Navassy manufactures the first Self-erecting System for the Nabralift 2.0 tower, capable of installing towers up to 200 meters high
Navassy, made up by Nabrawind, Tetrace and Comansa, will manufacture between 6 and 8 Self-erecting Systems over the next years in order to meet Nabralift’s order backlog
Navassy has accomplished the manufacture of the first Self-erecting System for the Nabralift 2.0 tower, developed by Nabrawind, and will soon be transported to Morocco, specifically to the city of Oualidia, where it will complete the installation of a Nabralift HH144 tower in a wind farm owned by the French renewable energy company Innovent.
Comansa, Navassy’s partner along Tetrace and Nabrawind, has manufactured the new Self-erecting System. This new patented designed includes several advantages compared to its predecessor. In consequence, this new system shortens the installation timing and reduces the assembly space requirements while reducing the cost of the maneuver.
The manufacturing of the first Self-erecting System reaffirms the industrial strength that Nabrawind has deployed to successfully address its entry market. In the past year the Spanish company has developed a strong supplier’s network that manufacture its components and logistics capabilities.
This Self-erecting System is the first unit of a fleet which will deploy 6 of these systems during the following six years in line with Nabralift’s order backlog. Comansa will be again responsible for the manufacture of the following systems through its facilities in Spain and China.
Features of the Self-erecting System
The Self-erecting System, which will be operated by Tetrace, is 25 meters high with a mast spacing of 20 meters. However, the Self-erecting System stands out for its small dimensions compared to the crawler cranes commonly used to install wind turbines.
Specifically, the logistics for the Self-erecting System involve a total of 14 standard trucks. On the contrary, the logistics of crawler crane capable of installing 140-meter towers requires more than 40 trucks, several of them of special dimensions.
Likewise, the assembly times of the Self-erection System are very efficient. The entire system is installed in three days and performs two lifts per day or, in other words, the lifting of a tower between 160 and 170 meters high is completed in just three days. Finally, the transfer from one position to another within the wind farm can be done in just one day.
