A new automation system will improve
safety and productivity in underground
mines. Epiroc says its Scooptram
Automation Total, enabled by the Traffic
Management System, will improve safety
and productivity by creating a common
information environment that controls
multiple fleets of loaders.
The Traffic Management system
operates the fleet and eliminates the risk of
collisions in common drifts. The automation
area is fully isolated with safety barriers
that shuts off the system if personnel or
unauthorised vehicles accidently enter. It is
possible to bring new vehicles into the area
and add them to the Traffic Management
System without stopping the production,
using the check-in/check-out procedure.
"This is a great step forward in
our development of automation and
information management solutions.
Scooptram Automation Total will ensure
the safety for underground operators and
at the same time improve efficiency," says
Vladimir Sysoev, global product manager,
Automation.
Hitachi excavators cut emissions and fuel
consumption
Towards automation
Hitachi has released the first Hitachi 120t EX1200-7 excavator.
The first Hitachi 120t EX1200-7 excavator,
a new addition to the EX-7 Series, recently
arrived in South Africa, following its
launch earlier in the year at Bauma 2019 in
Germany.
The smallest machine in the EX-7
Series, the EX1200-7, comes in two
configurations - backhoe or shovel, and
packs a punch with a 4.5% increase in
bucket capacity, optimised swing control
and an upgraded hydraulic system,
including a flow-regeneration valve,
which means lower power requirements,
lower fuel consumption, and increased
pump life.
“Fuel efficiency was a major factor in
the design of the EX-7 Series because we

recognised the importance of caring for the
environment while remaining profitable.
These machines make this easier than
ever before,” says Hitachi Construction
Machinery (HCM) Africa’s marketing and
business development manager, Marius
Weber.
The electric-controlled main pump
and a hydraulic regeneration circuit add
to this latest line of machinery, reducing
fuel consumption by up to 10% in some
models, and also includes a linear-controlled
oil cooler and radiator fan clutch throughout
the EX-7 Series.
In addition, different engine options
are available, in particular the FCO (Fuel
Consumption Optimisation).
Cat’s new underground articulated dump
truck (AD45) meets the strictest emissions
standards. With a payload of 45 tonnes
(t), the new truck is a perfect three-pass
match to the Cat R1700 underground
loader. The new AD45 continues to
deliver the superior speed on grade of its
predecessor, the AD45B, and it has the
same dimensional envelope even when
configured for minimal exhaust emissions.
The AD45 is powered by the proven
and fuel-efficient Cat C18 engine. The
6-cylinder engine is turbocharged and air-
to-air aftercooled, and it produces 439 kW
(589 hp) in standard configuration and 447
kW (598 hp) in EU Stage V compliant form.
Using the proven Cat Clean Emissions
Module to limit both particulate matter and
NOx to near zero, the AD45 is certified to
meet EU Stage V (equivalent to US EPA
Tier 4) and is approved by CANMET for
use in underground mines. The module
uses selective catalytic reduction with
diesel exhaust fluid injection and a diesel
