Building for the future
that the company says is rugged enough to withstand wide
temperature ranges andwater depths.
Multiple inputs and outputs, including three CAN ports,
provide flexible configurations, according to the company.
Eaton says it uses one of the fastest processors on the market
for its control systems. In addition, memory can be allocated to
perform data logging functions that can reduce cost by taking
the guesswork out of maintenance by predicting problems
before they happen.
The new line includes two displays – 4.3 and 7 inches (109
and 178 mm). Like the controllers, its high-quality display
screens are extremely rugged, built to withstand high and low
temperatures, and are readable in direct sunlight.
Cabin controls
The industrial division of Curtiss-Wright Corporation
has supplied Penny + Giles JC8000 joystick controllers to
Netherlands-based container handling systems company VDL
Containersystemen.
Its Containersystemen’s ‘classic’ control system for hooklifts
uses cabin-based air controls to operate
the hydraulic main valve that drives the
hydraulic cylinders.
This allows the driver to operate
multiple (but not simultaneous)
functions, including thehooklift’s sliding
arm or sliding/tilting arm.
With useable spacewithin truck cabins
becoming smaller, recent installations
have been mounted to the other side
large hydraulic excavators.
An extensive controller program
supports its deployment options.
The V30E-270 has been designed for
an operating pressure of up to 350 bar,
with a peak pressure of 420 bar. The
volume flow clocks up a maximum of
400 litres at 1,500 rpm,with a geometric
displacement of 270 cm

As an integral part of hydraulics
systems, specialist fluid manufacturers
such as Dynavis have reported success
in enhancing the performance of
construction equipment.
Amongoneof itsmost prominent cases
was a consultancy role with an Italian
construction with Ghizzoni contractors.
Its found that a 10% improvement in fuel efficiency could be
achievedwith the company’sfleet of 14Case excavators through
the use ofDynavis, according to the company.
It also found that older excavators saw a performance
improvement through the company’s aftermarket hydraulic fuel
additive.
A spokesperson for the company said, “More than once,
Ghizzoni machine operators stated that all of a sudden their
excavators could perform tasks they were unable until then.
An explanationmay be, that after years of intensive utilisation,
pump and seals show increased tolerances.
“A hydraulic fluid formulated with the Dynavis technology
due to its optimised viscosity is able to at least partially
compensate for this wear indicated loss of pressure. What the
machine operators hadwitnessedwas no “new”mobility, it was
just the one the excavators hadwhen being innew condition.”
Powermanagement company Eaton has launched its new line
of Pro-FX electronic controls and software, including theHFX
controllers andVFX displays families.
It has also released its Pro-FX Control software to precisely
control machine functions formobile off-highway applications.
New HFX controllers have die-cast aluminium housing
