andvik Construction is
expanding its mobile
crusher range with the
introduction of the new QS441
and QS331 track-mounted cone
crushers. Its QI341 impact crusher
is now available with an optional
hanging screen system, and the
company has also unveiled the
QE141, the latest incarnation of
what it says was the world’s first
mass-produced tracked screen, the
Robotrac.
The QS441 and QS331 have
Sandvik’s S-type gyratory cone
crusher at their heart, a unit
which has been used in stationary
applications for over 30 years.
Michael Brookshaw, distributor
manager for mobile crushers and
screens in Europe, the Middle East
and Africa (EMEA) said Sandvik
was using the standard frame from
existing tracked machines and the
S cone gyratory cone which it has
been selling “for decades”.
“The big thing is we’re using
standard technology that we’ve
been using for many years, but
what we’ve done is put two parts
of the technology together,” he
added. “Everybody said ‘We need

vibrating grid, which is tipped by
remote control.
Alternatively, the QE341 can
be fitted with fine grade meshes
for precision screening and sizing
applications.
“There is improved
serviceability,” said Mr Brookshaw,
“With an on-board operator – a
simple PLC (programmable logic
controller) system, with everything
colour coded. We don’t need to
have any writing on it.”
New website
A new website for the mobile
part of Sandvik’s business is about
to go live. The site, at www.
sandvikmobiles.com is designed to
provide quick, simple navigation,
to be multi-lingual – it will
be available in eight different
languages – and customer focused.
There will be different versions
for the iPad and for smart phones.
The dedicated smart phone version
will be more product focused than
the corporate site, but the full site
version will also be available to
smart phone users.

as good as a big stationary unit,
because a stationary unit is a much
more expensive and much larger.
“What we are trying to do is to
get a big stationary unit into a
small block that we can transport
around the world. The bottleneck
in units is usually the screens, and
this unit has a 1.5m x 4.2m screen
– that’s huge for this size of unit.
The QI341 is available with an
optional hanging screen system,
which Sandvik said would allow
customers an even greater return
on investment by being able to
produce accurately sized products
for immediate use.
Also new is the QE141 mobile
scalper, which is the latest
incarnation of the Robotrac track-
mounted screener made famous
by Extec, a company Sandvik
acquired in 2007.
“The Robotrac came out in
1995, and this unit changed the
world market for mobile crushers
because before that it was a
wheeled market with very little on
tracked,” said Mr Brookshaw.

that cone on that frame’, and
that is basically what we’ve done.
We’ve made changes to the frame
– not major changes – and we’ve
managed to put this very tall cone
on to the frame.”
The S-type cone can accept a
feed size up to 90% larger than
current standard cones. This means
it can be paired with a high output
primary crusher or even be used as
a primary crusher itself in gravel
applications.
The larger QS441 56 tonne
class unit will feature the CS440
cone, while the smaller, more
compact 36 tonne class QS331,
incorporates the CS430 cone
crusher. There is a choice of three
concaves, and four bush settings to
control the closed side settings and
material gradation. It is capable of
producing large reduction ratios,
with minimal fines.
Impact crusher
Of the QI341 impact crusher,
Mr Brookshaw said, “It is now a
crusher and screener in one. The
big thing about this unit is the
screen box. A lot of these are a
compromise as they can never be
