CRAWLER CRANES Ӏ LATTICE BOOMS
RECORD BREAKERS
World records are being broken by the current generation of lattice-boom crawler cranes; and it’s not just for show – bigger lifts in sectors such as wind energy are demanding higher capacity. Daniel Searle reports.
Lattice-boom crawler cranes are designed to combine strength with mobility. Increase that strength, and the crane offers more versatility – as well as potential time savings on certain lifting jobs. A new standard was set earlier in the year, says China-based
Zoomlion’s
ZCC89000 claimed two lifting world records at the start of this year
manufacturer Zoomlion, when its 3,600-tonne ZCC89000 crawler broke two world records: for the heaviest single lift, and the fastest lifting speed. The capacity of the crane
mirrored the scope of the project. The records took place during the
installation of three slurry bed reactors in Zhejiang Province, as part of the construction of a slurry bed residue hydrogenation plant forming part of Zhejiang Petroleum & Chemical Co. Ltd.’s No.3 New Material Engineering Project. The project is the largest of its kind within the Chinese refining and chemical integration sector, says Zoomlion, and also the largest investment in a single industrial development of any kind. Once complete, the
petrochemical facility will have an annual refining capacity of 40 million tonnes of oils, 11.8m tonnes of aromatics, and 4.2m tonnes of ethylene. Big numbers, which require big equipment – which required a big crane. Each slurry bed reactor – the largest single-weight forging and welding hydrogenation reactor – has a net weight of 3,037 tonnes, and a net height of 67.57 metres. Zoomlion completed the installation of the three reactors in six days, advancing the construction schedule by two months. The lifting moment of the crane reached 92,800tm with a counterweight of 3,160t. The model also offers six
travel modes, notes Zoomlion, including its ‘T-shaped’ travel path
