Definitions
- the present invention relates to an apparatus and arrangement for tracking cross-country ski trails, and to a method for preparing cross-country ski trails and a snow groomer having a device or arrangement for tracking cross-country trails and for practicing a method of tracking cross-country trails according to the preambles of the independent claims.
- Cross-country ski trails include two individual lanes at a desired distance, which can steer and receive the cross-country skis in predetermined lanes. Such tracks are tracked by means of cross-country trailers to provide a safe and comfortable trail for cross-country skiers.
- a cross-country track device which, for example, is pulled through the snow by a harness and creates a corresponding cross-country track.
- the device comprises a doctor blade, which presses the snow in a first step and gives it the well-known groove structure.
- the trailers include toe bodies that push a first track into the fresh snow.
- Arranged behind the Vorspurterrorism are knives that tear the track to the desired level.
- Behind the knives a squeegee blade is arranged, which presses in the track fallen snow again.
- track bodies which press any fallen back into the track snow to the track and give the track the final shape.
- Such a device is expensive to manufacture and requires different settings depending on the snow conditions.
- DE 34 20 210 is also a device for tracking or grading cross-country ski trails has become known.
- This device is also pulled over the snow, where it is essentially carried by a front in the direction of travel floating body. Behind the float is a tearing device, which loosens and breaks up the snow over the entire width of the track device. Following the tearing device is a tiller, which also mills and shreds the snow over the entire depth. The snow is so deeply torn open and milled that in the now loose snow a cross-country track can be pressed. The tiller is driven by a separate unit. Following the router are track plates, which is preceded by a slide, and press the track in the now prepared snow.
- This track-type tracker requires a high drive power and, due to the extensive mechanical processing of the snow, a high tractive power of the prestressed traction device.
- a track device is to be made available, which is easy to use, requires little or no additional energy and improves the quality of the trail.
- the device comprises one or more tearing devices for tearing open the substrate as well as a milling device.
- the milling device is arranged in a direction of travel of the device in front of the track drawing body and after the tearing device.
- Each tracking body is associated with a tearing device which tears open only a substantially corresponding to the width of the track drawing body area.
- the tearing device is arranged in a direction of travel of the device in front of the respective track drawing body.
- the individual assignment of a tearing device to the individual track bodies allows punctiform tearing of the substrate at the point where the cross-country track is drawn with the track drawing bodies.
- the spaces between the tearing devices remain free.
- the precise and precise tearing of the substrate reduces the energy expenditure that has to be introduced into the device.
- the ground is only partially torn open. Thus, the device is less prone to different textures of the substrate.
- the ground in this case, for example, loose snow or already pressed snow, can be processed evenly.
- the device is also particularly suitable for processing very hard snow or ice.
- An external dimension of the tearing device also relates to the part or area of the tearing device which can engage or engage in the ground.
- the device comprises a plurality of track drawing bodies with associated tearing devices
- a gap between the individual tearing devices is preferably free, so that the ground, which is located between the tearing devices and subsequently between the individual cross-country tracks, is not processed. The energy expenditure for tearing and traces is thus minimized.
- the track drawing bodies are preferably arranged in pairs next to one another.
- the associated tear-open devices are also arranged in pairs in a direction of travel of the device in front of the respective track drawing body.
- a two-piece cross-country track which corresponds to standards common in ski sports can be produced in one step.
- the device is designed such that the ratio of an outer dimension of the tearing device transverse to the cross-country track to an outer dimension of the track drawing body 2: 1 and preferably [1.5: 1] and more preferably [1,1: 1] does not exceed.
- the outer dimension of the tear-open device is essentially understood to mean the dimension of the torn-open area.
- the tearing device of the device preferably has cutting blades.
- Cutting knives are capable of cutting the ground, reducing the resistance of the device as it moves through the ground and thus also reducing the energy required to pull the device.
- Cutting knives may preferably be interchangeable. For example, different cutting blades with different cutting geometries are conceivable for different ratios of the background. Also, this facilitates the maintenance, since scuffed or damaged cutting blades can be easily and quickly replaced.
- the milling device may have a milling drum.
- the milling device has an engagement depth which does not exceed a track depth of the cross-country track and is preferably at most 50% and preferably at most 30% of the track depth.
- the engagement depth is 10% to 15% of the track depth. This also makes it possible to reduce the energy input required. Depending on the condition of the subsoil, and especially on already existing cross-country tracks, which are nachgespurt, it is thus possible and it is sufficient to edit the track only in the area of the surface of the substrate.
- the milling device has an outer dimension transverse to the cross-country track, which exceeds an outer dimension of the track drawing body transversely to the cross-country track and in particular an outer dimension of the tearing device transversely to the cross-country track, preferably by at least 5% and more preferably by at least 10%.
- the cross-country ski, or the ground in which the cross-country track is located can be selectively processed in the area that is necessary for an accurate execution of the trail of tracks.
- Such an outside dimension is particularly advantageous, since the over-milled surface covers both the area of the track drawing body and the area which was torn open by the tearing device.

- a homogeneous cross-country trail can be made.
- a common milling device is associated with a plurality of tracking bodies and has an outer dimension transverse to the cross-country track, which has a common dimension of SpurziehMech transversely to the cross-country track and in particular a common dimension of the tearing devices transversely to the cross-country track exceeds.
- this dimension exceeds the aforementioned dimensions by at least 5% and more preferably by at least 10%.
- the device may be pulled by a towing vehicle or arranged behind a towing vehicle in the direction of travel.
- the towing vehicle leaves tracks in the underground.
- Towing vehicles are manufactured in different sizes and have different widths.
- towing vehicles are 2.5m, 2.8m, 3.2m, 4.3m or 4.5m wide and leave a correspondingly wide lane.
- the outer dimension of the common milling device is greater than an outer dimension of the lane. Lanes of the towing vehicle can thus also be milled, whereby a uniform surface can be obtained.
- a common outer dimension of the tearing devices transversely to the cross-country track exceeds a common outer dimension of the track drawing body transversely to the cross-country track.
- the common outer dimension of the tearing devices exceeds the common outer dimension of the track drawing bodies by at least 5%, preferably by at least 10%.
- the milling device of the arrangement may have an engagement depth which does not exceed a track depth of the cross-country track and is preferably at most 50% and preferably at most 30% of the track depth. Particularly preferably, the engagement depth is 10% to 15% of the track depth.
- the substrate is torn open by means of the tearing device associated with the respective track drawing body in a region which corresponds only substantially to the width of the track drawing body.
- the torn-open area does not exceed a ratio of 2: 1 and preferably of 1.5: 1 and more preferably of 1.1: 1 to an outside dimension of the cross-country track transversely to the cross-country track.
- This method enables a precise introduction of the energy in the area of the later cross-country track and thus reduces the total energy expenditure that must be used to trace cross-country ski trails.
- the ground is milled to an engagement depth that does not exceed a track depth of the cross-country track and is preferably at most 50% and more preferably at most 30% of the track depth.

Eine derartige Vorrichtung ist aufwendig zu fertigen und benötigt je nach Schneeverhältnissen unterschiedliche Einstellungen.Such a device is expensive to manufacture and requires different settings depending on the snow conditions.
Mit der
Dieses Loipenspurgerät benötigt eine hohe Antriebsleistung sowie durch die umfangreiche mechanische Bearbeitung des Schnees eine hohe Zugleistung des vorgespannten Zuggerätes.This track-type tracker requires a high drive power and, due to the extensive mechanical processing of the snow, a high tractive power of the prestressed traction device.

In particular, a track device is to be made available, which is easy to use, requires little or no additional energy and improves the quality of the trail.
Diese Aufgabe wird durch die in den unabhängigen Patentansprüchen definierten Vorrichtungen und Verfahren gelöst.This object is achieved by the devices and methods defined in the independent patent claims.
Weitere Ausführungsformen ergeben sich aus den abhängigen Patentansprüchen.Further embodiments emerge from the dependent claims.
Eine erfindungsgemässe Vorrichtung zum Spuren von Langlaufloipen umfasst zumindest einen oder mehrere Spurziehkörper zum Spuren einer Langlaufspur. Die Vorrichtung umfasst einen oder mehrere Aufreissvorrichtungen zum Aufreissen von Untergrund sowie eine Fräsvorrichtung. Die Fräsvorrichtung ist in einer Fahrtrichtung der Vorrichtung vor dem Spurziehkörper und nach der Aufreissvorrichtung angeordnet. Jedem Spurziehkörper ist eine Aufreissvorrichtung zugeordnet, welche nur einen im Wesentlichen der Breite des Spurziehkörpers entsprechenden Bereich aufreisst. Somit ist die Aufreissvorrichtung in einer Fahrtrichtung der Vorrichtung vor dem jeweiligen Spurziehkörper angeordnet.An apparatus according to the invention for tracking cross-country ski tracks comprises at least one or more track drawing bodies for tracking a cross-country track. The device comprises one or more tearing devices for tearing open the substrate as well as a milling device. The milling device is arranged in a direction of travel of the device in front of the track drawing body and after the tearing device. Each tracking body is associated with a tearing device which tears open only a substantially corresponding to the width of the track drawing body area. Thus, the tearing device is arranged in a direction of travel of the device in front of the respective track drawing body.
Die individuelle Zuordnung einer Aufreissvorrichtung zu den einzelnen Spurkörpern ermöglicht ein punktuelles Aufreissen des Untergrundes an der Stelle, an der die Langlaufspur mit den Spurziehkörpern gezogen wird. Die Zwischenräume zwischen den einzelnen Aufreissvorrichtungen bleiben frei. Das punktgenaue und präzise Aufreissen des Untergrundes reduziert den Energieaufwand, der in die Vorrichtung eingebracht werden muss. Der Untergrund wird nur partiell aufgerissen. Somit ist die Vorrichtung weniger anfällig auf unterschiedliche Beschaffenheiten des Untergrundes. Der Untergrund, vorliegend beispielsweise Lockerschnee oder bereits angepresster Schnee, kann gleichmässig bearbeitet werden. Die Vorrichtung eignet sich insbesondere ebenfalls zum Bearbeiten von sehr hartem Schnee oder Eis.The individual assignment of a tearing device to the individual track bodies allows punctiform tearing of the substrate at the point where the cross-country track is drawn with the track drawing bodies. The spaces between the tearing devices remain free. The precise and precise tearing of the substrate reduces the energy expenditure that has to be introduced into the device. The ground is only partially torn open. Thus, the device is less prone to different textures of the substrate. The ground, in this case, for example, loose snow or already pressed snow, can be processed evenly. The device is also particularly suitable for processing very hard snow or ice.
Hier und im Folgenden wird unter Aufreissvorrichtung der Teil einer Vorrichtung verstanden, welche in den Untergrund eingreift oder eingreifen kann und den Untergrund in einem gewünschten Bereich aufreisst. Eine Aussenabmessung der Aufreissvorrichtung bezieht sich ebenfalls auf den Teil oder Bereich der Aufreissvorrichtung, welcher in den Untergrund eingreift oder eingreifen kann.Here and below is understood by tearing the part of a device which engages or can engage in the ground and the substrate in a desired Area breaks up. An external dimension of the tearing device also relates to the part or area of the tearing device which can engage or engage in the ground.
Umfasst die Vorrichtung mehrere Spurziehkörper mit zugehörigen Aufreissvorrichtungen, so ist ein Zwischenraum zwischen den einzelnen Aufreissvorrichtungen vorzugsweise frei, so dass der Untergrund, welcher sich zwischen den Aufreissvorrichtungen und in der Folge zwischen den einzelnen Langlaufspuren befindet, nicht bearbeitet wird. Der Energieaufwand zum Aufreissen und Spuren wird somit minimiert.If the device comprises a plurality of track drawing bodies with associated tearing devices, then a gap between the individual tearing devices is preferably free, so that the ground, which is located between the tearing devices and subsequently between the individual cross-country tracks, is not processed. The energy expenditure for tearing and traces is thus minimized.
Bei einer Vorrichtung mit mehreren Spurziehkörpern sind die Spurziehkörper bevorzugt paarweise nebeneinander angeordnet. Die zugehörigen Aufreissvorrichtungen sind ebenfalls paarweise in einer Fahrtrichtung der Vorrichtung vor dem jeweiligen Spurziehkörper angeordnet.In a device having a plurality of tracking bodies, the track drawing bodies are preferably arranged in pairs next to one another. The associated tear-open devices are also arranged in pairs in a direction of travel of the device in front of the respective track drawing body.
Somit kann eine zweiteilige Langlaufspur, die im Skisport gängigen Normen entspricht in einem Arbeitsschritt hergestellt werden.Thus, a two-piece cross-country track, which corresponds to standards common in ski sports can be produced in one step.
Vorzugsweise ist die Vorrichtung derart gestaltet, dass das Verhältnis einer Aussenabmessung der Aufreissvorrichtung quer zur Langlaufspur zu einer Aussenabmessung der Spurziehkörper 2:1 und vorzugsweise [1,5:1] und besonders bevorzugt [1,1:1] nicht übersteigt. Als Aussenabmessung der Aufreissvorrichtung wird im Wesentlichen die Abmessung des aufgerissenen Bereiches verstanden.Preferably, the device is designed such that the ratio of an outer dimension of the tearing device transverse to the cross-country track to an outer dimension of the track drawing body 2: 1 and preferably [1.5: 1] and more preferably [1,1: 1] does not exceed. The outer dimension of the tear-open device is essentially understood to mean the dimension of the torn-open area.
Durch diese Verhältnisse wird sichergestellt, dass der Untergrund nur im Bereich der Spurziehkörper aufgerissen wird. Eine unnötige Bearbeitung des Untergrundes wird verhindert.These conditions ensure that the substrate is torn open only in the area of the track drawing body. An unnecessary processing of the substrate is prevented.
Bevorzugt weist die Aufreissvorrichtung der Vorrichtung Schneidmesser auf.The tearing device of the device preferably has cutting blades.
Schneidmesser vermögen den Untergrund zu schneiden, was den Widerstand der Vorrichtung beim Ziehen durch den Untergrund verringert und somit ebenfalls den Energieaufwand zum Ziehen der Vorrichtung vermindert.Cutting knives are capable of cutting the ground, reducing the resistance of the device as it moves through the ground and thus also reducing the energy required to pull the device.
Schneidmesser können bevorzugt auswechselbar sein. So sind beispielsweise für unterschiedliche Verhältnisse des Untergrundes unterschiedliche Schneidmesser mit unterschiedlichen Schneidgeometrien vorstellbar. Ebenfalls erleichtert dies die Wartung, da abgewetzte oder beschädigte Schneidmesser einfach und schnell ausgetauscht werden können.Cutting knives may preferably be interchangeable. For example, different cutting blades with different cutting geometries are conceivable for different ratios of the background. Also, this facilitates the maintenance, since scuffed or damaged cutting blades can be easily and quickly replaced.
Die Fräsvorrichtung kann eine Fräswalze aufweisen.The milling device may have a milling drum.
Dies ermöglicht eine gleichmässige Bearbeitung des aufgerissenen Untergrundes.This allows a uniform processing of the torn underground.
Vorzugsweise weist die Fräsvorrichtung eine Eingreiftiefe auf, welche eine Spurtiefe der Langlaufspur nicht übersteigt und vorzugsweise maximal 50% und bevorzugt maximal 30% der Spurtiefe beträgt. Besonders bevorzugt beträgt die Eingreiftiefe 10% bis 15% der Spurtiefe. Dies ermöglicht ebenfalls, den einzubringenden Energieaufwand zu reduzieren. Je nach Beschaffenheit des Untergrundes, und insbesondere bei bereits bestehenden Langlaufloipen, die nachgespurt werden, ist es somit möglich und genügt es, die Spur nur im Bereich der Oberfläche des Untergrundes zu bearbeiten.Preferably, the milling device has an engagement depth which does not exceed a track depth of the cross-country track and is preferably at most 50% and preferably at most 30% of the track depth. Particularly preferably, the engagement depth is 10% to 15% of the track depth. This also makes it possible to reduce the energy input required. Depending on the condition of the subsoil, and especially on already existing cross-country tracks, which are nachgespurt, it is thus possible and it is sufficient to edit the track only in the area of the surface of the substrate.
Vorzugsweise weist die Fräsvorrichtung eine Aussenabmessung quer zur Langlaufspur auf, welche eine Aussenabmessung des Spurziehkörpers quer zur Langlaufspur und insbesondere eine Aussenabmessung der Aufreissvorrichtung quer zur Langlaufspur übersteigt, vorzugsweise um mindestens 5% und besonders bevorzugt um mindestens 10%.Preferably, the milling device has an outer dimension transverse to the cross-country track, which exceeds an outer dimension of the track drawing body transversely to the cross-country track and in particular an outer dimension of the tearing device transversely to the cross-country track, preferably by at least 5% and more preferably by at least 10%.
Somit kann die Langlaufloipe, oder der Untergrund in welchem sich die Langlaufspur befindet, punktuell in dem Bereich bearbeitet werden, der für eine exakte Ausführung der Loipenspur nötig ist. Besonders vorteilhaft ist eine derartige Aussenabmessung, da die überfräste Oberfläche sowohl den Bereich des Spurziehkörpers als auch den Bereich, der mit der Aufreissvorrichtung aufgerissen wurde, überdeckt.Thus, the cross-country ski, or the ground in which the cross-country track is located, can be selectively processed in the area that is necessary for an accurate execution of the trail of tracks. Such an outside dimension is particularly advantageous, since the over-milled surface covers both the area of the track drawing body and the area which was torn open by the tearing device.
Vorzugsweise weist die Vorrichtung zum Spuren von Langlaufloipen genau eine Fräsvorrichtung auf, welche zwischen Spurziehkörpern und Aufreissvorrichtungen angeordnet ist. Bevorzugt ist die Aufreissvorrichtung in einer Fahrtrichtung der Anordnung vor dem jeweiligen Spurziehkörper angeordnet.Preferably, the device for tracking cross-country trails exactly on a milling device, which is arranged between Spurziehkörpern and tearing devices. Preferably, the tearing device is arranged in a direction of travel of the arrangement in front of the respective track drawing body.
Die Anordnung mit einer einzigen Fräsvorrichtung vereinfacht den Aufbau der Anordnung. Ausserdem kann die Oberfläche des Untergrundes über die Breite von mehreren Spurziehkörpern gleichmässig überfräst werden. Somit kann eine homogene Langlaufloipe hergestellt werden.The arrangement with a single milling device simplifies the structure of the arrangement. In addition, the surface of the substrate over the width of several Spurziehkörpern be milled evenly. Thus, a homogeneous cross-country trail can be made.
Vorzugsweise ist eine gemeinsame Fräsvorrichtung mehreren Spurziehkörpern zugeordnet und weist eine Aussenabmessung quer zur Langlaufspur auf, welche eine gemeinsame Dimension der Spurziehkörper quer zur Langlaufspur und insbesondere eine gemeinsame Dimension der Aufreissvorrichtungen quer zur Langlaufspur übersteigt. Vorzugsweise übersteigt diese Abmessung die vorgenannten Dimensionen um mindestens 5% und weiter bevorzugt um mindestens 10%.Preferably, a common milling device is associated with a plurality of tracking bodies and has an outer dimension transverse to the cross-country track, which has a common dimension of Spurziehkörper transversely to the cross-country track and in particular a common dimension of the tearing devices transversely to the cross-country track exceeds. Preferably, this dimension exceeds the aforementioned dimensions by at least 5% and more preferably by at least 10%.
Somit ist gewährleistet, dass beim Spuren von mehreren Langlaufspuren eine gleichmässige Oberfläche erhaltbar ist.This ensures that a uniform surface can be obtained when several cross-country tracks are being tracked.
Die Vorrichtung kann von einem Zugfahrzeug gezogen sein oder in Fahrtrichtung hinter einem Zugfahrzeug angeordnet sein. Typischerweise hinterlässt das Zugfahrzeug Fahrspuren im Untergrund. Zugfahrzeuge werden in unterschiedlichen Grössen hergestellt und weisen unterschiedliche Breiten auf. Typischerweise sind Zugfahrzeuge 2,5m, 2,8m, 3,2m, 4,3m oder 4,5m breit und hinterlassen eine entsprechend breite Fahrspur. Vorzugsweise ist die Aussenabmessung der gemeinsamen Fräsvorrichtung grösser als eine Aussenabmessung der Fahrspur. Fahrspuren des Zugfahrzeuges können somit ebenfalls überfräst werden, wodurch eine gleichmässige Oberfläche erhaltbar ist.The device may be pulled by a towing vehicle or arranged behind a towing vehicle in the direction of travel. Typically, the towing vehicle leaves tracks in the underground. Towing vehicles are manufactured in different sizes and have different widths. Typically, towing vehicles are 2.5m, 2.8m, 3.2m, 4.3m or 4.5m wide and leave a correspondingly wide lane. Preferably, the outer dimension of the common milling device is greater than an outer dimension of the lane. Lanes of the towing vehicle can thus also be milled, whereby a uniform surface can be obtained.
Vorzugsweise übersteigt eine gemeinsame Aussenabmessung der Aufreissvorrichtungen quer zur Langlaufspur eine gemeinsame Aussenabmessung der Spurziehkörper quer zur Langlaufspur. Bevorzugt übersteigt die gemeinsame Aussenabmessung der Aufreissvorrichtungen die gemeinsame Aussenabmessung der Spurziehkörper um mindestens 5%, bevorzugt um mindestens 10%.Preferably, a common outer dimension of the tearing devices transversely to the cross-country track exceeds a common outer dimension of the track drawing body transversely to the cross-country track. Preferably, the common outer dimension of the tearing devices exceeds the common outer dimension of the track drawing bodies by at least 5%, preferably by at least 10%.
Somit bearbeitet die Aufreissvorrichtung der Untergrund nur in dem Bereich, in dem die Spurziehkörper die Langlaufspur ziehen. Der Energieeintrag, der für die Vorrichtung aufgebracht und das Spuren der Langlaufspur aufgebracht werden muss, ist reduziert. Die Fräsvorrichtung der Anordnung kann eine Eingreiftiefe aufweisen, welche eine Spurtiefe der Langlaufspur nicht übersteigt und vorzugsweise maximal 50% und bevorzugt maximal 30% der Spurtiefe beträgt. Besonders bevorzugt beträgt die Eingreiftiefe 10% bis 15% der Spurtiefe.Thus, the tearing device processes the ground only in the area in which the track drawing body pull the cross-country track. The energy input that must be applied to the device and the traces of the cross-country track must be applied is reduced. The milling device of the arrangement may have an engagement depth which does not exceed a track depth of the cross-country track and is preferably at most 50% and preferably at most 30% of the track depth. Particularly preferably, the engagement depth is 10% to 15% of the track depth.
Dies erlaubt eine oberflächliche Bearbeitung des Untergrundes und reduziert ebenfalls den nötigen Energieeintrag. Zusätzlich bleibt unterhalb der überfrästen Oberfläche ein festes Bett bestehen, welche der Stabilität der Langlaufloipe zuträglich ist und die Haltbarkeit der Langlaufloipe verlängert.This allows a superficial treatment of the substrate and also reduces the necessary energy input. In addition, a fixed bed remains below the milled surface, which contributes to the stability of the cross-country ski trail and extends the durability of the cross-country ski trail.
Ein weiterer Aspekt der Erfindung betrifft ein Verfahren zum Präparieren von Langlaufloipen mit einer Vorrichtung die eine Fräsvorrichtung, einen oder mehrere Spurziehkörper und einen oder mehrere Aufreissvorrichtungen umfasst und vorzugsweise mit einer Vorrichtung wie vorliegend beschrieben. Das Verfahren umfasst die Schritte:
- Aufreissen eines Untergrundes
- Überfräsen des aufgerissenen Untergrundes und
- Spuren des Untergrundes.
- Ripping open a subsoil
- Overmilling the torn underground and
- Traces of the underground.
Der Untergrund wird mittels der dem jeweiligen Spurziekörper zugeordneten Aufreissvorrichtung in einem Bereich aufgerissen, welcher nur im Wesentlichen der Breite des Spurziehkörpers entspricht. Vorzugsweise übersteigt der aufgerissene Bereich ein Verhältnis von 2:1 und vorzugsweise von 1,5:1 und besonders bevorzugt von 1,1:1 zu einer Aussenabmessung der Langlaufspur quer zur Langlaufspur nicht.The substrate is torn open by means of the tearing device associated with the respective track drawing body in a region which corresponds only substantially to the width of the track drawing body. Preferably, the torn-open area does not exceed a ratio of 2: 1 and preferably of 1.5: 1 and more preferably of 1.1: 1 to an outside dimension of the cross-country track transversely to the cross-country track.
Dieses Verfahren ermöglicht ein punktgenaues Einbringen der Energie im Bereich der späteren Langlaufspur und reduziert somit den Gesamtenergieaufwand, der zum Spuren von Langlaufloipen verwendet werden muss.This method enables a precise introduction of the energy in the area of the later cross-country track and thus reduces the total energy expenditure that must be used to trace cross-country ski trails.
Vorzugsweise wird der Untergrund bis zu einer Eingreiftiefe überfräst, die eine Spurtiefe der Langlaufspur nicht übersteigt und vorzugsweise maximal 50% und besonders bevorzugt maximal 30% der Spurtiefe beträgt. Besonders bevorzugt beträgt die Eingreiftiefe 10% bis 15% der Spurtiefe.Preferably, the ground is milled to an engagement depth that does not exceed a track depth of the cross-country track and is preferably at most 50% and more preferably at most 30% of the track depth. Particularly preferably, the engagement depth is 10% to 15% of the track depth.
Dies ermöglicht ebenfalls ein gleichmässiges Bearbeiten des Untergrundes und reduziert den Energieaufwand und begünstigt den Aufbau der Langlaufloipe, wie vorliegend erwähnt.This also allows a uniform processing of the substrate and reduces the energy consumption and favors the construction of the cross-country ski trail, as mentioned herein.
Bevorzugt wird der Untergrund in einem Bereich überfräst, der eine Aussenabmessung der Langlaufspur quer zur Langlaufspur und insbesondere eine Aussenabmessung des aufgerissenen Bereiches übersteigt, vorzugsweise um mindestens 5% und besonders bevorzugt um mindestens 10%.Preferably, the substrate is milled in an area which exceeds an outer dimension of the cross-country track transversely to the cross-country track and in particular an outer dimension of the torn-open area, preferably by at least 5% and more preferably by at least 10%.
Eine gleichmässige Ausgestaltung der Spur, welche einen qualitativ hochstehenden optischen Eindruck hinterlässt, wird somit erreicht. Der Aufgerissene Untergrund wird somit bearbeitet und erhält eine gleichmässige Struktur.A uniform configuration of the track, which leaves a high-quality visual impression, is thus achieved. The torn underground is thus processed and maintains a uniform structure.
Ein weiterer Aspekt der Erfindung betrifft ein Zugfahrzeug und insbesondere ein Pistenfahrzeug mit einer Anordnung oder einer Vorrichtung wie vorliegend beschrieben.Another aspect of the invention relates to a towing vehicle, and more particularly to a snow groomer with an arrangement or apparatus as described herein.
Dies ermöglicht den Einsatz auf bereits bestehenden und neuen Langlaufloipen.This allows use on existing and new cross-country ski trails.
Ein weiterer Aspekt der Erfindung betrifft ein Zugfahrzeug und vorzugsweise ein Pistenfahrzeug zum Ausführen des Verfahrens wie vorliegend beschrieben.Another aspect of the invention relates to a towing vehicle and, preferably, a snow groomer for carrying out the method as described herein.
Mit dem Pistenfahrzeug kann die Vorrichtung in Fahrtrichtung gezogen werden. Der Energieverbrauch zum Herstellen von Langlaufloipen und der Energiebedarf des Pistenfahrzeuges wird reduziert. Das Pistenfahrzeug kann sich schneller fortbewegen, was zu einer Zeitersparnis beim Spuren der Langlaufloipen führt.With the snow groomer, the device can be pulled in the direction of travel. The energy consumption for producing cross-country ski trails and the energy requirement of the snow groomer is reduced. The snow groomer can move faster, resulting in a time savings in the tracks of cross-country ski trails.
