The helibucket is for loading, transporting and discharging water and products on fires and hangs from the loading hook of a helicopter. It is formed by a head which is linked to the helicopter, fastening cables, a cover with the foam tank, the floater and the mechanisms box, the base, which supports the weight and houses the discharge valve, the autonomous filling valves and the pump and a flexible canvas which joins the cover with the base. A motor with three reels for winding the cables controls the loading, unloading and folding. Hermetic closing is achieved since the surface of the bottom of the bucket is greater than that of the valve, and on taking weight, the helibucket moves downwards to the elastic limit of its cables, forcing the body of the valve against the valve gates thereby closing it. The helibucket is useful for extinguishing forest fires, increases to a great extent efficiency in firefighting as it transports 100% of the water it loads and enables the pilot to control how and how much water it discharges.
