RUD has presented neXera, an electric hoist developed for maintenance operations on wind turbines. The system is designed for lifting applications at hub heights of up to 200 metres, for both onshore and offshore turbines. The hoist supports loads of up to 800 kg and operates at variable lifting speeds between 24 and 80 metres per minute.
At the centre of the system is the patented X-Drive chain drive, which enables higher chain speeds while aiming to limit chain wear. The design is intended to reduce the time required to transport tools and materials during turbine servicing, thereby lowering turbine downtime.
The RUD neXera 800 can lift an 800 kg load to a height of 200 metres in around eight minutes, with higher speeds possible when operating without a load. The hoist is also intended for frequent empty lifting cycles, which are common during maintenance work.
Safety features include an integrated incremental encoder that allows precise setting of upper and lower hook positions and records shaft revolutions for repeatable positioning. The system can be fitted with either a load hook or a load eye, depending on operational requirements.
The hoist has a modular design intended to simplify servicing and replacement of components. Control elements are housed separately from the lifting unit to reduce exposure to vibration. Operating data can be recorded and stored in the frequency converter to support inspection and maintenance requirements in line with DIN EN 14492-2.
