Description

Die Erfindung betrifft ein Verfahren zum Verlegen eines Brückenelements mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1 und eine Vorrichtung zum Verlegen eines Brückenelements mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 5.The invention relates to a method for laying a bridge element with the features of the preamble of patent claim 1 and a device for laying a bridge element with the features of the preamble of claim 5.

Die Erfindung kann Einsatz finden an zivilen und militärischen Rad- oder Kettenfahrzeugen zum Verlegen von mobilen Brücken, welche zumeist aus mehreren einzelnen mit dem Fahrzeug mitgeführten Brückenelementen bestehen. Für das Verlegen der zumeist in Längs- und Querrichtung symmetrischen Brückenelemente weisen solche Fahrzeuge einen verschwenkbaren Verlegearm auf. An dem Verlegearm sind Antriebselemente angeordnet, welche die Brückenelemente während des Verlegens in Längsrichtung bewegen. Häufig weist der Verlegearm als Antriebselemente insbesondere ein Paar Triebstockräder im mittleren Bereich des Verlegearms auf, welche mit zwei entsprechenden Triebstöcken am Brückenelement zusammenwirken und dieses bewegen, vgl. GB 22 85 825A . Hilfsweise wird ein weiteres Paar von Triebstockrädern verwendet, welches im hinteren Bereich des Verlegearms angeordnet ist.The invention can be used on civil and military wheeled or tracked vehicles for laying mobile bridges, which usually consist of several individual bridge elements carried along with the vehicle. For the laying of the bridge elements, which are usually symmetrical in the longitudinal and transverse directions, such vehicles have a pivotable laying arm. On the laying arm are drive elements arranged, which move the bridge elements during laying in the longitudinal direction. Often, the laying arm has as drive elements in particular a pair of drive stick wheels in the middle region of the laying arm, which interact with two corresponding drive sticks on the bridge element and move it, cf. GB 22 85 825A , Alternatively, another pair of Triebstockrädern is used, which is arranged in the rear region of the laying arm.

Die einzelnen Brückenelemente sind zumeist auf dem Fahrzeug gestapelt. Während des Verlegens wird zuerst das oberste Brückenelement mit dem Verlegearm in der Horizontalen in Längsrichtung geführt nach vorne bewegt, so dass es nahezu vollständig nach vorne über das Fahrzeug übersteht. In dem Fall, in dem noch weitere Brückenelemente verlegt werden sollen, wird ein zweites Brückenelement vom Stapel mittels der Triebstockräder nach vorne bis zum ersten Brückenelement bewegt, wo die beiden Brückenelemente miteinander starr gekoppelt werden. Nach der Kopplung werden beide Brückenelemente nach vorne bewegt, bis auch das zweite nahezu vollständig nach vorne über das Fahrzeug übersteht. Dieser Vorgang wird wiederholt, bis die gewünschte Anzahl von Brückenelementen gekoppelt ist. Dann wird der verschwenkbare Verlegearm in einer vertikalen Ebene derart verschwenkt, dass erst das vordere Ende des ersten Brückenelements auf den Boden aufsetzt und anschließend das hintere Ende des letzten Brückenelements.The individual bridge elements are usually stacked on the vehicle. During laying, first the top bridge element is moved with the laying arm in the horizontal direction in the longitudinal direction moved forward so that it protrudes almost completely forward over the vehicle. In the case in which even more bridge elements are to be laid, a second bridge element is moved from the stack by means of the drive stick wheels forward to the first bridge element, where the two bridge elements are rigidly coupled together. After coupling, both bridge elements are moved forward until the second projects almost completely forward over the vehicle. This process is repeated until the desired number of bridge elements are coupled. Then, the pivotable laying arm is pivoted in a vertical plane such that only the front end of the first bridge element touches the ground and then the rear end of the last bridge element.

Während des Verlegens muss das Brückenelement kontrolliert bewegt werden. Insbesondere darf das Brückenelement beim Absetzen des vorderen Endes nicht aus der Führung geraten und durchrutschen. Das fehlerfreie Absetzen der Brücke muss insbesondere auch an abschüssigen Ebenen, beispielsweise an einer Uferböschung, und bei ungünstigen Bodenbedingungen (z.B. bei Schlamm) gewährleistet sein. Auf Grund der sich ergebenden Winkelverhältnisse ist das Verlegen und Aufnehmen von nur einem Brückenelement häufig kritischer als das Verlegen von mehreren Brückenelementen.During installation, the bridge element must be moved in a controlled manner. In particular, the bridge element must not fall out of the guide when settling the front end and slipping. The fault-free discontinuation of the bridge must especially on sloping levels, such as on a bank slope, and unfavorable Soil conditions (eg mud) can be guaranteed. Due to the resulting angular relationships, laying and picking up only one bridge element is often more critical than laying multiple bridge elements.

Das Rutschen der Brücke kann mit den bekannten Vorrichtungen nur durch den Einsatz zusätzlicher Hilfsmittel verhindert werden. Dazu gehört beispielsweise das Anbringen von Kettenzügen zwischen der Verlegeeinrichtung und dem Brückenelement oder zwischen dem Brükkenelement und einem festen Punkt im Umgebungsgelände. Eine weitere Möglichkeit besteht darin, die Brücke durch den Einsatz weiterer mobiler Geräte wie Gabelstapler oder Bergepanzer zu sichern. Nachteilig hierbei ist allerdings zum Einen der erhöhte Aufwand und zum Anderen, dass die Brücke nicht vollständig aus dem gepanzerten Fahrzeug heraus verlegt werden kann, wodurch die Personen-Sicherheit, insbesondere während eines Kampfeinsatzes, gefährdet ist.The sliding of the bridge can be prevented with the known devices only by the use of additional aids. This includes, for example, the attachment of chain hoists between the laying device and the bridge element or between the bridge element and a fixed point in the surrounding area. Another option is to secure the bridge by using other mobile devices such as forklifts or armored recovery vehicles. The disadvantage here, however, on the one hand, the increased effort and on the other hand, that the bridge can not be completely relocated out of the armored vehicle, whereby the personal safety, especially during a combat mission, is at risk.

Die DE 37 38 763 A1 beschreibt ein Brückenverlegefahrzeug mit einem Verlegearm, der ein Sicherungselement zum Sichern der Brücke beim Verlegevorgang aufweist. Bei einer ersten Ausgestaltung ist das Sicherungselement als verschwenkbarer Sicherungsarm mit einer Rastmulde ausgestaltet, in die eine Tragrolle des Brückenelements eingreifen kann. Bei einer zweiten Ausgestaltung weist der Verlegearm einen Sicherungsbolzen auf, der seitlich ausfahren und in eine Ausnehmung am Brückenelement eingreifen kann. Beide Ausgestaltungen dienen dazu, das Brückenelement beim Verlegevorgang mit dem Verlegearm zu verriegeln. Nachteilig an einer solchen Verriegelung ist unter anderem, dass bei ungünstigen Winkelverhältnissen oder Überlastungen ein Bruch einer Komponente auftreten kann.The DE 37 38 763 A1 describes a bridge laying vehicle with a laying arm, which has a securing element for securing the bridge during the laying process. In a first embodiment, the securing element is designed as a pivotable securing arm with a detent recess into which a support roller of the bridge element can engage. In a second embodiment, the laying arm has a securing bolt, which can extend laterally and engage in a recess on the bridge element. Both embodiments serve to lock the bridge element during the laying process with the laying arm. A disadvantage of such a lock is, inter alia, that under unfavorable angular conditions or overloads breakage of a component can occur.

Aufgabe der Erfindung ist es, eine unkontrollierte, fehlerhafte Bewegung des Brückenelementes während des Verlegens und Aufnehmens zu verhindern.The object of the invention is to prevent an uncontrolled, erroneous movement of the bridge element during laying and picking.

Die Erfindung löst die Aufgabe verfahrensmäßig mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1 und vorrichtungsmäßig mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 5. Vorteilhafte Weiterbildungen des Verfahrens und der Vorrichtung sind in den abhängigen Ansprüchen enthalten.The invention solves the problem procedurally with the features of the characterizing part of patent claim 1 and device with the features of the characterizing part of claim 5. Advantageous developments of the method and apparatus are included in the dependent claims.

Ein Grundgedanke der Erfindung liegt darin, im Bereich des Absetzendes des Verlegearms ein Eingreifelement einer Bremseinrichtung anzuordnen, welches mit dem Brückenelement beim Verlegevorgang zusammenwirkt. Die Bremseinrichtung ist bremsbar ausgeführt, damit sie das Brückenelement, insbesondere mittels eines Bremselements, abbremsen kann, damit eine unkontrollierte Bewegung verhindert wird. Die Bremseinrichtung, insbesondere das Eingreifelement, kann im Bereich des Absetzendes angeordnet sein, da an diesem Punkt das Brükkenelement mit dem Verlegearm bis zum Absetzen, d.h. so lange wie möglich in Kontakt ist.A basic idea of the invention is to arrange an engagement element of a braking device in the region of the weaning end of the laying arm, which interacts with the bridge element during the laying process. The braking device is designed to be braked so that it can brake the bridge element, in particular by means of a braking element, so that an uncontrolled movement is prevented. The braking device, in particular the engaging element, can be arranged in the region of the settling end, since at this point the bridge element is in contact with the laying arm until settling out, ie as long as possible.

In einer möglichen Ausgestaltung übt die Bremseinrichtung während des gesamten Verlegevorgangs eine Bremswirkung auf das Brükkenelement aus, um im Vorhinein eine unkontrollierte Bewegung zu verhindern.In one possible embodiment, the braking device exerts a braking effect on the bridge element during the entire laying process in order to prevent uncontrolled movement in advance.

In einer weiteren Ausgestaltung kann die Geschwindigkeit der Bewegung des Brückenelements zudem mittels mindestens eines Messelements gemessen und mittels eines an das Messelement angeschlossenen Überwachungselements, welches eine Elektronik umfassen kann, überwacht werden, weiches im Falle einer fehlerhaften, unkontrollierten Bewegung ein Fehlersignal für das Bremsen abgibt, so dass der Verlegevorgang abgebrochen werden kann. Die Überwachung kann beispielsweise derart erfolgen, dass der gemessene Wert der Geschwindigkeit mit einem vorgegebenen und insbesondere einstellbaren Schwellwert verglichen wird. Sobald der gemessene Wert den Schwellwert übersteigt, wird das Signal zum Bremsen der Bremseinrichtung abgegeben. Die Bremseinrichtung kann also ein Eingreifelement, ein Bremselement, ein Messelement und ein Überwachungselement umfassen. Vorteilhafterweise umfasst das Eingreifelement zumindest ein Brems-Triebstockrad, welches in einen Triebstock des Brückenelements eingreift. An das Brems-Triebstockrad kann ein Rotationsencoder mit einer angeschlossenen Elektronik angeschlossen sein, welche die Drehbewegung des Brems-Triebstockrads und somit die Bewegung des Brükkenelements überwacht.In a further refinement, the speed of movement of the bridge element may also be measured by means of at least one measuring element and monitored by means of a monitoring element connected to the measuring element, which may comprise an electronic unit which emits an error signal for braking in the event of a faulty, uncontrolled movement, so that the laying process can be canceled. The monitoring can be performed, for example, such that the measured value of the speed is compared with a predetermined and in particular adjustable threshold value. As soon as the measured value exceeds the threshold value, the signal for braking the braking device is output. The braking device may thus comprise an engagement element, a brake element, a measuring element and a monitoring element. Advantageously, the engaging element comprises at least one brake Triebstockrad, which engages in a drive block of the bridge element. A rotary encoder with connected electronics can be connected to the brake drive wheel, which monitors the rotational movement of the brake drive wheel and thus the movement of the bridge element.

Als Bremselement kann eine Lamellenbremse, insbesondere eine hydraulisch gelüftete Federdruck-Lamellenbremse, verwendet werden. Zwecks Verringerung der Bremsmomente und damit Verringerung der Bauteilabmessungen der Bremse kann eine Getriebestufe zwischen das Bremselement und das Eingreifelement geschaltet werden.As a brake element, a multi-disc brake, in particular a hydraulically released spring pressure multi-disc brake can be used. In order to reduce the braking torque and thus reduce the component dimensions of the brake, a gear stage between the brake element and the engaging element can be switched.

In einer vorteilhaften Ausgestaltung kann im Bereich des Absetzendes des Verlegearms mindestens ein Rollenelement angeordnet sein, auf welchem das Brückenelement verschiebbar gelagert ist. Das Rollenelement und das Brems-Triebstockrad können derart angeordnet sein, dass der Triebstock des Brückenelements während des Verlegens zwischen ihnen verschiebbar angeordnet ist. Hierdurch wird sichergestellt, dass das Brückenelement bis zum Absetzen mit dem Verlegearm in Kontakt bleibt.In an advantageous embodiment, at least one roller element may be arranged in the region of the weaning end of the laying arm, on which the bridge element is displaceably mounted. The roller element and the brake drive wheel can be arranged such that the drive block of the bridge element is displaceably arranged between them during the laying. This will ensure that the bridge element remains in contact with the laying arm until it settles.

Die Vorteile der Erfindung ergeben sich in analoger Weise auch beim Aufnehmen eines Brückenelements mit dem Verlegearm.The advantages of the invention result in an analogous manner also when receiving a bridge element with the laying arm.

Die Bremseinrichtung kann neben der Sicherung gegen ein Durchrutschen noch weitere Funktionen ausführen. Sie kann dazu verwendet werden, um Brückenelemente aufzunehmen, welche sich auf einem externen Stapel von Brückenelementen befinden, so dass der Verlegearm nicht direkt von oben das Brückenelement aufnehmen kann. Dies war deswegen bislang problematisch, weil der Verlegearm nicht so weit in das oberste Brückenelement einfahren konnte, bis das zumeist im Mittelbereich des Verlegearms angeordnete Antriebselement, insbesondere das Antriebs-Triebstockrad, in den Triebstock eingreift. Aus diesem Grund musste das Brückenelement bislang beispielsweise mit einem Seil, das zwischen Verlegefahrzeug und Brückenelement befestigt wurde, um den notwendigen Weg nach vorne gezogen werden. Mit der Bremseinrichtung kann das Brückenelement nunmehr ohne zusätzliche Hilfsmittel aufgenommen werden. Das Fahrzeug wird hierbei an das Brückenelement herangefahren, bis die Bremseinrichtung in das Brükkenelement eingreift. Die Bremseinrichtung wird festgebremst und das Brückenelement wird über die gebremste Bremseinrichtung so weit nach vorne gezogen, bis das Antriebselement, insbesondere das Antriebs-Triebstockrad, in den Triebstock eingreifen kann. Besonders vorteilhaft ist es, mittels des Rotationsencoders die Einfahrtiefe des Verlegearms in das Brückenelement zu messen und im Fahrzeuginnenraum anzuzeigen.The braking device can perform other functions in addition to securing against slipping. It can be used to accommodate bridge elements located on an external stack of bridge elements so that the laying arm can not directly receive the bridge element from above. This was so far problematic because the laying arm could not retract so far in the upper bridge element until the usually arranged in the central region of the laying arm drive element, in particular the drive-Triebstockrad, engages in the drive train. For this reason, the bridge element so far had to be pulled by the necessary way forward, for example, with a rope that was attached between laying vehicle and bridge element. With the braking device, the bridge element can now be added without additional aids. The vehicle is moved up here to the bridge element until the braking device engages in the bridge element. The braking device is braked and the bridge element is pulled over the braked braking device so far forward until the drive element, in particular the drive Triebstockrad, can engage in the drive floor. It is particularly advantageous to measure the entry depth of the laying arm into the bridge element by means of the rotary encoder and to display it in the vehicle interior.

In einer weiteren vorteilhaften Ausgestaltung ist das Eingreifelement antreibbar ausgeführt. In diesem Fall kann sich die bremsende Wirkung der Bremseinrichtung bereits aus dem Antrieb ergeben, so dass keine zusätzlichen Bremselemente vorgesehen werden müssen. Die Bremswirkung kann sich ferner auch durch eine Selbsthemmung des Eingreifelements ergeben.In a further advantageous embodiment, the engaging element is designed to be drivable. In this case, the braking effect of the braking device may already result from the drive, so that no additional brake elements must be provided. The braking effect can also result from a self-locking of the engaging element.

Fig. 1 zeigt ein Verlegefahrzeug 1 mit einem Kettenantrieb, welches für den Transport von drei Brückenelementen 2, 2' und 2" ausgelegt ist. Das Fahrzeug 1 weist einen Verlegearm 3 auf, welcher mittels der Schwenkzylinder 4 und 5 in einer vertikalen Ebene verschwenkbar ist. Auf dem Verlegearm 3 ist ein Brückenelement 2 angeordnet, welches abgesetzt werden soll, um den Graben 10 zu überbrücken. Das vordere Ende des Brückenelements 2 ist bereits auf dem Boden abgesetzt. Fig. 1 shows a laying vehicle 1 with a chain drive, which is designed for the transport of three bridge elements 2, 2 'and 2 "The vehicle 1 has a laying arm 3, which by means of Swing cylinder 4 and 5 is pivotable in a vertical plane. On the laying arm 3, a bridge element 2 is arranged, which is to be discontinued in order to bridge the trench 10. The front end of the bridge element 2 is already set down on the ground.

Das Brückenelement 2 ist in Längsrichtung symmetrisch ausgeführt und weist auf jeder Seite einen Triebstock 6 auf. Das Brückenelement 2 wird auf dem Verlegearm 3 mittels zweier Antriebs-Triebstockräder 8 bewegt, welche mit den Triebstöcken 6 im Eingriff sind. Der Verlegearm 3 weist ferner im hinteren Bereich ein Hilfs-Triebstockrad 9 auf.The bridge element 2 is designed symmetrically in the longitudinal direction and has on each side of a lantern 6. The bridging element 2 is moved on the laying arm 3 by means of two drive trolley wheels 8, which are in engagement with the propulsions 6. The laying arm 3 also has an auxiliary drive wheel 9 in the rear area.

Der Bereich des Antriebs-Triebstockrads ist in Fig. 2 vergrößert dargestellt. Das Antriebs-Triebstockrad 8 befindet sich mit dem Triebstock 6 mit den Triebstockbolzen 16 im Eingriff.The range of the drive gantry wheel is in Fig. 2 shown enlarged. The drive Triebstockrad 8 is with the rack 6 with the rack bolts 16 in engagement.

Fig. 3 zeigt den vorderen Teil des Verlegearms 3 aus Fig. 1 mit dem Brückenelement 2 in einer vergrößerten Darstellung. Der Verlegearm weist mehrere Rollenelemente 11, 12 und 13 auf, auf welchen das Brückenelement 2 verschiebbar gelagert ist. Im Bereich des Absetzendes 14 ist als Eingreifelement ein Brems-Triebstockrad 15 angeordnet, welches ebenfalls in den Triebstock 6 eingreift und dessen Funktion im Folgenden erläutert wird. Fig. 3 shows the front part of the laying arm 3 Fig. 1 with the bridge element 2 in an enlarged view. The laying arm has a plurality of roller elements 11, 12 and 13, on which the bridge element 2 is slidably mounted. In the region of the settling end 14, a brake pinion wheel 15 is arranged as an engaging element, which also engages in the pinion 6 and its function will be explained below.

Fig. 4 zeigt das Verlegefahrzeug 1 in einer Stellung, in der das hintere, mit dem Verlegearm 3 in Verbindung stehende Ende des Brückenelements 2 bezüglich der in Fig. 1 gezeigten Darstellung weiter abgesenkt ist. Das Antriebs-Triebstockrad 8 hebt sich über den Triebstock 6, so dass diese nicht mehr im Eingriff sind, wobei dieser Effekt durch den stark abschüssigen zu überbrückenden Graben 10 verstärkt wird. Dies ist ebenfalls in einer vergrößerten Darstellung in Fig. 5 gezeigt. In der in Fig. 4 gezeigten Stellung kann die Bewegung des Brückenelements 2 nicht mehr durch das Antriebs-Triebstockrad 8 kontrolliert werden. Wenn keine zusätzliche Mittel vorgesehen wären, könnte das Brükkenelement 2 bei ungünstigen Bodenverhältnissen nach vorne durchrutschen. Um dies zu verhindern, ist das Brems-Triebstockrad 15 im Bereich des Absetzendes 14 des Verlegearms 3 angeordnet, welches sich auch in der in Fig. 4 gezeigten Stellung noch mit dem Triebstock 6 im Eingriff befindet. Während der Bewegung des Brückenelements 2 wird das Brems-Triebstockrad 15 gebremst. Fig. 4 shows the laying vehicle 1 in a position in which the rear, with the laying arm 3 in communication end of the bridge element 2 with respect to the in Fig. 1 shown representation is further lowered. The drive drive wheel 8 rises above the drive rod 6, so that they are no longer engaged, this effect being reinforced by the steeply sloping trench 10 to be bridged. This is also shown in an enlarged view in FIG Fig. 5 shown. In the in Fig. 4 shown position, the movement of the bridge element 2 can no longer be controlled by the drive Triebstockrad 8. If no additional means were provided, the bridging element 2 could slip forward in unfavorable ground conditions. To prevent this, the brake pinion 15 is disposed in the region of the settling end 14 of the laying arm 3, which is also in the in Fig. 4 shown position is still engaged with the rack 6 in engagement. During the movement of the bridge element 2, the brake drive wheel 15 is braked.

Das Brems-Triebstockrad 15 über dem aus vier einzelnen Rollen bestehenden Rollenelement 11 ist in Fig. 6 vergrößert dargestellt. Das Brems-Triebstockrad 15 ist über eine Getriebestufe 7 mit einer Bremsstufe 23 verbunden, welche das Bremsen des Brems-Triebstockrades leistet. An der Bremsstufe 23 ist ein Rotationsencoder 17 angeschlossen, welcher die Drehzahl der Bremsstufe misst und mittels einer angeschlossenen, nicht dargestellten Elektronik ein Fehlersignal für das Anhalten des Verlegevorgangs abgibt, falls das Brückenelement 2 während des Verlegens durchrutscht, weil die Bremswirkung des Brems-Triebstockrades 15 nicht ausgereicht hat.The Brems-Triebstockrad 15 on the existing of four individual roles roller element 11 is in Fig. 6 shown enlarged. The brake drive wheel 15 is connected via a gear stage 7 with a brake stage 23, which provides the braking of the brake drive wheel. At the brake stage 23, a rotary encoder 17 is connected, which measures the speed of the brake stage and emits an error signal for stopping the installation process by means of a connected, not shown electronics, if the bridge element 2 slips during installation, because the braking effect of the brake Triebstockrades 15th was not enough.

Das Zusammenwirken der Brems-Triebstockrades 15 mit dem Brückenelement 2 ist in Fig. 7 dargestellt, welche den Verlegearm 3 und das Brückenelement 2 aus Fig. 1 in einer Querschnittansicht zeigt. Das Brückenelement 2 ist spiegelsymmetrisch zu einer Spiegelebene in Längsrichtung aufgebaut und weist zwei Triebstöcke mit Triebstockbolzen 16 und 16' auf. In die Triebstöcke greifen von oben zwei Brems-Triebstockräder 15 und 15' ein. Das Brückenelement weist zwei Ausnehmungen 22 und 22' auf, welche als Führung dienen. Die Rollen der Rollengruppenelemente 11 und 11' laufen in den Ausnehmungen 22 und 22' und tragen das Brückenelement 2. Die Brems-Triebstockräder 15 und 15' sind über Wippenträger 19 und 19' jeweils mit einer Federdruck-Lamellenbremse 18 und 18' verbunden, welche die Brems-Triebstockräder abbremst.The interaction of the brake Triebstockrades 15 with the bridge element 2 is in Fig. 7 represented, which the laying arm 3 and the bridge element 2 from Fig. 1 in a cross-sectional view shows. The bridge element 2 is constructed mirror-symmetrically to a mirror plane in the longitudinal direction and has two drive blocks with Triebstockbolzen 16 and 16 'on. Into the batons engage from above two brake Triebstockräder 15 and 15 'a. The bridge element has two recesses 22 and 22 ', which serve as a guide. The rollers of the roller group elements 11 and 11 'run in the recesses 22nd and 22 'and carry the bridge element 2. The brake-Triebstockräder 15 and 15' are connected via rocker carrier 19 and 19 'each with a spring-loaded multi-disc brake 18 and 18', which brakes the brake-Triebstockräder.

Die Fig. 8 bis 10 zeigen den Ablauf beim Aufnehmen eines auf einem Anhänger 20 gelagerten Brückenelements 21. Auf dem Anhänger lagern insgesamt drei Brückenelemente 21, 21' und 21". Das Fahrzeug 1 wird zuerst an das Brückenelement 21 herangefahren, bis das Brems-Triebstockrad 15 des Verlegearms 3 in den Triebstock 24 des Brückenelements 21 eingreift (Fig. 8). Das Brems-Triebstockrad 15 wird festgebremst und das Brückenelement 21 wird über das gebremste Brems-Triebstockrad 15 nach vorne gezogen (Fig. 9). Das Brückenelement 21 wird so weit nach vorne gezogen, bis das Antriebs-Triebstockrad 8 in den Triebstock 6 des Brückenelements 21 eingreifen kann, so dass das Brückenelement vom Verlegearm 3 aufgenommen werden kann (Fig. 10).The Fig. 8 to 10 show the process of picking up a bridge element 21 mounted on a trailer 20. A total of three bridge elements 21, 21 'and 21 "are stored on the trailer the drive block 24 of the bridge element 21 engages ( Fig. 8 ). The brake drive wheel 15 is braked and the bridge element 21 is pulled forward over the braked brake drive wheel 15 (FIG. Fig. 9 ). The bridge element 21 is pulled so far forward until the drive Triebstockrad 8 can engage in the drive block 6 of the bridge element 21, so that the bridge element can be absorbed by the laying arm 3 ( Fig. 10 ).
