The first modular lifting task for the Inner Mongolia Rongxin polypropylene plant project was completed successfully; \"construction without outstanding tasks\" facilitates project development

Thread Content

On January 23, the framework staircase in the blending bin of the Inner Mongolia Rongxin Polypropylene plant, which is under the construction responsibility of the Inner Mongolia Rongxin Polypropylene project team, was hoisted into place, marking the successful completion of the first modular hoisting task for this project. This not only lays a solid foundation for the modular installation of steel structure units in subsequent phases, but also represents a systematic test and successful application of the \"construction without residual tasks\" concept in the field of modular installation. The steel structural staircase module to be lifted this time is 10 meters long, 4 meters wide, 22.85 meters high, and weighs 95.56 tons; it is to be installed at a height of 16.1 meters above the ground. To ensure that the lifting operations are carried out safely, accurately, and efficiently, the project’s technical team adheres to the concept of \"construction without leftover tasks.\" Regarding key aspects such as plan formulation, equipment selection, site layout, and implementation of safety measures, they strictly follow the management principle of achieving excellence from the start and maintaining high standards throughout the process. Every stage of construction is aimed at being completed perfectly, without any residual issues or unfinished tasks, thus ensuring smooth progress in the project’s development. During the preparation phase for lifting, the project’s technical team accurately calculated the stress levels on the modules as well as the performance parameters of the lifting equipment, and devised a specialized lifting plan. The lifting operation was carried out using a 400-ton crawler crane as the main lifting device, with a 200-ton truck crane used to assist in the process. At the same time, core aspects such as the positioning of cranes, the selection of lifting lugs and rigging, and the setup of working areas at connection points are repeatedly optimized through simulation exercises, to ensure accurate data and reliable plans. This helps to avoid uncertainties and potential safety risks during construction, minimize hazards associated with work at heights, and achieve precise control over construction costs.
