A sliding counterweight ensures stability as the blade is raised or lowered

The record breaking blade has an overall length of 62 metres and weighs 13.4 tonnes, making it a challenge to transport, especially for the ‘last mile’ to turbine sites.

The company has been trialling a second generation of the Scheuele blade adapter and transporter. Not only can the blade be raised to an angle of up to 70 degrees in order to negotiate tight bends in wooded areas, but the blade can also be rotated, in order to find the position with the least wind resistance. A sensor warns when the rotation creates a situation that exceeds the maximum allowable resistance/wind speed.

The quick release plate connects to the adpator in around five minutes according to the manufacturer

The blade is bolted to a quick release plate that can be used on regular trailers as well as the 126SP, allowing a normal truck and trailer to move the blade over greater distances, while making it easy to shift over to the Inter Combi SP for any challenging bends, usually limited to the last few miles of a move.

The blade is installed and ready to go

The testing appears to have confirmed the practicality of the adapter with the longer blades and is now ready for service.
