The CC 8800-1 model, with a maximum lifting capacity of 1,600t, was used to lift a 407t polythene reactor at the Dagang Ethylene Plant in Dagang. The crane was built up in SSL 108m configuration and installed with a 300t counterweight, 60t central ballast and superlift counterweight and superlift counterweight carrier with a combined weight of 640t.
A tandem lift was carried out on the load, with a Terex-Demag CC 2500 with a capacity of 450t as the assist crane. This allowed the lift, with a total weight of 440t with hooks and cables, to be completed in one hour once all the preparation work had been finished.
The project is being carried out by the Fourth Company of Sinopec, part of Sinopec Corp., ranked fifth in the world for ethylene capacity. The reactor measures 47m in length and 8m in diameter, and will help the fully operational plant produce one million tonnes of ethylene a year. It was transported to the Dagang site from Xingang Port with a truck mounted with a crane leading the procession and lifting power cables along the 40km route clear of the reactor.
