Abstract
A load lifting winch suspending a load from a hook (3) and a cable (5) which is wound onto a frustoconical drum (1) in order to reduce the winch vertical dimension when the hook (3) is in the fully upright position allowed by available vertical space elevation, and simultaneously decrease the forces applied to the lifting drive motor (4) as the load rises.
Claims3
A frustoconical drum winch for lifting loads with hook reduced approximation lifting height, characterized by using a hook that lifts by winding a cable in a frustoconical drum up to a height dimension higher than the lower the point of the median diameter of the frustoconical drum.
