{"id":37,"count":22,"description":"A <strong>Levantado<\/strong> is a mechanical device used for lifting and lowering a load, typically with a drum or lift-wheel around which a rope or chain is wrapped. In the context of industrial brakes, the hoist application is defined by one paramount, non-negotiable requirement: the <strong>absolute prevention of a dropped load<\/strong>.    Consequently, the brake on a hoist is the primary safety device. It is not principally a dynamic or service brake for slowing the load (this is largely managed by the motor and drive); its most critical function is <strong>sujeci\u00f3n est\u00e1tica<\/strong>.    The key characteristics of a hoist brake are:  <ol>   \t<li><strong>Dise\u00f1o a prueba de fallos:<\/strong>\u00a0Los frenos de cabrestante son universalmente\u00a0<strong>aplicado por resorte y liberado por energ\u00eda<\/strong>. Esta es la esencia de su naturaleza a prueba de fallos. Resortes mec\u00e1nicos potentes proporcionan la fuerza para sujetar el freno por defecto. Se requiere energ\u00eda el\u00e9ctrica o hidr\u00e1ulica para activar\u00a0<em>liberar<\/em>\u00a0el freno.<\/li>   \t<li><strong>Principio operativo:<\/strong>  <ul>   \t<li>Cuando se ordena al motor del polipasto subir o bajar, la bobina del freno se energiza al mismo instante, liberando el freno y permitiendo que el motor gire.<\/li>   \t<li>En cuanto el motor se desenergiza (ya sea por comando o por una falla de alimentaci\u00f3n), la fuerza de liberaci\u00f3n en el freno desaparece. Los muelles engranan instant\u00e1neamente y de forma autom\u00e1tica el freno con toda la fuerza, manteniendo de forma segura la carga suspendida en una posici\u00f3n est\u00e1tica.<\/li>  <\/ul>  <\/li>   \t<li><strong>Ubicaci\u00f3n:<\/strong>\u00a0The brake is typically mounted directly to the non-drive end of the hoist motor, on the high-speed side of the drivetrain before the gearbox. This placement takes advantage of the gearbox's mechanical advantage, meaning a smaller, faster-acting brake can effectively hold the full load torque seen at the drum.<\/li>  <\/ol>  Whether it's a small workshop chain hoist using an integrated DC electromagnetic brake or a massive steel mill crane with a large electro-hydraulic drum brake, the fundamental principle remains the same: the brake's primary and most vital role is to fail into the \"on\" position, guaranteeing that the load will not fall.","link":"https:\/\/www.takebrakes.com\/es\/tag\/hoist\/","name":"Levantado","slug":"hoist","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/es\/wp-json\/wp\/v2\/tags\/37","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.takebrakes.com\/es\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.takebrakes.com\/es\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.takebrakes.com\/es\/wp-json\/wp\/v2\/posts?tags=37"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
