According to Zoomlion, its 3,600-ton ZCC89000 crawler crane broke two world records for the heaviest single lift and fastest lifting speed during the installation of three slurry bed reactors in Zhejiang, China. This lift was part of the construction of a slurry bed residue hydrogenation plant.
The slurry bed reactor has a net weight of 3,037 tons and a net height of 67.57 meters. It plays a crucial role in the slurry bed residue hydrogenation plant, which, upon completion, will enable the facility to achieve green, low-carbon, and precise refining operations with high efficiency.
Zoomlion has implemented eight significant upgrades to the 3,600-ton crawler crane. These improvements and various hoisting technologies have successfully addressed complex challenges such as considerable heights, heavy weights, restricted lifting areas, and long-distance load travel.
The total hoisting weight of the three reactors amounted to nearly 10,000 tons, and the ZCC89000 completed the installation in six days. The lifting moment of the main crane reached 92,800 tm with a counterweight of 3,160 tons. The model offers six travel modes, including the “T-shaped” travel path allowing it to achieve a greater pickup range in a narrow operating area.
This lift advanced the construction schedule by two months.
The mega-scale project is currently the largest of its kind in the field of refining and chemical integration under construction in China, according to Zoomlion. Upon completion, it will become a petrochemical industrial base with an annual refining capacity of 40 million tons of oils, 11.8 million tons of aromatics, and 4.2 million tons of ethylene.
