Doosan’s newest generation hydraulic excavators – the heavy
duty DX225LCA series – has been designed for greater operator
comfort, improved fuel efficiency, enhanced productivity and
minimal maintenance requirements.
“There are currently 360 20T Doosan DX excavators in operation
in the local market and we expect the improved DX225LCA series
to further consolidate Doosan’s position as a leading supplier in this
size class of equipment,” says Chris Whitehead, national sales man-
ager, DISA Equipment (Pty) Limited, trading as Doosan, part of the
Capital Equipment Group (CEG) of Invicta Holdings Limited. “These
robust excavators, which are now available in Southern Africa,
are fitted with special features to ensure optimum efficiency and
extended service life in harsh local operating conditions.
“Design features for the Africanmarket include aTier II mechan-
ical engine for reduced operating costs, a heavy duty boom and
arm, as well as standard hydraulic piping for hammer applications.
These machines also have an improved H Class bucket and are
supported by Doosan with a two-year/ 4 000-hour warranty.
“This series features a range of new technologies that deliver
effective control over the machine’s power and also simplify main-
tenance procedures. As a result, efficiency and machine durability
are increased, productivity is improved and operational costs are
lowered,”Whitehead adds.
High performance materials, combined with advanced com-
puter assisted design techniques, including Finite Element Analysis
(FEA) are used by Doosan to create robust structures and all materi-
als and components are tested under the most extreme conditions.
The 21,5 t operating weight of these excavators is enhanced
by new specifications that include a 0,92 m³ bucket capacity, a
digging depth of 5 755 mm, a digging reach of 8 950 mm and a
digging height of 9 750 mm. The engine rated power is 110 kW
(148 HP) at 1 900 rpm.
