King Lifting used a 350-tonne capacity Terex AC 350/6 all terrain crane to lift and place the bridge.
A 40-tonne AC 40/2L and 60-tonne AC 60/3L were in support to help assemble the bridge. It took six days to assemble the bridge and a seventh to lift it into place. King will be back on site after the event to dismantle and remove the structure.
“At King Lifting we operate a fleet of over 100 cranes of which 54 are Terex models,” said commercial director Tristan King. “Last year’s purchase of an AC 350/6 has proved to be a great bonus to our business. Its compact dimensions and powerful lifting capacity are suited to a broad field of applications, particularly when it comes to lifting heavy loads in tight spaces.”
Arriving directly from King Lifting’s West London depot, the three cranes, and the support vehicles carrying the separate bridge sections, were driven off the main road, across the fields via a pre-laid 500m trackway, and down to the riverbank where the bridge was to be erected. A concrete-based area cast with steel cross-sections provided support for the cranes’ outrigger jacks.
The AC 350/6 was configured using 116.6-tonne of counterweight and 54.2m of main boom with Superlift attachment at 28m radius to lift the 23-tonne steel footbridge across the river.
