Crawler Loaders
Thanks to their high break-out forces,
excellent maneuverability, and robust
equipment, Liebherr crawler loaders
are the ideal machines for tunnel con-
struction. Depending on the operational specifications,
they can be configured with individual options to tailor
the machines to particular applications and conditions.
A high-performance air conditioning system matched to
a pressurized cab helps create a comfortable working
environment. The Liebherr particle filter is also optionally
available to provide cleaner air in the tunnel.
Wheel Loaders
Liebherr tunnel wheel loaders are spe-
cially designed for use in tunnel appli-
cations. The advantages of the wheel
loader´s hydrostatic drive are proven in
difficult tunneling applications. The advantages are: re-
duced fuel consumption through improved utilization of
the engine´s output, minimal brake wear through the hy-
drostatic braking effect of the drive and reduced tire wear
thanks to stepless adjustment of the tractive force in line
with what is required. Also, the Liebherr particle filter re-
duces particulate emissions by 99 %.
