A hoist (80) for construction sites, for carrying loads suspended from a crane. The hoist (80) is C-shaped, suspended at its top arm by a cable (90) of a crane. The bottom arm carries a hook (92), 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.
