Description
Lasthaken für ein- oder mehrsträngiges GurtengehängeLoad hook for single or multi-strand sling
Die vorliegende Erfindung betrifft einen Lasthaken fUr ein-oder mehrsträngiges Gurtengehänge.The present invention relates to a load hook for a single or multiple leg Sling hangers.
Die bekannten Lasthaken für ein- oder mehrsträngiges Gurtengehänge bestehen aus einer Rundöse mit anschliessendem offenem Rundhaken. Diese Lasthaken sind im allgemeinen geschweisst und daher ihre spezifische Tragfähigkeit, bezogen auf die gefährdeten Hakenquerschnitte, bescheiden. Auch sind sie unangenehm im Handhaben und weisen, was wohl den grössten Nachteil darstellt, keine abwickelbaren Auflageflächen für die Gurten auf, sondern sind räumlich gebogene, nicht abwickelbare Flächen. Dies strapaziert die Gurten unnötigerweise und führt zu frühzeitiger Abnützung und Reissgefahr.The well-known load hook for single or multi-strand sling consist of a round eyelet followed by an open round hook. These load hooks are generally welded and therefore related to their specific load-bearing capacity on the endangered hook cross-sections, modest. They are also uncomfortable to use and, which is probably the greatest disadvantage, have no developable support surfaces for the belts, but are spatially curved, non-developable surfaces. This unnecessarily strains the belts and leads to premature wear and tear Risk of tearing.
Die vorliegende Aufgabe besteht in der Schaffung eines Lasthakens, welcher, bei gleicher kritischer Querschnittsgrösse, höhere spezifische Belastbarkeit aufweist und so beschaffen ist, dass die Gurtengehänge durch den Haken nicht unnütz zusätzlich belastet werden.The task at hand is to create a load hook, which, with the same critical cross-sectional size, has a higher specific load capacity and is made in such a way that the sling is not useless due to the hook are additionally charged.
Ein derartiger erfindungsgemässer Lasthaken zeichnet sich dadurch aus, dass er im Gesenk geschmiedet ist, und dass er für die Gurten im Belastungsfall im wesentlichen zylindermantelartige Auflageflächen aufweist.Such a load hook according to the invention is characterized by this that it is drop forged and that it is used for the belts in the event of a load has essentially cylinder jacket-like support surfaces.
Der Erfindungsgegenstand wird anschliessend anhand einer Zeichnung erläutert.The subject of the invention is then based on a drawing explained.
Es zeigen: Fig. 1 eine Seitenansicht eines Lasthakens, Fig. 2 einen Schnitt gemäss Schnittlinie II - II durch den Lasthaken nach Fig. 1.1 shows a side view of a load hook, FIG. 2 shows one Section along section line II - II through the load hook according to FIG. 1.
Ein im Gesenk geschmiedeter, d.h. nicht geschweisster und gebogener Lasthaken 1 weist eine geschlossene Oese 3 auf, mit einem Umschlingungsarm 4 für die Aufnahme einer geschlauften Gurte 19 sowie mit einem Seitenarm 5 und einem Basisarm 6, welcher konsolenartig verbreitert ist. Die Auflagefläche 8 des Umschlingungsarmes 4 ist als Mantelfläche eines Kreiszylinders ausgebildet, wie dies in Fig. 2 ersichtlich ist. Unter der Oese 3 befindet sich eine offene Oese 10 mit einem Umschlingungsarm 11, einem Seitenarm 12 und an diesem, als Fortsetzung ausgebildet, eine Sicherungsnase 13. Zwischen den beiden Oesen 3 und 10 ist ein Einführkanal 15 für das Einführen einer eingezogenen Gurte 20 vorgesehen.One that is drop forged, i.e. not welded and bent Load hook 1 has a closed eyelet 3, with a wrap arm 4 for the inclusion of a looped belt 19 and with a side arm 5 and a base arm 6, which is widened like a console. The support surface 8 of the wrap arm 4 is designed as a lateral surface of a circular cylinder, as can be seen in FIG is. Under the eyelet 3 there is an open eyelet 10 with a wrap arm 11, a side arm 12 and on this, designed as a continuation, a locking nose 13. Between the two eyelets 3 and 10 is an insertion channel 15 for insertion a retracted belt 20 is provided.
Die Auflagefläche 16 für die Gurte 20 bei belastetem Gehänge ist ebenfalls kreiszylinderförmig. Die Breite der Oesen 3 und 10 entspricht der Breite der Gurten 19 und 20, so dass diese im belasteten Zustand seitlich geführt sind. In entlastetem Zustand verhindert die Sicherungsnase 13 ein unbeabsichtigtes Hinausgleiten des Gurtes 20 durch den EinfGhrkanal 15.The support surface 16 for the straps 20 when the hanger is loaded is also circular cylindrical. The width of the eyelets 3 and 10 corresponds to the width of the belts 19 and 20, so that they are guided laterally in the loaded state. In relieved State prevents the locking lug 13 from accidentally sliding out of the Belt 20 through the insertion channel 15.
Eine seitliche Handhabe 17, welche den Lasthaken 1 auf der Seite entsprechend den kritisch beanspruchten Zonen verstärkt, erlaubt ein leichteres Einziehen der Gurte 20 durch Festhalten des Lasthakens 1 an der seitlichen Handhabe 17.A side handle 17, which the load hook 1 on the side accordingly the critically stressed areas reinforced, allows an easier drawing in of the Straps 20 by holding the load hook 1 on the side handle 17.
Dieser Lasthaken 1 ist nicht nur in sich selbst für die Kräfteaufnahme und die Spannungsverteilungen optimal gestaltet, sondern er ist auch bezüglich Gurtengehängeschonung, was Auflageflächen und Führung betrifft, optimal. In diesem Sinne wirken auch die zueinander parallel angeordneten Auflageflächen 8 und 16, welche dafür sorgen, dass die geschlaufte Gurte 19 und die eingezogene Gurte 20 in gemeinsamer Flucht verlaufen.This load hook 1 is not only in itself for absorbing forces and the tension distribution is optimally designed, but it is also in terms of belt suspension protection, What Contact surfaces and guidance are optimal. In this sense the supporting surfaces 8 and 16, which are arranged parallel to one another, also act ensure that the looped straps 19 and the drawn-in straps 20 in common Escape get lost.
