Product Description
 

Hengsheng Flat-Top Tower Crane

The Hengsheng Flat-Top Tower Crane, also known as the topless tower crane, is a revolutionary crane design hailing from Europe. Unlike traditional tower cranes, this advanced model boasts a tower crane without a tower head (tower cap), offering a myriad of benefits over conventional tower cap cranes.

A standout feature of the flat-top tower crane is its remarkable ability to significantly reduce the height disparity between multiple cranes when working in tandem. This attribute makes it the optimal choice for complex construction projects requiring several cranes. Moreover, its design ensures it operates safely and efficiently under high voltage lines, marking it as a superior choice for such challenging environments.

With a legacy of over 20 years in crafting top-tier construction elevators, HENGSHENG CONSTRUCTION EQUIPMENT is synonymous with trust and excellence. The esteemed Hengsheng Flat-Top Tower Crane proudly carries the ISO9001 international quality system certification, a testament to its unmatched reliability and performance.
