European Air-Crane, an affiliate of Erickson Air-Crane, has assisted Vestas Wind Systems of Denmark in erecting a dozen three-megawatt wind turbine generators near the Italian mountain village of Ricigliano.
An Erickson S-64F Aircrane flew with a 400-foot longline to deliver 36 turbine blades, each measuring 144 feet long and weighing 15,800 pounds. Narrow and steep roads prevented trucks from carrying the blades. The S-64F flew the individual blades approximately nine miles to the construction sites, allowing their transfer to be completed in less than four days.
Closer to home, an Erickson S-64E Aircrane was instrumental last December in shoring up a section of sewer pipeline exposed by erosion from record rainfall in coastal Washington State. The heavy-lift helo carried and deposited 400 tons of crushed rock to the pipeline exposure, which lay within a large gully inaccessible by any ground transportation mode. “We realized the urgency of the situation and knew that the pipeline was vulnerable to rupture and could possibly contaminate a waterway known as a salmon spawning area,” said an engineer with KLB Construction, a civil highway contractor in the Pacific Northwest.
