Quando si seleziona una frizione di sicurezza per il paranco, verificare non solo la coppia nominale, ma anche il ciclo di lavoro, la capacit\u00e0 termica per arresti dinamici di emergenza e la capacit\u00e0 di mantenere il carico per periodi prolungati senza slittamento.<\/p>","protected":false},"excerpt":{"rendered":"<p>A hoist is a gravity-loaded system: if power is lost, the load will try to move in the unsafe direction (down).
