150 m to 300 m, with nine hours of
production time each day.
Weighing 4.7 mt unloaded, the
L130D loader is designed for use in tun-
nels measuring a minimum of 1.8-m
wide and 2.3-m high. Aramine pro-
vides a choice of three diesel engines
for these machines; a 43-kW Perkins
water-cooled unit, or a 50-kW air-cooled
Deutz, with a 40-kW Deutz engine avail-
able for high-altitude operations up to
4,000 m. The machine's ventilation
requirement is 86 m
3
/minute.
The operator's position is side-
mounted, with a ROPS/FOPS canopy
above. Hydrostatic drive provides tram-
ming speeds of up to 8.5 km/h, with
the machine offering a production
capacity of between 30 mt/h and
40 mt/h over a 100-m haul distance,
down to 15 mt/h at 300 m.
As all of the mines at Priargunsky are
shaft-accessed, the Aramine loaders
had to be disassembled, lowered
in pieces then reassembled under-
ground. Today, all of the maintenance is
carried out in underground workshops.
According to Alexei Nevskiy, asset
management director for ARMZ, the L-
130s have shown good reliability since
they were commissioned, not only
because of their build quality but also
reflecting the after-sales support pro-
vided by Aramine's service engineers.

Aramine claims that its L130D is more powerful and productive than competitive LHDs working at Priargunsky.
