ist, wobei der kurze L-Schenkel parallel zum Kopfbalken verläuft und mit diesem durch die Steckverbindung und die Bolzen verbunden ist, während das dem Kopfbalken zugewandte, äußere Ende des zweiten Längsträgers in dem freien Ende des kurzen L-Schenkels durch Steckverbindung und Bolzen fixiert ist.The Connection can be designed according to a further feature of the invention be that each end spar consists of two parallel side members, the telescopic are stored in an intermediate spar or in the center carrier and at the Ends of the head beams fastened by plug connection and by means of Bolt is fixed. It is particularly advantageous if one the two side members in plan view L-shaped is formed, wherein the short L-leg is parallel to the head bar and connected to this by the connector and the bolts, while the head beam facing, the outer end of the second side member in the free end of the short L-leg through plug connection and bolt is fixed.
Die Erfindung ist nachstehend an einem Ausführungsbeispiel erläutert, das in der Zeichnung dargestellt ist. Es zeigen:The Invention is explained below using an embodiment which is shown in the drawing. Show it:
