The hybrid system includes a new electric swing motor, power generator,
capacitor and 104 kW diesel engine, and works by regenerating swing energy and
storing it in capacitors, which allow for fast discharge when the energy is
needed again. Needless to say, the system works best in applications where there
is a lot of slewing motion, and Komatsu says that on average the system uses
-25% less fuel than a comparable conventional machine. With all
this development potential, it should come as little surprise that Chinese
investors are eyeing the hot spots of the Middle East. China is also one of the
largest oil destination markets for the region's exporters - a fact that is
leading to new development agreements.
In May, China State Construction
Engineering Corp (CSCEC) signed an agreement with Abu Dhabi state-owned
investment company Aabar that will see it channel US$ 2 billion into real estate
projects in the emirate. The latest model from Link-Belt, a subsidiary of
Sumitomo which is active in the Americas, is the 21.7 to 23.1 tonne 210 X3. The
company says the Interim Tier 4 Isuzu engine offers 10% better fuel efficiency,
+7% more lift capacity, +3% faster cycle times and improved serviceability. As
with most other new machines this year, there is an auto idle function to cut
fuel consumption at times of inactivity.
Improvements have also been made in
bal mill operator comfort, with a +5% bigger cab and better visibility. The
large, 7-inch (178 mm) colour display is the main tool for changing the
machine's settings and this can also take a feed from the rear-view camera,
which is a standard piece of equipment. The Industrial and Commercial Bank of
China (ICBC) will provide the funding, while CSCEC will be the contractor for
the project, which includes the construction of hotels, office buildings and
high-end residential buildings in Abu Dhabi. In return, Aabar will repay ICBC
through the revenue it gets from oil trading.
Volvo's Mr Gardetun also noted
a surge in interest from Chinese manufacturers looking to target the region's
construction equipment market.
JCB meanwhile is making significant changes to
its excavator range, which includes installing its own Dieselmax 444 engine to
its 11 to 18 tonne machines. The company says one of the key advantages of
engine is that it delivers much more torque than its predecessor.
"In general
in the Middle East, we see a strong development on the crawler excavators with
the biggest demand in the 20 to 25 tonne class. We also see a growing
competition from the Chinese manufacturers on wheeled loaders and they are
increasing their share of the market," he said.
