Abstract
Description
Beschreibung: Description:
Baukran mit erhöhter Reichweite.Construction crane with increased reach.
Auf großen Baustellen werden vielfach eine grössere Zahl von Baukranen beobachtet, die trotzdem das Mittelfeld kaum und dann nur mit vers verminderten Gewichtslasten erreichen. Spezial- oder Riesenkrane, die diesen Mängeln teilweise abhelfen könnten, sind unwirtschaftlichs da sie nur beschränkt einsatzfähig sind. Der vorliegende Vorschlag sieht statt dessen vor, normale Ausleger-Baukrane mit Laufkatzen' die überall einsatzfähig sind, mittels einer zusätzlichen relativ einfachen und daher preisgünstigen Konstruktion, zu verwenden. Grundsätzlich können dazu bisher verwendete Baukrane geeignet sein. Bei Neufertigung ist es aber zweck mässig, die Ausleger den besonderen Anforderungen etwas anzupassen.A large number of construction cranes are often used on large construction sites observed, which nevertheless barely reduced the midfield and then only reduced it with verse Achieve weight loads. Special or giant cranes that partially address these shortcomings could help are uneconomical because they are only of limited use. Instead, the present proposal provides for normal jib construction cranes Trolleys' which can be used anywhere, by means of an additional relatively simple one and therefore inexpensive construction to use. Basically you can do this so far construction cranes used must be suitable. In the case of new production, however, it is advisable to use the To adapt the boom to the special requirements.
Der Vorschlag sieht vor, dass Jeweils zwei identische Baukrane mit Ausleger und Laufkatze auf Schienen gegenüber gestellt werden und wobei die Ausleger zueinander zeigen. Der Zwischenraum zwischt den Enden der Ausleger wird mit einem Mittelstück ähnlicher Konstruktion wie die Ausleger, überbrückt. Das Mittelstück ist aus Fertigteilen zusammengesetzt und hat den Zwischenraum zwischen den Ausleger-Enden auszufüllen. Das Zwischenstück kann auf dem AuS leger vormontiert und mit diesem hochgehoben werden. Es wird dann vom Ausleger aus vorgescnoben und mit den Enden der Ausleger fest verschraubt. Es kann aber auch in Teilen hochgebracht werden und dann vom Ausleger aus vorgebaut werden. Übersteigt das Gewichl des Zwischenstückes die Tragfähigkeit des Auslegers (nach dem Hebelgesetz), so kann während der Montage auch der Ballast entsprechend erhöht werden, was unbedenklich ist, da der Kran während der Montage nicht bewegt wird. Evtl. ist zur Montage z.B. bei sehi großen Spannweiten, auch eine seitliche St'1ze zweckmässig. Abmontieren dann auf umgekehrte Weise.The proposal provides that two identical construction cranes with Boom and trolley are placed opposite each other on rails and with the boom point to each other. The space between the ends of the boom is made with a Middle piece of similar construction to the boom, bridged. The middle piece is composed of prefabricated parts and has the space between the ends of the boom to be filled out. The intermediate piece can be preassembled on the Auser and with it be lifted up. It is then snubbed from the boom and with the ends the boom is firmly screwed. But it can also be brought up in parts and then be built in front of the boom. Exceeds the weight of the intermediate piece the load-bearing capacity of the boom (according to the law of levers), so can be done during assembly the ballast can also be increased accordingly, which is harmless since the crane during is not moved during assembly. Possibly for assembly, e.g. with very large spans, a side support is also useful. Then dismantle on reverse Way.
Wird der Kran in Betriebgenommen, kann evtl, der ganze Ballast abgebaut werden. Die Motoren der beiden Krane sind entsprechenz parallel zu schalten und die Motoren für die Drehbewegung der Ausleger auszuschalten. Die beiden Trane sind durch die steife verbindung mit dem Zwischenstück zu einem Brückenkran mit Laufkatze geworden. Dieser Brückenkran kann die ganze Baustelle abfahren. Wenn die Geleise sehr lang sind kann darau.If the crane is put into operation, all of the ballast can possibly be dismantled will. The motors of the two cranes are to be connected in parallel and switch off the motors for rotating the booms. The two Trane are due to the rigid connection with the intermediate piece to a bridge crane with trolley become. This bridge crane can travel the entire construction site. When the rails can be very long.
wenn erforderlich, noch zusätzlich ein üblicher Baukran arbeiten. Es lassen sich so sehr große und breite Bauflächen auch mit relativ schweren Fertigbauteilen oder anderen schweren Einzelteilen bedienen. Nach Demontage des Wittelstückes sind die beiden Krane wieder als Einzelkrane voll einsetzbar. Leerseiteif necessary, a standard construction crane can also be used. Very large and wide building areas can be created, even with relatively heavy prefabricated components or other heavy parts. After dismantling the center piece the two cranes can be fully used as single cranes again. Blank page
