— the 1st WindSpider unit with a 150t capacity, customized for blade and nacelle component replacement on +13MW wind turbines
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 liftingcapacity, 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 effectivetransport 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 range of products, described below, includes: the WS Dolly Crane, WS Blade Tool, the WS Crane and the WS Clamp Deck

WindSpider
Dolly Crane
Efficient crane system for controlled removal and installation of nacelle components
- Suitable for onshore & offshore operations, on fixedand floating turbines.
- Eliminates the need for tow-to-port for repairs of floating wind turbines, by allowing for cost-saving component replacement on site.
- Travels up and down the WindSpider structure built around the turbine tower, allowing for controlled replacement of components.
- Ideal for maintenance jobs with a lifting capacity of up to 400 tonnes.
- No lifting height limitations. Very good operability at high wind speeds.
- Quick mobilization time and a cost-efficient solution for offshore component replacement.
WindSpider
Blade Tool
Superior solution for controlled installation and exchange of turbine blades.
- Suitable for onshore and offshore operations, on floating and bottom-fixed wind turbines.
- Travels up and down the WindSpider structure built around the turbine tower, allowing for controlled installation and exchange of blades, even in very windy conditions.
- Lifting capacity that can be scaled to match the requirements of future generations of wind turbine blades.
- Can be adjusted against the hub in all directions.
- Offers safe and steady control of the root-end of the blade while connecting to the hub.
WindSpider
Crane
Winch luffing crane prepared for next generations of wind turbines
- Suitable for installation of wind turbines onshore, inshore & offshore (bottom-fixed and floating).
- Lifting capacity that can be scaled to over 1500 tonnes with no lifting height limitations.
- Can perform lifting operations on floating wind turbines on site, at sea.
- Onshore & quayside operability in high wind speeds.
- Compatibility with existing vessels and barges.
WindSpider
Clamp Deck
Solution for safe and cost-efficient MCR operations on existing WTGs
- Suitable for offshore operations, on floating and bottom-fixed wind turbines.
- WS Clamp Deck can be installed — in one lift — on a WTG and provide a temporary working deck for the purpose of carrying out MCR operations.
- Built in aluminum and steel, the Clamp Deck offers optimal design and can sustain weight of the WindSpider system and the WTG components.
- Equipped with the WindSpide skidding system for controlled transport of components toward the WTG tower.
- The clamp tool is based on well-established technology from oil and gas industry, providing a fail-safe clamping solution that preserves both the structural integrity and the paint finish of the tower.
