A freight vehicle has a frame defining a support surface for the goods to be transported, a plurality of rubberized wheel assemblies with suspensions, the height of which can be adjusted to shift the support surface between a lowered loading position and a raised transport position, and a driver's cab arranged beneath said support surface; the cab being coupled to, and overhanging, the frame by means of an articulated quadrilateral transmission unit and being shifted by pneumatic actuators configured to vertically move the whole cab in relation to the support surface between two extreme end positions, one approaching the support surface and one spaced apart from said support surface, and to arrange the cab in a cushioned intermediate position for the transport of the goods.
