The winch drum for lifting troncu00d3nico loads, with a height of approximation of hook lifting operation reduced.This invenu00c7u00c3o refers to a winch for lifting of cargo suspended by a hook (3) and a steel cable (5) which is wound on a drum troncu00d3nico (1) so as to reduce the vertical extensions of the winch when the hook (3) is in the upright position at the maximum permitted area The vertical lifting operation available.And in simultu00c2neo decrease the effort applied to the actuation of the lifting motor (4) as the loading amounts.
