Description
Die vorliegende Erfindung betrifft eine Gabelklemme zum Festlegen an einem Zinken einer Gabel einer Hubeinrichtung, insbesondere eines Gabelstaplers, mit den Merkmalen des Oberbegriffs des Anspruchs 1. Die Erfindung betrifft außerdem eine Hubeinrichtung, insbesondere ein Gabelstapler, die bzw. der mit wenigstens einer derartigen Gabelklemme ausgestattet ist. Die Erfindung betrifft ferner ein Verzurrungsset zum Verzurren eines Ladeguts an einer Gabel einer Hubeinrichtung, das mit wenigstens einer derartigen Gabelklemme ausgestattet ist. Schließlich umfasst die vorliegende Erfindung noch eine Verwendung einer derartigen Gabelklemme bzw. eines derartigen Verzurrungssets.The present invention relates to a fork clamp for fixing to a tine of a fork of a lifting device, in particular a forklift, with the features of the preamble of
Hubeinrichtungen, die insbesondere an einem Gabelstapler angeordnet sein können, umfassen eine Gabel, die horizontal abstehende Zinken aufweist und vertikal verstellbar ist. Insbesondere in Verbindung mit einem Gabelstapler werden mit Hilfe derartiger Hubeinrichtungen Lasten bzw. Ladegüter angehoben und transportiert, um sie von einem ersten Ort an einen zweiten Ort zu überführen. Üblicherweise steht die Last oder Ladung dabei auf einer Palette, die für einen Eingriff der Zinken der Gabel genormt ist. Derartige Hubeinrichtungen werden jedoch auch häufig dazu verwendet, Lasten unmittelbar, also ohne die Verwendung einer Palette, anzuheben und ggf. in Verbindung mit einem Gabelstapler zu transportieren. Beim Transport von unmittelbar auf der Gabel aufliegenden Lasten besteht das Problem, dass das Ladegut beim Beschleunigen, beim Abbremsen sowie bei Kurvenfahrten des Gabelstaplers ebenso wie beim Überfahren von Unebenheiten relativ zur Gabel verrutschen kann und im Extremfall sogar davon herabfallen kann. Gerade bei schweren Lasten besteht dabei eine erhöhte Unfallgefahr. Besonders kritisch sind dabei metallische Lasten, wie Maschinen, Metallboxen und dergleichen, da diese auf den ebenfalls metallischen Zinken der Gabel nur einen geringen Reibungswiderstand besitzen, so dass schon relativ geringe Kräfte ausreichen, die Last gegenüber der Gabel zu verrutschen. Im vorliegenden Zusammenhang werden die Begriffe "Last", "Ladung" und "Ladegut" synonym verwendet.Lifting devices, which may be arranged in particular on a forklift, comprise a fork which has horizontally protruding tines and is vertically adjustable. In particular, in connection with a forklift with the help of such lifting devices loads or goods are lifted and transported in order to transfer them from a first location to a second location. Usually, the load or load is on a pallet that is standardized for engagement of the tines of the fork. However, such lifting devices are also often used to lift loads directly, so without the use of a pallet, and possibly to transport in conjunction with a forklift. When transporting loads directly on the fork there is the problem that the load can slip relative to the fork during acceleration, braking and cornering of the forklift as well as when driving over bumps and in extreme cases even fall from it. Especially with heavy loads there is an increased risk of accidents. Particularly critical are metallic loads, such as machines, metal boxes and the like, as these on the also metallic teeth of the Fork have only a low frictional resistance, so that even relatively small forces are sufficient to slip the load against the fork. As used herein, the terms "load", "load" and "load" are used interchangeably.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für das Transportieren von Ladegut auf einer Gabel einer Hubeinrichtung einen vorteilhaften Weg aufzuzeigen, der sich dadurch auszeichnet, dass die Gefahr reduziert ist, dass das Ladegut von der Gabel herabfällt.The present invention is concerned with the problem of pointing out an advantageous way for the transport of cargo on a fork of a lifting device, which is characterized in that the risk is reduced that the load falls from the fork.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matter of the independent claim. Advantageous embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, eine Gabelklemme vorzuschlagen, die an einem Zinken einer Gabel einer Hubeinrichtung, insbesondere eines Gabelstaplers, befestigt werden kann. Mit Hilfe einer derartigen Gabelklemme kann zum einen ein Verrutschen einer Ladung entlang des jeweiligen Zinkens bzw. entlang der Gabel schon dadurch reduziert werden, dass die Gabelklemme als Anschlag für die jeweilige Last in der Längsrichtung des jeweiligen Zinkens dient. Darüber hinaus lässt sich eine derartige Gabelklemme auch zum Verzurren der jeweiligen Last an der Gabel nutzen, beispielsweise in Verbindung mit einem entsprechenden Gurt oder Seil oder in Verbindung mit einer entsprechenden Kette.The invention is based on the general idea to propose a fork clamp, which can be attached to a prong of a fork of a lifting device, in particular a forklift. With the help of such a fork clamp on the one hand slipping a load along the respective Zinc or along the fork already be reduced by the fact that the fork clamp serves as a stop for the respective load in the longitudinal direction of the respective tine. In addition, such a fork clamp can also be used for lashing the respective load on the fork, for example in conjunction with a corresponding belt or rope or in conjunction with a corresponding chain.
Eine derartige Gabelklemme besitzt eine Basisplatte, von der zwei in einer Abstandsrichtung voneinander beabstandete Seitenstege abstehen. Zweckmäßig können die beiden Seitenstege dabei endseitig, also an den voneinander abgewandten Enden der Basisplatte, angeordnet sein. Des weiteren ist die Gabelklemme mit einer Abdeckplatte ausgestattet, die gegenüber der Basisplatte mit Spannschrauben an den Seitenstegen befestigt werden kann. Die Basisplatte, die Abdeckplatte und die beiden Seitenstege umschließen einen Hohlraum bzw. eine Durchgangsöffnung, durch die ein Zinken einer Gabel einführbar ist. Dementsprechend umschließt die Gabelklemme im montierten Zustand den jeweiligen Zinken in der Umfangsrichtung des Zinkens.Such a fork clamp has a base plate, projecting from the two spaced apart in a distance direction side webs. Suitably, the two side webs can be arranged at the end, ie at the ends of the base plate facing away from one another. Furthermore, the fork clamp equipped with a cover plate, which can be attached to the base plate with clamping screws on the side bars. The base plate, the cover plate and the two side bars enclose a cavity or a through opening through which a prong of a fork can be inserted. Accordingly, the fork clamp in the assembled state surrounds the respective prongs in the circumferential direction of the tine.
Um nun die Gabelklemme an unterschiedlich breite Zinken anpassen zu können, ist bei der hier vorgestellten, erfindungsgemäßen Gabelklemme außerdem gemäß einer ersten Lösung vorgesehen, dass zwischen den beiden Seitenstegen wenigstens zwei verschiedene Abstände einstellbar sind. Hierzu ist wenigstens einer der beiden Seitenstege relativ zur Basisplatte und relativ zur Abdeckplatte verstellbar angeordnet. Ebenso ist grundsätzlich möglich, den einen Seitensteg nur gegenüber der Basisplatte verstellbar anzuordnen und gleichzeitig den anderen Seitensteg nur gegenüber der Abdeckplatte verstellbar anzuordnen. Zum Verändern des Abstands zwischen den beiden Seitenstegen werden dann auch die Basisplatte und die Abdeckplatte in der Abstandsrichtung relativ zueinander bewegt.In order to be able to adapt the fork clamp to different width tines, is also provided according to the invention, according to the invention, according to a first solution that at least two different distances between the two side bars are adjustable. For this purpose, at least one of the two side bars is arranged relative to the base plate and relative to the cover plate adjustable. Likewise, it is in principle possible to arrange the one side web adjustable only with respect to the base plate and at the same time to arrange the other side web only relative to the cover plate adjustable. To change the distance between the two side bars then the base plate and the cover plate are moved in the direction of spacing relative to each other.
Gemäß einer zweiten Lösung ist zwischen den beiden Seitenstegen zumindest ein Zwischensteg einsetzbar. Durch das Einsetzen eines derartigen Zwischenstegs wird der für den jeweiligen Zinken zwischen den beiden Seitenstegen nutzbare Abstand auf den Abstand des Zwischenstegs zu einem der Seitenstege reduziert. Bevorzugt wird dabei der Abstand bezüglich des zum Zwischensteg distal angeordneten Seitenstegs genutzt.According to a second solution, at least one intermediate web can be used between the two side webs. By inserting such a gutter usable for the respective prongs between the two side bars distance is reduced to the distance of the gutter to one of the side bars. Preferably, the distance is used with respect to the gutter distally arranged side bar.
Grundsätzlich ist jedoch auch eine Ausführungsform denkbar, die sowohl ein Verstellen wenigstens eines der Seitenstege als auch das Einsetzen eines Zwischenstegs ermöglicht.In principle, however, an embodiment is conceivable which allows both an adjustment of at least one of the side webs and the insertion of a gutter.
Entsprechend einer vorteilhaften Ausführungsform kann zumindest einer der Seitenstege mittels wenigstens einer Befestigungsschraube an der Basisplatte befestigt oder befestigbar sein, wobei die Basisplatte für die jeweilige Befestigungsschraube wenigstens zwei in der Abstandsrichtung beabstandete separate Durchgangsöffnungen oder ein sich in der Abstandsrichtung erstreckendes Langloch aufweist, wobei die jeweilige Befestigungsschraube zum Befestigen des jeweiligen Stegs durch die jeweilige Durchgangsöffnung bzw. durch das jeweilige Langloch einführbar ist. Die Abdeckplatte besitzt dann zweckmäßig für die jeweilige Spannschraube wenigstens zwei in der Abstandsrichtung beabstandete separate Durchgangsöffnungen oder ein sich in der Abstandsrichtung erstreckendes Langloch, so dass die jeweilige Spannschraube zum Verbinden der Abdeckplatte mit dem jeweiligen Seitensteg durch die jeweilige Durchgangsöffnung bzw. durch das Langloch einführbar ist. Hierdurch wird eine mechanisch einfach aufgebaute und somit einfach bedienbare Ausführungsform geschaffen, die eine hohe Funktionssicherheit bietet.According to an advantageous embodiment, at least one of the side webs can be fastened or attachable to the base plate by means of at least one fastening screw, wherein the base plate for the respective fastening screw has at least two separate passage openings spaced apart in the spacing direction or an elongated hole extending in the spacing direction, the respective fastening screw for attaching the respective web through the respective passage opening or through the respective slot can be inserted. The cover plate then expediently has for the respective clamping screw at least two spaced apart in the distance direction through holes or extending in the distance direction slot so that the respective clamping screw for connecting the cover plate with the respective side bar through the respective passage opening or through the slot is inserted , As a result, a mechanically simple design and thus easy to use embodiment is created, which offers a high reliability.
Alternativ dazu kann der jeweilige Zwischensteg mittels wenigstens einer Befestigungsschraube an der Basisplatte befestigbar bzw. befestigt sein. Die Basisplatte kann für die jeweilige Befestigungsschraube wenigstens eine Durchgangsöffnung, insbesondere in Form eines Langlochs, aufweisen, durch die die jeweilige Befestigungsschraube zum Befestigen des jeweiligen Zwischenstegs einführbar bzw. eingeführt ist. Die Abdeckplatte kann in diesem Fall für wenigstens eine weitere Spannschraube wenigstens eine Durchgangsöffnung, insbesondere in Form eines Langlochs, aufweisen, durch die die jeweilige weitere Spannschraube zum Verbinden der Abdeckplatte mit dem jeweiligen Zwischensteg einführbar bzw. eingeführt ist. Auch diese Ausführungsform zeichnet sich durch einen einfachen und somit zuverlässig handhabbaren Aufbau aus.Alternatively, the respective intermediate web can be fastened or fastened to the base plate by means of at least one fastening screw. The base plate can have at least one passage opening, in particular in the form of an oblong hole, for the respective fastening screw, through which the respective fastening screw for fastening the respective intermediate web can be introduced or inserted. In this case, the cover plate can have at least one passage opening, in particular in the form of a slot, for at least one further tightening screw, through which the respective further tightening screw for connecting the cover plate to the respective intermediate web can be introduced or inserted. This embodiment is characterized by a simple and thus reliable manageable structure.
Entsprechend einer anderen vorteilhaften Ausführungsform kann vorgesehen sein, dass die wenigstens zwei Abstände dadurch einstellbar sind, dass zumindest einer der Seitenstege exzentrisch an der Basisplatte und an der Abdeckplatte angeordnet ist, derart, dass sich durch Wenden dieses Seitenstegs der Abstand zum anderen Seitensteg verändert. Beispielsweise kann hierzu eine im verstellbaren bzw. wendbaren Seitensteg ausgebildete Gewindeöffnung, die zum Verschrauben des Seitenstegs mit der Basisplatte bzw. mit der Abdeckplatte dient, bezüglich einer dem anderen Seitensteg zugewandten Innenseite und einer vom anderen Steg abgewandten Außenseite außermittig, also exzentrisch angeordnet sein. Durch Wenden dieses wendbaren Seitenstegs werden die Positionen von Innenseite und Außenseite getauscht, wodurch sich automatisch auch ein anderer Abstand gegenüber dem anderen Seitensteg einstellt. Bei dieser Ausführungsform sind keine zusätzlichen Öffnungen in der Basisplatte und in der Abdeckplatte erforderlich.According to another advantageous embodiment it can be provided that the at least two distances are adjustable in that at least one of the side webs is arranged eccentrically on the base plate and on the cover plate, such that the distance to the other side web changes by turning this side web. For example, a threaded opening formed in the adjustable or reversible side web, which serves to screw the side web to the base plate or to the cover plate, can be eccentrically arranged with respect to an inner side facing the other side web and an outer side facing away from the other web. By turning this reversible side bar, the positions of the inside and outside are changed, which automatically sets a different distance from the other side bar. In this embodiment, no additional openings in the base plate and in the cover plate are required.
Entsprechend einer anderen vorteilhaften Ausführungsform können zum Befestigen des jeweiligen Zwischenstegs oder zum Befestigen des jeweiligen verstellbaren Seitenstegs an der Basisplatte zwei Befestigungsschrauben vorgesehen sein, während zum Befestigen der Abdeckplatte am jeweiligen Steg nur eine Spannschraube vorgesehen ist. Hierdurch wird zum einen eine sichere Verankerung des jeweiligen Stegs an der Basisplatte bewirkt, während gleichzeitig das Lösen und Festziehen der Abdeckplatte vereinfacht wird, da hierzu weniger Spannschrauben betätigt werden müssen.According to another advantageous embodiment, two fastening screws can be provided for fastening the respective intermediate web or for attaching the respective adjustable side web to the base plate, while only one clamping screw is provided for fastening the cover plate on the respective web. As a result, on the one hand a secure anchoring of the respective web on the base plate is effected, while at the same time the loosening and tightening of the cover plate is simplified, since this less clamping screws must be pressed.
Entsprechend einer vorteilhaften Ausführungsform kann die jeweilige Befestigungsschraube in der jeweiligen Durchgangsöffnung oder im jeweiligen Langloch versenkt angeordnet sein. Hierdurch kann die Gefahr einer Beschädigung der jeweiligen Schraube beim Abstellen der Gabelklemme bzw. beim Absetzen der Gabel auf einem Boden reduziert werden.According to an advantageous embodiment, the respective fastening screw can be sunk in the respective passage opening or in the respective slot. This can reduce the risk of damage to the respective screw when parking the fork clamp or when placing the fork on a floor.
Gemäß einer anderen vorteilhaften Ausführungsform kann vorgesehen sein, dass nur einer der Seitenstege in der Abstandsrichtung verstellbar ist, während für den anderen Seitensteg nur eine Position vorgesehen ist. Auch diese Maßnahme vereinfacht die Handhabung der Gabelklemme.According to another advantageous embodiment it can be provided that only one of the side webs in the distance direction is adjustable, while only one position is provided for the other side web. This measure also simplifies the handling of the fork clamp.
Entsprechend einer vorteilhaften Weiterbildung kann auch der nicht verstellbare Seitensteg mittels wenigstens einer Befestigungsschraube an der Basisplatte befestigt sein. Alternativ kann der nicht verstellbare Seitensteg auch mit der Basisplatte verschweißt sein oder mit der Basisplatte aus einem Stück hergestellt sein. Auch hier kann die jeweilige Befestigungsschraube in der Basisplatte versenkt angeordnet sein. Ebenso können auch hier zwei Befestigungsschrauben zum Festlegen des Seitenstegs an der Basisplatte genutzt werden.According to an advantageous development, the non-adjustable side bar can also be fastened to the base plate by means of at least one fastening screw. Alternatively, the non-adjustable side bar may also be welded to the base plate or made with the base plate in one piece. Again, the respective fastening screw can be recessed in the base plate. Likewise, two fixing screws for fixing the side bar to the base plate can also be used here.
Entsprechend einer anderen vorteilhaften Ausführungsform kann die Gabelklemme mit wenigstens einer Zurröse ausgestattet sein, die an der Abdeckplatte an einer von der Basisplatte abgewandten Seite oder aber an der Basisplatte an einer von der Abdeckplatte abgewandten Seite angeordnet ist. Mit Hilfe einer derartigen Zurröse lässt sich ein geeignetes Zurrmittel, wie z.B. ein Zurrgurt, ein Zurrseil oder eine Zurrkette, besonders einfach an der Gabelklemme anbringen, um so die auf der Gabel abgelegte Ladung zu sichern.According to another advantageous embodiment, the fork clamp can be equipped with at least one lashing, which is arranged on the cover plate on a side facing away from the base plate side or on the base plate on a side facing away from the cover plate. With the help of such lashing a suitable lashing means, such as. attach a lashing strap, a lashing rope or a lashing chain, particularly easy to the fork clamp, so as to secure the load deposited on the fork.
Entsprechend einer vorteilhaften Weiterbildung können für die Zurröse wenigstens bezüglich der Abstandsrichtung unterschiedliche Positionen an der Abdeck-platte oder an der Basisplatte einstellbar sein. Hierdurch ist es insbesondere möglich, für unterschiedliche Abstände zwischen den Seitenstegen bzw. für die Verwendung der Gabelklemme mit oder ohne Zwischensteg, jeweils eine mittige Belastung der Gabelklemme zu erreichen, indem die Zurröse etwa mittig zwischen den beiden, den Abstand zur Aufnahme des jeweiligen Zinkens definierenden Stegen angeordnet wird. Insbesondere befindet sich die Zurröse dann mittig zwischen den Seitenstegen oder mittig zwischen dem Zwischensteg und einem der Seitenstege.According to an advantageous development, different positions on the cover plate or on the base plate can be adjustable for the lashing at least with respect to the distance direction. This makes it possible, in particular for different distances between the side bars or for the use of the fork clamp with or without gutter, each to achieve a central load of the fork clamp by the lashing approximately midway between the two, defining the distance to receive the respective tine Webs is arranged. In particular, the lashing is then centrally between the side bars or centrally between the gutter and one of the side bars.
Gemäß einer anderen vorteilhaften Weiterbildung kann die Zurröse um eine Drehachse drehbar sein. Hierzu kann die Zurröse eine fest mit der Basisplatte bzw. mit der Abdeckplatte verschraubbare Konsole aufweisen, an der ein Ringkörper verdrehbar gelagert ist, der die eigentliche Öse definiert.According to another advantageous development, the lashing ring can be rotatable about an axis of rotation. For this purpose, the lashing a permanently screwed to the base plate or with the cover plate console on which an annular body is rotatably mounted, which defines the actual eye.
Des weiteren kann vorgesehen sein, dass an der Abdeckplatte bzw. an der Basisplatte wenigstens zwei unterschiedliche Befestigungsstellen, vorzugsweise Schraubstellen, vorgesehen sind, um zwei unterschiedliche Zurrösen wahlweise anbringen zu können. Unterschiedliche Zurrösen können sich beispielsweise durch unterschiedliche Gewindegrößen ihrer Verschraubungen voneinander unterscheiden.Furthermore, it can be provided that at least two different fastening points, preferably screw points, are provided on the cover plate or on the base plate in order to be able to selectively attach two different lashing eyes. Different lashing eyes can differ, for example, from each other by different thread sizes of their glands.
Zusätzlich oder alternativ kann vorgesehen sein, die jeweilige Zurröse bezüglich einer parallel zur Abstandsrichtung verlaufenden Längsrichtung der Gabelklemme außermittig anzuordnen. Hierdurch kann beim Verzurren gezielt ein Kippmoment eingeleitet werden, das bei einer Beweglichkeit der Gabelklemme relativ zum Zinken zu einem Verkanten der Gabelklemme am Zinken führen kann. Hierdurch kann eine Haltekraft, mit der die Gabelklemme am Zinken festgehalten wird, erzeugt bzw. verstärkt werden.Additionally or alternatively, it may be provided to arrange the respective lashing off-center with respect to a longitudinal direction of the fork clamp extending parallel to the spacing direction. As a result, a tilting moment can be introduced specifically during lashing, which can lead to a tilting of the fork clamp on the prong when the fork clamp is movable relative to the prong. As a result, a holding force with which the fork clamp is held on the tine, generated or amplified.
Eine erfindungsgemäße Hubeinrichtung, die insbesondere an einem Gabelstapler angeordnet sein kann, umfasst eine Gabel, die wenigstens zwei Zinken besitzt, sowie wenigstens eine Gabelklemme der vorstehend beschriebenen Art. Eine Höhe der Stege, also der Seitenstege und ggf. des Zwischenstegs, mit der sie von der Basisplatte abstehen, ist dabei kleiner als eine Dicke der Zinken in Bereichen, die für die Befestigung der Gabelklemme vorgesehen ist. Das bedeutet, die jeweilige Gabelklemme ist speziell auf die Dicke der Zinken abgestimmt. Üblicherweise besitzen die Zinken eine genormte Dicke, wobei unterschiedliche Gabeln mit unterschiedlichen Zinken im Markt verwendet werden. Zweckmäßig ist die Höhe der Stege so gewählt, dass auch bei den Zinken mit der kleinsten Dicke diese Dicke größer ist als die Höhe der Stege. Durch diese Maßnahme wird gewährleistet, dass beim Festziehen der Spannschrauben stets eine Klemmkraft erzeugt wird, die den jeweiligen Zinken zwischen der Basisplatte und der Abdeckplatte verklemmt, wodurch eine sehr hohe Haltekraft erzeugt werden kann, die die jeweilige Gabelklemme an dem jeweiligen Zinken fixiert, insbesondere in der Längsrichtung des jeweiligen Zinkens.A lifting device according to the invention, which may be arranged in particular on a forklift, comprises a fork having at least two prongs, and at least one fork clamp of the type described above. A height of the webs, so the side bars and possibly the gutter, with which they protrude the base plate is smaller than a thickness of the tines in areas, which is intended for the attachment of the fork clamp. This means that the respective fork clamp is specially adapted to the thickness of the tines. Usually, the tines have a standard thickness, with different forks are used with different prongs in the market. Suitably, the height of the webs is selected so that even with the tines with the smallest thickness, this thickness is greater than the height of the webs. By this measure, it is ensured that when tightening the clamping screws always a clamping force is generated, which jammed the respective prongs between the base plate and the cover plate, whereby a very high holding force can be generated, which fixes the respective fork clamp to the respective prongs, in particular the longitudinal direction of the respective tine.
Durch die Auswahl der Höhe der Stege abhängig von den üblichen im Markt befindlichen Zinken, lässt sich die Gabelklemme universal bei mehreren unterschiedlichen Gabeln nutzen.By selecting the height of the bars depending on the usual tines available in the market, the fork clamp can be used universally with several different forks.
Ein erfindungsgemäßes Verzurrungsset, das zum Verzurren eines Ladeguts an einer Gabel einer Hubeinrichtung verwendet werden kann, umfasst zumindest eine Gabelklemme der vorstehend beschriebenen Art. Außerdem umfasst das Verzurrungsset zumindest eine Gabellasche, die auf einen Zinken der Gabel aufsteckbar ist, und/oder zumindest einen Zurrgurt, der durch eine Zurröse der Gabelklemme durchführbar ist. Sofern das Verzurrungsset sowohl wenigstens eine Gabellasche als auch wenigstens einen Zurrgurt umfasst, ist der Zurrgurt zweckmäßig auch durch eine Zurröse der Gabellasche durchführbar. Die Gabellasche unterscheidet sich von der Gabelklemme dadurch, dass die Gabellasche zwar ebenso wie die Gabelklemme auf einen Zinken einer Gabel aufsteckbar ist, jedoch nicht daran festlegbar ist. Insbesondere kann eine derartige Gabellasche aus einem Stück hergestellt sein, während die Gabelklemme mehrteilig ausgestaltet ist.An inventive lashing set, which can be used for lashing a load on a fork of a lifting device, comprises at least one fork clamp of the type described above. In addition, the lashing set comprises at least one fork lug which can be attached to a prong of the fork, and / or at least one lashing strap which is feasible by a lashing of the fork clamp. If the lashing set comprises both at least one fork lug and at least one lashing strap, the lashing strap can also be carried out expediently by a lashing loop of the fork lug. The fork strap differs from the fork clamp in that although the fork strap, like the fork clamp, can be attached to a fork of a fork, it can not be attached to it. In particular, such a fork strap can be made in one piece, while the fork clamp is designed in several parts.
