【HaiChuan Chemical Engineering Updates】The first lift of the 4,000-ton crawler crane for the Shandong Yulong Petrochemical project”
Thread Content
At 6:30 on April 8, 2023, upon the command of the overall lifting supervisor, Tower A of the propylene unit in Project 6 of Shandong Yulong Petrochemical’s refining facility was slowly lifted by a 4,000-ton crawler crane. After 9.5 hours, it was successfully installed in place at 16:00. The propylene column is divided into Tower A and Tower B; it has a diameter of 7 meters, a height of 85 meters, and a weight of 750 tons. For this lifting operation, a crawler crane with the highest single-unit lifting capacity in China, at 4000 tons, was used. The tracks of this crane alone are over 3 meters high; its two crawler bases together cover an area larger than that of a basketball court, and its weight is 6000 tons.
