GIANTS ON THE ROAD
LOWER FLOOR Nooteboom is always talking to customers to find out how they can make the products even better . This is what also happened around 1995 , when the OVB trailer with its high load floor started to become outdated . Revised hydraulic steering made it possible to lower the floor height by 15 centimetres . A few years later Nooteboom introduced a new technology : pre-cambered extension sections . By making the outside beam flat and the inside beam pre-cambered , the floor will always be almost perfectly flat , in retracted as well as extended position . For this unique system Nooteboom was granted a European patent in 1999 .
GOING WITH THE WIND Just like the enormous boost in sales of the Teletrailers after ‘ Die Wende ’ in 1990 , the same happened when around 2002 demand for the transport of the longer windmill rotor blades grew explosively . The length of the rotor blades increased to 40 metres and even longer lengths were already in the planning . The double extendible Teletrailers were modified to extend two metres further and the steering ratios were adjusted . Until the emergence of wind energy Teletrailers used to often drive in retracted position , or extended by just a few metres . But for the windmill rotor blades the OVB trailers now needed to be extended to the maximum , which called for totally different steering characteristics . In particular the ratio between the turning radius angles of the various axles was changed .
EASY TO RETRACT / EXTEND To retract / extend a Teletrailer the tractor must always have enough grip . In order to make it easier to extend the trailer Nooteboom was the first trailer manufacturer to introduce the ‘ easy slide ’ system in 2003 . The moment the locking is released the suspension of the rearmost two axles loses pressure and the back of the trailer drops . As a result there is less pressure on the extension beam and all of a sudden it will be easier to extend the trailer . ‘ Easy slide ’ is a standard option on all Teletrailers with a double , triple or quadruple extendible load floor .

■ Teletrailers are a popular option for transporting concrete elements
TELESTEP QUATRO In 2007 Nooteboom introduced a Telestep version with a lower load floor for the transport of windmill rotor blades . The Telestep is based on the Teletrailer concept , but by using 17.5 ” tyres the load floor is 25 centimetres lower . At first the Telestep was only available in a triple extendible version , with 3 or 4 axles . Early in 2010 the programme was extended with a 4-axle Quatrotrailer version , with a load floor that is quadruple extendible up to a maximum length of 55 metres .
SUPER WING CARRIER Until 2010 standard triple extendible Teletrailers and Telesteps were used to transport windmill rotor blades . But the market – and the length of the blades – grew so much that in 2010 a new generation of Teletrailers for the transport of rotor blades was developed . This new TELE-PX Super Wing Carrier was first launched at the IAA in Hannover . This development was not achieved in one go . The first step was a 2-axle semi-trailer with pendle axles and a sliding axle assembly for the transport of 65-metre long rotor blades . The pendle axles guarantee a 60cm suspension stroke and the number of axles can be reduced due to the higher permissible maximum axle load . Various Teletrailers with a sliding axle assembly were built but it turned out to not always be the best possible solution . Everyday practice showed that the sliding rails that were fitted , which made it possible to retract to a shorter wheelbase even when loaded , were sufficient to provide plenty of manoeuvrability . Between 2010 and 2012 one better version after the other was tested in practice . The result was the 3-axle Super Wing Carrier ( SWC ) with a quadruple extendible load floor , able to carry rotor blades up to approx . 75 metres . Due to the lifting mechanism above the fifth wheel and the large stroke of the pendle axles , a SWC can simply lift a long blade over crash barriers or along a roundabout . In the past few years approx . 100 Super Wing Carriers have been sold . This makes Nooteboom the market leader in this segment . All the leading European companies engaged in transport for the wind industry have added this Nooteboom innovation to their fleet .
