Abstract: PROBLEM TO BE SOLVED: To provide a constraint brake device having a lift-cage trigger device having different braking effects in upward and downward moving directions. SOLUTION: A rocking device is tilted by a tension member 4 up to supports 13.1, 13.2 beyond the dead center of the rocking device according to an upward or downward moving direction. The tilting causes one or the other pan type yield joint 6.1 or 6.2 to be pressed against a biased adjustable compression spring 10.1 or 10.2, and movable brake shoes 14, 15 and fixed brake shoes 30, 31 are pressed against a guide rail 7 accordingly. The compression springs 10.1, 10.2 aligned within a spring block 22 can be individually variably biased from respective adjustment screws 11.1, 11.2.

Abstract: In this arresting brake device with triggering equipment for lift cages with dif ferent braking effect in upward and downward direction of travel, a tiltable rocker (1), as a b arrier element, is provided with an articulated (2.1/2) two-point bearing in yielding j oint pans (6.1/2). The rocker (1) is operatively connected with a movable brake shoe (14/1 5) and is, on actuation by triggering equipment (21), tilted by entraining members (4) up t o an abutment (13.1/2) beyond or ahead of its dead centre according to direction of t ravel in upward or downward direction. By the tilting movement, one or the other yielding joint pan (6.1/2) is pushed against a biased adjustable compression spring (10.1/2) and th e movable brake shoe (14, 15) and a fixed brake shoe (30, 31) are accordingly urge d against the guide rail (7). The compression springs (10.1/2), which are arranged in a spring block (22), can each be biased separately in variable manner by a respect ive setting screw (11.1/2).
