Abstract

"FREIO DE SEGURANçA DE ELEVADOR". A presente invenção provê um coxim de freio de segurança de elevador e uma estrutura de coxim de freio de segurança de elevador para uso em elevadores de alta velocidade e altas cargas. O coxim de freio é, de preferência, fabricado de um material em carbono metálico e pode apresentar um acabamento polido. O coxim provê um coeficiente de atrito consistente que não se deteriora com o uso. Também se divulga um calço de freio de segurança de elevador, que é apropriado para uso com o coxim de freio de segurança de elevador e com a estrutura de coxim de freio de segurança de elevador.
