Navassy builds the first autoization system for the Nabralift 2.0 tower, which can install towers up to 200 meters.
Navassy, ??made up of Navarra Nabrawind, Tetrace and Comansa, will manufacture between 6 and 8 automated systems in the coming years in line with Nabralift’s order book.
Navassy has completed the manufacture of the first automation system for the Nabralift 2.0 tower, developed by Nabrawind, and will shortly be moving 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.
The Comansa company, which together with Tetrace and Nabrawind make up Navassy, ??has been in charge of the manufacture of the new self-lifting system, whose patented design incorporates numerous evolutions compared to the predecessor model, especially with regard to reduction of time, costs and necessary surface. associated with field assembly.
This milestone corroborates the industrial strength that Nabrawind has deployed to successfully address its market entry, after having generated a network of suppliers that manufacture its components and logistics capabilities to transport said components to their destination.
After this first unit, Navassy will manufacture between 6 and 8 automated systems in the next six years, in line with Nabralift’s order book. Comansa will once again be in charge of the manufacture of the following automated systems through its facilities in Spain and China.
Characteristics of the authorization system
The automated system, which will be operated in the field by Tetrace, has dimensions of 25 meters in height with a distance between its masts of 20 meters. However, the autoizado system stands out for its reduced dimensions compared to the crawler cranes that are usually used to install wind turbines.
Specifically, the logistics related to the autoizado system includes a total of 14 standard trucks. On the contrary, a crawler crane capable of installing 140-meter towers has complicated logistics and requires more than 40 trucks for transport, several of them of special dimensions.
In the same way, the assembly times of the authorization system are very efficient. The entire system is installed in three days and can perform two lifts a day or, in other words, the lifting of a tower between 160 and 170 meters high is completed in three days. Finally, moving from one position to another within the wind farm can be done in just one day.
