30-Second Takeaway
STEX, based in Châteauneuf-sur-Loire, has reached a major milestone with the commissioning of France’s first Faymonville FlexMAX 4+7 self-steering combination equipped with tower adapters. Designed for demanding wind energy transport applications, the configuration delivers enhanced maneuverability, stability, and autonomous loading capability for transporting wind turbine tower sections.
First FlexMAX 4+7 with Tower Adapters in France
With the commissioning of a Faymonville FlexMAX 4+7 self-steering combination, French transport company STEX has set a new benchmark in heavy and special transport.
The configuration, equipped with tower adapters, represents a first in France and significantly expands STEX’s capabilities in supporting complex wind energy projects.
STEX is based in Châteauneuf-sur-Loire, approximately 23 kilometres east of Orléans, and specializes in demanding heavy transport operations.
Self-Steering Design Enhances Maneuverability
The FlexMAX 4+7 features a self-steering concept that enables precise maneuverability, even in tight curves and challenging topographical conditions commonly encountered on wind farm access routes.
This steering capability supports safer transport through:
Narrow rural roads
Complex intersections
Uneven and sloped terrain
The result is improved route flexibility and reduced operational risk during transport of oversized wind components.
Tower Adapters Designed for Wind Turbine Sections
The tower adapters, developed specifically for transporting wind turbine tower sections, are a key element of the configuration.
They offer a large vertical stroke of approximately 1,800 mm, allowing road irregularities to be compensated efficiently. This design also enables autonomous loading and unloading operations, reducing reliance on additional lifting equipment and improving site efficiency.
Unique Hydraulic Suspension Improves Stability
The 7-axle rear self-steering unit is equipped with a hydraulic suspension system that Faymonville describes as unique on the market.
This system delivers:
High convoy stability
Easier crossing of obstacles
Improved performance on side slopes
Enhanced operating comfort
The configuration also improves operator safety, supported by a double-redundant steering system that increases reliability during transport operations.
Supporting the Growing Wind Energy Sector
By integrating this innovative transport combination into its fleet, STEX continues to invest in meeting the growing logistical demands of renewable energy projects.
The FlexMAX 4+7 with tower adapters positions the company to handle larger components, more complex routes, and tighter delivery schedules associated with modern wind turbine installations.
Collaboration with Berroyer and Faymonville
The success of the project was supported by close collaboration with Berroyer, STEX’s technical and commercial partner, working alongside Faymonville’s product management team.
The cooperation ensured that the transport solution was precisely tailored to the operational challenges of wind energy logistics.
Through this project, Faymonville reinforces its role as a provider of complete, application-specific transport solutions, particularly for the wind energy sector.
