UNDERGROUND LOAD & HAUL
The newly revised Paus PFL 8 LHD with 1.5 t
payload
manoeuvrable articulated vehicles have an
optimised turning radius. “The smallest loader
PFL 8 with approximately 1,950 mm masters even
90° curves in gallery widths of only 2.2 m
excellently.” In detail, the Paus loaders have the
following turning radii: PFL 10: 2,700 mm, PFL 20:
2,450 mm and the PFL 30: 2,750 mm.
The articulated oscillating axle steering (on
the PFL 20 and 30) and the articulated
oscillating steering (on the PFL 8 and 10)
compensate for any unevenness in the road and
thus offer more driving comfort. “All controls can
be reached from the driver's seat and are easy
to see. The lateral seat arrangement provides
the driver with a good overview when driving
forwards and backwards. The operator's
platform is equipped with two joysticks - a
multifunction joystick for the direction of travel
and gear shifting, and a joystick for the working
hydraulics. Engine components such as filters or
oil dipsticks are easy to change or check. One
less worry: hard-to-reach areas are
automatically lubricated by the optional central
lubrication system. The clearly laid hydraulics
and electrics are easy to maintain via flaps in the
operator's platform. Countersunk screws are
installed in many places to protect them from
damage during rough working conditions.
Backlash-free, robustly designed spherical plain
bearings in the articulated steering area are just
as easy to lubricate.”
Paus says the loaders are characterised by
their robustness, efficient
hydrostatic/hydrodynamic drive systems and
current exhaust emission levels. While the PFL 8
and 10 have a hydrostatic drive, the PFL 20 and
30 are equipped with a hydrodynamic drive with
“full power shift”. PFL 8 to 30 are delivered with
Deutz engines, PFL 10 and 20 are also available
with Cummins engines. Various exhaust emission
standards, TIER 4f (EURO Stage V ready) and
TIER 3a are thus met.
The PFL 8 and PFL 20 are also available in a
battery-operated version for emission-sensitive
underground mining or sites with low fresh air
supply. Mines with 400-1,000 V voltage and 50 or
60 Hz frequency can fall back on the loader
variant PFL 15E with tethered power supply.
Equipped with an active drum drive for orderly
winding. This protects the cable and increases
the service life.
“The proven hydrostatic drives complement
the electric drive perfectly with their stepless
transmission. The combination of the drives and
an intelligent control system minimize power
losses and sustainably reduce energy
consumption. Brake and tyre wear are also
reduced.”
The operator's platform complies with
ROPS/FOPS requirements. A fire extinguishing
system, which can be triggered from several
locations, is part of the basic configuration. The
very high thicknesses of the metal plates on the
one hand protect the driver, on the other hand
the robust construction stands for the high
availability of the articulated vehicles. In
addition, the vehicles have additional underbody
and impact protection. The Posi-Stop brake
enables safe manoeuvring of the loader when the
vehicle is moving downwards when loaded. If
necessary, the exhaust flap brake or the retarder
with lock-up clutch can be used as a continuous
brake. A CE declaration of conformity is available
for all Paus loaders.
Aramine partners with ARMZ on
battery
Underground vehicle specialist Aramine says it
has signed a partnership agreement with Russia
uranium producer, ARMZ, for the assembly of its
L140B battery-powered miniLoader. The pact was
signed by ARMZ Uranium Holdings’ Director
General, Vladimir Verkhovtsev, and Aramine
Presidents, Marc Melkonian and Christophe
Melkonian, during the 23rd International Mining
World Russia Exhibition, in Moscow.
