ABSTRACT:
A pendulum brake for cushioning pendulum movements, especially for grab buckets of hydraulically operable earth dredges in which the pendulum brake is arranged at the free end of the shank. A grab bucket holder and a drum are by means of fitting keys non-rotatably connected to a bolt which serves as shaft and is rotatably journaled in bearings at the free end of the shank. The drum cooperates with two clamps provided with brake linings while the clamps embrace the drum and by means of a clamping screw and dish springs exert a pressure upon the drum.
