The Dahan QTZ 250 (available in DH7027 for 16 t max load, and DH7032 for 12 t) is a high-performance topless/top-kit tower crane featuring a 70 m jib, delivering 2.7 t (DH7027) or 3.2 t (DH7032) at full reach. Designed for urban and industrial mega-projects, it offers a 52.5 m free-standing height, extendable to ~220 m via tie‑ins. Constructed with robot-welded Q345B steel and premium parts (Schneider, Rothe Erde, Jiangte motors), it emphasizes structural safety and low-maintenance performance. Equipped with variable-frequency hoist, trolley, and slewing drives—and full safety systems (torque, LMI, rope-break protection)—it ensures smooth, secure, and efficient lifting. Modular topless/top-kit design enables rapid erection and suitability for multi-crane zones. CE/ISO certified and supported by Dahan’s global service network, the QTZ 250 offers a powerful, reliable, and space-efficient lifting solution for demanding construction environments.
