Twiflex VCS Series disc brake calipers provide a high degree of strength and reliability on both geared and gearless motor elevator drives. Twiflex VKSD spring-applied, hydraulically-released caliper brakes are also used on high-performance elevator drives installed in skyscrapers. Twiflex MXSE spring-applied, electromagnetically-released brakes act on an integral flange to the traction sheaves on freight and passenger elevators.
