Sandvik Mining and Rock
Technology has expanded its
existing Ranger DX series of
surface top-hammer drill rigs
with two non-cabin Ranger
DXR versions. Based on the
reliable Ranger DX600 and
DX800 models, the two new
machines are the Ranger
DX600R and DX800R,
respectively. Designed to reach
places that are off-limits to
operators, they offer all the
characteristics of conventional
Ranger DX series drill rigs,
including a large drilling
coverage area, from the
standard 17.6m 2 to an optional
26.4m 2 , but in a lighter and
more mobile package.
Providing a solution for
hazardous conditions where
safe and productive drilling
requires advanced radio
remote-control capabilities, the
non-cabin Ranger DXR drill
rigs are particularly useful on
unstable benches, where the
operator can choose the best
position in terms of safety and
visibility. The remote-control
panel also includes tramming
control functionalities for fast
hole-to-hole movements and
precise hole spotting.
The revolving superstructure
is said to offer unparalleled
drilling coverage and
superior stability, thanks to
its innovative counterweight
solution, and provides a solid
foundation for drilling even
on extreme terrain. In terms
of productivity, the revolving
superstructure, together with
powerful rock drills and Rock
Pilot+ drilling control system,
allows the Ranger DXR to
drill up to 60% more holes
per set-up compared with

conventional top-hammer
drill rigs.
Ranger DXR series rigs
are designed to drill 64mm
to 127mm hole sizes, with
drill rod sizes between 38mm
and 51mm. The machines’
standard configuration can
be further boosted with more
than 30 useful options, such
as extended superstructure
turning radius, advanced
measurement systems, and
upgraded dust control.
Also, for quarry operators
working close to residential/
urban areas where strict noise
limits may apply, an optional,
ruggedly designed noise
guard cover offers a total
noise reduction of more
than 10dB.
BossTek, global innovators
in dust- and odour-control
technology, has improved
its family of self-powered
dust-suppression equipment
with Tier IV Final-compliant
generators. BossTek made
the announcement with the
debut of the new DustBoss
DB-60 Fusion, a field-proven
suppression system driven by
a reliable 25hp electric motor
and paired with a genset
powered by a heavy-duty, four-
cycle, indirect-injection diesel
engine.
Designed, engineered, and
assembled in the US, the
generator features a dual-
containment fuel cell, heavy-
gauge lockable enclosure, and
oversized brushless alternator
for easy starting.
Permanently mounted on
a rugged road-going trailer,
the Fusion line-up provides
a means of delivering mobile
dust-suppression technology to
sites that lack a readily available
power source. BossTek plans to
unveil two other Fusion models

in early 2019, giving customers
the ability to select the size and
coverage range needed to best
suit their operations. The new
generator series is designed
with sound attenuation and
a multi-voltage switch, with
utility power outlet in all
voltage modes. The digital
engine/generator controller is
equipped with single-button
stop/start and a 300ℓ fuel
capacity, giving the units a
runtime of more than 24 hours
at a prime rating of 45kVa.
The Tier IV-compliant
engines are designed to
significantly reduce emissions
of particulate matter (PM)
and oxides of nitrogen (NOx)
to near zero levels. Relative to
previous emissions standards,
Tier IV-compliant engines
reduce emissions by more than
95% for most construction
equipment.

then launches millions of tiny
droplets with a powerful fan.
Atomised mist droplets of
50–200 microns in size are
thrown out in a 60m cone at
an adjustable 0–50 degrees
elevation angle, capturing
airborne dust particles and
dragging them to the ground.
The system is able to deliver up
to 5 834m 2 of coverage. Unlike
industrial sprinklers used for
the same purpose, which can
require hundreds of gallons of
water per minute, the DB-60
uses around 87ℓ/min to help
avoid pooling or runoff.
A touch-screen panel
for controlling the dust-
suppression unit is encased in
a NEMA 3R cabinet, allowing
operators to control oscillation,
booster pump, fan, and water.
The cabinet is constructed for
outdoor use and designed to
provide protection against dirt,
dust, rain, sleet, snow, and ice.
Equipped with an in-line,
75-mesh, 200-micron filter,
the unit can be specified
with special filtration to
accommodate non-potable
water sources. In addition, the
new design can be optimized
with a variable-frequency drive
(VFD) to adjust fan speed
precisely. An optional dosing
pump is available for precise
metering of additives to further
enhance particle control.
