A modular plant designed and built in South Africa by Elandsfontein-based
manufacturer Osborn is currently being installed and commissioned in
snowy Siberia. Osborn’s R11-million export order was for a full modular plant
for the Al Rosa iron ore facility in Russia. It was shipped from SA to the port
of Magadan then transported to the plant, which is situated close to Vilyuyst
in Russia’s Siberia region.
Marketing director Martin Botha says that Osborn’s robust equipment
is ideally suited for the harsh operating environment in Siberia, where tem-
peratures drop to -40oC.
The full modular plant at the Al Rosa facility offers primary and sec-
ondary crushing and screening capabilities. It features an Osborn 3042
jaw crusher, 6 x 20 triple deck screen and an Osborn 44H Gyrasphere cone
crusher. Osborn has
also supplied a 5 x
14 screen. In addition
to the modular jaw,
cone and screening
plants, Osborn offers
a full quarry process-
ing plant, by adding
the new Horizontal
Shaft Impactor modu-
lar plant to the set-up.
With the addition of Doosan’s DLA wheel loader series to the range nearly
two years ago, Doosan has significantly increased its position in the South
African wheel loader market.
“Doosan, which has been manufacturing heavy earthmoving equipment
for over 40 years, has an ongoing development programme to manufac-
ture robust machines with advanced design features and high performance
materials, for optimum productivity, reduced running costs and low emis-
sions,” says Rod Watson, MD, DISA Equipment (Pty) Limited, trading as
Doosan, part of Invicta Holdings Limited.
Operator safety, precise control and comfort are key to product advance-
ment. “Doosan earthmoving equipment - which encompasses heavy, wheel
and mini excavators, articulated dump trucks (ADTs), as well as wheel load-
ers and various attachments – has been designed to cope efficiently and
safely in Africa’s harsh operating conditions.” The DLA series, which encom-
passes four wheel loaders - DL200A, DL250A, DL300A and DL420A – have
bucket capacities between 2,0 m³ and 4,5 m³, with optimised breakout force
and machine balance.
The operating weight of these wheel loaders has been increased, with
greater tipping load capacities. These environmentally friendly machines
are driven by Doosan Tier 2 engines, which are less sensitive to fuel quality
than Tier 3 engines, yet still offer reduced fuel consumption and low exhaust
emissions.
The Doosan air to air intercooler engines offer high torque and low rpm
for improved response. High power and torque characteristics, coupled with
efficient synchronisation of the drive train with the hydraulic system, ensure
optimum productivity, even in tough operating conditions.
