SECTOR SPOTLIGHT Ӏ BRIDGES
decided to deploy: Sarens' barge Caroline 26 ballast pumps (600T/h) six hydraulic winches (50 tonne) SPMTs in various configurations (6x10 axle-lines, 2x16 axle-lines, 2x12 axle-lines) RoRo ramps of 2.75m, 5.8m, and 9m. Some equipment was shipped on the
barge, while the rest was transported by road. Each bridge section weighed about 1600 tonnes and measured 92m in length, 18m in width, and 38m in height. Due to site-specific requirements in Rotterdam and Flushing, different SPMT configurations were used. In Rotterdam,
limited space and ground pressure led to a setup of 6x10 axle-lines, while in Flushing, 4x16 axle-lines were required due to ground pressure limitations. Extensive ballasting was necessary in both Glasgow and Flushing to maintain the correct draft and trim, compensating for tide and load variations during operations. The south bridge in Rotterdam was
transported to the quayside using six ten-axle SPMTs, lifted by three shear legs, and loaded onto Sarens' barge Caroline. After securing the load, the barge was towed to Glasgow, where pre-assembled SPMTs (two sets of 12- axle units) were used to move the bridge
to its final position on temporary jacks. The north bridge in Flushing, Netherlands, followed a slightly different process. It was transported to the quayside using 32-axle SPMTs, driven onto the barge during a load-out operation, and transported to Glasgow. The installation sequence in Glasgow mirrored that of the south bridge. The project involved a crew of 14 individuals, working in double shifts to minimise the barge's presence in the river navigation channel in Glasgow. Due to limited water depth, a ramp structure on piles bridged the gap between the barge and quay, with the longest gap being around 18 metres.
Who: Mammoet / McConnell Dowell. What: Accelerated Bridge Construction (ABC) approach to installing an elevated rail bridge over a busy road in a built-up area whilst minimising traffic disruption. Where: Melbourne, Australia.
Contractor McConnell Dowell commissioned Mammoet to fabricate, transport, and instal an elevated rail bridge over a busy road in an urban part of Melbourne. For this Mammoet utilised SPMTs in combination with its Enerpac JS500 jacking system. First, the
