They are used for transporting steel or concrete beams and are suitable for bridge sections or wind turbines. DOLL supplies three-axle, four-axle and five-axle self-steering trailers, depending on payload requirements with trailer axles offered in combination with two- or three-axle dollies.
- 3 to 5 axles

- Maximum possible payload up to 85 t, depending on vehicle combination
- Maximum possible length of the transported cargo up to 80 m
