{"id":37,"count":22,"description":"A <strong>\u0631\u0641\u0639<\/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>\u062b\u0627\u0628\u062a \u0623\u062b\u0646\u0627\u0621 \u0627\u0644\u062d\u0645\u0644 (static holding)<\/strong>.
