REVOLUTIONARY TRANSPORT SOLUTION

  1. 1. REVOLUTIONARY TRANSPORT SOLUTIONFOR ROTOR BLADES OF 50 TO 70 METRESNooteboom Quatro Tele-PX Super Wing CarrierRevolutionaryIt was not just a matter of increasing the vehicle length; the constructionhad to be modified too. The location of the centre of gravity of these longblades could cause the trailer to overturn. Because the blades are longerthey are also wider and even have a slightly different shape. These bladesare often manufactured to be used in areas with low wind speeds where theaerodynamics work differently. During transport the blade’s centre ofgravity is not located right above the central main beam in the middle ofthe trailer. This fact, plus the fact that these blades have been designed tocatch the wind, means that the trailers carrying these blades have to beconstructed in a way that makes them extremely torsion-stiff. And theyeven need to have a certain dead weight to ensure that they don’t overturnwhen they catch a cross wind during transport.Photography by Erik ten Have©The Tele PX Super Wing Carrier was developed because the windmills aregetting bigger all the time. The rotating blades that capture energy fromthe wind used to be 25 metres long, then 50 metres, and now they canmeasure almost 70 metres in length. In that case the existing flatbedextendible semi-trailers are no longer a practical option.Nooteboom Quatro Tele-PX Super Wing Carrier of the German haulier Hofmann.
  2. 2. The Super Wing Carrier, fitted with pendle axles, offers a much widersteering angle (60 degrees) and significantly more axle travel for extraground clearance. The pendle axles also ensure the platform remainsextremely stable, even at maximum steering angles. Another important factis that the gooseneck, which is hydraulically adjustable (80 cm heightcompensation), can be fully loaded and driven at any ride height.This Super Wing Carrier is internationally a very popular transport solutionfor rotor blades that are longer than 50 metres.Latest developmentThe latest development at Nooteboom is the Quatro TELE-PX Super WingCarrier. The Quatro Tele-PX is an important addition to the range of SuperWing Carriers that are specially designed for the transport of wind turbinerotor blades. This business is booming, especially in Germany, the Europeanmarket leader in the wind industry. During the past year the capacity ofwind turbines in Germany has increased by 26%, according to the BWE(German Wind Energy Association).Nooteboom Quatro TELE-PX SWC of the Polish specialist Trans
  3. 3. A major advantage of the Quatro Super Wing Carrier, which is based on thesuccessful MCO-PX semi low-loader, is the extremely low load floor. Thismeans that transport operators won’t have any worries about the transportheight when passing under viaducts. In countries like Germany and theNetherlands the Quatro Tele-PX can travel on the motorways and there isusually no need to map out alternative routes.Quatro Tele-PX Super Wing Carrier• Quadruple extendible• Fixed axle assembly with pendle axles• Load floor height 1090mm• Retracted length 18.7 m• Various heights load floor to gooseneck• Ground clearance highest position approx. 1.5mThe load floor is extendible in 4 steps from 17 m to just over 63 metres. Incomparison: the Triple Tele-PX is extendible in 3 steps from 18.7 to approx.60 metres. In certain European countries the shorter retracted length of theQuatro Super Wing Carrier offers important advantages as regardsexemptions.
  4. 4. Special transport reportMore information NooteboomThe hydraulically inheight adjustablegooseneck hasa heightcompensationof 80 cm.The choice of Quatro Multi-PX versus Triple Tele-PX is mainly determined bythe transport height the transport operator wishes c.q. needs to have at hisdisposal. With the arrival of bigger and bigger wind turbines, the rotorblades too are getting longer and wider. The load floor of the Quatro-PX canbe coupled to the gooseneck at various heights. Positioning the flange ofthe rotor blade behind the gooseneck creates significantly more loadingheight. In the lowest position the transport height immediately behind thegooseneck is just 760mm, which easily stays below the statutory maximumheight limit in Europe.
