How to safely align wind turbines
ROTALIGN and OPTALIGN set milestone in occupational safety: single-laser technology makes machine shaft alignment in gear generator wind turbines much safer.
Safety engineers around the world can breathe easy. The PRUFTECHNIK ROTALIGN and OPTALIGN technology has made aligning machine shafts, especially gear shafts, much safer. Coupled shafts that may not be rotated by hand during the alignment measurement, such as in gear generator wind turbines, can be measured absolutely safely for alignment thanks to the unique laser sensor technology.
By now, this process has advanced so much that manufacturers of wind turbines explicitly require this special technology from Bavaria because of the special HSE regulations (Health and Safety Execution).
The example gear generator wind turbine illustrates the importance of occupational safety.
