Abstract

The grab for raising or lowering loads, driven by a rotating roller or winding mechanism, e.g. for a hoist, has a control disc (14) rotating with the drive roller (12) etc. The control disc has a number of peripheral teeth (17), with a lever arm (26), carrying a roller (28) at its free end positioned adjacent the control disc (14) so that the roller (28) fits into the notch between each two peripheral teeth (17) of the control disc (14), this arm (28) being flung outwards away from the control disc (14) in dependence on the speed of rotation. The lever arm (26) is connected via a lever (20) with a ratchet arm (27) for engaging the teeth (17) of the control wheel (14). The latter teeth (17) pref. have a sawtooth configuration with the slanting edge (19) of each tooth (17) being curved outwards.
