Osborn equipment for Williamson mine
Torre Industries is adding Elephant Lifting
Equipment to the Plant and Equipment
Division of its group of companies, along with
SA French, Manhand and Kanu Equipment.
The ultimate aim is to combine SA French
and Elephant Lifting Equipment under the
umbrella brand ‘Torre Heavy Lifting’ which,
combined with the extensive distribution
network of the Torre group, will allow Torre to
offer a total lifting solution from consumables
to tower cranes to its customers across Africa.
Elephant Lifting Equipment is head-
quartered in Centurion and has branches in
Durban and Pemba, Mozambique, as well
as a manufacturing facility in Pretoria West.
Its products include EOT cranes, monorails,
electric chain hoists, chain and lever blocks,
winches and wire rope pulling machines, lift-
ing and spreader beams, mechanical grabs
and clamps, slings (chain, polyester and steel
wire rope), shackles and rigging accessories.
“For every tower crane we supply, new
or used, there is probably another 20 %
of the total value of the crane that we can
offer in add-on services,” Quentin Van Breda,
Managing Director, SA French, says. “The
acquisition will allow us to offer a genuine
one-stop shop for tower cranes, from slings to
shackles, concrete buckets and pallet forks, for
example. We can now even offer foundation
bolts and spreader beams in-house.”

Torre acquires Elephant Lifting Equipment
An R8-million export order for two
Osborn Telsmith 36 x 48 single
toggle jaw crushers and an apron
feeder – to be employed at Petra
Diamonds’ Williamson mine in
Tanzania – has been awarded to
Osborn.
This is the latest in a series of
orders that the Johannesburg-
based manufacturer has received
from Petra Diamonds. Osborn’s Chris Slade
elaborates: “Osborn already has jaw crushers
and apron feeders in this application at Petra
operations in South Africa, and these have
proved themselves over the years. Osborn has
also previously supplied an apron feeder to
the Williamson mine in Tanzania’s Shinyanga
Province. This latest order reflects our cli-
ent’s confidence in our products’ quality and
performance.”
Other Petra Diamonds mines where
Osborn equipment has been operating suc-
cessfully for many years include Koffiefontein,
Finsch and Kimberley.
Petra’s new Osborn Telsmith jaw crushers
form part of an expansion project aimed at
increasing Williamson’s production capacity
from 188 465 carats per annum (ct/a) in the
2014 financial year (FY) to approximately
300 000 ct/a by FY 2017.
At 146 hectares in size, Williamson is the
world’s largest economic kimberlite by surface
area. It is Tanzania’s only important diamond
producer and, despite having been operated
continuously since 1940, the pit is just 90 m
at its deepest point due to the vast size of
the deposit. The Mwadui kimberlite pipe, on
which the Williamson mine is based, contains
a substantial diamond resource of approxi-
mately 33,1 million carats.
The scope of Osborn’s contract includes
manufacturing and supplying Williamson’s
new jaw crushers, as well as supervising their
installation and commissioning.
Outlining the benefits of Osborn’s single
toggle crushers, Slade notes that they are
designed for a high capacity throughput
due to the elliptical movement of the swing
jaw, which also assists in the discharge of the
crushed material.
“As the single toggle crushers will achieve
far higher capacities than the double toggle
design, they are often used as primary crush-
ers,” he says. “The Osborn Telsmith single
toggle jaw crushers offer a production capac-
ity up to 1 000 t/h and boast rock compressive
strength up to 500 MPa. They feature a pat-
ented hydraulic beam locking system and
excellent nip angle, with reversible jaw dies,
for maximum wear.”
