Abstract
In a block brake with brake block regulator, which maintains the brake block shoe (6) in a predetermined rotational position about its rotational axis (5) through friction blocks (20) and friction surfaces (14), the friction surfaces (14) are in the form of wedge surfaces, such that, upon rotation of the brake block shoe (6) under the influence of gravity, the friction blocks (20) must be forced back through the friction surfaces (14) against their spring loading (18). This enables compensation of the turning moment brought to bear on the brake block shoe (6) by the gravitational force.
