MINEXPO PREVIEW
7.85 m. “The highly efficient shearing scaling
principle is combined with the proven hydrostatic
drive EDS, which enables quick reversing and
sensitive roof as well as side wall scaling.” The
Efficient Drive System (EDS) offers high
productivity and reduced maintenance costs.
In order to comply with the highest safety
requirements, the cabins are designed for a load
of 200 t and provide a very good overview in all
working conditions – in particular at the scaling
tools. The intelligent scaling safety system
protects both the operator and machine during
operation.
Its wide spur and low centre of gravity guarantee
high stability even in extreme gradients.
The vehicle frame of the LF-7HB is based on
the proven Super Low Profile (SLP) concept and
consequently offers an excellent overview with
its spacious cabin. Furthermore, the vehicle is
also available in a SLP option with a low profile
operator’s cabin to carry out efficient scaling in
thin-seam deposits.
The ecofriendly 180 kW, Deutz TCD7.8L6
engine complies with the highest emission
standards EU Stage IV and EPA Tier 4 Final, thus
minimising ventilation requirements.
Optionally this machine is offered with a
remote control with cameras as well as collision
avoidance systems.
Other features include intuitive two pedal
control for faster cycle times, and advanced
controls and condition monitoring systems.
Different scaling arm lengths are available.
The latest chapter in MacLean’s mining R&D
focus is the development of battery power,
engineered for life underground. Its electric

equipment safety and productivity in the hard
rock environment since 1973

propulsion system leverages high power, high
efficiency, and long cycle life battery chemistry,
sophisticated battery management and vehicle
monitoring capabilities, as well as onboard
charging that ensures compatibility with existing
mine infrastructure.
The MacLean booth at MINExpo will mark the
formal unveiling of the battery powered version
of the next generation of the company’s signature
ground support offering, the 975 Omnia Bolter.
In addition, the booth will feature a stand-alone
display of the battery propulsion system
components at the heart of the company’s
battery power value proposition. Attendees will
be able to get an ‘inside look’ at underground
electrification, welcomed by the inter-disciplinary
MacLean delegation on-hand, representing
expertise from across the company’s engineering,
product management, account management and
marketing functions.
BTI will be launching its new ScaleBOSS 3D
scaler at the event. The ScaleBOSS offers a fiveaxis boom, providing enhanced flexibility and
superior coverage in a light, compact design. The
Mine Runner APV will also be on display, a
mining utility vehicle offering more power and
increased safety with less maintenance and a
lower total cost of ownership.
Both vehicles offer BTI’s Advanced Breaking
and Tramming (ABT Control- patent pending) and
hydraulic wheel drive (HWD), providing more
traction and power with reduced emissions. BTI
says its “mining utility vehicles are a modern day
solution for a new generation of mining
productivity and safety.”
ScaleBOSS features an ergonomic ROPS/FOPS
certified operator cabin, in which the HVAC
system maintains excellent personnel safety,
comfort and visibility. The machine is optimised
for 3 x 3 to 5.5 x 5.5 m headings; and “meets the
demands of a new generation of mining and
safety.”
Mine Runner has been engineered from the
ground up to be a leader in personnel safety and
operational flexibility. “The ever increasing
Heavy-duty, compact construction makes BTI’s
ScaleBOSS easy to manoeuvre and it withstands
severe conditions. The breaker function's
dedicated, open-centre hydraulic circuit helps
simplify identification of maintenance needs
payload requirements and tramming distances
have exceeded the capabilities of the typical
repurposed highway 4x4 style truck. Unlike many
over the road type vehicles being modified for
use underground, the Mine Runner is purpose
designed and built for the underground
environment,” explains Andy Jackson, BTI
Engineering Project Leader, Mobile Equipment
Systems.
Both the primary braking (service brakes) and
the secondary braking (emergency brakes) have
been designed and tested to meet and exceed
the CSA Braking Standard and Performance for
Underground Mining Machines. CAN/CSA M424.3-M90.
Powered by BTI’s HWD fluid controlled power
train, the Mine Runner is capable of easy
customisation to optional configurations without
hindering performance or longevity of components.
Aramine’s miniLoader L120B is specially
designed for narrow section and narrow vein
underground mining. With a width of 0.95 m and
a tramming capacity of 1.1 t, the L120 is ideal for
raising productivity without the need to increase
