Abstract

<B>MECANISMO DE SEGURANçA<D>. Expõe-se um mecanismo de segurança (1), que compreende uma armação provida de uma superfície de frenagem que, quando o mecanismo de segurança está sendo frenado, é pressionado contra uma primeira superfície de orientação de um trilho-guia. Montado na armação está previsto um rolete (3), o qual movimenta-se ao longo de uma trilha prevista no mecanismo de segurança. A trilha compreende pelo menos um primeiro gradiente e um segundo gradiente, sendo o primeiro gradiente dotado de um ângulo de passo maior do que o segundo gradiente. O rolete é pressionado contra a segunda superfície de orientação do trilho-guia quando o mecanismo de segurança está sendo frenado. O rolete (3) é dotado de um agarramento mais forte na trilha do primeiro gradiente do que no segundo gradiente.
