[Haichuan Eye-opener] Using hydraulic jacking method to hoist a 128-meter 2957-ton product separation tower

Special lifting system different from hydraulic lifting

State before promotion @ wise man 明 @书通

Start jacking up, look at the flag, this should be the hydraulic jacking system of Sinopec 10th Construction

Eye-opening:victory:

How big should this sliding-tail crane be? ? ? ---------------------------------------------

On February 3, after 7 hours and 17 minutes, the product separation tower of Dongguan Juzhengyuan Phase II project was successfully hoisted into place in one go. The hoisting uses a 3,600-ton hydraulic jacking system, with a hoisting weight of 2,957 tons.

The product separation tower is the core equipment of Juzhengyuan Technology Co., Ltd.'s 1.2 million tons/year propane dehydrogenation to high-performance polypropylene project (Phase II). It is 128 meters high and the tower body diameter is 9.2 meters. After installing tower internals, attached tower structural pipes and cold insulation materials on the ground, plus U-shaped beams, rigging, etc. for hoisting, the total hoisting weight of the equipment reaches 2,957 tons, making it a "Big Mac" among tower equipment. In order to ensure the success of the equipment hoisting, the leaders of Shijian Company attached great importance to it, held many special meetings to study the deployment, and sent experts to provide technical guidance and business training on the hydraulic jacking system to solve practical problems encountered during the operation of the system. In accordance with the leadership's requirements, the Heavy Machinery Branch of the main battle unit organized capable professional construction personnel to enter the site, continuously optimized the construction plan, and successively completed a series of complex tasks such as maintenance, grouping and debugging of two sets of 90.80-meter-high hydraulic jacking towers, improving work efficiency by 30% and fully preparing for the hoisting of large towers. During the preparation process for equipment hoisting, the Juzhengyuan Engineering Project Department carried out scientific organization, overall coordination and careful deployment according to the overall construction plan of the project. Especially after the product separation tower was fabricated and formed on site, in order to ensure the realization of the hoisting node goal, the project department's civil engineering, installation, electrical instrumentation, anti-corrosion and cold insulation and other majors worked closely together and invested manpower and material resources in day and night construction. It took 28 days to complete the equipment "dressing and hating", "tower lighting" and other tasks, creating conditions for the hoisting of the large tower. For this hoisting, Shijian Company used the domestically advanced 3,600-ton hydraulic jacking system main crane and operated it using a computer control system to accurately control the entire hoisting process. This system has the characteristics of large lifting capacity, high safety, and strong maneuverability in transition, which greatly improves work efficiency, saves engineering costs, reduces operating risks, and ensures construction safety.
