Abstract

The purpose of the present invention is a brake device, especially for crowd control and road barriers. The device comprises a frame 2 with at least one lengthwise passage 5, 5', 5", intended to lodge at least one segment of cable F, F', F", integrated with a safety barrier, at least two pairs of fixed rollers 13, with axles alongside each other, placed toward the end of the lengthwise passage to movably guide the cable, at least three movable rollers 15 with parallel axles and in intermediate positions relative to the fixed ones 13, guiding means 21, 21', 21", integrated with the frame 2 to permit the controlled sliding of the axles of the movable rollers 15 along a lengthwise direction, means of locking 20 acting on the movable rollers to oppose their sliding along the guiding means. The segment of cable which extends between the pairs of fixed rollers 13 is wound in zigzag manner on the movable rollers 15, so that by exerting a traction on the cable the movable rollers are forced to move in translation against the action of the locking means 20, dissipating energy. The brake device allows a substantial dissipation of energy with minimum sliding and limited wear. <IMAGE>
