efficiency even further, while ensuring
maximum stability during idling for
smooth operation. Variable working
modes include heavy-duty, standard,
light-duty, and break, which enhance the
versatility of the excavator in different
working environments.
Additional ‘smart’ features include an
advanced GPRS monitoring system and
machine alerts to allow for proactive
monitoring of engine hours, fuel usage,
and location history. The upgraded
undercarriage has a unique X-shape
structure in terms of its lateral beams
for extra strength and rigidity,
excellent torsion, and bending-
resistant performance.
The 21t SANY SY210C-9 excavator from
Goscor Earth Moving (GEM), part of the
Goscor Group, offers a high level of
efficiency and productivity demanded by
arduous applications such as mining. The
SANY SY210C-9 features a six-cylinder
in-line water-cooled Cummins
6BT5.9-C140 engine, with a rated engine
power of 140hp at 2 000rpm, and a
maximum torque of 571Nm at 1 300rpm.
The engine is matched perfectly to the
hydraulic system, thanks to the
proprietary Dynamic Optimisation
Matching Control System (DOMCS),
developed by SANY.

Sandvik’s safe, dependable blast-hole drilling
and built to guarantee reliability while
bringing safety and productivity to any
operation. The DR412i is designed for a
hole range of 216–311mm, with high- and
low-pressure versions available and with a
multi-pass maximum hole depth of 75m.
The Sandvik DR412i has several
features that work to protect operators
and maintenance employees through its
emphasis on creating space for accessibility
and visibility, which starts at the operator’s
cab and extends to work areas and
routine maintenance ports. Work areas
are optimised to serve productivity, with
the entire layout of the rig optimised for
ergonomic functionality and safety in line
with worldwide standards and guidelines,
including mining design guidelines and
earth-moving equipment safety round
table (EMESRT).
Sandvik Mining and Rock Technology
has delivered and commissioned the first
DR461i (now identified as the DR412i)
rotary blast-hole drill to the African
continent. This blast-hole drill improves
productivity while returning improved
fuel efficiency and availability compared
with its predecessors.
The Sandvik DR412i is focused on the
changing requirements of surface miners
and designed to improve conservation
and deliver dependable penetration in
the world’s harshest mining conditions.

When planning and
implementing load-haul mining
contracts, the importance of
close cooperation between
contractor and customer cannot
be over-emphasised, says Graeme
Campbell, commercial and
operations manager of Raubex
Group company SPH Kundalila.
“It begins with the customer
providing relevant and accurate
data so that the contractor can
make the right calculations, but it
goes much further than this,” says
Campbell. “When both parties
are focused on improving cycle
times, the project efficiency can
be significantly improved, and the
cost reduced.”
He highlights that contractors
will not be able to achieve the
required cycle times if the
customer causes any delays. But,
on the other hand, it only takes
small improvements to shorten
cycle times and reduce the cost
per tonne. This result should
provide enough motivation for a
constructive partnership.
“There are basic principles of
earth moving that influence cycle
times, and these include ensuring
ideal conditions both on site and
off site,” he says. “On site, the

loading area should be level and stable underfoot, while the
haul road needs to be a well-maintained, quality surface
with as few stops as possible.”
The offload area should also be easy to access, as this
contributes to a quick turnaround time, Campbell emphasises.
