This 3‑axle Removable Gooseneck (RGN) lowboy semi‑trailer is heavy‑duty transport solution for over‑size, overweight cargo. It is widely used to haul excavators, bulldozers, cranes, road rollers and other large‑scale construction equipment.
The hydraulic detachable gooseneck can be fully separated from the main deck. Tractor unit can drive away, so heavy machinery can drive directly onto the flat deck from front side, without long rear loading ramps.
Constructed with high‑strength Q355 steel box‑section main beam, the trailer features outstanding torsion resistance and heavy‑load capacity. Ultra‑low deck design reduces overall center of gravity, guarantees stable and safe transportation for tall over‑height loads.
Equipped with robust 3‑axle heavy‑duty leaf‑spring suspension, heavy‑load tires and reliable locking mechanism for gooseneck connection. Hydraulic system enables easy and fast gooseneck disassembly.
Full blasting and multi‑layer anti‑corrosion painting ensures long service life under harsh road conditions.
