Camac-Smart is a small rack&pinion materials hoist, single-phase with capacity 250Kg, designed to be installed either inside or outside any scaffold. Its light aluminum mast sections allow that just one only worker may do its complete montage. This materials hoist is designed to enable the scaffold assembly and after that to lift materials on it, during the construction or refurbishing works. The incorporation of the wireless hand control, makes it more flexible and increases the efficiency in the working site.
