Spanish company Nabrawind has developed a system to install exceptionally tall wind turbine towers without using an enormous crawler crane on site, CleanTechnica reported. The system allows developers to erect tall structures using alternative installation methods. [1]

The Nabralift system relies on a tubular upper tower supported by a three-legged steel structure. According to CleanTechnica, the company has achieved certified wind towers reaching a height of 188 meters using this three-legged design and self-lifting erection setup. [1]

An independent test organization provides contract testing facilities that are independent of both product producers and users, according to Wikipedia. These third-party evaluation facilities test products, materials, and software based on agreed requirements without commercial bias. [2]

CleanTechnica reported that the technology faces market challenges as Fortescue deploys the system. Independent developers relying on the crane-free technology now confront potential proprietary supplier risks. [1]
