184t Transformer Transport by Allelys Group
Allelys Group have recently transported, offloaded, and installed a transformer weighing 184t. The cargo was received at Ipswich Docks onto a 12-axle flat top trailer and shunted to a temporary storage area.
The transformer measured:
- Length 8.7m
- Width 5.4m
- Height 4.8m
The 59 miles route to Burwell, Cambridge, engineered by the Allelys team, included the temporary closure of the Orwell Bridge to enable the 18 axle, 200t capacity girder frame transport to cross without any other vehicles on the bridge at the same time.
Working alongside Highways England, Allelys arranged temporary traffic management on the A14 to remove the central reservation barrier and with two lanes closed on each side, the girder frame was able to cross over, travelling against the normal flow of traffic. The transport travelled at approximately 12 miles per hour over the journey and had a police escort to make the process as smooth and safe as possible.
The heavy transport needed to negotiate the intricate road network through the town of Burwell before delivery to the substation. Residents in the town had been requested not to leave cars parked on the route through the town.
Once on site, the transformer was jacked up using synchronised climbing jacks and positioned onto a turntable to be rotated, skidded into the containment area, and then jacked down into its final position.
The in-house engineering team supported the project to ensure that the abnormal load was able to successfully travel through the selected route by completing route surveys and swept path analysis. They also engineered a lift plan for the crane work on site.
“This project was particularly interesting to work on due to the route involved. It was certainly impressive to see the girder frame travelling solo across the Orwell Bridge,” explains Zac Smout, Project Manager at Allelys.
“The knowledge and experience within the team, alongside the Allelys equipment fleet, were all critical elements to the success of the project.”
