New Faymonville wind tower adapter mounted on 4+7 dolly trailer

Special trailer and semi-trailer manufacturer Faymonville has launched a wind tower adapter with free rotation device mounted on a 4+7 dolly trailer that can be used for transporting large wind turbine towers weighing up to 100 tonnes on winding roads. The new model fills the last gap in its existing range, says Faymonville.

The vehicle is based at the front on a four-axle dolly with air suspension – optionally with 17.5” or 22.5” tyres – which can be configured for 6x4 and 8x4 or 8x4 and 10x4 tractor units. “For the first time ever, 10x4 machines can take on such missions,” says Faymonville product manager Rainer Noe. “The different base variants and tyre options make the concept extremely interesting for the user.”

Two installed tower adapters facilitate connection to the tower segments in three-point or four-point clamps without an additional frame. In the basic version, the components are conceived for internal diameters from 2,650 to 5,400 millimetres. “And an extension to 6,300 millimetres is available if even larger tower segments need to be moved,” says Noe, describing the solution for possible XXL versions.

The two adapters are designed for maximum flexibility, as segments with an external flange can also be accommodated. Even the transport of various machine houses is possible with this system. The vertical stroke of 1,600 millimetres facilitates passing over high obstacles along the route, such as roundabouts, crash barriers or road boundaries.

“We are the only supplier on the market with a hydraulic suspension,” says Noe. “This principle is used to raise or lower the self-steering trailer on one side, thereby increasing the stability of the convoy considerably in critical passages.

“The steering system has four steering cylinders for the front steering and four for the rear steering. For further optimisation of the safety aspect, the vehicle width is set to 2,750 millimetres.” Hydraulic and mechanical locking systems prevent inadvertent lowering or retraction of the adapter. The general handling is intuitive and simple. When handling the adapter, the user is always in a safe area due to the standard remote controls and has a perfect overview when loading and unloading.
