The wind towers and foundations for a Canadian wind farm will be produced using two DAVI 4 roll machines, which are capable of bending plates of high-tensile steel up to 150-mm thick and 3,000-mm wide. The machines are equipped with Davi’s patented High Productivity Package System. “By choosing Davi plate rolls,” says Orazio Davi, President…
How are wind turbine towers changing?
Every horizontal-axis wind turbine needs a tower. Turbines erected in the 1970s and 1980s may have been perched on lattice towers, a design that can scale to 200 ft and more. However, for the protection of the maintenance technicians who must climb the towers, it makes more sense to build them from rolled steel. These…
GE: a busy bee with turbines and towers
Looks like GE’s been busy lately. But for one of the world’s largest companies that in itself is nothing new.
Steel facility in Kansas to produce new wind tower
A wind tower manufacturing plant is planned for Ottawa, Kansas. Schuff Steel Company, a subsidiary of Schuff International, Inc.— a family of steel construction companies — is moving ahead with their plans.
Cylindrical Towers are the Secret to Capturing More Wind
A classical image of fluid flowing around a cylinder shows it speeding up at the sides and slowing or stagnating at the front and back. This let Majid Rashidi, Professor of Mechanical Engineering at Cleveland State University, realize that placing wind turbines in the naturally forming high-speed areas at the sides would let them generate…
Two to build wind towers
To serve North American markets, Martifer Energy Systems and Hirschfeld Wind Energy Solutions say they will form a joint venture to manufacture wind towers and related components in the U.S. The joint venture, Martifer-Hirschfeld Energy Systems LLC, will be equally held by each party. The company will develop a factory in San Angelo, Texas, to…
Where to place wind towers wins $10,000 prize
A clever idea from a French team of engineers and architects is to build vertical-axis wind turbines into existing towers that carry high-voltage power lines. The idea was good enough to win a $10,000 Metropolis Next Generation Design Prize. The team, Julien Choppin, 31, and Nicola Delon, 31, are partners in Paris architectural firm. Also…
