Spain’s Nabrawind has developed a system for installing very tall wind turbine towers without transporting a massive crawler crane to the site. Its Nabralift design combines a tubular upper tower with a three-legged steel support structure. Hydraulic equipment lifts the assembled turbine as modular tower sections are added underneath it near ground level. The lifting frame can then be reused at another site.
The approach could ease construction and transport challenges, particularly at remote locations where specialist cranes are costly to bring in and wind can disrupt conventional lifting. Nabrawind says its design uses about 20% less tower steel than comparable conventional tubular towers and can cut foundation concrete by as much as 80%, depending on the design and site. These are company-reported figures, not savings established across all projects.
In September 2026, UL Solutions issued type certification for an Envision 7.8-megawatt turbine installed on a 188-meter Nabrawind tower. Fortescue is using 17 of these tower configurations at its 133-megawatt Nullagine wind project in Western Australia’s Pilbara region, where construction is underway. Nabrawind has also erected a 160-meter prototype in Spain and supplied smaller commercial towers in Morocco and France.
The Nullagine project will test the system in a significant deployment, but its ownership structure differs from a typical independent wind development. Fortescue acquired Nabrawind in September 2025 and is building the project to supply its own mining operations. That provides an industrial customer with an incentive to support the technology, but does not show whether unrelated developers can finance and maintain it under standard third-party arrangements.
Nabralift also introduces a procurement concern. Developers can buy conventional tubular towers from multiple qualified manufacturers and compete some construction work among experienced contractors. With Nabralift, the core tower system, specialist lifting expertise and related support come from one supplier. A turbine-and-tower type certificate offers technical assurance for the certified configuration, but does not settle questions about delivery commitments, warranties, maintenance, replacement parts or remedies if the supplier’s capacity or priorities change.
Those issues matter for wind farms expected to operate for 25 years or more, especially when there is no qualified alternative provider for the same system. Nabrawind’s next commercial test will be whether an independently developed and financed large wind farm accepts the technology on workable terms. Qualified installation partners, long-term service arrangements and broader supply capacity could help developers assess its engineering benefits alongside the risks of relying on a proprietary system.
