【Ten Years of Rapid Development in Chemical Engineering Equipment】From 1994 to 2023: The largest main truss for domestic coke ovens, weighing 1,000 tons and requiring two lifting machines to lift it 120 meters high, was successfully installed

Ten years of rapid development in chemical processing equipment – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. Everyone should focus on safety and know how to handle emergencies. ********************************************* Recently, at the site of the Hebei Huafeng coke oven flue gas treatment project, which was constructed by China Fifth Metallurgical Group, the SCC17000TM and SCC15000TM machines managed to complete the installation of the main truss on the machine side of Coke Oven No. 6 in just 7 hours, thereby providing strong support for production and the stability of the coke ovens. The clear distance between the track sliding guide of the machine-side coke pushing car at Coke Oven No. 6 and the mountain slope serta the pipe rack is 8.9 meters; there is neither enough space for assembling lifting equipment nor sufficient lifting area, and the traditional lifting methods cannot be used either. As a result, the construction difficulty increases significantly. In addition, to avoid disrupting production, the owner only provided 10 hours as a window for the lifting operation.
To this end, the project team and expert group, together with the construction crew, professional engineers in lifting machinery, and operators, conducted numerous discussions and innovations on the lifting plan. Meanwhile, BIM technology was utilized to simulate environmental parameters and the entire lifting process, allowing for dynamic analysis of the collisions between the steel truss and the sliding contact wires as well as the furnace body under various conditions during lifting at heights, thereby optimizing the operational procedures and the selection of crawler cranes. It was ultimately decided to perform segmented traction, assembly and alignment, as well as final shaping of the truss outside the pusher car’s slideway. An SCC15000TM unit was installed at the platform located between the pusher car’s slideway and the furnace body, while an SCC17000TM unit was placed at the intermediate platform to enable lifting using two machines.

Since early February this year, the project team has begun to plan the travel route for the crawler crane, and has worked on preparing the foundation at the lifting site to construct a walking platform. In mid-March, the trusses to be lifted were assembled and aligned, and by the end of April, the overall formation of the trusses as well as quality inspections were completed. On April 25, two ultra-heavy-duty crawler cranes arrived at the site for assembly, and they became capable of lifting loads on May 6. At 9 a.m. on May 7, the lifting operation officially began. The SCC15000TM and SCC17000TM work together to lift the main truss, which weighs 440 tons and is 120 meters long, around the slide wire; it is then moved to above the tracks of the machine-side coke pusher, and after that it continues to move while the lifting position is adjusted to stabilize the truss. Subsequently, the SCC15000TM increased its counterweight to 370 tons, and together with the SCC17000TM, it lifted the truss onto the gate-type supports on top of the furnace, thus positioning it in place and completing the lifting process.
This lifting operation represents the first time that a domestic coking enterprise has used a large-tonnage crawler crane to lift super-large components while the coke oven is in operation; it also serves as a clear demonstration by China MCC Group of its commitment to \"MCC speed, MCC service, and MCC quality\". In the future, the Hebei Huafeng coke oven flue gas treatment project will also strive to become a high-quality project that can stand the test of time, establishing a fine reputation in the industry.
