Abstract
Eine an einem Förderseil anbringbare Lastaufnahmevorrichtung (1) besitzt zur Aufnahme eines Anschlagmittels eine durch einen Haltebügel (11) an einem Träger (2) verschließbare Halterungsausnehmung (30). Der Haltebügel (11) ist durch einen Riegel (22) sperrbar, der von einem in einem Hydraulikzylinder geführten, federbelasteten Kolben (4) beim Anheben einer Last im Sperrsinn betätigt wird. Dabei sind die beiden Zylinderräume durch einen von einer nur in einer Richtung wirkenden Lippendichtung (6) des Kolbens (4) freigegebenen Spalt zwischen Zylinder und Kolben (4) verbunden. Für die Rückstellung des Kolbens (4) zur Freigabe des Haltebügels (11) durch den Riegel (22) zum Absetzen der Last erfolgt eine Verbindung der Zylinderräume über eine im Durchfluß regelbare Leitung (12, 13). Vorteilhafte Ausbildungen der Durchflußregelung der Leitung (12, 13) und der Lastaufnahme (1) sind angegeben. An attachable to a hoist rope load-receiving device (1) has for receiving a stop means by a headband (11) on a support (2) closable mounting recess (30). The retaining clip (11) can be blocked by a bolt (22) which is actuated by a spring-loaded piston (4) guided in a hydraulic cylinder when lifting a load in the locking direction. The two cylinder chambers are connected by a gap between the cylinder and the piston (4) released by a lip seal (6) of the piston (4) acting only in one direction. For the return of the piston (4) to release the retaining clip (11) by the latch (22) for settling the load, a connection of the cylinder chambers via a flow-controllable line (12, 13). Advantageous embodiments of the flow control of the line (12, 13) and the load bearing (1) are given.
