Abstract

It is proposed a Brückenlege- / multi-purpose trailer, which is pulled by a sufficiently heavy towing vehicle and a bridge laying device including bridge parts receives to inexpensively produce a quick bridge when needed for military and other operations as well as a standard container u. a. to be able to transport as a secondary use.

Description

The The invention relates to a bridge laying unit according to the The preamble of claim 1 mentioned features and the Use in a train.

By the political need, international crises and wars preferably immediately with military To be able to counter resources the armed forces the procurement of defense material more and more on lightweight luftverlegbare / luftverlastbare Systems off.

In all international crisis and war missions of the recent past be established that transport infrastructure, in particular the traffic route network with its bridges, largely destroyed and thus were useless. This makes the use of Pioneer and translating means necessary to ensure the mobility of their own troops.

For this came to date laying bridges For use with heavy tracked vehicles (Brückenlegepanzer (BrPz) on battle tank chassis) were transported and relocated. These BrPz can be because of their dimensions and because of their Do not carry weight with international standard airplanes and thus do not meet the requirement for Luftverlegbarkehit.

To The prior art has made various proposals for laying bridges.

In the EP 0172695 B1 a tracked vehicle is shown as a bridge-laying, which piggybacks two bridge parts, which can be successively pushed out to a bridge of large span.

In the DE 198 58 328 C1 a lightweight mobile bridge is proposed, wherein the bridge parts are composable and consist of upper and lower chords of fiber composite material.

From the DE 200 21 451 U1 For example, a lightweight single-sided mobile bridge is known for crossing obstacles with vehicles, assembling individual truss segments and unrolling the bridge from an exit side over the obstacle and crossing the obstacle.

In the EP 0988424 B1 describes a modular bridge, which is formed by at least two coupled short bridge parts, wherein the ramp tips of the short parts are partially raised and a continuous longer bridge with ramps is formed.

• – Verlegebrücken auf Brückenlegepanzern
• – Brücken, die aus Einzelteilen vor Ort manuell errichtet werden müssen.

The following bridges are currently used by the armed forces:

• - Laying bridges on bridge support armor
• - Bridges which must be manually erected from individual parts on site.

adversely at the mentioned bridges is that they are either not transported by air freight can due to their weight and their geometric dimensions or that for their construction a long period of time, for example several hours, needed and this setup is therefore not in a time-critical tactical Use can be made.

• – Zulassung der Brücke für Fahrzeuge großen Gewichts mit MLC 60 (Militärische Lastenklasse 60) und höher,
• – Zulassung der Brücke für alle militärischen Fahrzeuge mit Spurweiten zwischen ca. 2 m und mehr als 3,5 m,
• – Spannweite der Brücke von mindestens 20 m,
• – Gesamtgewicht der Brücke einschließlich Transport- und Verlegesystem weniger als 33 t,
• – Maximale Breite der Brücke einschließlich Transport- und Verlegesystem weniger als 3m beim Straßentransport.

The problem is that a trade-off for an air-powered docking bridge is the combination of multiple claims. These requirements are as follows:

• - Approval of the bridge for heavy vehicles with MLC 60 (Military Load Class 60) and higher,
• - Approval of the bridge for all military vehicles with gauges between approx. 2 m and more than 3.5 m,
• - span of the bridge of at least 20 m,
• - total weight of the bridge including transport and installation system less than 33 t,
• - Maximum width of the bridge including transport and installation system less than 3m in road transport.

task The invention is to avoid the disadvantages described and the mentioned conflict of interests as possible largely dissolve.

These The object is achieved by the characterizing features of claim 1 solved. Other features result from the dependent claims.

there The requirements mentioned are to be met by a bridging / multipurpose trailer. A correspondingly designed trailer, the from a towing vehicle, for example an armored wheeled vehicle or a tracked vehicle picks up a laying bridge.

According to the multipurpose capability is achieved in that when scanned by the trailer laying bridge by means of appropriate brackets, for example, an ISO-standard container can be transported on the trailer or trailer for transport of a defective Vehicle can be used. At the rear of the trailer are extendable hydraulic supports, which together with the coupling on the towing vehicle can bring a firm footing for the laying trailer. The laying system for the bridge is adapted and fixed on the trailer and corresponds to a known installation system of a bridge laying vehicle. The hydraulic supply for the laying system is carried on the trailer and electrically operated, the required power is obtained, for example, from the towing vehicle. This hydraulics can also be used for the drive to accommodate an ISO container.

• – der Anhänger für sich mit oder ohne aufgelasteter Brücke luftverlastbar ausgeführt wird durch Einhaltung entsprechender Abmessungen und Gewicht.
• – das bekannte Verlegesystem für Brückenteile unverändert für den Anhänger adaptiert und verwendet wird und der Anhänger entsprechend ausgebildet wird,
• – das modulare Brückenteile auf dem Anhänger transportiert werden, die eine Brückenspannweite von mehr als 20 m erlauben,
• – die Brückenteile in der Breite einstellbar sind und damit auch eine Fahrzeugspurweite von 3,50 m bedient werden kann, wobei die Breite des Anhängers 3m nicht überschreitet,
• – der Anhänger eine einfache und kostengünstige Lösung im Vergleich zum Brückenlegepanzer darstellt,
• – ein Brückenlegeanhänger im Vergleich zu einem Brückenlegepanzer sowohl in der Entwicklung, als auch in der Beschaffung und im Unterhalt um mindestens eine Größenordnung kostengünstiger ist,
• – im Gegensatz zum bekannten Brückenleger, der nach dem Verlegen der Brücke praktisch zu keinen anderen Missionen eingesetzt werden kann, kann der vorgeschlagene Brückenlegeanhänger für weitere Zwecke zum Beispiel Containertransport benutzt werden,
• – mittels der Hydraulikstützen am Anhängerheck der Anhänger horizontal ausgerichtet oder am Heck abgehoben werden kann, so dass ein Verlegen der Brücke bei ansteigendem Gelände ermöglicht wird,
• – zur Unterstützung beim Rangieren die Achsen des Brückenlegeanhängers optional lenkbar ausgeführt sind.

The advantages of the invention are that the target conflict described above is largely solved by the fact that

• - The trailer is designed for air-loadable with or without unbastened bridge by maintaining appropriate dimensions and weight.
• The known laying system for bridge parts is adapted and used unchanged for the trailer and the trailer is designed accordingly,
• - the modular bridge parts are transported on the trailer, allowing a bridge span of more than 20 m,
• - The bridge parts are adjustable in width and thus a vehicle gauge of 3.50 m can be operated, the width of the trailer does not exceed 3m,
• The trailer is a simple and inexpensive solution compared to the bridge armor,
• A bridge laying trailer is at least an order of magnitude cheaper in terms of development, procurement and maintenance compared to a bridge-laying armor,
• In contrast to the known bridge layer, which can practically not be used after the laying of the bridge for any other missions, the proposed bridge laying trailer can be used for further purposes, for example container transport,
• - By means of the hydraulic struts on the trailer tail the trailer can be aligned horizontally or lifted off at the rear, so that an installation of the bridge on rising terrain is made possible
• - To assist in maneuvering the axes of the bridge laying trailer are designed to be optional steerable.
