On March 3, 2023,  SPCECC used a 4,000-ton crawler crane to complete the hoisting of the second high-pressure distillation tower of the CTA1 unit in Hainan Yisheng Petrochemical Project.

After the hoisting of the first high-pressure rectification tower was completed on February 20, 2023, the project department immediately started to prepare for the hoisting of the second high-pressure rectification tower. In order to successfully complete the hoisting task, the hoisting technical team seized the time and progress, arranged for experienced hoists to make multiple measurements, made a detailed hoisting plan, and carefully prepared the hoisting plan and the handling plan for the crane walking site. At 12:00 noon on March 3, 2023, the second high-pressure distillation tower with a net weight of 1278 tons, a diameter of 8.5 meters, and a height of 80.5 meters was successfully completed. A good foundation has been laid for the hoisting of project equipment.
