Hengsheng Flat-Top Tower Crane

The Hengsheng Flat-Top Tower Crane, also known as the topless tower crane, is a marvel of modern engineering that eliminates the traditional tower head (tower cap). Originating from Europe, this cutting-edge crane design provides a multitude of advantages over conventional tower cap cranes, making it a superior choice for contemporary construction needs.

One of the standout features of the flat-top tower crane is its exceptional ability to minimize the height difference between multiple cranes when operating in tandem. This makes it an ideal solution for complex construction projects requiring the simultaneous operation of several cranes. Furthermore, the flat-top tower crane is perfectly suited for work near high voltage lines, ensuring safer and more efficient operations in these challenging environments.
