Snow was cleared from the packing areas so it wasn’t compacted or moved when the load went over it.


1m x 200mm x 100mm hardwood timber blocks were used for packing. Rapid’s Paul Barber said, “100mm timbers work great for bird caging down the load and they are not too heavy for manual handling.”


Four RRS riggers met the varied challenges of the day.


hardwood timber blocks, the skidding track was placed under the PSP using a telehandler. It was then jacked down onto the skid shoes before being slid across the foundation slab. Te unit was then jacked up so tracks could be removed prior to final lowering into position. Barber explained that the HT300 was chosen as it is capable of supporting loads without the four 6m sections of tracks being fully supported, eliminating the need for support beams or extra packers. Hydra-Slide alignment shoes were also on standby should there have been a requirement to carry out any final positioning.


Te power lines were so close to the final position that it was not an option to use a mobile crane to unload the unit. Had a crane been the only option, Nation Grid would have needed to isolate the power. Tis was the first time this method of offload had been used on the project and it was deemed a success. Without the skidding system it had looked impossible to deliver a modular solution to the site and it was believed that a traditional building would need to be constructed and the equipment populated onsite. y
