Four pulleys were attached to the top four, and an object was attached under the bottom pulley. A cord that could be pulled in both directions of the back pulley was wound around the water-wheel so that the object could be lifted through the cord connected to the pulley as it turned the wheel. A complete picture of a fully assembled figure and a disassembled picture of each part is displayed on the gauge of Hwaseong Fortress Station. The book lists the type and quantity of equipment made for the construction of Suwon Fortress (Hwasong), and one crane was used, which was made by the royal family and sent down to the construction site.
