The invention relates to a safety braking device for elevators, able to operate both during ascent and descent, which comprises two wedges (12 and 13), one for braking a cabin in descent and another for braking the cabin in ascent, each of which wedges is associated to a guide having an inclined plane and can assume, independently of the other wedge, an active braking position, in which it is compressed contactingly between a guide having an inclined plane and a fixed vertical element (4). The wedges are arranged side-by-side and are actuated independently by two levers (8 and 9) commanded independently by a bracket (5), to which they are connected relatively moveably in slots (6 and 7). The bracket (5) is fixed to a cable (3) which commands brake activation. <IMAGE> |
