Allelys has engineered an innovative solution to minimize site disruption during the installation of a turbine and generator components through the roof of a turbine hall, situated at a height of 22.3m.
The 160te turbine, measuring 7.8m (l) x 5.35m (w) x 4.6m (h), arrived at Goole docks, where Allelys efficiently discharged it using the LG1550 mobile crane. Following temporary storage on stools at the port, Allelys built a 24-axle girder frame trailer around the cargo for self-loading in preparation for transportation to Skelton Grange.
To address site challenges, including negotiating structures like Wyke Beck Bridge and Effluent Culvert, Allelys designed a specialized solution involving a larger and lighter frame than typical for units of this size and weight. The transportation phase included a night closure on the A1, enabling the transport to cross over and join the M1.
At the site, the turbine was transshipped onto a 12-axle SPMT due to restricted space, then lifted into the turbine hall using the LG1550 crane. A 96te generator was also received at the site, temporarily stooled off, and transported to the crane location for lifting.
Navigating construction restrictions and precise planning, Allelys overcame challenges in modifying the crane location and positioning outriggers for non-load-bearing areas. Rigged in a luffing jib configuration due to the building’s height, the LG1550 lifted and installed both components with meticulous precision, ensuring successful placement in their final positions.
