Gemäss der Erfindung sind die freien Enden der Winkelhebel, welche die Greiferschaufeln tragen, durch Schubstangen an das Steuerseil angeschlossen, welche Schubstangen Rollen eines Flaschenzuges tragen, dessen zugehöriger Rollensatz in dem zur Lagerung der Greiferschaufel-Drehachsen dienenden Schilde angeordnet ist. 



   In der Zeichnung ist eine beispielsweise Ausführungsform des Gegenstandes der Erfindung veranschaulicht, und zwar zeigen die Fig. 1 bis 3 den Greifer in Vorderansicht geschlossen, im Grundriss und in Vorderansicht offen. 



   Die Schaufeln a und al sind an Doppelhebeln b, c und   b1   und   ei   befestigt, die um Punkte d und   d)   eines Schildes e drehbar sind. An den   Hebeln c, f,   greifen mittels Zugstangen fund/1

 dimensions and therefore great performance of the gripper is achieved. According to the invention, the free ends of the angle levers that carry the grab shovels are connected to the control cable by push rods, which push rods carry rollers of a pulley block, the associated roller set of which is arranged in the shields used to support the grab shovel axes of rotation.



   In the drawing, an exemplary embodiment of the subject matter of the invention is illustrated, namely FIGS. 1 to 3 show the gripper closed in front view, open in plan and front view.



   The blades a and al are attached to double levers b, c and b1 and ei, which are rotatable about points d and d) of a shield e. The levers c, f, grip by means of tie rods fund / 1

 Bottle rolls f, Tl are surrounded by protective plates in such a way that when the gripper is full, i.e. closed, the ropes or chains of the bottle are completely protected.



   The gripper works as follows:

   the control cables g, g1 are dead. If the empty or full gripper is to be opened in any position, the control ropes or chains are held or tightened while the hoisting ropes h. h1 can be eased. The whole weight of the gripper is now hanging in the

 of the gripper with a multiple of the cable pull in h, h1 due to the number of bottle rolls r, r1, whereupon the full gripper is lifted. Guard plates protect the ropes or chains of the bottle from damage by the conveyed goods. The filling gripper takes the

   The self-gripper designed according to the present invention allows large mouth widths to be achieved when the gripper is open by the action of the angle lever c, ('1' by which the entire gripper weight is used to () open the shovels. This results in a small gripper-

 causes which would otherwise prevent a sufficient closure of the blades.
