About Us

Heritage, engineering, and the team behind Femmerr trailers.

Femmerr Trailer manufactures heavy-duty lowbed trailers engineered for oversized cargo, heavy machinery, and industrial equipment transport. Available in 3-axle, 4-axle, 5-axle, 6-axle, and fully custom configurations, each trailer is built using S355J2+N high-strength structural steel (355 MPa yield strength) and Strenx 700E ultra-high-strength steel (700 MPa), reducing overall weight by up to 30% while maintaining maximum load-bearing integrity. All chassis and main beams are precision-welded under controlled factory conditions to ensure consistent structural performance across demanding transport operations.

Femmerr hydraulic systems feature multi-axle independent steering with proportional valve control, hydraulic ramp deployment, and adjustable air suspension rated for payloads exceeding 100 tons. The modular deck system supports extendable, telescopic, and drop-deck configurations for transporting excavators, cranes, transformers, wind turbine components, and other oversized industrial loads. Every trailer complies with EN 12195 load securing standards, EC Type Approval, and ADR regulations for international heavy haulage across Europe, the Middle East, Africa, and Central Asia.

As a vertically integrated manufacturer, Femmerr controls the full production cycle, from laser cutting and CNC machining to robotic welding, surface treatment, and final assembly, at its production facility in Turkey. The company offers direct-to-fleet sales, custom engineering consultations, and after-sales technical support. Femmerr is a brand of STU Trailers, an established group with over 15 years of expertise in special-purpose trailer design and manufacturing for professional logistics operators worldwide.
