ALE has successfully demonstrated its multi-service capabilities when performing the load-out and installation of the arc bridge, weighing 1,200t, using the Mega Jack 800 in Antwerp, Belgium, for De Vlaamse Waterweg.
ALE had only one weekend to complete the operations; this was only possible by using the Mega Jack 800 as operation time is reduced.
In order to complete the different techniques and operations, ALE ensured logistics were optimised to work with the limited room available on the barge. The bridge deck and arches were transferred from the construction supports onto 40 axle lines of SPMT with 4 PPUs in a configuration of 4 x 4 file 4/6 row.
ALE then loaded-out the bridge deck, longitudinally from the fabrication site at Gent. The bridge was then transported 75km with the SPMTs by barge to Antwerp on the Scheldt River. In order to pass under the low bridges on route, the arches of the bridge were positioned in pieces on top of the bridge deck with a restricted height.
