Die gebräuchlichen offenen S-Haken für Aufzüge bei Bauten oder dergl. haben den Nachtheil, dafs sich die zu hebenden Lasten, wie Steine, Hölzer und dergl., beim Anstofsen an Wände oder Vorsprünge leicht loslösen und herabstürzen.The common open S-hooks for elevators in buildings or the like. Have the Disadvantage that the loads to be lifted, such as stones, wood, and the like, are inconsistent with the impact Easily detach from walls or protrusions and fall down.
In der Fig. 1 ist die Seitenansicht und in der Fig. 2 der Querschnitt eines Sicherheitshakens dargestellt, bei welchem ein unbeabsichtigtes Loslösen der gehobenen Last unmöglich ist.1 shows the side view and FIG. 2 shows the cross section of a safety hook in which an unintentional Detaching the lifted load is impossible.
Dieser Sicherheitshaken besteht aus einem S-Haken α, dessen obere Hälfte zum Einhängen des Hebeseiles dient, während an die untere Hälfte die Last gehängt wird. Die beiden Enden dieses S-Hakens sind nach auswärts gebogen und mit Oesen b und c versehen, welche zur Aufnahme eines Riegels d dienen. An diesem Riegel d ist eine Feder e angeordnet, deren Kerbe f zum Feststellen des Riegels d durch Einschnappen in die Oese b dient. Der Riegel d kann mittels einer Kette oder dergl. mit dem S-Haken untrennbar verbunden sein.This safety hook consists of an S-hook α, the upper half of which is used to hang the lifting rope, while the load is hung on the lower half. The two ends of this S-hook are bent outwards and provided with eyelets b and c , which serve to accommodate a bolt d. A spring e is arranged on this bolt d , the notch f of which is used to fix the bolt d by snapping it into the eyelet b . The bolt d can be inseparably connected to the S-hook by means of a chain or the like.
Beim Gebrauche dieses Sicherheitshakens werden zunächst das Aufzugsseil und das Lastseil in die offenen Haken eingehängt. Dann wird der Haken durch Einschieben des federnden Riegels d in die Oesen b und c versperrt, so dafs sich weder das Aufzugsseil noch das Lastseil selbst beim Auftreten von Stöfsen oder Schwingungen vom S-Haken loslösen können. Sollen jedoch die Seile absichtlich gelöst werden, so genügt ein Druck von der Hand des Arbeiters auf die Feder e, um die Sperrung des Riegels d zu öffnen, welcher dann leicht aus den Oesen b und c herausgezogen werden kann.When using this safety hook, the elevator rope and the load rope are first hooked into the open hooks. Then the hook is locked by pushing the resilient bolt d into the eyelets b and c , so that neither the elevator rope nor the load rope can detach from the S-hook even if bumps or vibrations occur. However, if the ropes are to be loosened on purpose, all that is needed is pressure from the worker's hand on the spring e to open the locking mechanism of the bolt d , which can then be easily pulled out of the eyelets b and c .
