Réponse rapide : RGN stands for removable gooseneck. An RGN trailer is a lowboy (lowbed) semi trailer whose gooseneck, the front section that couples to the tractor, can be detached. With the neck removed, the front of the deck becomes the loading point, so excavators, dozers and other machines drive on from the front instead of climbing rear ramps. RGNs are used for heavy, tall, long or low-clearance equipment.
RGN is short for removable gooseneck. You will also see the same trailer called a detachable gooseneck trailer, a detachable gooseneck lowbed or an Remorque surbaissée RGN. All of these names describe one design: a low-deck semi trailer with a gooseneck that separates from the deck for front loading.
How the neck is lifted and detached depends on the build. Some RGNs use hydraulics powered by the tractor; others carry their own power unit. On the CHENLU Remorque à col de cygne amovible de 80 tonnes, a 12 kW diesel engine drives the hydraulics.
| Part | What it does |
|---|---|
| Col de cygne amovible | Couples to the tractor’s fifth wheel; detaches to open the front of the deck |
| Low deck (well) | Carries the machine as low as possible to keep the loaded height down |
| Rear deck and axle group | Sits over the axles and carries the rear of the load |
| Lifting system | Raises and lowers the deck front when the neck is detached or re-coupled |
There is no single standard size. Deck length, width and height are set by the machines you haul and the road rules where you operate. These are the layouts of CHENLU RGN models:
| Modèle | Longueur totale | Largeur | Plateau surbaissé | Hauteur du pont | Essieux |
|---|---|---|---|---|---|
| 3 Axle RGN | 15,000 mm (16,495 mm longer build) | 2,600 mm | 6,000 mm (7,500 mm longer build) | 850 mm | 3 |
| 80 Ton RGN | 16,000 mm | 3,000 mm | To order | To order | 3 or 4 |
| 100 Ton 4 Axle RGN | 18,000 mm | 3,500 mm (4,000 mm with extensions) | 7,700 mm level | 900 mm | 4 |
A deck wider than your country’s standard road width usually needs an oversize permit. Check width, height and axle-load limits for your route before you order.
| RGN (removable gooseneck) | Porte-engin surbaissé à col de cygne fixe | Plateforme à paliers | |
|---|---|---|---|
| Chargement | From the front, neck detached | From the rear over ramps | From the rear or by crane |
| Hauteur du pont | Le plus bas | Low | Higher than a lowboy |
| Meilleur pour | Heavy, tall or low-clearance machines | Machines that climb ramps safely | Lighter equipment and general cargo |
| Cost and upkeep | La plus élevée | Inférieur | Le plus bas |

Axle count follows the machine weight and the axle-load limits on your route, not the trailer name. As a starting point, mid-weight excavators and loaders often travel on a RGN à 3 essieux, while large excavators and mining machines need four axles or more, such as the RGN 100 tonnes à 4 essieux. The final rating also depends on where the machine sits on the deck and on the tractor.
Removable gooseneck. It is a lowboy trailer whose front gooseneck detaches so equipment can be loaded from the front.
An RGN is a type of lowboy. “Lowboy” on its own usually means a fixed gooseneck lowboy that loads from the rear.
Yes. Detachable gooseneck, removable gooseneck and RGN describe the same design.
It depends on the axle count, the structure and local axle limits. CHENLU RGN models range from 3 axle builds rated per order to a 100 ton target payload on four axles.
Choose an RGN when your machines are long, have low ground clearance or cannot climb rear ramps safely, or when the loading site has no room behind the trailer.
