tonnes. Annual production runs over 50 Mt. While
the two mines run many different types of haul
trucks, they have one thing in common – all of
their trucks are powered by Cummins engines,
and Cummins states that they “all depend on
Cummins service and support to deliver the
equipment availability and productivity they
need.”
The Haerwusu and Heidaigou mines operate
some of the largest haul trucks built in China,
from XEMC, NHL (both NHL supplied Terex
MT4400AC and MT5500B trucks and NHL own
brand NTE trucks both supplied by NHL from its
Baotou factory), Tolian and MCC Forterra
(including the HMTK 600A), all of which which
run alongside 44 Komatsu 930E trucks.
The large fleet of almost 300 haul trucks
enables the mines to achieve high productivity
with a very low cost of operation. Other
Cummins-powered equipment at the mines
includes large excavators, wheel loaders and drill
rigs. The total installed power of these trucks and
other Cummins-powered machines adds up to
well over 500,000 hp. This includes the mining
trucks and but an additional 40 “swing” engines.
The engine fleet includes more than 150 QSK60
engines, as well as 150 QSX15, QSK19, QST30,
K38 QSK38, K50 and QSK78 engines.
Despite severe temperatures that can fall as
low as -35°C and harsh winds making for clouds
of abrasive dust, the Cummins-powered haul
trucks, excavators, loaders and drills are able to
keep working around the clock. Cummins states:
“The huge fleet of Cummins-powered haul trucks
enables the mines to achieve high productivity at
a very low cost of operation. They deliver fuelefficient performance and a long engine life-tooverhaul, even under the challenging working
conditions at the mines.”
Li Guangyue, Cummins Zhungeer On-Site
Leader, describes how Cummins utilises tracking
and training to increase equipment uptime: “We
have a High-Horsepower Tracking System, and
the data is updated every month with info rmation
including maintenance, repair and breakdown.
We update the information to understand and
review the operating condition of every engine.
We have a series of training courses for our
customers on maintenance, covering the
knowledge that they need to know. We tell them
what they need to know so the equipment is easy
to operate, and for them to have the correct
maintenance and service.”
The on-site Cummins support team helps the
mine optimise its equipment to the specific
operating conditions at Zhungeer. The close
collaboration ensures that the full potential of
the engine is realised, to achieve enhanced
performance and maximise the life-to-overhaul.
Cummins has the swing engines on standby for
each of the engine models the mines operate.
The process to
remove the engine to
be rebuilt and install
the swing engine takes
just two days. The
performance of the
rebuilt engine must
achieve the same as
that of a new engine.
