technologically advanced in
the industry
Fully robotized
11 Jumbos with 4 booms (3 drilling rigs
and a lift basket), fully robotized and able
to achieve headings up to 5.5 m. And
capable of covering sections between 24
and 196 m2. These Jumbos, from more
than 200 kW power, are equipped with an
automatic drilling and positioning system,
ruled from a central computer to be
installed in the cabin. The positioning and
guidance system consists in a laser device,
which combined with the sensors network
of the sliders makes it he most accurate
tunneling system.

The adaptability of the TBM technology of Cavosa,
without sacrificing the highest quality standards,
results in unalike constructions such as the
excavation of tunnels for the high-speed train, for
channeling water, for highways passing or for the
subway network.
