Abstract

The construction of the joint and the corresponding shape of the boom segment, permits segment sliding during folding. Through use of hydraulics, when folding down to the U-configuration, the design allows the segments to be pushed into each other.

Description

Die Erfindung besteht aus einem Mobilkran, der mit Gelenken (siehe 1) ausgestattet ist, die ein Abklappen (siehe 2; 3), wie in Anspruch 1, der teleskopischen Segmente in verschiedenste Winkelbereiche ermöglichen.The invention consists of a mobile crane with joints (see 1 ), which folds down (see 2 ; 3 ), as in claim 1, allow the telescopic segments in various angular ranges.

Bis heute wird zwischen Turmdrehkran und Mobilkran deutlich unterschieden, und es gibt auch bis heute nur wenige Kompromissmodelle, die die Vorteile eines Mobilkrans mit denen des Turmdrehkrans vereinen. ( DE 43 15 960 A1 ), ( EP 1 048 605 A1 ), ( DE 697 29 359 T2 ), ( DE 299 16 410 U1 ) zeigen, dass es möglich ist, einen Turmdrehkran falten zu können und diesen auf einem Mobilkranfahrgestell aufzubauen.To date, there is a clear distinction between tower crane and mobile crane, and even today there are only a few compromise models that combine the advantages of a mobile crane with those of the tower crane. ( DE 43 15 960 A1 ) EP 1 048 605 A1 ) DE 697 29 359 T2 ) DE 299 16 410 U1 ) show that it is possible to fold a tower crane and build it on a mobile crane chassis.

EP 1 048 605 A1 beschreibt DE 43 15 960 A1 mit Mobilkranfahrgestell. EP 1 048 605 A1 describes DE 43 15 960 A1 with mobile crane chassis.

DE 697 29 359 T2 beschreibt einen Mobilkran, dessen teleskopischer Ausleger in zwei Partitionen unterteilt ist und bei dem die Zweite Partition senkrecht zur ersten geklappt werden kann. DE 697 29 359 T2 describes a mobile crane, whose telescopic boom is divided into two partitions and in which the second partition can be folded perpendicular to the first.

DE 29916 41 U1 beschreibt den naheliegensten Vorgänger der Erfindung, es ist ein teleskopierbarer Turmdrehkran, der auf einem Mobilkranfahrgestell aufgebaut ist. Jedoch ist diese Variante nur in ihrer vorgegeben Aufbauweise nutzbar. Wenn der Kran auf 30 m Höhe und 60 m Ausleger ausgelegt ist, so kann man daran nichts ändern, zum Beispiel nicht auf 60 m Höhe und 30 m Ausleger wechseln. DE 29916 41 U1 describes the nearest predecessor of the invention, it is a telescopic tower crane, which is built on a mobile crane chassis. However, this variant is usable only in their predetermined structure. If the crane is designed for a height of 30 m and a boom of 60 m, then you can not change it, for example, do not change to a height of 60 m and a boom of 30 m.

Die Erfindung besteht darin, dass ein Mobilkran mit den in Anspruch 2 erwähnten Gelenken (siehe 1) und Segmenten die Möglichkeit besitzt, sich in einen Turmdrehkran zu „verwandeln", mit weniger Raumbeanspruchung. Er kann diese „Verwandlung" auch während einer Lastabwicklung durchführen, auch kann er jedes beliebige Höhe-Ausleger-Verhältnis im Rahmen der Anzahl und Länge der teleskopischen Segmente erreichen.The invention is that a mobile crane with the joints mentioned in claim 2 (see 1 ) and segments have the ability to "transform" into a tower crane, with less space stress.He can perform this "transformation" even during a load handling, he can also any height-cantilever ratio in the context of the number and length of the telescopic Reach segments.

Die Erfindung kann durch den aktuellen Stand der Technik leicht umgesetzt werden, da das Fahrgestell von herkömmlichen Autokränen verwendet werden kann und nur der Aufsatz gewechselt werden muss. Da die Segmente der Erfindung

Figure 00010001
(siehe 4) gestaltet sind, können sie weiterhin teleskopisch ausgefahren werden, doch sie können auch problemlos auseinander geklappt werden, da das daran hindernde „Dach", die oben abschließende Platte fehlt. Die Gelenke sind gestaltet wie die Segmente, jedoch besitzen sie zudem noch eine Führung an der oberen Kante. Da die Segmente nun nicht mehr über die übliche, innen laufende, Seilwinde auseinander gezogen werden, arbeiten hier nun Bremsschrittmotoren über Zahnräder.The invention can be easily implemented by the current state of the art, since the chassis of conventional truck cranes can be used and only the attachment must be changed. As the segments of the invention
Figure 00010001
(please refer 4 ), they can still be extended telescopically, but they can also be easily unfolded because the obstructing "roof", the top plate missing.The joints are designed as the segments, but they also have a guide on Since the segments are no longer pulled apart by the usual inward-running winch, brake stepper motors now operate via gears.

Die gesamten Gelenke sind an einer verbreiterten Verlängerung des jeweiligen Segments mit einem Stahlrohr angebracht. Die dazugehörige Hydraulik ist am vorderen Ende der Unterseite des jeweiligen Gelenks und der vordersten Kante der Unterseite des jeweils dazugehörigen Segments angebracht (siehe 1)The entire joints are attached to a widened extension of the respective segment with a steel tube. The associated hydraulics are attached to the front end of the underside of the respective hinge and the foremost edge of the underside of the respective segment (see 1 )

In der Großstadt ist die Erfindung am effizientesten einsetzbar. Da dieser Mobilkran auch wie ein Turmdrehkran arbeiten kann, können hier Arbeiten an Hochhäusern schneller und kostengünstiger fertiggestellt werden. Normale Turmdrehkräne müssen erst in tagelanger Arbeit aufgestellt werden und bestehen aus vielen Bauteilen, die erst zum Aufstellungsort transportiert werden müssen, dieser Mobilkran hingegen ist in wenigen Minuten einsatzbereit und somit nicht über Tage zu mieten.In the city is the invention most efficient use. Since this mobile crane can also work like a tower crane, can here work on high-rise buildings completed faster and cheaper become. Normal tower cranes need only in days Work and are made up of many components that first have to be transported to the site, this Mobile crane, however, is ready in a few minutes and thus not to rent for days.

Hauptvorteil ist, neben der verkürzten Aufstelldauer, dass das Gelenk, welches nicht nur das Umwandeln von Mobilkran zu Turmdrehkran während einer Lastabwicklung ermöglicht, sondern auch eine Verschiebung der Segmente jederzeit gewährleistet, unter Ersetzung der Laufkatze eines Turmdrehkrans.main benefit is, in addition to the shortened setup time, that the joint, which not only converting from mobile crane to tower crane during a load handling allows, but also a shift the segments guaranteed at any time, replacing the Trolley of a tower crane.
