The Netherlands-based transport engineering and heavy lift specialist Mammoet has introduced its Mega Jack 10000.
The system provides 10,400 tonnes of lifting capacity per tower, up from 5,200 tonnes previously, without increasing the footprint of the tower base. As a result, less steel is required to support structures as they are lifted, and the heaviest lifts will be able to start closer to ground level. Moreover, Mammoet explained that because the system’s capacity per tower has doubled, fewer towers will be needed to lift larger loads, meaning smaller foundations are needed – beneficial both financially and in terms of scheduling.
The Mega Jack 10000 also boasts a 5 m jacking beam with three connection points, allowing for load distribution across eight Mega Jack base units: four at the corners of the tower, and four at the centre of each side.
Large jacking projects require starter beams, which are used to connect these jacking towers together and distribute the load. One Mega Jack 10000 tower can lift that of two Mega Jack 5200 towers, so supporting steel can now be smaller, thinner and require less engineering to develop. Additionally, thanks to an upgrade of its control systems, Mammoet’s towers can now monitor lift positions to one hundredth of a millimetre.
The new system will be utilised by the offshore oil and gas sector, for the manufacturing of heavy topsides, and the renewable energy industry for the fabrication of converter stations.
Earlier this month, HLPFI reported that Mammoet had launched the world’s strongest land-based crane, the SK6000.
