WINDSPIDER
One solution – many opportunities
WindSpider is an innovative and cost-efficient lifting solution for installation and major component replacement of onshore and offshore wind turbines. Our self-erecting lifting technology is unique in the way it utilizes the wind turbine tower as support for the crane structure, which results in many attractive features and benefits, such as:
- Eliminating issues with relative motion between the WindSpider crane and the wind turbine.
- Solution scalable to over 1500 tonnes of effective lifting capacity, with no height restrictions.
- Increased operability, as WindSpider can operate at very high wind speeds.
- No requirements for design changes to wind turbine or tower.
- Modular and practical design that allows for effective transport by road or sea.
- Compatibility with existing vessels and barges, providing a cost-efficient alternative to purpose-built vessels.
- A cost-efficient solution to complying with the Jones Act requirements in the United States.
Our products include the WindSpider Crane, the Dolly Crane and the Blade Tool.
