Zoomlion's 3600-ton crawler crane successfully lifted three slurry bed reactors from January 3 to 8. The reactors were part of the 'three vessels, three points and two towers' of Zhejiang Petrochemical New Materials Project No. 3 3 million tons/year slurry bed residual oil hydrogenation plant. This achievement set a new record for the weight and speed of a single lifting by a crawler crane.
 The slurry bed reactor lifted this time is the core equipment of the No.3 slurry bed residue hydrotreating plant. It has a net weight of 3037 tons, making it the world's largest single-weight forged and welded hydrotreating reactor. There are many challenges associated with lifting this reactor due to its height, weight, narrow lifting site, and the long distance the crane must travel with the load. Zoomlion, in collaboration with the construction team, upgraded the 3600-ton crawler cranes in eight locations and incorporated several technical innovations in lifting to effectively address the aforementioned issues.  Zoomlion's 3600-ton crawler cranes lifted all three sets of 3000-ton slurry bed reactors, setting a global record for the heaviest lifting by a single crawler crane. The total lifting weight was nearly 10,000 tons, and the crane achieved a record speed of lifting nearly 10,000 tons in just six days as the main crane. Simultaneously, the successful removal of three slurry bed reactors advanced the construction period of the entire plant by two months, resulting in significant economic and social benefits.  Reports state that the main crane, Zoomlion 3600-ton crawler crane, has a lifting moment of 92,800 tons of meters and a counterweight of 3150 tons. It also has six travel modes, including the first 'T' travel mode, which allows for a greater range of movement in narrow operating areas. This crane is the first of its kind, both domestically and internationally, that can lift a 3,000-ton slurry bed hydrotreating reactor.
