Description

Es ist beobachtet worden, dab bei unvorsichtigem Herablassen oder Emporheben von Lasten mittels Kranen der Kranhaken aus seiner senkrechten Lage gebracht werden kann, z. B. wenn er in höchster Stellung oben anschlägt und sich infolgedessen schräg stellt, dann kann die Last abgleiten und zu Boden stürzen. Um dies zu verhüten, wird das Maul des Kranhakens nach dem EinhängenIt has been observed that when the person is lowered or lifted carelessly The crane hook can be brought out of its vertical position by loads by means of cranes can e.g. B. when he hits the top in the highest position and as a result obliquely then the load can slide off and fall to the ground. To prevent this, this will The mouth of the crane hook after hanging

ίο der Last durch ein Sperrglied geschlossen, das in seiner Lage in der Regel durch Federn, Gewichte oder die eingehängte Last gesichert wird. Diese bisher bekannten Sicherungen sind entweder unsicher in dejr Wirkung oder umständlich beim Gebrauch.ίο the load closed by a locking element that usually secured in its position by springs, weights or the suspended load will. These previously known fuses are either unsafe in their effect or awkward to use.

Nach der Erfindung wird die Sicherung des Sperrgliedes durch ein in ihm angeordnetes Exzenter bewirkt. Dadurch wird eine in der Bauart und Handhabung einfache Sicherung erzielt, die den weiteren Vorteil hat, daß sie beim Einlegen des Sperrgliedes selbsttätig in Wirkung tritt.According to the invention, the locking member is secured by a arranged in it Eccentric causes. As a result, a fuse that is simple in terms of design and handling is achieved, which has the further advantage has that it automatically comes into effect when the locking member is inserted.

Der Gegenstand der Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt. Abb. ι und 2 zeigen die Sicherung gemäß der Erfindung in Seitenansicht und Abb. 3 in Vorderansicht.The object of the invention is shown in the drawing in an exemplary embodiment. Fig. Ι and 2 show the fuse according to the invention in side view and Fig. 3 in front view.

Am Kranhakenende ist um einen Bolzen a drehbar die doppellaschige Sperrklinke b mit dem zwischen den Laschen angeordnetenAt the end of the crane hook, the double-lashed pawl b with the pawl arranged between the lugs can be rotated about a bolt a

Exzenterhebel c befestigt, der um einen beide Laschen verbindenden Bolzen d drehbar ist und in die am Kranhakenenjde befindliche;, dem Exzenter entsprechende Rundung beim Schließen des Spejrhakens selbsttätig einfällt, wodurch derselbe festgestellt ist.Eccentric lever c attached, which is rotatable about a bolt d connecting the two straps and automatically falls into the curve corresponding to the eccentric when the spear hook is closed, whereby the same is fixed.

In Abb. 2 ist der Haken mit geöffnete?· Sicherung dargestellt. Nachdem die Last mittels des Ringest in den Kranhaken./ eingehängt is^Jj, wird die Sperrklinke & gegen den Hakenschaft gelegt, und der Exzenterhebel c stellt vollkommen selbsttätig die Sperrklinke fest. Ein Bewegen der letzteren ohne Anjheben des Exzenterhebels und ein Herausgleiten der Last aus dem Haken ist nunmehr unmöglich. Im geöffneten Zustande des Hakens sind keinerlei Hindernisse vorhanden, die die Entfernung des Lastringes e erschweren könnten,In Fig. 2, the hook is shown with the? · Fuse open. After the load suspended by means of the meddle in the Kranhaken./ is ^ Jj, is placed the pawl & against the hook shank, and the cam lever c is completely automatically determines the pawl. Moving the latter without lifting the eccentric lever and sliding the load out of the hook is now impossible. When the hook is open, there are no obstacles that could complicate the removal of the load ring e,
