Recently, at a major polysilicon industry upgrade project, an XCMG QUY450 (450t) crawler crane and an XCMG XGC12000 (800t) crawler crane worked together to successfully complete the first hoisting of a large-scale distillation tower.

The tower, weighing 352 tons, standing 64 meters tall and 6.7 meters in diameter, is a core component of chemical processing and required millimeter-level lifting accuracy. The two cranes overcame key challenges such as boom interference, force balance, and synchronized control, while carrying out simultaneous lifting and precise positioning in a confined space.

On site, the QUY450 lifted the 225t lower section while the XGC12000 hoisted the 127t upper section. Both cranes worked in perfect coordination, completing the task safely and smoothly. This highlighted XCMG’s strength in multi-crane collaboration under complex conditions, once again proving its capability in hoisting ultra-large components in restricted environments.

From distillation towers to bridge girders, steel modules, and wind turbine towers, XCMG provides integrated lifting solutions across the full project process. Moving forward, XCMG will continue to drive innovation, enhance collaborative control, and expand intelligent lifting technology, delivering safer, more efficient, and reliable solutions for major domestic and international construction projects.
