COMPONENTS
Building for the future
Produced at its factory in Wuxi, China, the
transmission has been developed to meet enhanced
emissions ratings and is said to help deliver 25%
fuel-saving through its advanced design.
Engines
In terms of engine development, Bauma
China saw manufacturers including
Cummins, introduce products devised
for both regional and global markets
that are compliant with emissions
legislation.
The company’s latest two models
have promised what it has claimed
as potential fuel savings of
between 15% and 20% on
previousmodels.
TheQSB76.7 litre andQSF3.8
litre units have drawn from an existing
line of engines specially adapted for the
Asianmarket. Both engines complywith
China’s soon-to-be introduced Stage III
emissions regulations and are expected
to have broad application across the
constructionmarket.
The 6-cylinder 6.7 litre engine is aimed
primarily for excavators between 20-30
tonnes. It features electronic controls for
its highpressure common rail fuel system
and delivers up to 215 hp (160 kW).
Meanwhile, its 3.8 litre counterpart is
a 4-cylinder model pitched at excavators
and loaders of up to 17 tonnes.
Perkins has launched its new engine
complying with EU stage IIIB/US Tier
4 Interim emissions limits – which it
believes will find a wider global market
includingChina.
Releasing the 404F-E22TA at Bauma
China, thecompany said its latest entrant
featuring electronicmanagement systems
could deliver a 7% fuel consumption
saving against previousmodels.
Its compact four-cylinder 2.2 litre
turbo-charged engine is targeting the
wheeled loader and six tonne excavator
market. It is said to be the first of its
size using common rail direct injection
technology backed by electronic control.
Meanwhile, Danfoss has introduced its
innovative Reverse Displacement Motor
(RDM) for construction equipment.
Thisoffers reversecircuit functionalitywithoutexternal
values –which the company saidwas unprecedented
in the industry for hydraulic systems.
It is said to be ideal for fan drive systems, it is
reportedly capable of assisting in delivering 10-15%
power savings and a 15% average reduction in system
costs and reduced complexity.
Broad application
A further key development in hydraulics has
been released by Hawe with its V30E-270 variable
displacement axial-piston pump.
The company said it has been designed for a broad
range of demanding applications inmobile hydraulics,
it can be usedwith concrete pumps, harbour cranes or
Dana’s range of components includes
its Rui Ma transmission for wheeled
loaders.
Cummins had a strong presence
at Bauma China in Shanghai,
with two new engines including
the QSB7.
Danfoss has introduced its displacementmotor promising
up to 15% enhanced performance.
