At 15:00 on February 11, the pellet mixing bin for the polypropylene unit of the Yulin Chemical Phase II project was successfully hoisted into place. This lifting operation was successfully carried out through coordinated planning and efficient collaboration by the Engineering Management Department, the Polyolefins Department of Shaanxi Coal Group Yulin Chemical Company, along with Hualu Engineering Technology Co., Ltd., thus fulfilling the assigned lifting tasks. It is reported that each silo to be lifted this time has a diameter of 7.5 meters, a total height of 30 meters, and a weight of around 26 tons; it needs to be precisely placed on a frame structure 15 meters high. Serving as the \"final stage\" for producing qualified granule products in polypropylene plants, this silo serves both storage and homogenization functions. With a capacity of 1,000 cubic meters per unit, it can store 500 tons of granules, thereby improving the quality rate of the products. It also provides essential buffering and adjustment capabilities to ensure that the plants and the downstream finished product storage areas can operate at full capacity. Furthermore, given the large diameter and high height of the cylinder involved, as well as the fact that the operation was carried out at a great height, a 700-ton main crane was used for lifting, along with an 80-ton auxiliary crane; this ensured a smooth placement of the component throughout the process, resulting in a successful completion on the first attempt. This successful lifting not only provided valuable, replicable and applicable experience for the installation of the subsequent 55 large-scale devices, but also laid a solid foundation for achieving the annual construction targets.
