SANDVIK DT1132i
“Optimization of drill and blast means taking
into consideration the changes in rock blasting
and other changes in the environment,” explains
Salo. “An e ectively-controlled blast results in
good pull-out, a restricted fracture zone and
greater rock strength around the tunnel.
Furthermore, length and
detonation can be tuned to the
permitted vibration level and
geology. iSURE 8.0 helps to
achieve this, as it provides
a set of templates for
editing and feedback
functions to achieve the
best possible result from
the blast, with blast
patterns being easily
edited to match the design
parameter.”
Re ecting the changing
environments and conditions operators
work in, improvements to the so ware are being
made regularly – Sandvik’s aim is to provide
updated versions of iSURE on an annual basis.
e RD535 rock drill, automated drilling
features and new rock tools mean that the
DT1132i delivers the results required, but with
40% less exhaust particles, up to 20% higher
penetration rate and with 25% more side coverage.
Precise control
Operators have at their disposal a number of
technologies for more precise performance. First
and foremost is the Sandvik Integrated Control
Architecture (SIKA) control system technology

“THE BOOM HAS TO BE VERY VERSATILE,
AND CAPABLE OF SUPPORTING THE HIGH
POWER ROCK DRILL IN FACE, BOLT,
INJECTION AND PROBE DRILLING”
Tommi Salo, Sandvik product manager for tunneling drills
for managing the 625Nm of rotational torque
o ered by the drill.
“SIKA is a platform which we are using to
build all of the i-series drill rigs,” says Salo. “It has
intelligent and automated features but it also
makes it possible to use the same so ware
and hardware components across the
eet. Having the same
components means, for
example, faster learning of
the system and a shorter
lead time for the spare
parts.”
Torque-based, semi-
and fully-automatic
drilling features are
available as optional extras
that enable drilling to a
prede ned depth.
Boom control
Another area where operator control has been
enhanced is the boom function. Now easier to
control, the triple boom bene ts from more
exible kinematics that speed up correct
positioning. Together the three new SB160i
telescopic booms o ers a total potential coverage
area of 190m2. Each boom, optimized with a
front wrist structure, provides 1m additional side
coverage as standard, and 4m side coverage with
telescopic adjustment. Fully-proportional boom
control gives accurate and fast manual handling.
“ e boom has to be very versatile, capable of
supporting the high power rock drill in face, bolt,
injection and probe drilling,” explains Salo. “Our
boom has more degrees of freedom of movement,
which makes it easier to do drilling in many
di erent directions. ere are also multiple
automated features to help the operator to
position the boom.”
Customers can opt for an additional SUB5i
utility boom capable of a maximum load of
510kg. Turning to the operator space, Sandvik
has given a lot of attention to ensuring the driver
of the machine is at his most comfortable.
e vibration-dampened cabin designed for
the new rig has acoustic windows and provides
all-round visibility. A ltration system minimizes
unwanted dust entering the cabin and meets the
EU6/7 requirements on this, while doorways are
located at the rear to help maintain operator
focus on the job.
Safety was also a high priority and the cabin is
falling object protection status (FOPS) compliant
and are accompanied by durable covers.
Comprehensive diagnostics information is
integrated into the operator’s display supporting
the intent to make the in-cab experience as
ergonomic as possible. Equipped with a
Cummins B6.7 Stage V diesel engine, the vehicle
can draw on 164kW of power available and meet
the latest emissions standards.
All told, Salo is con dent the global mining
industry will be well served with Sandvik’s newest
edition to its underground drilling rig family.
“I think we have succeeded in design as we
planned to do,” he says. “ e jumbo has given
15% more production in the same time unit
compared to old model which has to be kept
a great result.” iVT
