Sarens has been executing complex lifts at a fertiliser project site in Zambia, the longest components measuring 80 m long.
Tight roads and space constraints were constant obstacles throughout the project, as were periods of heavy rainfall.
Sarens opted for the Terex Demag CC 2900-1, equipped with an S7 boom system and 300 tonnes of superlift ballast. Initially configured with an 84 m main boom, it was later reconfigured to feature a 108 m main boom, with shorter boom lengths used for heavier lifts and extended reach saved for specific tasks.
As the project progresses, Sarens will again reconfigure the crane so that it has an 84 m main boom and a 54 m luffing jib. This setup allows for efficient hoisting of key equipment, such as compressors, tanks, columns, and modules – with the longest column reaching 80 m and the heaviest lift at 250 tonnes.
A combination of the S7 boom system and 300 tonnes of superlift ballast, mean that a 750-tonne lattice crawler crane was not needed. The CC 2800-1, in tandem with a client-supplied Sany 250-tonne crawler crane, performed complex tailing tasks with exact slewing and crawling movements to position the loads safely.
Last week, HLPFI reported that Sarens had completed its role in the replacement of a bridge over a Belgian highway.
