Description

Die Erfindung betrifft eine Baggeranbaufräse mit einer Anbaukonsole zum Anbau an einen beweglichen Trägerarm eines Baggers. Die Baggeranbaufräge umfasst mindestens einen Motor und zwei von diesem rotierend angetriebene Querschneidköpfe, die beidseitig der Längsachse der Anbaukonsole angebracht sind und zahlreiche Fräsmeißel tragen, wobei die Fräsmeißel jedes Querschneidkopfes bei dessen Drehung eine zylindrische Fräsmantelfläche beschreiben.The invention relates to a dredger with an attachment bracket for attachment to a movable support arm of an excavator. The excavator abutment comprises at least one motor and two of these rotationally driven cross-cutting heads, which are mounted on both sides of the longitudinal axis of the mounting bracket and carry a plurality of milling bits, the cutting tools of each cross-cutting head as it rotates describe a cylindrical Fräsmantelfläche.

Der Einsatzbereich für eine solche Baggeranbaufräse ist insbesondere der Straßenbau, Spezialtiefbau, Tunnel- oder Wasserbau. Dabei wird die Baggeranbaufräse z.B. zum Aufbrechen versiegelter Oberflächen aber auch zum Betonabbruch und zum Abbau bestimmter Erd- und Gesteinsschichten eingesetzt.The field of application for such a dredger is in particular road construction, special civil engineering, tunneling or hydraulic engineering. The excavator tiller is e.g. used for breaking up sealed surfaces but also for demolition of concrete and for the mining of certain layers of earth and rock.

Bekannt sind beispielsweise aus der DE 101 32 608 B4 oder EP 1 715 106 A1 Baggeranbaufräsen die als Querschneidkopffräsen ausgebildet sind und mit hartmetallbestückten Rundschaftmeißeln als Schneidwerkzeug ausgerüstet werden. Beim Einsatz dieses Fräsentyps, muss in der Regel die Fräse seitlich hin und her geschwenkt werden, um dadurch das Material zwischen den Schneidköpfen zu brechen. Der Nachteil dieser Fräsen ist, dass die Schneidbreite größer ausfällt als die eigentliche Breite des Fräskopfes, was sich im Kanalbau besonders unvorteilhaft erweist. Ein weiterer Nachteil besteht bei diesen Fräsen in der Belastung des Schwenkwerkes des Baggers, welches beim Fräsen ständig großen Torsions- und Scherkräften ausgesetzt wird.Are known, for example, from the DE 101 32 608 B4 or EP 1 715 106 A1 Excavator tillage mills which are designed as Querschneidkopffräsen and are equipped with carbide-tipped round shank bits as a cutting tool. When using this type of broom, the mill usually needs to be swung laterally to thereby break the material between the cutter heads. The disadvantage of these routers is that the cutting width is greater than the actual width of the milling head, which proves to be particularly unfavorable in sewer construction. Another disadvantage is in these milling in the load of the swing mechanism of the excavator, which is constantly exposed to large torsional and shear forces during milling.

Baggeranbaufräsen werden auch oft zum Abbau von weichen und mittelharten Gesteinen wie beispielsweise Kalksteine oder Gips eingesetzt. Dabei ist es besonders beim Gipsabbau wichtig, dass der Feinanteil im Fräsgut so gering wie möglich gehalten wird. Durch den Einsatz von Baggeranbaufräsen mit seitlichen Schneidköpfen, die an der Abbauwand verschwenkt werden, wird das vom vorderen Schneidkopf abgebrochene Material durch den nachfolgenden Schneidkopf unerwünscht weiter zerkleinert.Excavator tillage mills are also often used to break down soft and medium-hard rocks such as limestone or gypsum. It is particularly important in the case of plaster removal that the fines content in the milled material is kept as low as possible. Through the use of dredger mills with lateral cutting heads, which are pivoted on the mining wall, the broken off from the front cutting head material is undesirably further crushed by the subsequent cutting head.

Aus der DE 100 41 275 B4 ist ein Frässystem zum Anbau an hydraulische Trägergeräte bekannt, welches aus zwei oder mehreren über je einen Hydraulikmotor (3) gleichzeitig separat angetriebenen Anbaufräsen (1) gleichen oder unterschiedlichen Aufbaus mit gleichen oder unterschiedlichen Werkzeugträgern (6) besteht. Die einzelnen Anbaufräsen (1) sind über Verbindungskonsolen (8) auswechselbar nebeneinander, hintereinander oder winklig zueinander, auf gleicher oder unterschiedlicher Höhe angeordnet. Damit soll der Materialabbau frontal zum Trägergerät effizienter möglich sein. Allerdings ist dieses Frässystem aufwendig und beispielsweise für den Grabenbau wenig geeignet.From the DE 100 41 275 B4 a milling system for attachment to hydraulic carrier equipment is known, which consists of two or more simultaneously via a hydraulic motor (3) separately driven mounted milling (1) same or different structure with the same or different tool carriers (6). The individual mounted mills (1) are interchangeable via connecting brackets (8) side by side, one behind the other or at an angle to each other, arranged at the same or different height. Thus, the material removal frontal to the carrier device should be more efficient. However, this milling system is expensive and, for example, not very suitable for trench construction.

Aus der Druckschrift US 7,096,609 B2 ist ein so genannter Trencher bekannt, welcher mit einer Fräskette ausgestattet ist. Der Trencher umfasst vertikal zur Laufrichtung der Fräskette angebrachte Schneckenwellen, welche den abgetragenen Boden von dem ausgeschachteten Graben weg drücken. Ein Nachteil ist hier die beschränkte Einsetzbarkeit dieser Maschine. Für den großflächigen Materialabbau an einer Wand ist der Trencher ungeeignet. Durch seine hoch geführte Konstruktion wird der Trencher außerdem hohen mechanischen Beanspruchungen ausgesetzt. Dabei treten die Kräfte nicht nur in der Längsrichtung der umlaufenden Fräskette auf, sondern auch senkrecht zu der Kette, insbesondere wenn das Fräswerkzeug auf Hindernisse wie Steine oder gleichartiges auftrifft.From the publication US 7,096,609 B2 is a so-called Trencher known, which is equipped with a cutting chain. The trencher includes worm shafts mounted vertically to the direction of travel of the cutting chain, which push the removed soil away from the excavated trench. A disadvantage here is the limited usability of this machine. For large-scale material removal on a wall of the Trencher is unsuitable. The trencher is also exposed to high mechanical stresses due to its high-guided construction. The forces occur not only in the longitudinal direction of the rotating milling chain, but also vertically to the chain, especially if the milling tool hits obstacles such as stones or the like.

Die Aufgabe der Erfindung besteht darin, eine Baggeranbaufräse zum Anbau an einen beweglichen Trägerarm eines Baggers derart weiter zu entwickeln, dass es für unterschiedliche Fräs- und Schneidarbeiten einsetzbar ist, ohne dass dabei die Effizienz der einzelnen Arbeitssituationen wesentlich beeinträchtigt wird.The object of the invention is to further develop a dredger for attachment to a movable support arm of an excavator so that it can be used for different milling and cutting work, without thereby the efficiency of the individual work situations is significantly impaired.

Erfindungsgemäß wird diese Aufgabe durch eine Baggeranbaufräse gemäß dem beigefügten Anspruch 1 gelöst.According to the invention, this object is achieved by a dredger according to the appended claim 1.

Die erfindungsgemäße Baggeranbaufräse zum Anbau an einen beweglichen Trägerarm eines Baggers umfasst eine Anbaukonsole, an welcher rotierende Querschneidköpfe beidseitig zu der Längsachse der Anbaukonsole angebracht sind. Weiterhin umfasst die Baggeranbaufräse eine umlaufende Fräskette mit einer Laufrichtung, die parallel zur Längsachse der Anbaukonsole verläuft und die sich zwischen den beiden Querschneidköpfen erstreckt. An der Fräskette und den Querschneidköpfen sind zahlreiche Fräsmeißel angebracht, die bei einer Drehung der Querschneidköpfe eine zylindrische Fräsmantelfläche beschreiben. Die Fräsmeißel der Fräskette bilden am freiliegenden vorderen Ende der Fräskette eine halbzylindrische Manteloberfläche. Dabei liegt die vordere Umkehrlinie der Fräskette im Wesentlichen in einer die Fräsmantelflächen der beiden Querschneidköpfe tangierenden Ebene.The excavator tiller according to the invention for attachment to a movable carrier arm of an excavator comprises an attachment bracket, on which rotating transverse cutting heads are mounted on both sides of the longitudinal axis of the attachment bracket. Furthermore, the dredger comprises a rotating milling chain with a running direction which is parallel to the longitudinal axis of the attachment bracket and which extends between the two transverse cutting heads. Numerous milling bits are mounted on the milling chain and the transverse cutting heads, which describe a cylindrical milling surface area upon rotation of the transverse cutting heads. The milling bits of the milling chain form a semi-cylindrical mantle surface at the exposed front end of the milling chain. In this case, the front reversal line of the milling chain is located substantially in a plane tangent to the milling jacket surfaces of the two transverse cutting heads.

Die Berührungslinien der Fräsmeißel der Querschneidköpfe mit der zu fräsenden Oberfläche liegen damit ohne nennenswerte Lücke, die bei Geräten nach dem Stand der Technik durch die Breite der Anbaukonsole bestimmt ist, neben der Berührungslinie der Fräsmeißel der Fräskette. Zweckmäßigerweise liegen diese Berührungslinien auch in einer gemeinsamen Ebene.The contact lines of the cutting tools of the cross-cutting heads with the surface to be milled are thus without significant gap, which in devices according to the prior art by the width the mounting bracket is determined, next to the contact line of the milling cutter of the milling chain. Conveniently, these lines of contact are also in a common plane.

Damit besitzt die erfindungsgemäße Baggeranbaufräse den vorteil, dass ein seitliches verschwenken dieser Baggeranbaufräse nicht mehr notwendig ist, um flächig an einer Abbauwand Material abzutragen. Die Baggeranbaufräse wird oben an der Abbauwand angesetzt und arbeitet senkrecht nach unten. Mit der entsprechenden Bestückung der Querchneidköpfe und der Fräskette mit Werkzeugen lässt sich somit Gestein mit einer optimalen Körnung herstellen und der bewegliche Trägerarm des Baggers wird weniger belastet.Thus, the excavator tiller according to the invention has the advantage that a lateral pivoting this excavator tiller is no longer necessary to ablate material on a mining wall surface. The excavator tiller is attached to the top of the mining wall and works vertically downwards. With the appropriate equipping of the cross cutting heads and the milling chain with tools, it is thus possible to produce rock with optimum grain size, and the movable support arm of the excavator is subjected to less load.

Die Baggeranbaufräse umfasst in einer bevorzugten Ausführungsform zwei Mitnehmerritzel durch die der Antrieb der Fräskette erfolgt. Die jeweiligen Mitnehmettitzel sind zwischen der Fräskette und den benachbarten Querschneidköpfen angeordnet, wobei sie in Mitnehmerelemente der Fräskette als auch in den jeweils angrenzenden Querschneidkopf antreibend eingreifen. Die Kraftübertragung von den Mitnehmerritzeln auf die Fräskette erfolgt z.B. mittels Mitnehmerstiften, welche die Mitnehmerelemente der Fräskette bilden.In a preferred embodiment, the dredger has two driving pinions through which the drive of the cutting chain takes place. The respective Mitnehmettitzel are arranged between the cutting chain and the adjacent Querschneidköpfen, wherein they engage in driving elements of the cutting chain as well as in the respective adjacent transverse cutting head driving. The power transmission from the Mitnehmerritzeln on the milling chain is e.g. by means of driving pins, which form the driving elements of the milling chain.

In einer besonders bevorzugten Ausführungsform dieser Baggeranbaufräse ist die Verbindung zwischen den Mitnehmerritzel und den Querschneidköpfen lösbar, sodass die Querschneidköpfe von der Anbaukonsole abgenommen werden können, ohne dass der Antrieb der Fräskette beeinträchtigt wird. Durch diese Austauschbarkeit der Querschneidköpfe besteht die Möglichkeit, die Baggeranbaufräse für andere Anwendungszwecke umzugestalten und einzusetzen. Beispielsweise können Querschneidköpfe mit schmalerer Form gegen solche mit breiterer Form ausgetauscht werden.In a particularly preferred embodiment of this excavator tiller the connection between the driving pinion and the transverse cutting heads is detachable, so that the Querschneidköpfe can be removed from the mounting bracket without the drive of the cutting chain is affected. Through this interchangeability of Querschneidköpfe there is the possibility to remodel the excavator tiller for other applications and use. For example, cross-cutting heads of narrower shape can be replaced with those of wider shape.

Eine weitere Möglichkeit besteht darin, die Querschneidköpfe generell wegzulassen, um ausschließlich mit der Fräskette zu arbeiten. Dabei liegt der vorteil der erfindungsgemäßen Baggeranbaufräse darin, dass bei wechselnden Aufgaben auf der Baustelle diese modulare Baggeranbaufräse schnell und problemlos umgebaut werden kann, wodurch die Nutzung dieses Gerätes wirtschaftlicher und vielseitiger ist.Another possibility is to omit the cross-cutting heads in general in order to work exclusively with the milling chain. Here, the advantage of the excavator tiller according to the invention is that with changing tasks on site this modular excavator tiller can be quickly and easily converted, making the use of this device is more economical and versatile.

In einer weiteren Ausführungsform dieser Baggeranbaufräse wird die Fräskette verschleißarm in Längsrichtung zum Trägerarm über ein dort angeordnetes Getriebegehäuse geführt, vorzugsweise unter Zwischenschaltung einer Linearführungseinheit. Das Getriebegehäuse breitet sich in Längsrichtung zwischen den beiden Querschneidköpfen und der Anbaukonsole aus und umfasst ein Getriebe, welches zwischen dem Motor und den Querschneidköpfen liegt. Durch die Möglichkeit, dass die Länge des Gehäuses geändert werden kann, entsteht der Vorteil, dass die Tiefe des zu fräsenden Grabens regelbar ist und insgesamt eine größere Grabentiefe erlangt werden kann.In a further embodiment of this excavator cultivator, the milling chain is guided wear-resistant in the longitudinal direction of the support arm via a gear housing arranged there, preferably with the interposition of a linear guide unit. The gear housing extends longitudinally between the two transverse cutting heads and the mounting bracket and includes a gear which is located between the engine and the Querschneidköpfen. The possibility that the length of the housing can be changed, there is the advantage that the depth of the trench to be milled is adjustable and overall a greater trench depth can be obtained.

In einer bevorzugten Ausführungsform der Baggeranbaufräse ist ein einziger Motor zwischen den beiden Querschneidköpfen angeordnet, der von der Fräskette umlaufen wird. Dabei entfällt die Kraftübertragung auf die Fräskette über das Getriebe und der Antrieb erfolgt direkt, sowohl auf die Fräskette als auch auf die Querschneidköpfe, z.B. mit Hilfe der Mitnehmerritzel.In a preferred embodiment of the excavator tiller, a single motor is arranged between the two transverse cutting heads, which is circulated by the milling chain. The transmission of power to the milling chain via the gearbox is eliminated and the drive takes place directly, both on the cutting chain and on the transverse cutting heads, e.g. with the help of the driving pinion.

In einer abgewandelten Ausführungsform umfasst die Baggeranbaufräse mehrere Motoren, vorzugsweise Hydraulikmotoren, die jeweils einem Querschneidkopf zugeordnet sind. Der Antrieb der Fräskette erfolgt entsprechend über beide Motoren, welche in Längsrichtung und jeweils auf beiden Seiten des Getriebe- bzw. Motorgehäuses angeordnet sind.In a modified embodiment, the excavator tiller comprises a plurality of motors, preferably hydraulic motors, each associated with a transverse cutting head. The drive of the milling chain takes place correspondingly over both motors, which in Longitudinal direction and are arranged respectively on both sides of the transmission or motor housing.

Fig. 1 zeigt eine erste Ausführungsform eine erfindungsgemäßen Baggeranbaufräse mit einer Anbaukonsole zum Anbau an einen beweglichen Trägerarm eines Baggers in einer perspektivischen Darstellung. Die Baggeranbaufräse umfasst eine Fräskette 01 und zwei rotierende Querschneidköpfe 03, die an einer Anbaukonsole 02 angebracht sind. Die Anbaukonsole wird in an sich bekannter Weise an den Tragarm eines Baggers (nicht dargstellt) angeflanscht. Die Querschneidköpfe 03 sind an beiden Seiten der Anbaukonsole 02, bezogen auf deren Längsachse, befestigt. Die Fräskette 01 befindet sich zwischen den beiden rotierenden Querschneidköpfen 03 und verläuft parallel zur Längsachse der Anbaukonsole 02. Fig. 1 shows a first embodiment of an excavator tiller according to the invention with a mounting bracket for attachment to a movable support arm of an excavator in a perspective view. The dredger comprises a milling chain 01 and two rotating transverse cutting heads 03, which are mounted on a mounting bracket 02. The mounting bracket is flanged in a conventional manner to the support arm of an excavator (not dargstellt). The transverse cutting heads 03 are attached to both sides of the mounting bracket 02, based on the longitudinal axis thereof. The milling chain 01 is located between the two rotating transverse cutting heads 03 and extends parallel to the longitudinal axis of the mounting bracket 02.

An jedem der beiden Querschneidköpfe 03 und an der Fräskette 01 sind Fräsmeißel 04 angebracht, beispielsweise hartmetallbestückte Rundschaftmeißel, wobei diese auch mit anderen Schneidwerkzeugen, bestückt sein können. Während der Drehbewegung der Querschneidköpfe 03 um ihre Drehachse wird von den Fräsmeißeln 04 eine zylindrische Fräsmanteloberfläche beschrieben. Die Fräsmeißel 04 auf der Fräskette 01 sind in Laufrichtung verteilt, dabei beschreiben sie im Betrieb am freiliegenden vorderen Ende der Fräskette 01 eine halbzylindrische Fräsmanteloberfläche. Damit liegt die vordere Umkehrlinie der Fräskette 01 im Wesentlichen in einer Ebene mit der Ebene, die durch die Fräsmanteloberflächen der beiden Querschneidköpfe 03 definiert wird. Die Querschneidköpfe 03 und die Fräskette 01 bilden somit gemeinsam ein walzenähnliches Fräswerkzeug.At each of the two transverse cutting heads 03 and the milling chain 01 milling cutter 04 are mounted, such as carbide tipped round shank bit, which may be equipped with other cutting tools. During the rotational movement of the transverse cutting heads 03 about their axis of rotation of the Fräsmeißeln 04 describes a cylindrical Fräsmanteloberfläche. The milling bits 04 on the milling chain 01 are distributed in the running direction, while they describe in operation at the exposed front end of the milling chain 01 a semi-cylindrical Fräsmanteloberfläche. Thus, the front reversal line of the milling chain 01 lies substantially in a plane with the plane which is defined by the Fräsmanteloberflächen the two Querschneidköpfe 03. The cross-cutting heads 03 and the milling chain 01 thus together form a roller-like milling tool.

Die in Fig. 1 dargestellte Baggeranbaufräse umfasst zwei Mitnehmerritzel 05, durch die der Antrieb der Fräskette 01 und der beiden Querschneidköpfe 03 erfolgt. Die jeweiligen Mitnehmerritzel 5 sind zwischen der Fräskette 01 und dem benachbarten Querschneidkopf 03 angeordnet und werden über eine nicht dargestellte Antriebswelle angetrieben. Die Kraftübertragung von den Mitnehmerritzeln 05 auf die Fräskette 01 erfolgt mittels Mitnehmerstiften 07, die fest angebracht sind und sich an den den Querschneidköpfen zugewandten Seiten quer zur Laufrichtung der Fräskette 01 befinden. Durch das Eingreifen der Mitnehmerstifte 07 in dem drehbar angetriebenen Mitnehmerritzel 05 wird die Vorschubkraft auf die Fräskette 01 übertragen.In the Fig. 1 Excavator tiller shown comprises two driving pinion 05 through which the drive of the cutting chain 01 and the two transverse cutting heads 03 takes place. The respective driving pinion 5 are arranged between the cutting chain 01 and the adjacent transverse cutting head 03 and are driven by a drive shaft, not shown. The power transmission from the Mitnehmerritzeln 05 on the cutting chain 01 by means of driving pins 07, which are fixedly mounted and are located at the transverse cutting heads facing sides transverse to the direction of the milling chain 01. By the engagement of the driving pins 07 in the rotatably driven driving pinion 05, the feed force is transmitted to the milling chain 01.

In Fig. 1 ist eine Ausführungsform dargestellt, in welcher zwischen den Querschneidköpfen 03 und den Mitnehmerritzeln 07 eine dauerhafte Verbindung vorhanden ist. Die Querschneidköpfe 03 sind beispielsweise durch Schweißen an der Anbaukonsole 02 befestigt.In Fig. 1 an embodiment is shown in which between the transverse cutting heads 03 and the Mitnehmerritzeln 07 a permanent connection is present. The transverse cutting heads 03 are fastened to the mounting bracket 02 by welding, for example.

Die Fräskette 01 wird über ein Getriebegehäuse 09 verschleißarm geführt, welches in Längsrichtung zum Trägerarm verläuft und sich ausgehend von der Anbaukonsole 02 bis zwischen die beiden Querschneidköpfe 03 erstreckt. Auf dem Getriebegehäuse ist dazu eine Linearführungseinheit angebracht. Die Umlenkung der Fräskette 01 wird mittels einer nicht sichtbaren Umlenkrolle realisiert. Diese Ausführungsform der Baggeranbaufräse weist weiterhin ein nicht dargestelltes Getriebe und zwei seitlich angeflanschte Motoren 11 auf, welche für den, Antrieb sowohl der Fräskette 01 als auch der beiden Querschneidköpfe 03 zur Verfügung stehen. Das Untersetzungsgetriebe befindet sich zwischen den Querschneidköpfen 03 und der Anbaukonsole 02 und wird von der Fräskette 01 umlaufen.The milling chain 01 is guided wear-resistant via a gear housing 09, which extends in the longitudinal direction of the support arm and extending from the mounting bracket 02 to between the two transverse cutting heads 03. On the gear housing for a linear guide unit is attached. The deflection of the milling chain 01 is realized by means of a non-visible pulley. This embodiment of the excavator tiller also has a gear, not shown, and two laterally flanged motors 11, which are available for driving both the milling chain 01 and the two transverse cutting heads 03. The reduction gear is located between the transverse cutting heads 03 and the mounting bracket 02 and is circulated by the milling chain 01.

Der Antrieb der Fräskette 01 und der beiden Querschneidköpfe 03 erfolgt mittels der Motoren 11, welche vorzugsweise Hydraulikmotoren sind. Jedem der Querschneidköpfe 03 ist einer der Motoren 11 zugeordnet, die sich zwischen dem Getriebe und der Anbaukonsole 02 an beiden Seiten des Getriebegehäuses 09 befinden. Der Antrieb der Fräskette erfolgt entsprechend über beide Motoren gleichzeitig.The drive of the milling chain 01 and the two transverse cutting heads 03 by means of the motors 11, which are preferably hydraulic motors. Each of the transverse cutting heads 03 is associated with one of the motors 11, which are located between the transmission and the mounting bracket 02 on both sides of the transmission housing 09. The drive of the milling chain takes place simultaneously via both motors.

In Fig. 2 ist eine zweite Ausführungsform der Baggeranbaufräse dargestellt, welches die wesentlichen Elemente der zuvor beschriebenen Ausführungsform ebenfalls enthält.In Fig. 2 a second embodiment of the excavator tiller is shown, which also contains the essential elements of the embodiment described above.

Die Besonderheit dieser Ausführungsform ist, dass der Antrieb der Fräskette 01 über einen Motor erfolgt, vorzugsweise einen Hydraulikmotor, der ohne Untersetzungsgetriebe an die Fräskette 01 gekoppelt ist. Der Motor ist zwischen den beiden Querschneidköpfen 03 ungeordnet und wird von der Fräskette 01 umlaufen. Sowohl die Fräskette 01 als auch die Querschneidköpfe 03 werden von dem langsam laufenden Motor angetrieben.The peculiarity of this embodiment is that the drive of the cutting chain 01 takes place via a motor, preferably a hydraulic motor, without reduction gear to the Milling chain 01 is coupled. The motor is disordered between the two transverse cutting heads 03 and is circulated by the milling chain 01. Both the milling chain 01 and the transverse cutting heads 03 are driven by the slow-running motor.

Die Querschneidköpfe 03 sind bei dieser Ausführungsform mit den Mitnehmerritzeln 05 lösbar verbunden, wodurch die Querschneidköpfe 03 von der Anbaukonsole 01 abnehmbar sind, ohne dass der Antrieb der Fräskette 01 beeinträchtigt wird.The cross cutting heads 03 are releasably connected in this embodiment with the Mitnehmerritzeln 05, whereby the Querschneidköpfe 03 are removable from the mounting bracket 01 without the drive of the milling chain 01 is affected.
