【Haichuan Expands Horizons】20 Cranes Work in Unison to Lift a 500-Meter-Long Pipeline
Thread Content
20 cranes worked in unison to lift a 500-meter-long pipeline. A certain heating and high-temperature water supply pipeline project spans approximately 12 km in length; as part of this project, it was necessary to lay a 500-meter-long thermal pipeline at a depth of 17 meters underground, which posed significant challenges and became a bottleneck for the project. After multiple rounds of detailed calculations regarding load distribution and discussions for verification, the project team and the two lifting companies decided to use a total of over 20 units of XCMG’s model series featuring capacities of 25 tons, 50 tons, and 80 tons – namely the XCT25, QY25K5C, QY50K5C, and XCT80 models. These units were arranged evenly along one side of the 500-meter-long pipeline, at intervals of 26 meters each, so as to work together to accomplish this challenging task. During construction, more than 20 cranes moved their hooks up and down and swung their arms in sync, working together with the pipe guiding machine to lower the pipes steadily. Precise and efficient construction reduced the time by 4 hours compared to what was expected.
Lifting with multiple machines – something most people can’t even imagine
The submarine pipelines are longer and have a greater height difference; isn’t it still the case that welding is done on the pipe-laying ship before the pipelines are lowered one after another?
Yes, why not consider the pipeline-laying model used for offshore oil pipelines? Or it could be the long-distance pipeline approach. According to this report, the pipelines are assembled on the ground; after pressure testing is completed and anti-corrosion and insulation measures are applied, then they are laid. Are there different process requirements for these two methods?
It’s difficult to synchronize so many cranes.
