Osprey Group and Enerpac Raising 1,400t Deck with 1.5m Inclination
An eight-point Enerpac Jack-Up System has enabled Osprey Group, a leading logistics and heavy lift specialist, to complete a bridge deck installation with one single movement. Even with a 1.5m inclined height difference at either end of the bridge deck, the Enerpac JS-250 Jack-up system successfully lifted the 1,400-tonne load.
Completed before the recent UK shutdown, the 74m long x 16m wide bridge deck replaced an existing bridge over a dual carriageway. Using the JS-250 Jack-Up Systems allowed the bridge deck to be built next to the highway and transported on Self-Propelled Modular Transporters (SPMT) to the installation site. The Jack-Up units were delivered smoothly to the deck construction site by flat-bed trucks, which meant no need for specialist transport.
Installation of the bridge was completed over a weekend. With four JS-250 Jack-Ups at either end, the bridge deck was lifted and then transported 500m to the bridge abutments on the dual carriageway by SPMTs. Accurate positioning of the bridge deck to 6.8m at its highest inclined point with the Enerpac Jack-Ups was critical. Once in position, SPMTs were used to provide the final height positioning.
“Enerpac JS-250 Jack-Up units are a go-to piece of equipment for us. They’re easy to deploy and operate,” said Ryan Ebanks, Project Engineer, Osprey Group. “Given the size of the bridge deck in this instance, and the need to incline it by 1.5m, the Enerpac Jack-Up was a perfect choice. Without them, we might have had to use multiple cranes.”
