MINE HOISTS
TURBOLITE ® M, a new 8-strand compacted hybrid
hoist rope for underground mining. “TURBOLITE ®
M delivers the best strength-to-weight ratio in the
industry and is measurably lighter than standard
steel ropes. Its high-strength plastic impregnated
fibre core is fatigue-resistant and makes
installation and rope maintenance easier.”
“In extensive field-testing, TURBOLITE M ropes
have been in service four years in an
underground vertical shaft used on a drum
winder. These ropes still have significant life
remaining, and are approaching three times the
normal service life of flattened strand ropes.
Higher strength, lighter weight TURBOLITE M
ropes provide top performance and service life,
minimising downtime and lowering the overall
cost of ownership.”

The industry-leading SOBO iQ braking controller
combines cutting-edge technologies to provide
significant flexibility, safety and durability on
applications including mine hoists. The controller
features three-state digital modulation and a
revolutionary dual-loop PI control
(pressure/speed). The pressure control is based
not only on speed but also on deceleration.

specialised hydraulic power units are engineered
to perform in tough mining applications.
Synthetic mine ropes on the horizon
Global leader in the supply of mining
ropes, Bridon-Bekaert, recently said that it
and Applied Fiber are combining their expertise
to develop and bring to the market advanced
solutions to improve efficiency and safety in
heavy industrial operations including mining.
“During the last decade, high performance
synthetic fibre materials are playing an important
role in new rope product developments. Within
heavy industrial applications in particular, these
lightweight materials can provide compelling
improvements to operational efficiency and
workforce safety. Both heavy equipment and
operations stand to benefit from specific
advantages of synthetic fibre, however
terminations on large and critical ropes have
historically been a conversion barrier. Combining
advanced fibre rope and termination expertise
accelerates the rate of advancement towards
high performance termination solutions.”
Bridon-Bekaert said its long standing steel
and synthetic ropes expertise, and “profound
application knowledge” combined with the
“termination excellence of Applied Fiber” are “a

recipe for success to address the industry
challenges of customers worldwide.”
“Bridon-Bekaert is pleased to announce our
companies will be working together. This
collaboration fits perfectly in our mission to be
the leading innovator, developer and producer of
the best performing ropes and advanced cords
globally. Providing terminated fibre rope
solutions for high impact and performance driven
applications complements our steel, synthetic
and hybrid rope solution offerings to our
customers,” said Brett Simpson, CEO of Bridon-
Bekaert
“Terminated fibre ropes using Applied Fiber’s
leading technology opens new options for high
performance synthetic rope. In some cases the
synthetic offering may retrofit directly into
existing steel wire applications and provide key
performance benefits. The use of Applied Fiber’s
developed and proven termination technology
also addresses the historical construction
limitations on the fibre rope itself. Given the lack
of end-connection options, typical fibre ropes are
designed around the limits of splice-able
connection. Terminated fiber ropes, engineered
together, opens many new performance options.”

Teufelberger-Redaelli told IM that over the last
six years it has very successfully tested its new
High Performance Hoist Rope for drum
winders. The 7Mine was
tested on several

The 7Mine rope has been successfully tested on
several multi-layer drum winders in South Africa
and Canada
winders in South Africa and Canada. “In all cases
the new 7Mine hoist rope was able to
significantly outperform the previously used
triangular strand ropes in terms rope service life.
Additionally the rope showed a lot less torque
and an improved rope stretch characteristic
compare to triangular strand ropes.”
So far, the deepest shaft equipped with a
7Mine was in South Africa with a depth of around
2,300 m. The two ropes supplied were 54 mm in
diameter and had a length of 2,700 m each.
Teufelberger-Redaelli says it developed this new
high performance rope to replace triangular
strand ropes without any downsides in terms of
rope weight and breaking
strength. “The rope will
help mines to improve the
productivity of their existing
systems by using a modern
state of the art high
performance hoist rope.”
Based on the “extremely
positive” field-tests
Teufelberger-Redaelli says it
is convinced that it has now
a high performance rope it its mining portfolio
which can be used in the deepest mines on earth
without negatively affecting the existing system. IM
