Heavy duty Doosan DX340LCA hy-
draulic excavators, designed for
efficient operation and high produc-
tivity in demanding work environments, are
gaining popularity locally in diverse sectors,
including quarrying, mining and in heavy
construction.
“There are currently over 2 500 Doosan
machines in operation locally and we
expect to further consolidate Doosan’s
market position and soon reach the
3 000 unit mark,” says Chris Whitehead,
managing director, DISA Equipment, trading
as Doosan Construction Equipment, part
of the Capital Equipment Group (CEG) of
Invicta Holdings Limited. “Doosan makes
a substantial investment in an ongoing
development programme to upgrade
machines with advanced design features
and high performance materials, for
optimum productivity, reduced running
costs and low emissions.
“Users worldwide have the assurance that
all Doosan machines offer efficient output
power, low fuel consumption, minimal
maintenance requirements and extended
service life. Features for precise control
and enhanced operator comfort, are key to
product advancement.”
Doosan DX340LCA hydraulic excavators
have new technologies that deliver effective
control over each machine’s power and
also simplify maintenance procedures. As
a result, efficiency and machine durability
are increased, productivity is improved and
operational costs are lowered.
These high strength excavators have a
new 6-cylinder water cooled engine that is
optimised and electronically controlled to
boost production, maximise fuel efficiency
and ensure harmful emissions remain well
below the values required for Tier II engines.
Rated engine power is 185 kW (247 HP)
at 1 800 rpm and maximum torque is
114 kgf.m at 1 400 rpm. Improved cooling
performances reduce fuel consumption and
minimise noise levels in heavy duty and hot
working conditions.
New specifications of the DX340LCA series
include an increased maximum bucket size
of 2,35 m³, a side lifting capacity of 9,33 T
at 6 m reach and 3 m height and a maximum
digging force of 24,8 T. Traction has been
improved with an 8% increased drawbar pull
of 27 T. Advanced independent electronics
has increased reliability of these machines
and simplified maintenance procedures.
Doosan uses high performance materials,
combined with advanced computer assisted
design techniques, including Finite Element
Analysis (FEA) to improve design features
of every new series. All materials and
components are tested under the most
extreme conditions.
The shape of the boom has been re-designed
for improved load distribution throughout
the structure. For greater strength, material
thickness has been increased to limit
element fatigue, increase reliability and
extend component life. A highly lubricated
metal is used for the boom pivot to extend
greasing intervals to 250 hours. Cast
elements are used in the arm assembly and
reinforcement is added around the bosses
for additional strength and extended service
life. High wear resistant materials are used
for susceptible elements of the bucket,
including the blades, teeth, rear and lateral
reinforcement plates and corners of the
bucket.
All welded structures have been designed to
