Controlled hoisting even when subject to strong forces

The nacelle is the largest and heaviest part of the wind turbine to be lifted. On or off shore, loads are huge and assembly cranes often reach their limits. It is almost impossible for cranes to control the large nacelles, and manual forces or retaining cables are no longer appropriate for the task at hand. As a result of the different configurations, the nacelle‘s centre of gravity may not always be directly below the crane hook, which can cause heavy loads to tilt.

Axzion Nacelle Spreader Beams feature an adjustable hook on the crane side which can be engaged on the load. Whether it is with hydraulic cylinder or spindle drive, and with or without an installed mains unit, Axzion Nacelle Spreader Beams are suitable for any application. The attachment points on the load can be adapted to the corresponding nacelle to correctly adjust the slings. This prevents potentially expensive damage.

Safely in control with remote control

When the spreader is being used off shore, we can measure potential frequency interference on deck and then adjust the supplied remote control accordingly. Key systems block safety-critical functions. These functions can only be used once the safely stored second key is available. It is possible to send functional messages by WiFi, so conducting an analysis via remote servicing is not a problem.
