Bei Heuaufzügen und ähnlichen mit Greifern arbeitenden Aufzügen steht der Bedienende auf dem abzuladenden Wagen, drückt den Greifer in das abzuladende Gut und schaltet den Aufzug auf Hochzug ein. Bei dem unsicheren Stand auf dem Heuwagen gerät der Bedienende in Versuchung, sich an dem Seil, an dem der noch unten befindliche Greifer hängt, festzuhalten, und soIn the case of hay lifts and similar lifts that work with grippers, the operator is standing on the wagon to be unloaded, presses the gripper into the goods to be unloaded and switches the elevator on. at The unsteady stance on the hay wagon tempts the operator to grab the rope on which the one below is still attached Claw hangs, to hold on, and such ίο kommt er bei hochgehendem Greifer in die Gefahr, mit seiner Hand zwischen die Seilrolle und das Seil hineinzugeraten, so daß schwere Verletzungen nicht selten sind.
Es sind zwar Abstreifer bekannt, die fest an dem Seilrollengehäuse befestigt sind (Abb. ι und 2 der Zeichnung). Bei Verwendung dieser Abstreifer scheuert jedoch das Seil beim Schwanken der Last oder bei Änderungen des Winkels zwischen auf- und
If the gripper goes up, there is a risk of his hand getting between the pulley and the rope, so that serious injuries are not uncommon.
There are known wipers that are firmly attached to the pulley housing (Fig. Ι and 2 of the drawing). When using this scraper, however, the rope rubs when the load sways or when the angle changes between up and
ao ablaufendem Seiltrum an dem Abstreifer, da die Bohrung, um genügend Schutz zu gewähren, im Durchmesser nicht wesentlich größer sein darf als der Seildurchmesser.ao running rope run on the scraper, because the hole to provide sufficient protection, the diameter must not be significantly larger than the rope diameter. Dieser Übelstand soll gemäß der Erfindung vermieden werden, daß die Abstreifer drehbar um die Achse der Rolle oder um eine in deren unmittelbaren Nähe liegenden Achse angeordnet werden, so daß sie sich der jeweiligen Auflaufrichtung des Seiles entsprechend einstellen können. In den Abb. 3, 4 der Zeichnung ist eine Rolle mit in dieser Weise angeordneten Abstreifern bei verschiedenen Seilauf lauf winkeln dargestellt. Die Abb. S gibt eine Seitenansicht der Rolle mit dem Abstreifer.This drawback is to be avoided according to the invention that the scrapers are rotatable around the axis of the roller or around an axis lying in the immediate vicinity thereof, so that they are the respective Can adjust the run-up direction of the rope accordingly. In Figs. 3, 4 of the drawing, a role is included in this Way arranged scrapers at different Seilauf running angles shown. the Fig. S gives a side view of the roller with the scraper. Paten τ-Anspruch:Sponsorship τ claim: Seilrolle für Heu- oder andere Aufzüge mit Abstreifern für die Hände, dadurch gekennzeichnet, daß die Abstreifer um die Achse der Rolle oder um eine in unmittelbarer Nähe dieser Achse liegende Achse drehbar sind, so daß der Abstreifer der jeweiligen Auflaufrichtung des Seiles auf die Rolle sich anpassen kann.Pulley for hay or other lifts with scrapers for the hands, thereby characterized in that the scraper around the axis of the roller or around one in the immediate Near this axis lying axis are rotatable, so that the scraper of the respective run-up direction of the rope the role can adapt.
