On site, the upper and lower tower sections weighing 127t and 225t were smoothly lifted. Under millimeter level precision control, the hook achieves precise operation. With the precise docking of the final tower at the predetermined height, the high difficulty distillation tower lifting task has been successfully completed. From the precise hoisting of heavy towers to the project guarantee of the "the Belt and Road" project, XCMG lifting machinery, with its excellent performance and reliable quality, serves the global infrastructure construction and writes new possibilities in the global major project construction.
