A safety gear system for an elevator has a main static mass (13), an auxiliary static mass (3) and a dynamically changing mass (2), wherein the dynamically changing mass (2) changes in accordance with the travel of the main static mass (13). The safety gear system comprises at least one first safety gear (8) which is configured to brake the auxiliary static mass (3) by a constant braking force, and at least one second safety gear (9) which is configured to brake the main static mass (13) and the dynamically changing mass (2) by an adjustable brake force which is adjustable in accordance with the change of the dynamically changing mass (2).
