Every three years, Messe München hosts
the bauma trade fair in Munich. Billed as
the world’s leading sector event for construction
machinery, building material
machines, mining machines and construction
equipment, the exhibition space
totals 640,000 m2, making it the largest
trade show on earth.
For 2019, Messe München expects to
have 3,500 exhibitors from 60 countries.
Unlike other large equipment fairs, bauma
has dedicated a portion of its program
to mining. Mining represents roughly
20% of the exhibition. The mining sector
has its own hall: C2. According to Messe
München, a total of 578 exhibitors indicated
they are involved with mining,
extracting and processing raw materials.
Visitors reviewing exhibitor information
will note the mining symbol and the
phrase Mining Inside. Miners hoping to
make the most of their time, however,
will need to narrow the field. For them,
E&MJ offers a selection of “must-see”
stands. What follows is a compilation of
announcements leading up to the event.
ALLU’s attachment crushes as it loads.
ALLU Offers Mobile App
In addition to its existing state-of-the-art
screener/crusher equipment being exhibited
at the show, ALLU will also be introducing
new products and solutions, including
a new Mobile App with new functions
aimed at helping improve productivity,
job-site safety and customer service.
The new Mobile App is the latest development
for ALLU’s communication
system. It provides an intelligent digital
solution for customers and operators to
obtain accurate and timely operational
information, thereby maximizing safe
and productive use of ALLU equipment.
Through easier and improved contact
functionality, customer support is also
enhanced through the new features of the
app. There will be live demonstrations
throughout the show from the ALLU stand
(FN.1021/2 in the open area, north).
Reliable Conveyors for Rough Terrain
The BEUMER Group (Hall B2, Stand
413) will provide information on their
efficient transport solutions for the mining
industry. Overland conveyors and pipe
conveyors transport various raw materials
over long distances and often through
rough terrain. This is generally faster,
more cost-efficient and environmentally
friendly than trucking.
High angles of inclination and tight
curve radii are not a problem. BEUMER
Group relies on camera-equipped drones
for the planning, projection, implementation
and documentation of these systems.
Using special software solutions, the system
supplier evaluates the aerial photographs
photogrammetrically to generate
digital terrain models.
The BEUMER product range also includes
stackers and bridge reclaimers
for storage yards, whether with or without
blending bed systems. These stack
bulk material and guarantee a maximum
blending effect. Users can also efficiently
homogenize large quantities of different
bulk materials and bulk material qualities
and ensure the uniformity of the raw materials
used. For efficient loading, BEUMER
Group supplies ship loaders with fixed
booms and extendable telescopic belt
The Brokk TE160 rock drill attachment.
Brokk Introduces Rock Drill Attachments
As Brokk’s machines have become more
technically advanced and market demand
for mechanization has increased, demolition
robots are increasingly used for a
more varied range of applications requiring
Over the last few years, to meet this
demand, Brokk has developed new attachments
and upgraded its machines to
work well with a wider range of tools. One
of those is a rock drill attachment. These
are customized and fully integrated with the
control and operation of the Brokk robots.
The range has been extended with the powerful
new TE 326 drill attachment used on
the new Brokk 300 and Brokk 500 models.
This creates a complete range of rock
drills for Brokk machines, from the small TE160 used on the compact Brokk 110
to the powerful TE360 used on the biggest
Brokk machines. All drill rigs are
characterized by their exceptional performance-
to-weight ratio, the company said.
Technology Solutions for Lubricants
Evonik will present two of its leading
technology solutions at bauma (Hall A3,
Stand 244): DYNAVIS technology, which
optimizes the viscosity of hydraulic fluids;
and industrial gear oil formulations
based on NUFLUX technology, which
perform as well as synthetic based fluids,
at a lower cost, the company said.
Changing from a standard hydraulic
fluid to one formulated with DYNAVIS
technology generates many benefits, including
increases in machine productivity
and improved fuel efficiency, according
to Evonik. Additional benefits include
the machines operating more efficiently,
reacting better, needing less frequent
service, and suffering less wear and tear,
ultimately extending their service life,
according to Evonik. And, this pays off
quickly, most notably in extremely demanding
applications, while also assuring
higher returns, lower energy consumption
and reduced CO2 emissions.
Companies who focus on mining, road
construction, demolition or earth-moving
have realized increased profits, with peak
efficiency gains reaching up to 25%, according
to Evonik. A current test project
on a Hitachi EX1200 hydraulic excavator
at a mine in the Kuznetsk Basin, Russia,
demonstrated that the use of DYNAVIS
technology yielded 7.9% growth in coal
extraction as measured in bank cubic meters
Oils formulated with NUFLUX technology
are largely equivalent to synthetic lubricants,
and even surpass them in some
respects. In fact, during a recent field trial
with pump gear in South Africa, a higher
degree of efficiency was measured with
aerators that promises to pay off. This
made the plant’s decision easier to fill 26
of their gears in the water treatment system
with NUFLUX formulated oil, saving them
approximately EUR 17,500 per month.
Hella’s RokLUME projects a red danger zone on the
Using Lighting Systems to Improve Safety
ground around the excavator.
Lighting and electronics expert HELLA
(Hall A5, Stand 436) has developed the
VISIOTECH projection technology and has
already launched four products to help
in these situations: The LED Projection
Module, the warning lights SL60 LED,
Module 50 LED Spot and — particularly
for mining — the RokLUME S700 Red.
The LED Projection Module was specially
developed for original equipment
and projects an exclamation mark as a
warning symbol on the ground near the
machinery. For the SL60 LED and Module
50 LED Spot warning lights, a special
lens optic allows the light rays to converge
so much that a strip-shaped warning line
or warning spot is projected on to the
ground. This application serves to warn
other vehicles or pedestrians of an oncoming
vehicle. The lines projected in front of
a vehicle can, however, also be used as a
means of simpler vehicle navigation.
The RokLUME S700 Red LED warning
light utilizes the same principle and
projects a wide red marking on to the
ground, thus highlighting the danger
zone around the vehicle. Thanks to its
powerful light output, the warning light
can also be used on vehicles with high
mounting positions and is particularly
suitable for mining vehicles.
Liebherr will unveil electrically powered hydraulic shovels at bauma.
Liebherr will give bauma attendees a unique
chance to experience its latest innovations
first-hand, which range from construction
machines, material handling, mining and
components. Visitors can look forward to
seeing many new technologies and other
practical innovations at Liebherr’s 14,000-
m2 outdoor stand (809-813) and its indoor
stand (Hall A4, Stand 326).
For the mining division, visitors will
see demonstrations of the R 9200 E electric-
drive excavator. This will be a world
premiere for a machine in this class. Together
with the R 9200 E, Liebherr-Mining
will present the new T 236 diesel
At the fair, Liebherr Components will
also reveal the demo version of an app
that shows the extensive functionality of
all Liebherr’s condition monitoring components,
from diesel engines to energy
storage, hydraulics, transmissions and
slewing bearings. In the future, this will
enable machine manufacturers to inform
fleet managers, service personnel and
machine operators about the condition of
Mobil Elektronik wants to equip mining machines with rear-axle steering.
Using Lighting Systems to Improve Safety
Rear-axle Steering Systems
Electrohydraulic steering systems for rear
axles have been standard in commercial
vehicles and complex construction machinery,
such as cranes, for many years.
In the case of commercial vehicles,
the use of electrohydraulic auxiliary steering
is primarily to ensure compliance with
the legal requirements. Without a steered
rear axle, the legally defined minimum
turning radius cannot be maintained.
Most other machines, such as twoaxle
loaders, usually have hydrostatic
front-axle steering. It is obvious that
these machines could also benefit from
Mobil Elektronik (Hall A3 /Stand 115)
can equip these machines with the same
features that are already standard in mobile
cranes. Operation will be easy and
convenient. The steering mode can be
changed at any wheel position. The synchronization
of the axles with each other
is done automatically.
The Metso MX cone crusher.
Advances in Mineral Processing and More
Along with new crushing and screening
solutions, Metso (FS.1111/2) will unveil
a groundbreaking innovation for off-highway
trucks, enabling mines and quarries
to haul more with less. This major product
launch will expand Metso’s offering
into completely new territory and help
customers reach a higher payload while
lowering their operating costs.
In addition, Metso will showcase a
broad range of equipment, wear and
spare parts as well as services designed to
help make operations more efficient and
assets work harder. The solutions to be
featured will include cone crushers and
slurry pumps. The Metso MX cone crusher with patented
Multi-Action crushing technology designed
to cut the operational costs of crushers
and to provide more uptime compared
to traditional cone crushers, the company
said. Since its introduction in 2017, Metso
has sold 50 MX crushers worldwide.
The Metso slurry pump range is optimized
for maximum uptime and reduced
operating costs. The slurry pump maintenance
slide base offers fast, safe and easy
wear component change or pump inspection.
Leaving the suction and discharge
pipe undisturbed during inspection, the
entire rotating assembly and motor configuration is slid back.
Rock Bolting Systems
Normet’s line of auxiliary equipment for
underground mining applications is well
known. The company’s Rock Reinforcement
business line has developed new
innovative products that can help solve
some of the toughest challenges.
The D-Bolt, for example, is widely used
as part of the ground support system in
some of the largest and deepest mines.
The company’s locally anchored, self-drilling
hollow Rock Bolts can be used in combination
with its construction and mining
chemicals, where conventional systems
are not delivering the desired results. In
addition, Normet is devoting time and resources
to further develop the next generation
of rock reinforcement systems, creating
even safer underground environments.
The D-Bolt represents the new generation
of energy-absorbing rock bolting
systems, specifically designed for efficient and reliable rock reinforcement, in
both squeezing and burst-prone strata
conditions. The technology is based on
a smooth steel bar with a number of anchors
along its length.
The newest addition to the D-Bolt family
is the Connectable D-Bolt, a system that
is extendable through specially designed
couplings. This bolt type is especially effective
for smaller profile spaces where
there is a need for a longer bolt anchoring
offering an alternative to cable bolts.
For areas where ground conditions are
very difficult and demanding, Normet designed
an innovative, patented bolt combining
the features of the Self Drilling Anchor
(SDA) and D-Bolt. Normet produces
two types of anchor taking into consideration
design and load bearing capacity. For
the North American mining market, Normet
designed the bolt to reflect Nevada mine
conditions, the SDDB — Nevada type.
The anchor is a 2,400-mm long Self Drilling
Hollow Bar made from a single piece seamless tube with a 32-mm diameter. The
thread is ISO R32 rolled with uneven length
from each side. The material for the SDDB
Nevada type has been carefully selected to
respond to a customer’s inquiry for yield
load and elongation at break. The bolt is
typically used for single length applications
although it can be extended with couplings
to reach the desired length where necessary.
This anchor utilizes a drill bit and longer
root threaded section for anchorage.
Scania will display five trucks at bauma.
Scania’s V8 Celebrates
Scania will display five construction
trucks in total: four inside the exhibition
hall and one outside it. What they all have
in common is the robustness and productivity
level for which Scania is well known.
At bauma, Scania is also showing connected
engines for equipment, vehicles
and vessels that facilitate fleet monitoring
and optimized uptime. This service is
based on the vast knowledge Scania has
gained from having connected 350,000
buses and trucks.
The company is also celebrating the
Scania V8 turning 50. It made its debut
back in 1969. “In its latest edition, it
is still the pre-eminent solution, always
delivering like no other,” Alexander Vlaskamp,
senior vice president of sales and
marketing. “Regardless if it’s emotion or
logic behind a purchase, the V8s never let
our customers down.”
Superior Industries (Hall B2, Stand 107),
an American builder of crushing, screening,
washing and conveying equipment,
said its presence at bauma 2019 will be
three times larger than previous editions.
In addition to wet processing equipment,
Superior will display conveyor components,
including the Chevron Pulley, a
V-shaped wing pulley that deflects oncoming
rocks; the Moxie Roll, an idler made
from a composite blend, which are 50%
lighter and at least three times quieter
than steel; the High Performance DT Idler
for improved performance in high capacity
applications; and the Exterra SFL Dual
Belt Cleaner, a primary and secondary
scraper sharing one mounting pole.
The lizard mobile-stacking bridge from thyssenkrupp Industrial Solutions can be used for stacking ore on
pad and tailings.
thyssenkrupp Industrial Solutions will present
its new mobile stacking bridge, “the lizard.”
This unique solution for heap leaching
and dry tailings stacking combines two
proven technologies — the conveyor bridge
and the tripper car — in a new way. The lizard
decouples the crawler-mounted tripper
car from the conveyor bridge, enabling it to
be controlled independently of the bridge.
Decoupling the tripper car from the
conveyor bridge has several advantages:
The transitions between the bridge segments
are easier as there is no stress
from a traveling tripper car on top of the
bridge. As the loads on the bridge sink,
the overall construction of the bridge outweighs
the additional chassis and structure
of the tripper car. This way the product
saves weight and costs, according to
the company. In addition, a larger dump
height and longer outreach are possible.
“Especially with longer conveyor bridge
systems the lizard pays off with lower investment
cost and less fatigue issues on
the bridge structures,” said Stefan Ebert,
global product lifecycle manager. “Since
the tripper car is not traveling on the bridge,
the loads for dimensioning the bridge are
significantly reduced,” said Burhan Osmani,
engineer at thyssenkrupp Industrial
Solutions and the inventor of the lizard.
Operators benefit from a slimmer,
lighter bridge structure, lower bridge
height, smaller bridge crawlers and lower
ground pressure. The same lightweight
design can also be used for the reclaiming
bridge. Fatigue issues otherwise caused
by cyclic loads from the tripper car are
completely eliminated, the company said.
This significantly reduces maintenance
requirements and increases availability.
A key advantage of the lizard is its
multi-crawler chassis. thyssenkrupp used
its expertise in this area to develop a
unique solution that improves productivity.
A multi-crawler chassis with no override
control, the so-called “float system,” is attached
to the tripper car. The double crawlers
with no steering cylinders ensure unrestricted
maneuverability in all directions.
The system can be attached to any crawler
to avoid the large turning circles of conventional
gearing systems. “To be able to
flexibly control the mechanically independent
multiple crawlers is a game changer
in mobile mining equipment,” said Paulo
Costa, head of mining systems.
The float gearing system allows the lizard
to be operated flexibly: When a stacking
row is completed, the tripper car is at
either the front or rear end of the bridge.
Before moving to the next stacking row,
the tripper car has to turn its crawlers
through 90° in the direction of bridge
movement without impacting the performance
of the system. In this way, the
tripper car and the stacking bridge move
backward or forward as one stacking system
depending on the stacking plan.
Tsurumi KTZ series submersible
Tsurumi to Launch 2 Pumps
No two mining projects are the same,
which also applies to the dewatering systems.
Two new pumps by pump manufacturer
Tsurumi offer greater scope to come
up with ideal solutions. With its innovations
KTZ415 and KTZ615, the Japanese company
has outdone its series of professional
drainage pumps for difficult applications.
The 615 is the new top model of the
KTZ series that now comprises 15 models.
Thanks to a motor output of 15 kW, the
aggregate achieves up to 2,800 liters per
minute (l/min) with discharge heads of almost
40 meters (m). In contrast, the 415
with the same motor only pumps 2,000 l/
min, but up to a maximum height of 55 m.
Both submersible pumps can cope
with heavy particulates with grain diameters
of up to 12 mm. The pumps are
pressure-resistant to a submersion depth
of 25 m and have a pressure port with a
diameter of four (model 415) and/or six
(mode 65) inches on the outside thread.
Tsurumi will be displaying many other
pump models (Hall A6, Stand 338), as
well as another innovative that it still under
wraps but which will be launched in
2019. Engineering enthusiasts can also
look forward to exhibits of cutaway pump
models and live wet applications.
Smaller Surface Miners
Wirtgen’s 220 SM 3.8/220 SMi 3.8 surface
miner selectively mines raw materials up to
a cutting depth of 350 mm and a uniaxial
compressive strength of 35 megaPascals
(MPa). Thanks to its 3.8-m-wide cutting
drum designed specifically for soft-rock
mining, the compact surface miner achieves
maximum productivity at low operating
costs and is perfect for use in small to large
mining operations, according to Wirtgen.
The 220 SM/SMi’s cutting drum has
been designed specifically for demanding
windrow applications in soft rock, such
as coal or salt. Maximum cutting performance
combined with the ideal use of engine
power and low specific fuel consumption
allows raw materials to be mined in
an extremely cost-effective process. Six
different adjustable cutting-drum speeds
ensure that the machine can be perfectly
adapted to the material being extracted.
This leads to a significant reduction in
pick wear, minimal diesel consumption,
and increased productivity, which translate
into an impressive daily output and
low cost per ton of extracted material.
Wirtgen’s 220 SM 3.8/220 SMi 3.8 surface miner selectively mines soft rock.
In surface mining, the continuous
availability of the machine and its safe
operation are of critical importance. This
is why the surface miner’s components
are designed to achieve a long service
life, even under extreme conditions. For
example, filters in all circuits and a pressurized
hydraulic reservoir ensure maximum
purity in the hydraulic system and,
as a result, safe operations. The clean
oil in turn prolongs the service life of the
downstream components and thus increases
the availability of the machine.
The 220 SM/SMi also meets occupational
safety requirements in surface mining
thanks to the standard-equipped ROPS/
FOPS operator’s cabin. The cabin features
additional soundproofing and vibration
isolation, allowing the operator to work for
several hours without the risk of fatigue.
The ergonomically designed and clearly
arranged controls are integrated into the
armrests of the driver’s seat, and all of the
machine’s key functions are logically incorporated
into the multifunctional joysticks.
This means that the operator can operate
the machine intuitively in just a few steps
and fully concentrate on high-precision
mining. The state-of-the-art, fully air-conditioned,
large-capacity cabin also features
generously sized windows, giving the operator
a direct view of the cutting edge and
with it, the results of their work.
