DAHAN QTZ315-7527 12-18 Ton Flat Top Tower Crane

QTZ315-7527 12-18 Ton Flat Top Tower Crane

The DAHAN QTZ315-7527 Flat Top Tower Crane is a heavy-duty topless tower crane developed for modern construction projects requiring high lifting capacity, large working radius, and reliable operation.

Designed with a maximum lifting capacity range of 12-18 tons, the QTZ315-7527 provides excellent performance for handling heavy construction materials, steel structures, precast concrete components, mechanical equipment, and other large loads.

With a maximum jib length of 75 meters, the crane offers wide working coverage and reduces the need for frequent relocation during construction. Its powerful lifting capability and stable structure make it suitable for high-rise buildings, commercial complexes, industrial plants, and large infrastructure projects.

The flat top design eliminates the traditional tower head structure, making transportation, assembly, and dismantling more convenient. This topless configuration also improves efficiency when multiple cranes operate together on the same construction site by reducing interference between cranes.

The QTZ315-7527 adopts a reliable motor and gearbox transmission system, providing smooth hoisting, stable trolley movement, and precise slewing operation. The advanced control system improves operational safety while reducing mechanical impact and energy consumption.

Safety is a key feature of this model. The crane is equipped with multiple protection systems including overload protection, moment limitation, height limitation, and emergency braking systems to ensure safe operation throughout the construction process.

With a maximum lifting height of 240 meters, the QTZ315-7527 is an ideal choice for high-rise construction and complex engineering projects requiring strong lifting performance and long-term reliability.
