TECHNICAL INNOVATIONS
The operator interacts directly with the machine's electronics via joystick and onboard display.
performance. " The working hydraulics
can be precisely controlled with short
response times, " Fabbri said. " At the
same time, we can configure the system
parameters very easily. We secure
these advantages in the long term because
the eOC BODAS system is designed
to be open and scalable. "
Sampierana also can point to improvements
in terms of sustainability.
Less control oil is required because several
hydromechanical controller axes for
pressure, flow rate and torque have
been combined into one. In addition,
the dynamic adjustment of the control
parameters minimizes the energy consumption
of the entire hydraulic system.
" On this basis, we can comply more
easily with current regulations regarding
ecomobility, emissions and efficiency
and support our customers even better
in meeting their climate protection
targets, " Fabbri said. " This is an important
competitive factor. "
As a result of the reduced pump variance,
Sampierana also reduces the administrative
effort from development to
assembly and logistics to service, including
spare parts management and
aftermarket. Feature updates and troubleshooting
are carried out via the
BODAS Service Tool, which among other
functions includes a detailed guide to
pump commissioning.
The electronification of working hydraulics
at Eurocomach demonstrates
how compact work machines can benefit
when complexity is shifted from
hardware to software. Following the
successful deployment in its mini excavators,
Sampierana decided to extend
the Bosch Rexroth eOC system to other
Eurocomach models.
" Thanks to eOC BODAS, we can now
map a wide range of functions with a
consistent hydraulic system and adapt it
precisely to the type of work to be performed
and the operator's preferences, "
Fabbri said. " While we delight our customers
on the jobsite, we benefit internally
from leaner processes and high
degrees of freedom for the coming
generations of vehicles. "
