Hoist for construction material

Image Number 7 for United States Patent #7229109.

A hoist for construction sites, for carrying loads suspended from a crane. The hoist is C shaped, suspended at its top arm by a cable of a crane. The bottom arm carries a hook, typically vertically movable, for lifting and moving loads about in the construction site. Owing to its lateral opening, the hoist can deliver loads into the interior space of floors, using minimal crew and relying mainly on the crane for maneuverability.
