INDUSTRY INTELLIGENCE
Rebuilding equipment makes economic
sense. When this work is carried out by
Original Equipment Manufacturers (OEMs),
the rebuild can incorporate the latest parts
and technology upgrades, ensuring that
the equipment provides the best possible
production during its second life.
Sandvik Mining and Rock Technology’s
Service Business line manager for
Southern Africa, David Hickson, says
the OEM rebuilds are much more than
simply stripping, sandblasting, lubing
and reassembling a machine with new
parts. Rather, today’s work is performed
with the primary objective of ensuring
the equipment’s performance during its
second life is as close as possible to its
design potential.
Sandvik’s rebuild programme offers
various solutions ranging from scoped
rebuilds where equipment is inspected by
certified specialists and work done in line
with the customer’s requirements; or more
advanced solutions where pre-engineered
kits are prepared in the Sandvik factory
and fitted to the machine to either return it
to its original condition, or to upgrade the
machine to the latest available technical
and safety specifications.
“Our life extension programmes
can be tailored to requirements using a
flexible, modular approach that depends
on the condition of the machine and the
systems that are required to be rebuilt,
or it may involve a full scope rebuild that
is completed at a fixed price. What the
customer opts for typically depends on
what endurance and productive capacity is

required from the machine’s second life,”
he says.
“A Sandvik full scope rebuild is covered
with the same warranty as a new machine,
giving customers complete peace-of-mind
around machine performance, reliability and
durability during the subsequent life. In this
way, we can prolong the economic lifespan
of a customer’s assets, giving them the
best possible return on investment and the
lowest total cost of production.”
“Experienced miners know that wear
and tear is unavoidable, and that critical
components and systems will deteriorate
over time, often undetected. If such wear
is not systematically eliminated, it will
inevitably result in excessive unplanned
machine downtime and unnecessary
collateral damage and cost. Identifying
the optimal rebuild interval and scheduling
rebuilds accordingly is a strategically smart
approach – you preserve productivity,
extend operational life and reduce running
costs. In one intervention, a full rebuild will
remove all unknown risk from the machine
and will significantly improve the reliability
and operating cost,” says Hickson.
Sandvik has rebuild offerings for all its
major products – underground drill rigs and
bolters; underground loaders and trucks;
mechanical cutting machines; surface drill
rigs, and crushers.
Bio chisel paste prolongs the life of hydraulic breakers
www.equipmentandhire.co.za
As part of Epiroc’s aim to help protect
the environment, all new Epiroc hydraulic
breakers are now delivered with Epiroc
Bio Chisel paste. The formulation is
approved by the European commission
for use in environmentally sensitive
applications.
Used to grease the wear bushings in the
breakers, Epiroc Bio Chisel paste is based
on special synthetic esters that are easily
biodegradable. The paste helps prevent
bushing wear and prolong working tool life.
Inside a hydraulic breaker, the ambient
working temperature reaches up to 1 100°C
under extreme load. In these conditions the
standard greases available on the market
will liquefy and disappear.
Tailor-made for hydraulic breakers,
Epiroc Bio Chisel paste gives excellent
performance across a wide range of
temperatures, from –30°C up to
1 100°C. The paste has high load carrying
characteristics with very good separation
capacity. It helps lower breaker operating
costs by reducing bushing wear and
working tool breakage. High water
resistance makes Epiroc Bio Chisel paste
suitable for underwater applications, and
the paste offers a high level of corrosion
protection.
Epiroc hydraulic breakers are now delivered with Epiroc Bio Chisel paste.
