MINE HOISTS
SIBRE braking solution for Mopani
Mopani Copper mines PLC is an integrated copper and cobalt producer owned by Carlisa
Investments, a JV in Zambia between Glencore, First Quantum and ZCCM Investment Holdings.
Mopani is the largest copper mine in Zambia and recently announced a new $320 million shaft and
associated infrastructure to be constructed at its Synclinorium project. The new shaft will
significantly boost production and extend operations well beyond the current depletion rates. South
Africa’s Atlanta Winches SA is specialised in the design and manufacture of speciality winches and
hoists and has itself contracted SIBRE to equip the FLSmidth Blair Multi-Rope (BMR) 5.5 m by 1.5 m
production hoist (incorporating four drums) with a braking system. SIBRE is delivering six SHI 202
FC fail-safe floating calliper disc brakes. This are spring applied and hydraulically released. When
the brake is set with an air gap of 1.5 mm and braking on a disc with a diameter of 5,100 mm and a
thickness of 30 mm, one SHI 202 FC brake will produce a maximum braking torque of 398 KNm and
six of these brakes can produe a maximum braking torque of 1,593 KNm. The brake pads are lined
with sinter linings and are powered by a SIBRE self contained hydraulic power pack of type HPP V3
C. The order also includes two fail-safe disc brakes with EMG electro-hydraulic thrustor.
SIBRE operates a machining facility in Haiger, Germany with the assembly plant in Eschenburg.
Both facilities have seen significant modernisation and expansion to accommodate the demand for
highly engineered integral products. Since 2018 several new lines have been installed. The central
production plant in Haiger has several state-of-the-art CNC machines. These additions allow for
tighter control of production and faster response times to customer requirements.
purpose hoists, all specifically for the mining
industry.”
One of the recent projects entailed a double
drum clutchable hoist system for a shaft project in
USA complete with VFD, controls, E-house and
MCC, and amalgamating a complete set of
sheaves, stage winders, mine rescue system, and
mucking winches. In addition, Timberland recently
provided upgraded SIL2 VFDs and controls to a
project in Mongolia to provide the greatest safety
rating for the remote mine location.
The company adds: “We are very much an
engineering oriented company and we currently
have several professional engineers on staff
overseeing our team of technologists in our
80,000 ft 2 Woodstock facility. In addition, we have
an experienced in-house controls team to ensure
the outmost reliability. Timberland brings two very
significant advantages to all projects. First, 70 plus
years of experience dedicated to designing and
manufacturing hoists. Secondly, estimating, sales,
engineering, project management, procurement,
manufacturing, testing, commissioning and
service are all handled out of one building. Our
owner, managers and chief engineer are all close
proximity of manufacturing, which ensures control
over the project.”
framework of this project, the company is
constructing the Talitsky Mining and Processing
Combine (Talitsky GOK) and is carrying out a
significant amount of work on the sinking of skip
and cage shafts, the construction of the mine and
related infrastructure. The capacity of the new
mining and processing combine will be 2 Mt of
potassium chloride per year. Talizkij GOK is
scheduled to come on stream in 2023 and reach
design capacity in 2026.
SIEMAG TECBERG says that this contract
represents a logical continuation of the longstanding
partnership between the companies,
which began as early as 2014 with the award of
the contract for the preparation of project
documentation. For the skip shaft No. 1 (raw
material sylvinite) with a depth of 413 m and a
planned capacity of 2,400 t/h it includes two
double-drum skip shaft hoisting systems (No. 1
South and No. 2 North) and a single-drum cage
auxiliary drive system. For the shaft No. 2 with
cage hoist for personnel and equipment with a
depth of 362.5 m it includes a 4-rope surface
Koepe shaft hoisting system with Ø 4.0 m. Further
equipment includes skip loading facilities, devices
for rope laying and rope changing for the cage
shaft 2 and required spare parts and
documentation. The equipment will be delivered

major Russian potash project
In October 2019, the contract for the supply of
shaft hoisting systems was signed in Moscow
between JSC Verkhnekamsk Potash Company and
SIEMAG TECBERG GmbH. Verkhnekamsk Potash
Company is implementing a strategic project of
ACRON Group to create its own potassium raw
