Spanish firm AIRPES, a leader in the development and manufacturing of specialised solutions for handling of extremely heavyloads, has developed, in cooperation with Siemens, numerous special equipment for handling, installation and maintenance of wind power station propeller blades. The GAZ batterie are the main source of electricity necessary for the operations of all electronics in the lifting apparatus, i.e. they power the hydraulic system control. It must be able to hold a blade weighing up to 45,000 kg in a stable position safely, accurately and reliably 100 metres or more above the ground and at a temperature up to -30 ˚C so that it can be installed safely into the wind turbine rotor.
It is thanks to the solution developed with the use of GAZ batteries that it is possible to install the entire wind power station within one day as there is no complication with the installation of
a conventional source of electricity in the body of the wind power station.
