4,000t gantry towers lift the top of the 1,600t 129m high splitter column, while the CC6800 'tails-in' the base

The project includes 125 heavy lifts, the most challenging of which was installing the 129 metre long, by 10 metres wide 1,6000 tonne splitter. The company chose to use a twin tower gantry lifting system configured to handle loads up to 4,000 tonnes. A 1,250 tonne Demag CC6800 with 850 tonnes counterweight was used to ‘tail in’ the column, as the hydraulic jacking system lifted the top of the column.
