Lowbed trailer is a professional heavy-duty semi-trailer for oversized, tall and overweight cargo transport, also named low loader/lowboy trailer. It adopts step-type drop-deck design (raised gooseneck + sunken main loading deck), greatly lowering cargo center of gravity. Widely used to haul excavators, bulldozers, loaders, drilling rigs and mining equipment across Africa, Southeast Asia and Middle East infrastructure & mining projects, customizable for different axle quantities and load demands.
