Lifting of 900-ton butene-1 distillation column for the Zhongsha Gulei project
Thread Content
On March 21, good news came from the Zhongsha Gulei project site: the butene-1 distillation tower was successfully hoisted into place. After being equipped with various attachments, the weight of this equipment is nearly 900 tons; for lifting, a 4000-ton crawler crane is used as the main lifting device, while a 500-ton crawler crane is used to assist in guiding the equipment.
The 4,000-ton crawler crane, the first set of oversized equipment to arrive at the Zhongsha Gulei project, arrived at the port in November 2024. The project’s technical and construction team worked efficiently to carry out its assembly and testing; through CAD simulations and on-site measurements, an innovative approach involving the use of axis-driven vehicles and crawler cranes was employed for the assembly process. On December 20, 2024, the first ethylene distillation column, weighing over 900 tons, was successfully lifted into place with precision, marking the beginning of the lifting process for the core columns. On March 21, 2025, it completed the final lift for the Zhongsha Gulei project. During the 120 days of combat on the Gulei Peninsula, this \"major engineering marvel\" successfully carried out the lifting of a total of 7 tower structures, each weighing nearly 10,000 tons.
