Folding gooseneck trailer is a kind of front-loading trailer, different from the RGN trailer, you can load the trailer from the front of the lowbed trailer(could be flatbed trailer) but no need to dismantle the gooseneck from the trailer body. It is widely used for transporting construction machines no matter they are with tires of crawlers.
Lowbed trailer with a foldable neck makes you move construction machines easily even without crane’s lifting. When unhooking from the prime mover, the semi trailer’s neck could be folded to ground as a shallow slope for crawler crane and other machines to drive on. It is one of the popular front-loading trailers, another one is detachable gooseneck trailer.
Conventional lowboy trailer normally equipped with hydraulic ramps at the rear side of the trailer, which can help with the loading of the cargo machines. Because of the height of the trailer, the ramps are steep. If the cargo is too heavy, it would increase risks during loading by the hydraulic ramps.
To resolve above problems happened with rear loading method, we have two types of front-loading trailer to handle them.
The gooseneck is a design with a hydraulic folding structure. When the structure folded, it’s a gooseneck to connect the trailer with the prime mover. When it unfolded, it’s will touch the ground as a shallow slope for cargos loading. Compare to rear ramps, it’s shallow and stable, could effective solutions for cargo loading.
