Abstract

The safety device for securing a load to a crane-hook, consists of a flat metal plate (1) which is attached to two triangular side flanges (2) made of an elastomeric material. The device is attached to the crane hook by fasteners (4,5) at each end of one side of each side flange so that the metal plate extends across the open part of the hook at an angle of about 45 deg. When a load is attached to the hook the metal part (1) is swung downwards and the side flanges bulge outwards. When the load is in place the metal part (1) is swung back to its original position by the resilience of the side flanges (2). USE - Load safety device for crane hooks.

Description

Die Erfindung betrifft ein Element zur Sicherung von in Kranhaken eingebrachte Anschlagmittel derart, daß ein Herausnehmen des Anschlagmittels nur nach Betätigung der Sicherung möglich ist.The invention relates to an element for securing in Crane hooks brought in such a way that a Only remove the lifting gear after actuating the Backup is possible.

Die bisher gebräuchlichen Kranhakensicherungen sind aus Metall, vornehmlich aus gebogenem Stahlblech, die Rück­ stellwirkung wird mittels einer Metallfeder erzielt. Die Verwendung des Metallbleches hat zur Folge, daß durch äußere Einwirkung die Flanken des Sicherungsbleches ver­ biegen und das Sicherungselement in der hinteren Stellung blockiert wird. Durch das Blockieren wird das Element unwirksam. Als Folge der Verwendung einer Metallfeder und der Verwendung eines reinen Metallsicherungselementes ist an der Auftreffstelle Sicherungselement Kranhaken­ spitze eine Klemmstelle, an der sich das Bedienungsper­ sonal des Kranes die Finger klemmen kann.The crane hook safety devices that have been used up to now are out Metal, mainly from bent sheet steel, the back positioning effect is achieved by means of a metal spring. The Use of the metal sheet has the consequence that external influence ver the flanks of the locking plate bend and the securing element in the rear position is blocked. By blocking the element ineffective. As a result of using a metal spring and the use of a pure metal fuse element is at the point of impact safety element crane hook tip a terminal point at which the operator can clamp the fingers of the crane.

Der Erfindung liegt die Aufgabe zugrunde, das Sicherungs­ system derart zuverlässiger zu gestalten, daß ein Blockie­ ren der Sicherung durch vorliegende Flanken nicht möglich ist und die Gefahr des Klemmens erheblich vermindert wird.The invention has for its object the backup system so reliable that a blockage cannot be secured by existing edges is and the risk of jamming is significantly reduced.

Die Lösung der gestellten Aufgabe besteht darin, daß das Sicherungselement der eingangs genannten Art teilweise aus einem elastischen und teilweise aus einem festen Werk­ stoff gefertigt wird. Der elastische Werkstoff bringt die Rückstellkraft auf und der feste Werkstoff erbringt die Sicherungsleistung. The solution to the problem is that the securing element of the type mentioned in part from an elastic and partly from a solid work fabric is made. The elastic material brings the restoring force and the solid material provides the security deposit.  

In Weiterbildung der Erfindung ist der elastische Werk­ stoff ein Elastomer, vorteilhafterweise Gummi, und der feste Werkstoff Metall. Das Metall wird zweckmäßigerweise in das elastomere Material eingebettet, damit eine innige Verbindung zwischen beiden entsteht, und die potentielle Klemmstelle zwischen Kranhakenspitze und Sicherungselement entschärft wird. Der reine Elastomerteil des Sicherungs­ elementes wird so angeordnet, daß bei Betätigung der Kran­ hakensicherung eine Verformung des reinen Elastomerteiles eintritt, diese Verformung bewirkt nach Betätigen der Sicherung eine Rückstellung der Sicherung in die Ausgangs­ lage.In a further development of the invention is the elastic work fabric an elastomer, advantageously rubber, and the solid material metal. The metal is convenient embedded in the elastomeric material, so that an intimate Connection between the two arises, and the potential Clamping point between the crane hook tip and securing element is defused. The pure elastomer part of the fuse element is arranged so that when operating the crane hook securing a deformation of the pure elastomer part occurs, this deformation causes after pressing the Fuse a reset of the fuse in the output location.

Die Erfindung ist anhand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.

Fig. 3 Die Kranhakensicherung aus Fig. 1 betätigt. Fig. 3 actuated the crane hook safety device from Fig. 1.

Wie aus Fig. 1 und 2 bei dem hier gewählten Ausführungs­ beispiel zu ersehen, ist das Metallelement 1 so angeord­ net und geformt, daß es die Schutzwirkung erbringt. Die Flanken 2 des Sicherungselementes bestehen aus Elastomer­ material, vorteilhafterweise aus Gummi. Sie sind in diesem Ausführungsbeispiel im unteren Teil fest mit dem Kranhaken 3 verbunden 4. Der obere Befestigungspunkt 5 des Sicherungs­ elementes ist eine drehbare Lagerung des mit den Gummi­ flanken 2 verbundenen Metallelementes. Bei Betätigung der Sicherung dreht sich das Metallelement um die Lagerstelle 5 und die Flanken 2 verformen sich, gleichzeitig wird Raum für das Einlegen bzw. Entnehmen des Anschlagmittels 6 (vgl. Fig. 3) freigegeben. Wird das Sicherungselement ent­ lastet, bewegt es sich in diesem Ausführungsbeispiel auf­ grund der verformten Flanken in seine Ausgangslage zurück. Dabei ist die Klemmstelle 6, wie hier ersichtlich, durch einseitigen Gummibelag erheblich entschärft.As can be seen from FIGS. 1 and 2 in the embodiment chosen here, the metal element 1 is arranged and shaped in such a way that it provides the protective effect. The flanks 2 of the securing element consist of elastomer material, advantageously of rubber. In this exemplary embodiment, they are firmly connected to the crane hook 3 in the lower part 4 . The upper attachment point 5 of the securing element is a rotatable mounting of the metal element connected to the rubber flanks 2 . When the safety device is actuated, the metal element rotates around the bearing point 5 and the flanks 2 deform, at the same time space for the insertion or removal of the slinging means 6 (cf. FIG. 3) is released. If the securing element is relieved, it moves back into its starting position in this exemplary embodiment due to the deformed flanks. The clamping point 6 , as can be seen here, is considerably defused by one-sided rubber covering.
