The ZCC3200NP, equipped with a heavy-duty fixed auxiliary arm, is used to lift the 1,850-ton Shenghong Refining & Chemical Plant’s No. 1 propylene tower

【1,850 tons! Zoomlion’s 3,200-ton crawler crane sets another lifting record】Recently, on the coast of Xuwei New Area in Lianyungang, Zoomlion’s ZCC3200NP crawler crane once again broke its own lifting record by successfully lifting the 1,850-ton heavy 1st propylene tower, thereby contributing to significant progress in the Shenghong Petrochemical Integration Project, a world-class petrochemical industry complex. It is understood that the Shenghong refining and chemical integration project has a total investment of around 67.7 billion yuan, with an annual capacity to process 16 million tons of crude oil. It is expected to be completed and put into operation in 2021, at which time it will be able to generate an annual output value of over 90 billion yuan and profits and taxes of over 20 billion yuan. Once put into operation, this project will play a significant role in promoting the transformation and upgrading of the **petrochemical industry, optimizing the supply-side structure, and achieving high-quality development of the industry. ?“Tower No. 1 for propylene is the most critical aspect of the lifting construction for the Shenghong refining and chemical integration project. ”It is reported that there are two major challenges in the lifting construction of Column 1 propylene tower: First, the foundation treatment at the bottom of the tower is complex ； Secondly, the lifting is extremely difficult; with a total weight of 1,850 tons, a diameter of 8 meters, and a height of 105 meters, it is one of the heaviest, largest in volume, and tallest propylene towers in China at present. Lifting it requires the use of super-large tonnage cranes in combination with cranes capable of handling thousands of tons. ?After repeated verification by the project constructor, China Nuclear Machinery, it was decided to equip the ZCC3200NP with a heavy-duty fixed auxiliary arm in order to carry out this important lifting task. Upon receiving the request from China Nuclear Machinery for equipment upgrades, Zoomlion responded promptly by developing a specific configuration for the ZCC3200NP: a \"102-meter main arm + 24-meter heavy-duty fixed auxiliary arm\" setup. This configuration enables a maximum lifting capacity of 2,300 tons, which is ideal for lifting petrochemical equipment with small movements but large loads; it significantly enhances the lifting capabilities of this 3,200-ton model for petrochemical applications. After the operating conditions for the main crane, the ZCC3200NP heavy-duty fixed auxiliary arm, were determined, the contractor selected the Zoomlion ZCC12500 crawler crane as the auxiliary crane. After 3 hours and 32 minutes of careful maneuvering, the lifting task was finally completed successfully, setting a \"dual record\" as the highest and heaviest tower equipment lifted at the Shenghong refining and chemical integration construction site. The ZCC3200NP crawler crane has a maximum lifting capacity of 3200 tons; it is the first crawler crane of 3000-ton class in China. Its production marked an end to foreign countries’ monopoly on cranes of this tonnage class. After the hoisting of Column 1 for propylene is completed, ZCC12500 and ZCC3200NP will continue to be in service at the Shenghong integrated refining and chemical project.

A 3,200-ton crawler crane is really impressive too; great!

The key point of this report is that a special modification was made to the crane arm
