2000-ton crawler crane used to lift and install the high-pressure discharge tank for the polypropylene unit in the Tarim Phase II ethylene project

On July 13, at the construction site of the Tarim Phase II ethylene project, a 2,000-ton crawler crane made its debut in lifting operations in the polypropylene plant area. It is reported that the heavy item lifted this time is one of the core equipment in the polypropylene plant – the high-pressure discharge tank. The equipment weighs 191.8 tons, with a total lifting weight of 242 tons. It needs to be installed at a height of 4.6 meters, with a lifting span of 54 meters. The lifting operation requires precise maneuvering through narrow passages, across the vapor-phase reactor and the polymerization pipeline tray of the polypropylene plant, in order to achieve accurate positioning. Following the successful completion of its tasks and departure of the 4000-ton crawler crane, this 2000-ton crawler crane took over seamlessly as the main lifting device for the project construction. Not long ago, a 2000-ton crawler crane successfully completed the “eight major lifting” operations at a full-density polyethylene plant. After going through the disassembly transition, we arrived at the polypropylene plant area. At 23:00 on July 12, the assembly, debugging, and weight adjustment tasks were successfully completed. On the morning of July 13, the first lifting operation for the 2,000-ton crawler crane polypropylene plant officially began. It is understood that to complete this task, the project team optimized the lifting plan on seven occasions in the preliminary stages and carried out simulation drills. At the lifting site, a 2000-ton crawler crane lifted the high-pressure discharge tank high into the air; it took 90 minutes to position the tank accurately and successfully in one attempt. This first attempt was a success, and it provided valuable practical experience for the subsequent lifting of tubular reactors and product purification units.
