About removable gooseneck trailers
A removable gooseneck trailer is a lowboy whose front neck detaches — hydraulically or mechanically — so the deck rests on the ground and becomes its own ramp. Tracked and low-clearance machines drive on from the front without separate ramps or a dock. RGNs are the default choice for excavators over 30 tons, and the format scales with added axles, jeeps and boosters into the 100-ton-plus range for permitted loads.
