NEW EQUIPMENT NEWS
New Doosan tracked excavator series welcomed in SA
the touch of a button, to control operating
modes for comfortable and productive
operation,” says Holton.
Doosan’s recently launched
D-Ecopower+ intelligent hydraulic system
delivers best in-class productivity. The
new electronic main pump accurately
calculates the amount of pump flow
required for each actuator, ensuring faster
operation and optimum productivity, also
preventing unnecessary fuel loss.
Fuel saving technologies include
Smart Power Control (SPC) and a highly-
efficient cooling system. The SPC allows
the machine to provide optimised control
for engine speed and torque, based on
different workloads, therefore reducing
unnecessary fuel consumption. This is
enhanced by a larger radiator for greater
capacity and faster cooling speeds.
On-site safety and improved operator
comfort are an important focus in the
design of this new series. New LED work
lights enable safe operation after dark and
an Around View Monitor (AVM) provides
a clear 360° view for the operator from
inside the cabin. An anti-hose burst
protection system prevents secondary
accidents resulting from a boom / arm-
down that may be caused by a sudden
hose burst. A new air compressor in the
cabin improves comfort for the operator,
by keeping the air clean.
A heavy-duty two-stage dust cleaner
prevents dust and contaminated particles
from causing damage to components
together with standard Auto Grease
System (AGS) that significantly reduces
maintenance time. An Electric Fuel
Transfer Pump (ETP) is switched on to
refill the machine easily after inspection
or repair.
For added convenience, the water
separator, pre-fuel filter and main filter
are grouped together to minimise
maintenance time while extending engine
life and preventing machine failures.
Machine inspection and maintenance is
simplified and made safer by having one
access point and a wider catwalk.
A wide range of Doosan attachments
for versatile operation, include hydraulic
breakers and various buckets for specific
tasks. The X-Class extreme mining bucket
is used for high-strength and abrasion
resistance materials and the S Class
severe-duty bucket is recommended for
mass excavation in high-density difficult
mining and quarrying applications.
These excavators can also be
adapted for special applications, by
adding attachments for unusually long
digging reaches; orange grapples and
clamshell buckets for material handlers;
rotating crushers and multi-processors
for high-reach demolition tasks; and
straight or V-shape shovel buckets for
front shovels tasks.
The Doosan team offers a technical
advisory, maintenance and support and
spare parts service through its national
branch and distributor network.
Doosan’s new DX800LC-5B tracked
excavator series, which was launched
in early in 2018 has been well received
by the local market, particularly the
mining sector.
“The new DX800LC-5B tracked
excavator – with an operating weight of
78 500kgs – is currently the largest
machine in the Doosan range of
construction and mining equipment. This
robust machine has been designed for
high productivity, fuel efficiency, minimal
downtime and greater safety in harsh
operating conditions,” says Darrel Holton,
managing director, DISA Equipment
(Pty) Ltd T/A Doosan, part of the Capital
Equipment Group (CEG) of Invicta
Holdings Limited.
Holton adds that the DX800LC-5B has
a redesigned structure with a heavy-duty
front and improved undercarriage. It is
fitted with many customised components
that ensure continuous operation in
arduous environments with minimum to
no downtime.
“Our customers are also impressed
with the fuel-efficiency of this machine.
The new DX800LC-5B engine, with
enhanced power and durability, offers
cost-efficient performance and low
maintenance requirements. In addition,
our customers note the convenience of
being able to easily select the appropriate
operating mode for various work
environments. The boom / swing priority
control facility enables the operator, at
