Description

eckiges, steifes Gebilde, das als Ganzes vom Fahrgestell bzw. vom Fahrzeug lösbar ist. In der Nähe der Abkröpfungsstelle ist der Rahmen 6 als Gerätetragrahmen auf jeder Seite mit einem Lager 13 versehen, das zur schwenkbaren Abstützung von Armen 14 dient. Diese Schwenkarme 14 sind am vorderen freien Ende mit einer Ladeschaufel 15 gelenkig verbunden. Die Arme 14 und mit diesen die Ladeschaufel 15 lassen sich mit Hilfe von hydraulischen Hubaggregaten 16 hochschwenken, so daß sie dann die in F i g. 1 in unterbrochenen Linien dargestellte Lage einnehmen. Jeder der beiden Zylinder 17 des Hubaggregates 16 ist an einer am Rahmen 6 starr befestigten Eckstütze angelenkt, während die Kolbenstange 18 mit ihrem freien Ende an einer die Armteile verbindenden Lasche 20 angreift. Durch Zufuhr von Druckflüssigkeit in das Innere des Zylinders 17 wird der Kolben aus diesem herausgestoßen und bewirkt dadurch, daß sich die Arme 14 und damit die Schaufel 15 in Richtung des Pfeiles^ in die sogenannte Überkopflage verschwenken. Ein weiteres hydraulisches Hubaggregat-Paar 21 dient zur Verschwenkung der Schaufel 15 um eine horizontale Drehachse. Die Zylinder 23 dieser Hubaggregate 21 sind je an Armen 14 gelenkig festgemacht, während die Kolbenstange 24 an einem von der Schwenkachse entfernt liegenden Stützblech 25 an der Schaufel gelenkig abgestützt ist. Dadurch kann die Schaufel 15 zwischen der in vollen und der in unterbrochenen Linien dargestellten Lage bewegt werden.angular, rigid structure, the whole of the chassis or is detachable from the vehicle. In the vicinity of the abutment point, the frame 6 is used as a device support frame Provided on each side with a bearing 13, which is used for the pivotable support of arms 14 serves. These pivot arms 14 are articulated to a loading shovel 15 at the front free end. The arms 14 and with these the loading shovel 15 can be lifted with the aid of hydraulic lifting units 16 swivel up, so that they then in F i g. 1 position shown in broken lines take in. Each of the two cylinders 17 of the lifting unit 16 is rigidly attached to one on the frame 6 Corner support hinged, while the piston rod 18 with its free end on one of the arm parts connecting tab 20 engages. By supplying pressure fluid into the interior of the cylinder 17 the piston is pushed out of this and thereby causes the arms 14 and thus the Swivel blade 15 in the direction of arrow ^ into the so-called overhead position. Another one Hydraulic lifting unit pair 21 is used to pivot the shovel 15 about a horizontal one Axis of rotation. The cylinders 23 of these lifting units 21 are each articulated to arms 14 while the piston rod 24 on a support plate 25 on the blade, which is remote from the pivot axis is articulated. This allows the blade 15 between the full and the broken Lines shown position are moved.

Ein Teleskop-Hubaggregat 27 ist am Fahrgestell schwenkbar abgestützt und drückt bei Zufuhr von Druckflüssigkeit die Lademulde 5 in die in unterbrochenen Linien dargestellte Kipplage. Beim dargestellten Ausführungsbeispiel liegt das obere Ende des Teleskop-Hubaggregates lose gegen ein Widerlager in der Mulde 5 an. Dieses Teleskop-Hubaggregat 27 ist mit dem Gerätetragrahmen 6 schwenkbar verbunden, so daß es samt diesem abgehoben werden kann.A telescopic lifting unit 27 is pivotably supported on the chassis and pushes when it is supplied Hydraulic fluid the loading tray 5 in the tilted position shown in broken lines. When shown Embodiment, the upper end of the telescopic lifting unit is loosely against an abutment in the trough 5. This telescopic lifting unit 27 is pivotably connected to the device support frame 6, so that it can be lifted off together with this.

Sowohl die Ladeschaufel 15 als auch die Mulde sind mit einer die Haftung an Schnee verringernden Kunststoff-Schicht oder -Lack, beispielsweise auf Polyamid-Basis, versehen.Both the loading shovel 15 and the trough are provided with a one which reduces the adhesion to snow Plastic layer or lacquer, for example based on polyamide, provided.

Die Steuerung der verschiedenen Bewegungen derControlling the various movements of the

ίο Hubaggregate erfolgt durch nicht näher dargestellte Handsteuerhebel im Inneren der Fahrerkabine. Jedes der Hubaggregate bzw. Hubaggregat-Paare 16, 21, 27 läßt sich individuell bewegen. Die Druckanlage, vorzugsweise eine Ölpumpe, für die Speisung der Hubaggregate ist fahrzeugfest eingebaut. Zwischen den fahrzeugfesten Rohr- oder Schlauch-Leitungsteilen und den rahmenfesten Leitungsteilen befindet sich ein lösbares Kupplungsstück 28, so daß die Leitungen getrennt werden können, wenn der Gerätetragrahmen vom Fahrgestell abgehoben werden soll.ίο Lifting units are carried out by not shown in detail Hand control lever inside the driver's cab. Each of the lifting units or lifting unit pairs 16, 21, 27 can be moved individually. The pressure system, preferably an oil pump, for feeding the lifting units is installed permanently in the vehicle. Between the pipe or hose line parts that are fixed to the vehicle and the frame-fixed line parts is a releasable coupling piece 28, so that the lines can be separated when the equipment support frame is to be lifted off the chassis.

Dadurch ist es möglich, den Rahmen 6 samt der an ihm befestigten Ladeschaufel 15, den Armen 14, den Hubaggregaten 16, 21 und 27 und der Mulde 5 als eine zusammenhängende Einheit auf das Chassis von oben her — beispielsweise mittels eines Kranes — aufzusetzen und abzuheben.This makes it possible to move the frame 6 together with the loading shovel 15 attached to it, the arms 14, the lifting units 16, 21 and 27 and the trough 5 as a coherent unit on the chassis from above - for example by means of a crane - to set up and lift off.

An Stelle von Raupen könnte das Fahrzeug auch mit Rädern versehen sein.Instead of caterpillars, the vehicle could also be provided with wheels.

Mehrzweck-Fahrzeuge der beschriebenen Art eignen sich besonders für den Unterhalt von Skipisten. Sie können daneben aber auch als Transportfahrzeuge im Schnee, als Schneepflug und für Schneeräumungsarbeiten eingesetzt werden, da der Aufwand für die jeweilige Umstellung vergleichsweise gering ist.Multipurpose vehicles of the type described are particularly suitable for maintaining ski slopes. They can also be used as transport vehicles in the snow, as a snow plow and for snow removal work, as the effort is comparatively low for the respective changeover.
