The Wimmer tunnel excavator series consisting of Blue Badger, eBadger and miniBadger was specially designed for smaller tunnel cross sections. For all applications for which the Blue Badger is too small, there will be another tunnel boring machine in the future: the yellowFOX.
The yellowFOX will be usable for working heights from 4.2 m. The Badger series is ideal for tunnel cross sections from 3.5 m.
