CASAR has always been
known for the extraordinary
performance of its
mining ropes. Now they
have set a new world record in
Australia’s Northparkes mine,
establishing a new milestone
in the process. After 652,239
completed cycles, a service life
of 46 months and more than 22
million tons of moved rock, the
Turboplast M used for the work
was gracefully retired. The rope
was discarded according to plan
in mid-January 2015 under the
supervision of Roger Smith, an
experienced expert for hightech
mining ropes in the service
of CASAR, and Alexander Fäh,
sales engineer for mining ropes.
The Northparkes mine is located
in a rural area of the state of New
South Wales, around 450 km
to the west of Sydney. At the
end of 2013, the Chinese company
China Molybdenum Co.,
Ltd. took over 80 % of the shares of the Rio Tinto Group, while the remaining
20 % are still owned by the Japanese
Sumitomo Group. Gold and high-quality copper
concentrate are mined and extracted in the
Northparkes mine. The hoisting machine is a
ground mounted friction winder with a motor
power of 3 MW which transports a
maximum payload of 16.5 t at a
speed of 15.3 m/s from a depth
of 590 m to the top. Four
hoist ropes with a diameter
of 32 mm and
a length of 750 m
are used, two ropes
right hand Lang’s lay
and two ropes left hand
Lang’s lay.
