Crawler Excavators
Liebherr tunnel excavators are special machines
which can be used in all conventional types of
tunnelling applications: In order to create cross-
tunnels after tunnel drilling machines have been
used, for secondary profiling when explosives are
being used and, of course, for direct excavator tunneling.
Particular features of these machines are their economic
operation, high performance, and reliability.
