Abstract: 본발명의 안전디스크 브레이크로, 간단한 구조로 법규에서 요구하는 모든것인 구조적인 작동력을 충족할수 있다. 가장 중요한 안전성의 요구에 대한 충족은 서로 기계적으로 완전히 독립적으로 작동하는 두개의 부분적인 장치가 통상의 스프링 중심체(2,3)에서 지지되며 기계부(1)와 견고하게 연결된 그 회전체에 존재하는 각각 분리된 압축스프링(9)(10)을 가지며, 두개의 동일한 브레이크 레버(4)의 형태로 구비되어있다. 안정성을 충족하기위한 또다른 특징으로 두개의 부분적인 장치 모두가 상호 기계적으로 서로 관통하거나 겹치지 않는것이다. 
     브레이크의 분리가능은 한개의 브레이크레버(4)에 단단히 고정된 포트 마그네트(5) 및 다른 브레이크 레버(4)에 마찬가지로 단단히 고정된 아마츄어판(6)에 의해 전자기적으로 발생한다. 브레이크레버(4)에 포트 마그네트(5)와 아마츄어판(6)의 체결은 아마츄어판(6)이 포트 마그네트(5)에 의해 항상 정확하고 평행하게 끌어당겨질수 있도록 조정될 수 있으며 이와같이하여 어떠한 충격소음도 발생하지 않는다.
