- OZ Minerals will install a production hoist (winder) which can carry nearly 40,000kg of ore to the surface
- The hoist system will have the highest available levels of safety through ABB Ability™ Safety Plus for hoists, the first fully SIL 3 certified suite of solutions for hoists
- Contract is part of a $400 million shaft expansion at the mining company’s Prominent Hill mine in South Australia
ABB has won a large order for its highest payload Koepe production hoist, associated infrastructure, and safety systems from Australian mining company OZ Minerals. The contract will help to ensure efficient processing performance and a long service life as part of an ongoing $400 million expansion at the Prominent Hill mine in South Australia.
The hoist, which will be designed and supplied by ABB, has a capacity of 39,400kg and the strongest drivetrain that ABB has ever installed in Australia. ABB specialists will also supervise installation and commissioning.
OZ Minerals’ gold, silver and copper mine began operations in 2009 as an open pit mine, but it is now an underground mine producing 4.5 million tons per annum, moving to between 4.5 and 5 million tons per annum from 2022 via a trucking operation. The hoisting shaft provides access to mineral resource outside the current trucking mine plan that would have been uneconomical via a trucking operation from around 2033.

Installing the Wira shaft will increase the annual underground mining rate, extend the mine life, reduce operating costs, lower emissions intensity, and reduce overall operational risk, according to OZ Minerals.
ABB is known as a global leader in hoist systems with the last four mine hoists installed in Australia awarded to the global technology leader. “The project is important for the country’s mining industry and metals security,” said Stuart Cowie, Head of Process Industries, ABB Australia. “The local supply chain and workforce also relies on the mine and at ABB we’re enabling it to continue for several more years with increased safety, higher production rates and lower emissions.”
Once operational, the installation at Prominent Hill will have ABB Ability™ Safety Plus for hoists, a suite of mine hoist safety products that brings the highest level of personnel and equipment safety available to the mining industry. It is the first fully SIL 3 (Safety Integrity Level) certified suite of solutions for hoists, rigorously examined and certified by an independent global functional safety certifying body, and strictly developed in accordance with the International “Safety of Machinery” standard IEC62061. The products include Safety Plus Hoist Monitor (SPHM), Safety Plus Hoist Protector (SPHP) and Safety Plus Brake System (SPBS) including Safety Brake Hydraulics (SBH).
