Hengsheng Flat-Top Tower Crane

The Hengsheng Flat-Top Tower Crane, also known as the topless tower crane, is a revolutionary piece of engineering excellence that eliminates the traditional tower head (tower cap). Originating from the innovative minds in Europe, this advanced crane design presents a multitude of benefits over conventional tower cap cranes.

This characteristic makes it indispensable for construction projects necessitating the simultaneous use of several cranes. Furthermore, the flat-top design enhances safety and efficiency when operating near high voltage lines, offering a superior choice for complex construction environments.
