Product Description

Product Description

Hengsheng Flat-Top Tower Crane

The Hengsheng Flat-Top Tower Crane, also known as the topless tower crane, is a tower crane without a tower head (tower cap). Originating in Europe, this innovative crane design offers numerous advantages over traditional tower cranes.

One of the key benefits of the flat-top tower crane is its ability to greatly reduce the height difference between two tower cranes when operating in a group. This makes it ideal for construction projects where multiple cranes are required. Additionally, the flat-top design allows for easier operation and maintenance.

Another advantage of the Hengsheng flat-top tower crane is its suitability for working under high voltage lines. Unlike tower cap tower cranes, the flat-top design eliminates the need for a tower head, making it safer and more efficient in such environments.

With over 20 years of experience in the production and manufacturing of construction elevators, HENGSHENG CONSTRUCTION EQUIPMENT is a trusted name in the industry. The Hengsheng flat-top tower crane has passed the ISO9001 international quality system certification, ensuring its reliability and performance.

Choose the Hengsheng construction elevator and experience the best construction machine you've always wanted. With independent R&D, design, and generation departments, Hengsheng is committed to providing top-quality products that meet the needs of construction professionals.
