Description
Beim Heben von Lasten ereignen sich sehr leicht dadurch Unfälle, daß die Last oder die die Last tragenden Schlingen aus dem Hakenmaul herausgleiten. Um dies zu vierhindern, hat man die Lasthaken bereits mit Sicherungsverschlüssen versehen. So ist z. B. vorgeschlagen worden, auf dem Schaft des Hakens eine Büchse in einer Schraubenlinie zu führen, die mit einem Ansatz im gesenkten 7axstand die Hakenöffnung verschließt. Weiter ist bereits vorgeschlagen worden, um den Hakenschaft einen Ring zu legen, mit dem ein Sperrhebel gelenkig verbunden- ist. Die Erfindung bezieht sich auf einen Hakenver-Schluß dieser Art. Sie hat gegenüber den bekannten Einrichtungen den Vorteil, daß der Verschluß sich auch nachträglich noch bequem an jeden Haken anbringen läßt und im Betrieb nicht in die Hakenöffnung selbst hineinragt. Die Erfindung besteht darin, daß das Sicherungsglied an seinem Ende mit einem über die Hakenspitze legbaren, an der Hakenspitze durch einen Splint sicherbaren, in der Verschlußstellung außerhalb der Hakenöffnung liegenden Überwurf gelenkig verbunden ist.When lifting loads, accidents occur very easily because the load or the loops carrying the load slide out of the hook mouth. To prevent this from happening, the load hooks have already been fitted with safety locks. So is z. B. has been proposed to lead a bushing in a helical line on the shank of the hook that closes the hook opening with an approach in the lowered 7ax. It has also already been proposed to put a ring on the hook shaft with which a locking lever is articulated. The invention relates to a hook closure of this type. It has the advantage over the known devices that the closure can also be easily attached to any hook afterwards and does not protrude into the hook opening itself during operation. The invention consists in that the securing member is articulated at its end to a cover that can be placed over the hook tip and secured at the hook tip by a cotter pin, in the closed position outside the hook opening.
Der in der Zeichnung dargestellte Hakenverschluß besteht aus dem ein- oder mehrteiligen Glieds, das mit einem um den Hakenschaft drehbaren Ring# bei c gelenkig verbunden'ist und dessen Ende über der Hakenspitze bei d mit einem Überwurfe gelenkig verbunden ist. Dieser Überwurf legt sich über die außerhalb der Hakenöffnung angebrachte Nase/, der Splint £ dient zur Sicherung. Die punktierte Einzeichnung zeigt das Verschlußglied bei geöffnetem Haken.The hook fastener shown in the drawing consists of the one-part or multi-part link which is articulated at c with a ring # rotatable around the hook shaft and the end of which is articulated to a union above the tip of the hook at d . This cover is placed over the nose / attached outside of the hook opening, the split pin £ is used for securing. The dotted line shows the closure member with the hook open.
