{"id":37,"count":22,"description":"A <strong>compare verticale<\/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>mantenimento statico<\/strong>.    The key characteristics of a hoist brake are:  <ol>   \t<li><strong>Design di sicurezza fail-safe:<\/strong>\u00a0I freni di sollevamento sono universalmente\u00a0<strong>a molla applicata e a energia rilasciata<\/strong>. Questa \u00e8 l'essenza della loro natura di sicurezza. Molle meccaniche potenti forniscono la forza per bloccare il freno di default. \u00c8 necessario energia elettrica o idraulica per attivare\u00a0<em>rilascio<\/em>\u00a0il freno.<\/li>   \t<li><strong>Principio Operativo:<\/strong>  <ul>   \t<li>Quando il motore del paranco \u00e8 comandato a sollevare o abbassare, la bobina del freno viene energizzata nello stesso istante, rilasciando il freno e permettendo al motore di girare.<\/li>   \t<li>Nel momento in cui il motore viene disattivato (sia per comando che per mancanza di energia), la forza di rilascio sul freno scompare. Le molle si attivano istantaneamente e automaticamente, ingaggiando il freno con tutta la forza, mantenendo saldamente il carico sospeso in posizione statica.<\/li>  <\/ul>  <\/li>   \t<li><strong>Posizione:<\/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\/it\/tag\/hoist\/","name":"compare verticale","slug":"hoist","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/tags\/37","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/posts?tags=37"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
