Transport unit, preferably for road signs

A transportation unit, particularly for road signs, comprises a rack and road signs with wheels. The rack is designed as a frame (1) with vertical posts (1a) and external crossbars (1b) located between vertical posts (1a). Pairs of shaped sections (1c) are fixed between external crossbars (1b) to define horizontal levels. At every horizontal level a stopping member (2) is provided at one side of the rack to prevent displacement of the road sign. A locking mechanism (3) is mounted at the opposite side of the rack for engagement with a socket (4) attached to a pole (5) of the road sign board (6). The upper side of the post (5) of the road sign board (6) is provided with an axis (7) with wheels (8) mounted at its both ends. The distance between wheels (8) matches the span between shaped sections (1c).
