Avanti Wind Systems presents two newly developed Service Lifts for wind turbines at the EWEA Convention in Copenhagen from 16th-19th April 2012.
The new Pegasus is a Rack and Pinion Service Lift guided by the ladder system in the wind turbine. The lift is pulled up and down through pinions geared by motors on the lift and a rack welded to the ladder system. The new Rack and Pinion Lift is developed by Avanti due to different internals design and tower dimensions, especially adapted for concrete towers of WTG.
The other newly designed Service Lift – Dolphin – is guided by wires. It has a sliding door that can be divided in an upper and a bottom part and the lift can be equipped with windows.
Both new Service Lifts have space for two technicians and their tools. And like the other Service Lifts from Avanti Wind System, the new Pegasus and Dolphin Service Lifts can be put into service already during construction and commissioning of the turbine with the benefit that the technicians making the final installations in the turbine do not have to climb up and down the ladders.
The lifts cannot run if the door is open, but when the lifts are brought to a standstill and the technician is secured on his hook, inspection and repair can be performed from the lift.
Avanti Wind Systems has produced more than 16.000 Service Lifts for wind turbines all over the world, which is more than half of those installed.
All Service Lifts from Avanti Wind Systems are obviously approved according to relevant standards worldwide. They are manufactured with high quality components and seawater resistant aluminum and can be used both onshore and offshore.
