QTZ250-7025 12 Ton Flat Top Tower Crane

QTZ250-7025 12 Ton Flat Top Tower Crane

The QTZ250-7025 Flat Top Tower Crane is a heavy-duty tower crane developed by DAHAN for large-scale construction projects requiring high lifting capacity, wide working coverage, 

and exceptional height performance. The model features a flat top structure, 70-meter jib length, and a rated lifting moment of 250t·m, 

making it suitable for modern high-rise buildings, industrial facilities, infrastructure projects, and large commercial developments.

With a maximum lifting capacity of 12 tons (available configurations up to 16 tons), the QTZ250-7025 provides reliable lifting performance for heavy construction materials, 

steel structures, precast components, and mechanical equipment. Its 70m working radius allows contractors to cover larger construction areas with fewer crane repositioning requirements.

The flat top design simplifies transportation, installation, and dismantling while improving efficiency when multiple cranes operate on the same construction site. 

Compared with traditional tower crane structures, the topless configuration reduces interference between cranes and provides greater flexibility for complex urban construction environments.

The crane integrates advanced PLC control technology with high-performance motor and gearbox systems to achieve smooth hoisting, accurate positioning, and stable operation. 

The intelligent control system helps improve working efficiency while reducing mechanical impact and energy consumption.

Designed with a robust steel structure and modular mast system, the QTZ250-7025 can achieve a maximum lifting height of up to 333m according to project configuration, 

making it an excellent choice for super high-rise buildings and large-scale engineering projects.
