ALE’s innovative Mega Jack 800 scores hat-trick with STS crane jack-ups in Barcelona
ALE has used its award-winning Mega Jack 800 system to heighten and jack-up three STS crane, weighing 1,390t each, in Barcelona, Spain.
ALE was sub-contracted by ZPMC to jack-up the cranes almost 6m high, so the cranes could be extended at the Barcelona Europe South Terminal (BEST). Due to the ongoing activities on-site and the tight timeframe, ALE had to find a solution that had the high capacity yet small footprint and could execute the jacking quickly whilst minimising site disruption.
ALE used the Mega Jack 800, with 800t capacity in each of the four towers, to perform the jacking in 12 stages. A jacking frame was also deployed to support the crane structure.
