Doosan reports that it has significantly
increased its position in the South African
wheel loader market following the launch
of its DLA wheel loader series in the local
market some three years ago.
The DLA series comprises five wheel
loaders – DL200A, DL250A, DL300A, DL420A
and DL 550A – with bucket capacities
between 2 and 4,5 m³. The machines are
powered by Doosan Tier 2 engines, said
to be less sensitive to fuel quality than
Tier 3 engines, yet still offer reduced fuel
consumption and low exhaust emissions.
Doosan’s DLA Series machines come
with a four-gear transmission and clutch
cut off via a brake pedal. The transmission
has three modes of operation – manual,
automatic (automatic shift for all gears)
and semi-automatic (automatic with a
‘kick down’ for first gear). A large capacity
transmission oil cooler ensures stable op-
eration of the transmission.
The DL300A and DL420A units, which are
widely used in local conditions, have the
flexibility to handle diverse applications,
including the loading and transporting of
granular materials, as well as bulk loads. The
DL300A wheel loader is powered by an 8
ℓ
Doosan DE08TIS engine delivering 156 kW
at 2 100 rpm, while the DL420A comes with
a 11
ℓ
Doosan DE12TIS engine producing
210 kW at 2 100 rpm.
The high strength drawbar pull at the
wheels is reinforced by limited slip ZF
differentials as standard equipment.
This automatically ensures maximum
tractive effort and easy driving over soft,
muddy ground. This feature also reduces
the risk of skidding and prevents exces-
sive tyre wear.
Metal reinforced brake discs are
integrated into the planetary reduction
gears in the hubs where the rotation speed
is lower. As a result, discs are exposed
to lower rpm and heat generation is
reduced. This ensures improved machine
stability, extended hours of operation
and reduced maintenance requirements.
For user convenience, brake disc wear
can be measured without disassembling
the hub.

DLA range ups Doosan’s SA share
The Doosan DLA Series is ideal
for diverse applications including
the loading and transporting of
granular materials, as well as
bulk loads.
