A clear advantage of Hägglunds CMp is its
integration with Bosch Rexroth’s total service
offering
and take corrective actions in time is one aspect,
because it means that maintenance can be
budgeted more effectively. But another is
achieving more with the existing drive
equipment.
“Besides helping customers predict and avoid
unplanned operating stops, we can use
Hägglunds CMp to help them optimise their
systems for better efficiency,” says Ljungdahl. In
other words, Bosch Rexroth experts can use the
health index to see not only potential failures,
but also potential improvements. As Ljungdahl
explains, “The high flexibility within Hägglunds
hydraulic drive systems lets us adjust the motors
and pumps to better match their actual use, or
even reconfigure the drive for new power, torque
or speed characteristics.”

For Wolfram Ulrich, such optimisation is in
clear focus as the service moves forward. “The
Hägglunds CMp te chnology gives us an
opportunity to go beyond predictive
maintenance, to actually optimise the operation
of the installed system within its application,” he
says. “The more we can understand how a
system is operated, the more we can suggest in
terms of energy-saving and productivity
improvements, for example.”
In a more distant future, Ulrich sees the
possibility of an entirely different business model
for Hägglunds drive systems. “Today we use
Hägglunds CMp mainly to secure reliability and
lower the operating costs of our drives,” he
explains. “But as our connectivity and analyses
become more refined, we may be able to shift
our focus further. Instead of hardware, our
customers might buy performance in terms of
torque and speed.”
Whatever direction the service takes, however,
its core will remain unchanged. The success of
Hägglunds CMp will remain rooted in its
integration of technical and human
components.
“The value is not the data, but in the ability to
interpret the data and use it to act,” says Mattias
Ljungdahl. “Predictive maintenance is not about
sensors or even algorithms. It’s about boosting
the customer’s reliability and profitability
through insights and expertise.” IM
