MINE HOISTS
Assembly of a SIEMAG TECBERG Koepe hoisting machine on test benches at TECBERG park for further system test and system integration
refractory products and chromium compounds in the chemical industry .
The existing Donskoy Ore Mining and Processing Plant ( DGOK ) complex was established in 1938 in the town of Khromtau in the Aktobe region of mid-western Kazakhstan , approximately 700 km from the Caspian Sea . According to the company , the volume of confirmed chrome ore reserves is the second largest in the world and the quality of the chrome ore meets the highest quality standards . The Donskoy Ore Mining and Processing Plant employs a total of 7,500 people . The contract requires SIEMAG TECBERG to engineer , produce , deliver , install and commission the following equipment : n Two 4-rope Koepe hoisting machines ( slide bearings ) in tower arrangement , each with an electric drive power of 5.3 MW for a maximum annual output of 9.75 Mt , including hydraulic braking systems and automation and signalling technology , designed in part to meet the very high international safety requirements of the SIL standard ( Safety Integrity Level ) n Eight deflection sheaves to regulate a controlled rope run n Special equipment , accessories , spare parts Both hoisting machines are designed as a skip / skip system for a considerable shaft depth of 1,487 m . “ The design of the main shafts together with the plain bearings ensures a largely wear-free operation and the greatest possible availability of the two hoisting machines – both key arguments in favour of SIEMAG TECBERG . The design based on the SIL standard offers the operator and his employees a very high level of safety , which is also a very important criterion in the selection of suppliers .”
For SIEMAG TECBERG this first order for a new customer from Kazakhstan it says “ once again
Germany ’ which has once again prevailed
against global competitors and especially
against emerging manufacturers from China and
Russia . The respective governments of those
important primary producing countries exercise
massive influence to localise the technology
production for their own construction of
industrial plants .”
“ The continuous development of product
innovations combined with the system
integration of mechanics , hydraulics ,
automation , drive and signalling technology
under the same roof is the unique selling point
of SIEMAG TECBERG and this has led to the
leading market position ,” says Jürgen Peschke ,
Managing Partner of the SIEMAG TECBERG Group .
confirms the company ‘ s performance promise .

UZTM-KARTEX continues dominance in Russia
Ural Mining Metallurgical Company ( UMMC ), one of the top Russian producers of copper , zinc and other precious metals is equipping copper-zinc miner Uchalinsky GOK , one of its key mining enterprises , with a set of mine-hoisting equipment designed by Russian manufacturers . By November 2021 , Uralmashplant JSC ( part of the UZTM-KARTEX Group ) will supply the mining complex with three mine hoists machines for construction and operation of the new Skipo- Kletevaya mine which is exploiting the Novo- Uchalinsky deposit .
