iuGong, the premier Chinese construc-
tion machinery supplier, has in the last
few years adjusted its strategies to
challenge a new era in the industry. In 2014,
LiuGong launched a new brand strategy for
the global market which entailed working
together with its subsidiaries and dealers
to ensure a unified voice and create brand
consistency throughout the world.
Product quality is the key to success in the
open market and by committing consider-
able resources to machine excellence and
customer service, LiuGong has ensured it
remains competitive at all times. The com-
prehensive product range comprises 15
product lines, namely, wheel loaders, exca-
vators, bulldozers, motor graders, pavers,
cold planers, skid steers, backhoe loaders,
rollers, forklifts, truck mounted cranes,
crawler cranes, pipelayers, mining dump
trucks and concrete equipment.
LiuGong places a strong emphasis on cre-
ating value through cooperation and as
such has developed relationships with part-
ners who share the same philosophy of de-
livering technical excellence to customers
across the world. These partnerships are
focused on the machines’ core technologies
and major components. For example, the
company has key ventures with renowned
organisations such as Cummins and ZF, al-
lowing LiuGong to produce tailored, techni-
cally advanced engines, transmissions and
axles for its machines.
The introduction of the latest in heavy duty
excavators, the E-Series 970E, 70 ton model,
is a direct result of the cooperation with the
world’s best component manufacturers. The
E-Series is the latest generation of LiuGong
excavators, following in the tracks of the
successful D-Series which is renowned for
its high reliability and serviceability and now
possess even stronger power, easier control
and more safety.
The 970E’s development includes the
LiuGong’s Intelligent Power Control System
(IPC) to provide more accurate matching and
control over engine speed and main pump
flow, delivering more power, faster response
and smoother operation. Equipped with
the fuel-efficient, world-class Cummins
QSX-15 engine, the 970E meets stage II/
EPA Tier2 emission standard. The 15 litre
engine has a gross power output of 354 kW
(481 hp) @ 1 800 rpm and torque of
2 200 Nm @ 1 400 rpm. To further optimize
performance and cut fuel consumption,
the 970E features 6 selectable working
modes; power, economy, fine, lifting breaker
and attachment. A further contributor to
reducing fuel consumption is the auto-idle
speed function which automatically reduces
the engine idle to 100 rpm when all levers
are in neutral.
The business end of the 970E consists of
the boom and arm that is designed and built
with internal baffle plates, stress-relieved
for added durability and constructed from
high tensile steel plates. These structures
are designed with large cross-sectional ar-
eas and large one piece steel castings in
the boom and arm supports which ensures
long term durability and a resistance to
bending and torsional stress. The ‘H’ beam
structure used in the main platform contrib-
utes to rigidity and strength of the unit.
The 970E has a maximum digging depth
of 7 250 mm and a ground level reach
of 11 235 mm. With a bucket capacity of
4.3 cu metre, the 970E has a dump height
of 6 965 mm, adequate for loading most
mining type vehicles. The 376 kN bucket
breakout force ensures efficiency in most
material applications.
The undercarriage of the 970E construc-
tion is based on the well tried technology
of X-type high strength, box-type walking
frames. Sitting on track length of 4 750 mm
and nine track rollers, the 970E is signifi-
cantly stable in the most adverse underfoot
conditions. The track width is adjustable
to make easier to transport on a standard
lowbed.
The large, pressurised, air-conditioned cab
is well equipped providing the operator with
a wide field of vision including a height vi-
sion. The colour LCD monitor displays all
the machine information which includes all
engine functions, hydraulic oil temperature
and pressures, service interval alerts and
fault alerts.
