The route up to the windy heights of Viento Blanco Wind Farm is 10 kilometers long and leads past an active volcano. It follows a narrow winding mountain road lined with trees and rock overhangs and with gradients of up to 18% uphill and 13% downhill. Seven Vestas V 112 wind turbines are being installed at the wind farm. The rotor blades were transported over a distance of 80 kilometers from the Guatemalan port of Puerto Quetzal to the Viento Blanco site by Daco Heavy Lift using an FTV 300 blade transporter from Goldhofer.

An additional challenge was the wind acting on the rotor blades in the raised position, when they are up to 50m high. Consequently, the company had a wind force specialist continuously monitoring the FTV 300’s integrated anemometer. In order to ensure that the rotor blades are always correctly positioned for the optimum wind attack angle, the FTV 300 has a 360º pivot system that permits the attached blade to be rotated around its own axis as required. This combination of flexible tilt angle and blade rotation allowed the tricky mountain road to be negotiated. Passages under the numerous overhead power lines were handled by reducing the angle of tilt. Each of the 21 rotor blades made the journey in three hours.

The first 70 kilometers of the trip were relatively easy, with motorway driving all the way. Handling the last 10 kilometers, on the other hand, involved a total of over 16,000 man hours for Daco Heavy Lift, which completed the delivery of all the rotor blades in 40 days.
