Hengsheng Flat-Top Tower Crane

The Hengsheng Flat-Top Tower Crane, also known as the topless tower crane, is a pioneering innovation that eliminates the traditional tower head (tower cap). Originating from Europe, this state-of-the-art crane offers a myriad of advantages over conventional tower cap cranes.
