Un frein de s\u00e9curit\u00e9 (\u00e9galement appel\u00e9 frein sans alimentation ou frein \u00e0 ressort) est con\u00e7u pour s\u2019engager automatiquement lorsque l\u2019alimentation est coup\u00e9e. Dans son \u00e9tat naturel, de fortes ressorts appliquent une force de serrage sur le disque ou le tambour. L\u2019\u00e9nergie \u2014 hydraulique, pneumatique, \u00e9lectromagn\u00e9tique ou \u00e9lectro-hydraulique \u2014 n\u2019est utilis\u00e9e que pour lib\u00e9rer le frein en vue du mouvement. En cas de panne d\u2019alimentation due \u00e0 un arr\u00eat d\u2019urgence, une d\u00e9faillance de c\u00e2ble ou une coupure g\u00e9n\u00e9rale, le frein s\u2019engage imm\u00e9diatement pour s\u00e9curiser la charge ou maintenir la machine.<\/p>
Utilisez un frein de s\u00e9curit\u00e9 chaque fois qu\u2019un mouvement incontr\u00f4l\u00e9 pourrait causer des blessures, des dommages \u00e0 l\u2019\u00e9quipement ou une non-conformit\u00e9 r\u00e9glementaire. Les applications typiques incluent les m\u00e9canismes de levage de grues et de palans, le freinage de lacet et de rotor des turbines \u00e9oliennes, les treuils miniers, les convoyeurs en descente (pr\u00e9vention du retour en arri\u00e8re) et les syst\u00e8mes d\u2019ascenseur.<\/p>
Un frein de s\u00e9curit\u00e9 ne signifie pas automatiquement \u00ab capable d\u2019un arr\u00eat d\u2019urgence \u00bb pour le freinage dynamique fr\u00e9quent \u2014 v\u00e9rifiez toujours le cycle de service, la capacit\u00e9 d\u2019\u00e9nergie et les limites thermiques. Lorsqu\u2019il est correctement s\u00e9lectionn\u00e9, le freinage de s\u00e9curit\u00e9 est une philosophie de s\u00e9curit\u00e9 fondamentale, et non une caract\u00e9ristique optionnelle.<\/p>","protected":false},"excerpt":{"rendered":"
A fail-safe brake (also called a power-off brake or spring-applied brake) is designed to engage automatically when power is removed. In its natural state, strong springs apply clamping force to the disc or drum. Power\u2014hydraulic, pneumatic, electromagnetic, or electro-hydraulic\u2014is only used to release the brake for motion.
