Hengsheng Flat-Top Tower Crane

The Hengsheng Flat-Top Tower Crane, also known as the topless tower crane, redefines construction excellence with its innovative design. Originating from European engineering brilliance, this crane stands out by eliminating the traditional tower head (tower cap), offering a multitude of advantages over conventional cranes.

One of the standout features of the flat-top tower crane is its remarkable ability to significantly minimize the height disparity between multiple cranes operating concurrently. This makes it exceptionally suitable for large-scale construction projects requiring a fleet of cranes. Moreover, its design is optimized for working safely under high voltage lines, enhancing both operational safety and efficiency in demanding environments.
