en.Wedoany.com Reported - UK heavy transport company Collett & Sons has completed the transportation and installation of a 202-tonne Hyosung transformer from Goole West Dock to the Brinsworth National Grid substation in South Yorkshire.

The transformer was received at Goole West Dock and directly unloaded onto Collett's 350-tonne Scheuerle truss frame trailer configuration, which used 20 axle lines. After securing the transformer, the transport distance was 36 miles (57.9 km) to the Brinsworth substation. The overall transport combination measured 67 metres in length and weighed 410 tonnes.

Extensive preparatory work was carried out before transport, including modifications to the site entrance, road widening, temporary removal of fences and street furniture, and improvements to service routes to avoid using local tunnels. During ground preparation, full matting was laid in the cofferdam area to reduce ground bearing pressure during unloading operations. Detailed engineering designs, lifting plans, and ground bearing calculations were developed for all these tasks.

Upon arrival at the site, Collett's heavy lift team executed a complex unloading and positioning process: the transformer was first unloaded onto steel stools, then lowered onto a turntable and rotated to fit the limited working area. It was then jacked up onto skid rails for the first phase of movement, repositioned after moving 14 metres, and then underwent a second phase of vertical skidding (32 metres) before finally being installed in place on the foundation.

Collett completed the project within six days. Last month, the company completed the transport and installation of another Hyosung transformer, weighing 89.9 tonnes, destined for National Grid's Bicker Fen substation in Lincolnshire.
