The R 400 B series combines the load-bearing capacity of the heavy series with the lightness, ease of transport and storage characteristic of the U 300 B series. Another advantage: having the same dimensions as the U 300 B series at 300 mm, it is possible combination of these two farms to solve non-standard tasks.
