Three Terex cranes have been used to lift a pedestrian bridge – almost 200m in length – in Rotterdam, the Netherlands. Two AC 500-1 all-terrain cranes and one CC 2500-1 crawler crane worked together to place the bridge into position.
Transporting cranes of this magnitude to the site posed somewhat of a challenge for the team from Dutch crane service supplier Wagenborg Nedlift. However, the machines’ user-friendly designs helped the crew to assemble them almost in an extremely short timeframe.
The AC 500-1 cranes were driven to the site by Wagenborg operators with support from three transport vehicles. Within an hour of their arrival, the all-terrain cranes were ready for work. Delivery of the CC 2500-1 was a slightly more complicated affair; 29 trucks were needed to transport the giant to the bridge’s location. Even so, four team members were able to erect the crawler into its superlift configuration within just one day.
The architecturally striking bridge – known locally as ‘Netkous’ meaning ‘fishnet stocking’ – is a latticed, tubular structure. As the neighbouring motorway and railway line had to be closed during the lift, the Wagenborg team had only two days to install the bridge.
The bridge had to be lifted in two sections. The larger section was 100m long and weighed 350 tonnes whereas the smaller section measured 90m and weighed 325 tonnes. The trio of Terex cranes lifted the bridge’s two sections 20m into the air and placed them onto their foundations.
The CC 2500-1, equipped with its spreader attachment, was positioned on one side of the construction sections, and the AC 500-1 cranes were placed on the other. The Terex crawler operated at a working radius of 20m-25m, whilst the all-terrain cranes had functioning radii of up to 16m.
“We opted to use the three Terex cranes on this project because they had precisely the capacities we needed to complete the two required lifts safely and reliably within the given timeframe,” said Jack Bienen, project manager from Wagenborg Nedlift.
