Definitions
- the invention relates to a lifting and swiveling device for objects, in particular motor vehicles and the like, with substantially horizontally extending tie rods, with a frame which can be pivoted about a substantially horizontal axis of the tie rods and with a lifting device which rotates about a substantially horizontal axis of the Drawbars can be pivoted and is connected to the frame in an articulated manner via a holder which can be moved along it, the holder being designed to be displaceable along the lifting device and lockable at any point by means of an actuating device.
- Such a lifting device is known from EP-A 0 285 292. It is used there only to tip a vehicle to which a so-called “car cradle” is attached in order to avoid manual tipping. The lifting device is then removed and the car lies on the car cradle.
- Disadvantages of this device are the lack of a connection between the cradle and the lifting device when lifting and the risk of the car tipping over after the lifting device has been removed.
- the invention aims to provide a device of the type mentioned, which has the disadvantages of avoids previously known solutions while being easy to use and safe during every phase of use.
- the frame is a tensioning frame which has on its side facing away from the lifting device an essentially 90 ° curved and then again rectilinear support frame and in that fastening devices are provided on the tensioning frame for fixing the object to be tilted . That is why it is also mentioned in the description and the claims.
- the invention thus relates in particular to a four-point tilting device for motor vehicles, trailers, wagons, machines and components, consisting of the clamping frame, which can be pivoted to the dead center via an articulated lifting device to the bottom of the to be tilted
- the device preferably having a device through which the objects to be processed, if they are motor vehicles, can enter the tilting device and by means of a clamping device without dismantling the wheels on the clamping frame Tilting device can be fixed and by means of a winch or similar lifting device can be brought into the position required for processing by a person with little effort, a tilting device preventing overturning. The return to the starting position takes place by returning the lifting device.
- a safety device takes into account that the different dimensions of the objects to be tilted, in particular motor vehicles, corresponding to their different centers of gravity result in different tilt angles, which result in a variable tilt angle setting need to safely prevent overturning.
- the tilting device according to the invention is characterized in particular by the fact that an adjustable overturn protection reliably prevents the risk of overturning and can be adapted to all different tilting angles.
- the tensioning frame is preferably connected to the lifting device by means of tie rods in such a way that the tie rods on the tensioning frame are articulated in the middle of the set track width, so that the lifting device is always vertical at every tilt angle.
- the tilting device according to the invention is location-independent and can be set up and operated on a flat surface at the place of use required in each case.
- Similar tipping devices have the disadvantage that the objects to be tipped for the insertion into the tipping device are laborious and time-consuming to lift or that the wheels of a vehicle have to be dismantled and the vehicle has to be fastened to special holding devices before it can be brought into the corresponding working position .
- stationary machines can be pivoted into the clamping frame.
- the object to be tilted is fastened to a tensioning frame 4 by means of tensioning chains or straps 14.
- the clamping frame 4 is provided with a support frame, which can either be made in one piece or not with it.
- the clamping frame is articulated by means of brackets 23 on a lifting device 24.
- two extension arms 17 can be spread at the desired angle by means of adjusting spindles 18. They prevent the object from tipping over, the set angle depends on the geometry and the position of the center of gravity of the object.
- FIG. 2 shows a device according to the invention analogous to FIG. 1 without an object to be tilted and not yet fully assembled.
- One end of the pull rod 28 is not yet connected to the axis of the wheels 31 of the lifting device 24. This is shown more precisely than in FIG. 1:
- a slide 27 slides in a guide of the lifting device and is moved by means of a winch and a rope 29. The rope is deflected at the upper end 30 of the lifting device and runs from the carriage back to the end 30, so that a translation in the manner of a pulley block is achieved.
- the lifting device is provided at its lower end during assembly with a shoe 32, which is removed after the connection of the lifting device 24 with at least one pull rod 28, in order to be able to stand freely during assembly and has wheels 31 on whose axis the Tension rods 28 are attached in order to be able to follow the object to be tilted in the course of their actuation, as can be seen from FIG. 1.
- the wheels 31 enable the entire, fully assembled device to be moved like a sliding chest by a single person, who only has to grip and lift the extension arms 17.
- the usual track widths of vehicles is adjustable, the setting of the track widths being fixed by means of two bolts 6 at a close distance, for example 4 cm in FIG. 2 or at a distance of 8 cm of the holes 7 in FIG. 3 with secured bolts.
- the track gauges are therefore to be fixed at a distance from the boreholes 6, in the example at intervals of 4 cm.
- a stiffened support frame 15 (FIG. 5) is fastened, for example with secured bolts 16, which can also be attached in the same way to the lifting side of the tensioning frame 5, so that the tilting device can be used equally from both sides .
- two cantilever arms 17 are attached in an articulated connection as an anti-tip device 17, 18, which can be adjusted to the tilt angle dependent on the center of gravity of the workpiece or vehicle is. With two extension arms, unevenness in the floor at the installation site of the tipping device can be compensated.
- the load on the lifting device that is still present can be read off in every tilting angle position during the lifting process, so that the support height on the tilting side, for example with the crank the spindle 18, can be set in good time and thus the risk of overturning can be eliminated with certainty.
- the lifting device 24 rests on the floor with rollers or wheels and is with articulated pull rods 28 with the clamping frame part 4 or depending on the working side with the clamping frame part 5, connected with secured bolts.
- the length of the tie rods 28 can be adjusted to the track width of the vehicles or other workpieces to be machined.
- the tie rods 28 are provided with the same number of holes at the same distance as on the tenter frame 4, 5 for adjustment to the track width and are fastened with secured bolts, which are preferably located in the middle of the set track width on the tenter frame 4, 5, so that the lifting device 24 during the lifting process, from the smallest to the largest angle of inclination of the tilted clamping frame, is substantially vertical so that the workpiece or vehicle in the clamping frame cannot be touched by the lifting column or lifting device 24.
- a preferred embodiment of the invention is characterized in that both ends of the tensioning frame 4, 5 are designed to fasten the support frame 15 and the lifting device 24 and that when the object to be tilted is fastened, both the support frame and the lifting device can be fastened to the tensioning frame. This allows you to tilt the object first in one direction, then in the other, without having to undo the attachment.
- a further embodiment of the invention provides that the lifting device 24 is releasably connected to the stenter and that, for safety reasons, a support (not shown) is connected to the stenter in its place after the object has been tilted. This support is either replaced by the lifting device for tipping back or enables the device to be tipped back by a brake. This means that several clamping frames can be operated alternately with just one lifting device.

Abstract
Description
Die Erfindung betrifft eine Hebe- und Schwenkvorrichtung für Gegenstände, insbesonders Kraftfahrzeuge u.dgl., mit im wesentlichen waagrecht verlaufenden Zugstangen, mit einem um eine im wesentlichen horizontale Achse der Zugstangen verschwenkbaren Rahmen und mit einer Hebeeinrichtung, die um eine im wesentlichen horizontale Achse der Zugstangen schwenkbar ist und über eine an ihr entlang bewegbare Halterung mit dem Rahmen gelenkig verbunden ist, wobei die Halterung mittels einer Betätigungsvorrichtung entlang der Hebeeinrichtung verschieblich und an beliebiger Stelle arretierbar ausgebildet ist.The invention relates to a lifting and swiveling device for objects, in particular motor vehicles and the like, with substantially horizontally extending tie rods, with a frame which can be pivoted about a substantially horizontal axis of the tie rods and with a lifting device which rotates about a substantially horizontal axis of the Drawbars can be pivoted and is connected to the frame in an articulated manner via a holder which can be moved along it, the holder being designed to be displaceable along the lifting device and lockable at any point by means of an actuating device.
Eine derartige Hebevorrichtung ist aus der EP-A 0 285 292 bekannt. Sie dient dort ausschließlich dazu, ein Fahrzeug, an dem eine sogenannte "Autowiege" befestigt ist, zu kippen, um das händische Kippen zu vermeiden. Anschließend daran wird die Hebevorrichtung entfernt, und das Auto liegt auf der Autowiege.Such a lifting device is known from EP-A 0 285 292. It is used there only to tip a vehicle to which a so-called "car cradle" is attached in order to avoid manual tipping. The lifting device is then removed and the car lies on the car cradle.
Nachteilig bei dieser Vorrichtung ist das Fehlen einer Verbindung zwischen der Wiege und der Hebevorrichtung beim Heben und die Gefahr des Zurückkippens des Autos, nachdem die Hebevorrichtung entfernt worden ist.Disadvantages of this device are the lack of a connection between the cradle and the lifting device when lifting and the risk of the car tipping over after the lifting device has been removed.
Eine andere Kippvorrichtung gemäß der EP-A 0 410 013 vermeidet diese Nachteile, doch muß zu ihrer Benutzung das Fahrzeug aufgebockt werden, um alle Räder entfernen zu können und an den Radaufnahmen entsprechende Teile der Vorrichtung montieren zu können. Der Aufwand ist bei einer Totalrenovierung der Bodenplatte gering, für eine Inspektion aber viel zu aufwendig.Another tilting device according to EP-A 0 410 013 avoids these disadvantages, but in order to use it the vehicle must be jacked up in order to be able to remove all wheels and to be able to mount corresponding parts of the device on the wheel receptacles. The effort for a total renovation of the floor slab is low, but much too expensive for an inspection.
Die Erfindung zielt darauf ab, eine Vorrichtung der eingangs genannten Art zu schaffen, die die Nachteile der vorbekannten Lösungen vermeidet und dabei bequem zu bedienen und während jeder Phase der Benutzung sicher ist.The invention aims to provide a device of the type mentioned, which has the disadvantages of avoids previously known solutions while being easy to use and safe during every phase of use.
Erfindungsgemäß erreicht man diese Ziele dadurch, daß der Rahmen ein Spannrahmen ist, der an seiner der Hebeeinrichtung abgewandten Seite einen im wesentlichen um 90° gebogenen und anschließend wieder geradlinig verlaufenden Stützrahmen aufweist und dadurch, daß am Spannrahmen Befestigungsvorrichtungen zur Fixierung des zu kippenden Gegenstandes vorgesehen sind. Deshalb wird er auch in der Beschreibung und den Ansprüchen Spannrahmen genannt.According to the invention, these objectives are achieved in that the frame is a tensioning frame which has on its side facing away from the lifting device an essentially 90 ° curved and then again rectilinear support frame and in that fastening devices are provided on the tensioning frame for fixing the object to be tilted . That is why it is also mentioned in the description and the claims.
Die Erfindung bezieht sich somit insbesonders auf eine auf vier Punkten aufliegende Kippvorrichtung für Kraftfahrzeuge, Anhänger, Waggons, Maschinen und Bauteile, bestehend aus dem Spannrahmen, welcher über eine gelenkig mit ihm verbundene Hebeeinrichtung in den Totpunkt geschwenkt werden kann, um die Unterseite des zu kippenden Gegenstandes für Wartung, Reparatur und Montagearbeiten in einfacher Weise zugänglich zu machen, wobei die Vorrichtung bevorzugt eine Einrichtung aufweist, durch die die zu bearbeitenden Gegenstände, wenn sie Kraftfahrzeuge sind, in die Kippvorrichtung einfahren können und mittels einer Spannvorrichtung ohne Demontage der Räder am Spannrahmen der Kippvorrichtung fixiert werden können und mittels einer Winde oder ähnlichen Hebeeinrichtung von einer Person mit geringem Kraftaufwand in für die Bearbeitung erforderliche Position gebracht werden kann, wobei eine Überkippsicherung das Überkippen verhindert. Die Rückführung in die Ausgangsposition erfolgt durch Rücklauf der Hebeeinrichtung.The invention thus relates in particular to a four-point tilting device for motor vehicles, trailers, wagons, machines and components, consisting of the clamping frame, which can be pivoted to the dead center via an articulated lifting device to the bottom of the to be tilted To make the object accessible for maintenance, repair and assembly work in a simple manner, the device preferably having a device through which the objects to be processed, if they are motor vehicles, can enter the tilting device and by means of a clamping device without dismantling the wheels on the clamping frame Tilting device can be fixed and by means of a winch or similar lifting device can be brought into the position required for processing by a person with little effort, a tilting device preventing overturning. The return to the starting position takes place by returning the lifting device.
Eine erfindungsgemäße Sicherheitseinrichtung berücksichtigt, daß die unterschiedlichen Dimensionen der zu kippenden Gegenstände, insbesonders Kraftfahrzeuge, entsprechend ihrer unterschiedlichen Schwerpunktlagen unterschiedliche Kippwinkel zur Folge haben, die eine variable Kippwinkeleinstellung benötigen, um ein Überkippen sicher zu verhindern.A safety device according to the invention takes into account that the different dimensions of the objects to be tilted, in particular motor vehicles, corresponding to their different centers of gravity result in different tilt angles, which result in a variable tilt angle setting need to safely prevent overturning.
Die erfindungsgemäße Kippvorrichtung zeichnet sich insbesonders dadurch aus, daß eine regulierbare Überkippsicherung die Gefahr des Überkippens sicher verhindert und auf alle unterschiedlichen Kippwinkel adaptiert werden kann.The tilting device according to the invention is characterized in particular by the fact that an adjustable overturn protection reliably prevents the risk of overturning and can be adapted to all different tilting angles.
Erfindungsgemäß ist einerseits für eine sichere Verbindung zwischen der eigentlichen Hebevorrichtung und dem Stützrahmen, der als Wiege dient, gesorgt und ein Zurückrollen zuverläßig vermieden, anderseits ist jede Vorbereitung des Gegenstandes, insbesonders des Fahrzeuges überflüssig geworden.According to the invention, on the one hand, a secure connection between the actual lifting device and the support frame, which serves as a cradle, is ensured and rolling back is reliably avoided, on the other hand, any preparation of the object, in particular of the vehicle, has become superfluous.
Bevorzugt ist der Spannrahmen mit der Hebeeinrichtung mittels Zugstangen derart verbunden, daß die Zugstangen am Spannrahmen in der Mitte der eingestellten Spurweite gelenkig verbunden sind, sodaß die Hebeeinrichtung bei jeder Kippwinkelweite immer senkrecht steht.The tensioning frame is preferably connected to the lifting device by means of tie rods in such a way that the tie rods on the tensioning frame are articulated in the middle of the set track width, so that the lifting device is always vertical at every tilt angle.
Bisher wurden für Arbeiten am Fahrzeugboden Montagegruben und Hebebühnen verwendet, die architektonische Baumaßnahmen für die Installierung erforderlich machten. Die erfindungsgemäße Kippvorrichtung ist ortsungebunden und kann am jeweils benötigten Einsatzort auf einer ebenen Fläche aufgestellt und betrieben werden.So far, assembly pits and lifting platforms have been used for work on the vehicle floor, which made architectural construction measures necessary for the installation. The tilting device according to the invention is location-independent and can be set up and operated on a flat surface at the place of use required in each case.
Ähnliche Kippvorrichtungen haben den Nachteil, daß die zu kippenden Gegenstände für die Einbringung in die Kippvorrichtung arbeits- und zeitaufwendig angehoben bzw., daß bei einem Fahrzeug die Räder demontiert und das Fahrzeug an besonderen Haltevorrichtungen befestigt werden muß, bevor es in entsprechende Arbeitsposition gebracht werden kann. Entsprechend der erfindungsgemäßen Anwendung der Kippvorrichtung können stationäre Maschinen in den Spannrahmen eingeschwenkt werden.Similar tipping devices have the disadvantage that the objects to be tipped for the insertion into the tipping device are laborious and time-consuming to lift or that the wheels of a vehicle have to be dismantled and the vehicle has to be fastened to special holding devices before it can be brought into the corresponding working position . According to the application of the tilting device according to the invention, stationary machines can be pivoted into the clamping frame.

Wie aus Fig. 1 ersichtlich, ist der zu kippende Gegenstand mittels Spannketten bzw. -riemen 14 an einem Spannrahmen 4 befestigt. Einerseits ist der Spannrahmen 4 mit einem Stützrahmen versehen, der entweder einstückig oder auch nicht mit ihm ausgebildet sein kann. Am anderen Ende ist der Spannrahmen mittels Laschen 23 an einer Hebevorrichtung 24 gelenkig montiert.As can be seen from FIG. 1, the object to be tilted is fastened to a tensioning
Zwischen dem Spannrahmen 4 und dem unteren Teil der Hebevorrichtung 24 verlauft wenigstens eine Zugstange 28, durch die der Spannrahmen, die Hebevorrichtung und die Zugstangen stets ein Dreieck bilden und so statisch bestimmt sind.Between the
Am Stützrahmen 15 sind zwei Auslegerarme 17 mittels Einstellspindeln 18 in gewünschtem Winkel abspreizbar. Sie verhindern das Überkippen des Gegenstandes, der eingestellte Winkel hängt von der Geometrie und der Lage des Schwerpunktes des Gegenstandes ab.On the
Die Fig. 2 zeigt eine erfindungsgemäße Vorrichtung analog zu Fig. 1 ohne einen zu kippenden Gegenstand und noch nicht völlig fertig montiert. Dabei ist ein Ende der Zugstange 28 noch nicht mit der Achse der Räder 31 der Hebevorrichtung 24 verbunden. Diese ist genauer als in Fig. 1 gezeigt: Ein Schlitten 27 gleitet in einer Führung der Hebevorrichtung und wird mittels einer Winde und eines Seils 29 bewegt. Das Seil wird am oberen Ende 30 der Hebevorrichtung umgelenkt und läuft vom Schlitten auch wieder zum Ende 30 zurück, sodaß eine Übersetzung nach Art eines Flaschenzuges erreicht wird.FIG. 2 shows a device according to the invention analogous to FIG. 1 without an object to be tilted and not yet fully assembled. One end of the
Die Hebevorrichtung ist an ihrem unteren Ende während der Montage mit einem Schuh 32, der nach der Verbindung der Hebevorrichtung 24 mit zumindest einer Zugstange 28 entfernt wird, versehen, um während der Montage frei stehen zu können und weist Räder 31 auf, auf deren Achse die Zugstangen 28 befestigt werden, um im Zuge ihrer Betätigung dem zu kippenden Gegenstand folgen zu können, wie dies aus Fig. 1 ersichtlich ist. Darüberhinaus ermöglichen es die Räder 31, daß die gesamte fertig montierte Vorrichtung ähnlich einer Schiebetruhe von einer einzelnen Person verfahren werden kann, die dazu nur die Auslegerarme 17 ergreifen und anheben muß.The lifting device is provided at its lower end during assembly with a
Die Benutzung der Vorrichtung wird im folgenden anhand des Kippens eines Fahrzeuges beschrieben, ohne darauf beschränkt zu sein.The use of the device is described below with reference to the tilting of a vehicle, without being restricted to this.
Von rechts oder links rollen Fahrzeuge auf den eigenen Rädern über eine Ein- und Ausfahrtsrampe 1, die mit Bolzen 2 in Buchsen 3 eingehängt sind, in einen aus zwei Teilen bestehenden Spannrahmen 4, 5, der auf die Breite der zu bearbeitenden Werkstücke, vorzugsweise auf die gängigen Spurweiten von Fahrzeugen, einstellbar ist, wobei die Einstellung der Spurweiten über zwei Bohrungen 6 in engem Abstand, beispielsweise 4 cm in Fig. 2 oder im Abstand von 8 cm der Bohrungen 7 in Fig. 3 mit gesicherten Bolzen fixiert wird. Die Spurweiten sind also im Abstand der Bohrlöcher 6, im Beispielsfall in Abständen von 4 cm, zu fixieren.From the right or left vehicles roll on their own wheels via an entry and exit ramp 1, which are suspended with bolts 2 in
Je eine auf den beiden Spannrahmenteilen 4, 5 gleitende, mit Klemmschellen 9 verbundenen Klemmschiene 8, die an die Innenseite der Räder angelegt werden, fixieren durch die beim Niederspannen der Räder entstehende Zugkraft der Spannketten 13, 14 mittels des Schließringes 10 die Klemmschienen an den Spannrahmen 4, 5. An den Stirnseiten der Spannrahmen 4, 5 sind Laschen 11 angebracht, in die ein Ring 12 eingehängt ist, durch den die Spannketten 13, 14 am Spannring 10, beispielsweise über die Räder der Fahrzeuge oder Halterungen der Werkstücke geführt und mittels einer Spannvorrichtung 14 gespannt werden.One on each of the two tensioning
An der Kippseite des Spannrahmens 4 ist ein versteifter Stützrahmen 15 (Fig. 5), beispielsweise mit gesicherten Bolzen 16 befestigt, der in der gleichen Weise auch an der Hebeseite des Spannrahmens 5 befestigt werden kann, sodaß die Kippvorrichtung von beiden Seiten gleichermaßen genutzt werden kann.On the tilting side of the
Am oberen Teil des Stützrahmens 14 sind als Überkippsicherung 17, 18, 19 zwei Auslegerarme 17 in gelenkiger Verbindung angebracht, die auf den vom Schwerpunkt des Werkstückes oder Fahrzeuges abhängigen Kippwinkel einstellbar ist. Mit zwei Auslegerarmen können Bodenunebenheiten am Aufstellort der Kippvorrichtung ausgeglichen werden.On the upper part of the
Diese Überkippsicherung besteht erfindungsgemäß aus einer - für die erforderliche Stützhöhe einstellbaren - Vorrichtung, beispielsweise mit zwei Spindeln mit Kurbel 18, an der beispielsweise ein Stoßdämpfer angebracht ist, an dem eine Markierung, beispielsweise eine Farbmarkierung 19 den Gleichgewichtszustand anzeigt:
- "grün" Kippseite ist unbelastet, Heberseite ist belastet,
- "gelb" Kippseite und Heberseite sind unbelastet, das Werkstück bzw. die Fahrzeugseite befindet sich in idealer Totpunktlage,
- "rot" die Kippseite ist überlastet und die Heberseite ist unbelastet. In diesem Fall verhindert die Überkippsicherung die Gefahr eines Überkippens des Werkstückes oder Fahrzeuges.
- "green" tipping side is not loaded, lifting side is loaded,
- "yellow" tilt side and jack side are not loaded, the workpiece or the vehicle side is in an ideal dead center position,
- "red" the tipping side is overloaded and the lifting side is unloaded. In this case, the tilt protection prevents the risk of the workpiece or vehicle tipping over.
In Verbindung mit einer Lastanzeigevorrichtung 26, beispielsweise einer Federwaage an der Hebeeinrichtung 24, kann während des Hebevorganges in jeder Kippwinkelstellung die noch vorhandene Belastung der Hebeeinrichtung abgelesen werden, sodaß die Abstützhöhe an der Kippseite, beispielsweise mit der Kurbel die Spindel 18, rechtzeitig vorsorglich eingestellt werden und damit mit Sicherheit die Gefahr des Überkippens ausgeschaltet werden kann.In connection with a
An der Kupplung 20, die je nach Platz- und Arbeitserfordernis am Spannrahmen an der Heberseite 4, 5, beispielsweise mit Einschüben 21 und gesichertem Bolzen 22 zu befestigen ist, ist eine Lasche 23 oder eine andere Verbindungsvorrichtung für die Aufnahme eines Lastarmes der Hebeeinrichtung 24 als gelenkige, bei Montage und Demontage lösbare Verbindung angebracht.On the
Die Hebeeinrichtung 24 liegt mit Rollen oder Rädern am Boden auf und ist mit gelenkig angebrachten Zugstangen 28 mit dem Spannrahmenteil 4 oder je nach Arbeitsseite mit dem Spannrahmenteil 5, mit gesicherten Bolzen verbunden. Die Zugstangen 28 sind in ihrer Länge auf die Spurbreite der zu bearbeitenden Fahrzeuge oder anderer Werkstücke einstellbar.The lifting
Die Zugstangen 28 sind zur Einstellung auf die Spurweite mit der gleichen Anzahl Bohrungen im gleichen Abstand wie am Spannrahmen 4, 5, versehen und werden mit gesicherten Bolzen, die sich bevorzugt in der Mitte der eingestellten Spurweite am Spannrahmen 4, 5, befinden, befestigt, sodaß die Hebeeinrichtung 24 während des Hebevorganges, vom kleinsten bis zum größten Neigungswinkel des gekippten Spannrahmens im wesentlichen soweit senkrecht steht, daß das Werkstück oder Fahrzeug im Spannrahmen von der Hebersäule oder Hebeeinrichtung 24 nicht berührt werden kann.The
Eine bevorzugte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß beide Enden des Spannrahmens 4, 5 zur Befestigung des Stützrahmens 15 und der Hebevorrichtung 24 ausgebildet sind und daß bei befestigtem zu kippendem Gegenstand eine Befestigung sowohl des Stützrahmens als auch der Hebevorrichtung am Spannrahmen möglich ist. Dadurch kann man, ohne die Befestigung lösen zu müssen, den Gegenstand zuerst in die eine, dann in die andere Richtung kippen.A preferred embodiment of the invention is characterized in that both ends of the
Eine weitere Ausgestaltung der Erfindung sieht vor, daß die Hebevorrichtung 24 lösbar mit dem Spannrahmen verbunden ist und daß aus Sicherheitsgründen eine - nicht dargestellte - Abstützung nach dem Kippen des Gegenstandes an ihrer Stelle mit dem Spannrahmen verbunden wird. Diese Abstützung wird entweder Zum zurückkippen wieder durch die Hebevorrichtung ersetzt oder ermöglicht durch eine Bremse ein Zurückkippen der Vorrichtung. Damit können mehrere Spannrahmen mit nur einer Hebevorrichtung abwechselnd bedient werden.A further embodiment of the invention provides that the
