Volvo CE targets jobsite safety with collision
mitigation for wheel loaders
Liebherr says its parallel pump with an
electrohydraulic control system is especially
suited to machines with conceptually different
drive speeds.
The Liebherr Components product
segment also added to its axial pistons
with two hydraulic pumps in nine nominal
sizes. The company says that the new
product developments stem from the
mining and industrial sectors, as well as
maritime applications, placing increasing
demands on the availability and longevity
of machines and technology. To keep
up, the Components product segment in
Bulle, Switzerland, is expanding its portfolio
of open circuit pumps by the nominal
size of 550 cm3
used as a double pump of 1100 cm3
" Like all pumps in this product family,
, which also can be
.
the DPVO 550i is characterized by a
particular robustness. In the view of
digitalization, this product is ready to
incorporate various sensor technologies, "
said Guillaume Bonnetot, general
manager systems at Liebherr-Mining
Equipment Colmar SAS. " We are looking
forward to seeing Liebherr components
in use on our own machines. "
The LH30VO family, with nominal sizes
of 28, 45 and 85 cm3
pump of 100 cm3
, now includes a
. The LH30VO100 consists
of a modular system of eight controllers
with a variety of combination
options. The variable drive-through concept
allows the selection and addition of
further pumps, when installing them on
the machine. The LH30VO pump family
offers a range of applications from mobile
machinery and stationary hydraulics
for primary work functions to secondary
applications such as in fans, auxiliary
drives or steering systems.

The Collision Mitigation System for Volvo wheel loaders
functions only when the machine is in reverse and driving
at speeds between 3-15 km/h (1.9-9.3 mph).
Volvo Group announced its vision for
zero accidents long ago and has
launched several advanced driver-assistance
systems (ADAS) for its commercial
trucks in recent years, including the second
generation of its Volvo Active Driver
Assist with improved automatic emergency
braking. Now it's the Construction
Equipment unit's turn to take a further
step toward zero accidents at jobsites
with the launch of its Collision Mitigation
System (CMS) for Volvo wheel loaders.
CMS for wheel loaders is an automatic
braking feature that supports
operator response and helps reduce the
risk or consequences of collision when
working in reverse. It functions only
when the machine is in reverse and
driving at speeds between 3-15 km/h
(1.9-9.3 mph), regardless of what gear it
is in. Wheel loaders spend an average
of 40-50% of their time being driven in
reverse, according to Volvo CE.
The system automatically applies the
service brakes for 2-3 seconds when an
obstacle is detected, slowing down the
machine prior to impact or bringing it
to a complete stop. The initiation of
braking alerts the operator to intervene.
The company claims that the system is
the first of its kind from a constructionequipment
OEM.
" We at Volvo CE continue to proactively
develop intelligent solutions
which not only mitigate the consequences
of accidents but strive to avoid
them altogether, " said Lars Eriksson,
global product manager for wheel loaders
at Volvo CE. " This new Collision
Mitigation System is one important part
of our work to reduce the risk of accidents
and help fulfill our commitment
towards zero accidents. "
Requiring a Radar Detect System to
be fitted, it works as an additional system
to the existing range of features,
options and site services provided by
Volvo CE for its line of wheel loaders.
For stockpiling operations, the system
will remember the last slope the machine
climbed, allowing operators to
reverse down a pile without activating
it. It also can be temporarily deactivated
for specific site conditions.
The patent-pending Collision
Mitigation System for Volvo wheel loaders
was developed in-house and is a
factory-fit option currently available on
the L110H/L120H equipped with
OptiShift, L150H, L180H, L220H, L260H
and L200H High Lift wheel loaders.
Volvo CE says the system is available in
all markets around the world.
