Bis Rexx User Manual

160-tonne mine haulage truck

Mine haulage reimagined

Rexx is the latest product to join the Bis haulage fleet, providing
increased efficiency and productivity to our customers’
operations through our integrated haulage services.

Rexx delivers:

Lower mine development costs

Rexx’s 4.8m width, even weight distribution, and ability to haul efficiently on 12%

gradients means it can operate on narrower and steeper haul roads and in tighter

cutbacks, reducing development costs, rehabilitation and environmental disturbance.

Superior fuel efficiency

Up to 40% less fuel burn leading to

significant fuel cost savings for your project.

Better safety outcomes

Rexx comes equipped with world-class

fatigue detection and driver monitoring

systems, and operators experience better

visibility and cabin access than ever before.

Increased range

With the ability to efficiently travel

up to four times further than conventional

dump trucks.

Mining for the future

Rexx’s smart design has the ability to

house proprietary automation hardware.

1 REXX

Lower mine
development costs

Mine development costs are optimised,
thanks to Rexx’s unique attributes.

Rexx has been designed with multiple
steering and driving axles, enabling it to
handle gradients of up to 12% when fully
loaded.

At 4.8m wide, haul roads and inclines can
be narrower.

The ability to haul efficiently on 12% inclines
reduces incline length and significantly
improves strip ratio, while Rexx’s
evenly-distributed weight allows for
lower-specification haul road construction.

In addition, the Bis steering system enables
a turning radius of less than 12.6m, which
allows Rexx to easily manoeuvre in smaller
spaces and turn around sharp corners.

This reduces the haul road infrastructure
costs of your operations, as well as
environmental disturbance and associated
rehabilitation works.

The unique five-axle drive and 20-tyre design
of Rexx distributes the load more evenly,
delivering an increased surface area and
reduced ground pressure. This enables Rexx
to operate in even the toughest of terrains,
including all pit environments and wet
underfoot conditions.

With its superior traction, gradeability and
narrow width – Rexx enables you to optimise
your mine design – from concept
to completion.

40% more fuel efficient

With patented on-demand power that lowers
fuel consumption, Rexx is up to 40% more
fuel efficient than its competitors, delivering
significant cost savings to miners, as well as
reduced greenhouse gas emissions.

Rexx’s empty-weight advantage means
less fuel is needed to move more of your
product.

Rexx’s design incorporates both durability
and lightness. At a loaded weight of 227
tonnes, Rexx’s 160-tonne payload represents
70% of gross vehicle mass. This weight
advantage maximises tonnes delivered
and drives big savings on fuel and related

emissions.

A second source of Rexx’s fuel efficiency
is its dual-engine design. During sections
of low power demand in a haul cycle, such
as the empty leg, Rexx can operate on one
engine, optimising fuel consumption.

Rexx is equipped with heavy duty road train
tyres which are smaller in size, and do not
experience tyre-heating issues to the same
extent.

With the power to haul directly from pit-to­plant over a much longer distance without
the need for the rehandle step – Rexx
delivers cost savings and a reduction in ore
loss/dilution at your site.

Driving better safety
in mine site haulage

The safety of our people, environment and
communities is our core value at Bis and we
are proud of our industry-leading safety record.
Rexx has a range of proprietary safety features
to keep operators safe.

Greater visibility for operators

With a large format front window and a cabin
that sits at the front of the profile, operators of
Rexx experience significantly greater visibility of
their surrounds.

Rexx is the single haulage solution that
solves the niche haul-distance equation
of mining projects – with the ability to
efficiently transport a 160-tonne payload
for 40km at a normal operating speed of
60km per hour.

This industry-leading distance is at least
four times further than conventional dump
trucks, which are limited in range due to
tyres heating.

3 REXX

Four times more range

While most standard heavy vehicles of this
scale would have extended blind spots in
front of their windshields of up to 6m, Rexx’s
unique window design enables operators
to see obstructions as close as 2.5m ahead.
Rexx’s cabin is compliant with FOPS and
ROPS.

360° Biscam view

With four on-board cameras, Rexx
operators have constant visibility of
all sides of the vehicle.

The camera system can be customised,
allowing operators to select the visual angles
best suited to their mirror setup and seating
position, resulting in a full 360° view of their
working environment.

Improved access and egress

Mining for the future

Bis has more than a century of operational
experience and has developed leading
monitoring and preventative maintenance
systems.

When compared with 6-7m access height and
standard ladder-style access for conventional
dump trucks – Rexx has really ‘stepped up’
the game – providing significantly-improved
access and egress for operators due to the
reduced cab height of just 2.4m from ground,
as well as pneumatically-controlled stairway
access to the cab.

Vehicle monitoring

All Rexx vehicles have a real-time in-cabin
monitoring solution installed. This includes
proprietary artificial intelligence and monitoring
systems that alert drivers and fleet managers to
non-compliant driving behaviour. This helps to
ensure adherence to your company’s guidelines
and policies, and drive safety improvement
initiatives.

Smaller mechanical components and tyres

Smaller machinery components reduce the
risk to safety. From hydraulic pumps and the
transmission engine, to the tyres that weigh
just 800kg – all the components of Rexx are
smaller than most, reducing the risks of injury
associated with changing and working with
large, heavy components.

We have embarked on a digital journey to
improve how we manage and deliver safely
throughout our operations.

Our assets are equipped with technology
features with an ability to improve safety in
both real-time and in the future, using data
analytics techniques.

Our technology suite is proactive, using
both Artificial Intelligence (AI) and human
data analytics to gain meaningful and
valuable insights.

This software will consolidate all of the above
data sources to create and develop insights
that alert managers and vehicle operators on
operational risks and issues in real-time.

Bis’ monitoring technology also captures
daily operational data to help identify
areas for improvement and drive business
efficiencies.

With Rexx’s intelligent in-cab systems, you
receive valuable information to optimise your
production and improve on-site operational
costs.

Rexx’s smart design has adequate space to
house automation hardware to align with
your site’s pathway to automation.

Rexx can be easily retrofitted for automation
with the inclusion of a broad range of sensors
to report on wheel stability, bin tipping,
suspension control and engine operation.
