A removable gooseneck trailer is a type of trailer that has features of a semi-trailer combined with a double-level drop system.  These trailers are more versatile than flatbed trailers or semi-trailers, as they can haul and carry equipment of up to 12 feet in height and between 40,000 and 80,000 pounds.  Depending on the style of removable gooseneck trailer chosen, the deck height can be adjusted to drop at the gooseneck or before reaching the wheels.

Removable gooseneck semi trailers are often utilized for transporting heavy machinery, such as bulldozers, excavators, backhoe loaders, and other types of heavy equipment.  Items that do not fit onto a flatbed trailer or a single-drop deck trailer can typically be hauled via a lowboy trailer.
