Abstract
A centrifugal brake is disclosed which comprises centrifugal shoes which cooperate with supplemental weights. Each supplemental weight has a ring-type basic shape and, by means of a ring part, extends along the centrifugal shoe to be affected. In addition, the supplemental weight interacts with the centrifugal shoe by way of a transmission element and a support part.
