Hengsheng Flat-Top Tower Crane

The Hengsheng Flat-Top Tower Crane, also referred to as the topless tower crane, is a revolutionary crane design without a traditional tower head (tower cap). This pioneering concept, which originated in Europe, provides a multitude of advantages over conventional tower cap cranes.

This feature is particularly advantageous for complex construction projects requiring several cranes. Additionally, its unique design makes it exceptionally well-suited for tasks under high voltage lines, offering enhanced safety and operational efficiency.

With a rich legacy of over 20 years in the production and manufacturing of construction elevators, HENGSHENG CONSTRUCTION EQUIPMENT has established itself as a leading authority in the industry.
