ConExpo 2020 was for Carraro Group the
ideal occasion to demonstrate its capability
to develop state-of-the-art solutions in keeping
with the evolution of markets requirements.
Within a scenario that registers massive
urbanisation (by 2050 nearly 70% of the global
population will live in urban areas) and an
extensive migration from the rural areas of
developing countries, the need for infrastructure
is expected to grow constantly. This means new
constructions, more maintenance and
a substantial growth in demand for equipment.
In this context the new global motto is ‘do more
with less’. Productivity and efficiency – such as less
fuel consumption – are the key pillars.
The Carraro way
In the construction equipment sector, as in
agricultural, Carraro offers a wide range of solutions
from basic to premium, leveraging as much as
possible the design modularity and scalability to
address the most advanced solutions together with
the ones using more ‘frugal’ technology. This way
best cost and performance are obtained.
That this is possible is thanks to a solid global
footprint, with state-of-the-art operations and
R&D centres in Asia (China, India), South America
(Argentina, Brazil) and Italy. All are centrally
coordinated from the Italian headquarters.
The organisation enables a deep understanding
of local market requirements that, combined with
a consolidated know-how integrating hydraulic
and electronic competences to the mechanical
ones, makes Carraro a real global system provider.
Today the company is able to offer a
comprehensive product portfolio of complete
drivelines for all the most popular construction
equipment machines. These include backhoe
loaders, tele boom handlers, compact and
small wheel loaders, wheel excavators, and
soil compactors. In addition to this, Carraro
Engineering is able to develop innovative solutions
for further CE and special applications.
Electrification: the new path
Leveraging the 25 years of experience in
development and supply of integrated drive
systems for material handling electric traction
applications, Carraro more recently extended its
portfolio to include hybrid electric machines and
electric powertrains.
The company can
now offer the design of
the whole system,
combining its
traditional mechanical
know-how with strong
electric/electronic
competences. Able to support
all electric architecture
topologies, Carraro can lead the
complete e-powertrain through
a dedicated ECU, then sizing and integrating
the most suitable electric modules: from
motors and generators, to inverters,
batteries and battery management
systems to obtain the best performance
for the entire system.
ConExpo highlights
From its booth in Las Vegas, Carraro displayed
three examples of its innovations, both in terms
of products and service capabilities, highlighting
its unique value proposition, from component to
complete machine.
The eTCH90 Long Drop, a torque converter full
powershift transmission, is designed to become
a parallel electric hybrid unit, suitable for several
equal size tire machines, starting from tele boom
handlers. The eTB220C, a gearbox specifically
developed for full electric applications, is able
to have minimum power losses even at high
input rotation speed. Lastly the FLS 3.2 is a full
powershift hydrostatic gearbox that can fulfil the
performance demand of several machines, ranging
from small wheel loaders to tele boom handlers.
All the gearboxes are controlled by software
developed to run in the Carraro proprietary ECU,
fully compliant with ISO 25119 (functional safety).
For all the powertrain applications, Carraro can
achieve further fuel efficiency and productivity
through the simultaneous control of the whole
powertrain (i.e. engine and transmission) thanks to
its competence in developing control software to
be injected in its proprietary ECUs. iVT
