Mammoet adds towers to Mega Jack fleet

By D.Ann Shiffler30 March 2021

Developed by ALE in 2014, the Mega Jack 800 has a capacity of 800 metric tons per tower.

Mammoet has added ten new towers for its Mega Jack 800 system, bringing its Mega Jack 800 tower fleet to 22. These machines are used on such projects as civil infrastructure renewal, port expansions and petrochemical facility construction. 

Introduced by ALE,  the Mega Jack 800 provides significant lifting power (800 metric tons per tower) within a compact footprint that minimizes its impact on other site operations.  

This allows projects such as bridge installations to be performed quicker – sometimes in a matter of just a few days – and work to expand or heighten port cranes to be completed with less disruption to the operations around them, according to Ronald Hoefmans, Head of R&D and Fabrication at Mammoet. The strong and versatile lifting system  can be deployed quickly with

the majority of work undertaken at ground level. 

“More Mega Jack 800 towers means more possibilities for our clients to save time, operate more safely and reduce disruption across a range of different projects,” Hoefmans. “One of the real benefits of the Mega Jack 800 system is its flexibility, and this has allowed it to make a real impact not just for civil and port projects but for the likes of the nuclear decommissioning and OGP industries too. Because it is controlled remotely by computer, the system allows highly accurate, simultaneous operation of the towers, which is not possible with manual jacking systems. Importantly, this also minimizes the need for interaction with the machinery to help optimize safety on site.” 

The Mega Jack 800 system is just one part of Mammoet’s range of jacking solutions, from traditional climbing jacks to the 300-metric ton per tower capacity Mega Jack 300 and 5,200 metric ton per tower capacity Mega Jack 5200.
