Vehicle with ejection unit

The vehicle has side wall elements that are constructed in two portions with an upper and a lower side wall portions (60,62,64). One of the side wall portions is movable or detachable to the other side wall portion, so that a transportation space (34) is opened towards a side wall opening (66). The transportation space is bounded by a wall (24), where an exhaust unit (50) is inserted in an opening in the wall, and is movable between a retracted and an extended position. A loading floor in a transport chamber (34) is adjustable in height between a loading position and an accommodation position.
