DH620-8530 QTZ500 Series 25 Ton Flat Top Tower Crane

DH620-8530 QTZ500 Series 25 Ton Flat Top Tower Crane

The DH620-8530 QTZ500 Series Flat Top Tower Crane is a next-generation heavy-duty lifting solution developed by DAHAN for high-rise buildings, industrial construction, infrastructure development, bridge engineering, and large-scale energy projects.

Featuring a maximum lifting capacity of 25 tons and an 85-meter jib length, the crane provides excellent working coverage while maintaining high lifting efficiency. Its rated lifting moment of 500t·m enables stable handling of heavy structural components, steel modules, precast concrete elements, and oversized construction materials.

The flat top structure eliminates the traditional tower head, making transportation, installation, and dismantling more efficient while reducing interference during multi-crane operations. This design is especially suitable for large construction sites where multiple cranes operate simultaneously.

The crane adopts advanced variable frequency drive technology for hoisting, trolleying, and slewing mechanisms. Smooth acceleration and deceleration improve positioning accuracy, reduce mechanical wear, lower energy consumption, and extend equipment service life.

Manufactured with high-strength structural steel and precision welding technology, the DH620-8530 offers excellent rigidity, durability, and wind resistance. Every crane undergoes strict quality inspection before delivery to ensure reliable performance under demanding working conditions.

With a maximum lifting height of up to 350 meters, the DH620-8530 is an ideal lifting solution for super high-rise buildings and large infrastructure projects requiring outstanding height performance and lifting reliability.
