performance and equipment durability. Once completed, the machine is painted and leaves the Haver Service Centre looking brand new. All refurbishments include a one-year warranty. For more extensive coverage, customers may opt into an asset management programme tailored to each operation that includes monthly, quarterly or yearly equipment audits by certified technicians, whose goal is to increase equipment lifespan. Engine rebuilds With commodity prices at historic lows in recent years, it has become popular for mining companies to overhaul essential equipment components. According to Cummins Southern Africa, a prominent engine manufacturer, there has been a significant increase in demand for critical rebuilds of high-horsepower engines as mining companies seek to optimise the lifecycles of their equipment. To meet the increasing demand, the engine maker embarked on a R5,4 million capital expansion programme in late 2015 to accommodate bigger engines such as the QSK78, which weighs in at 10,2 t, at its Master Rebuild Centre in Kelvin, Johannesburg, South Africa. It services the whole of southern Africa, including Botswana, Zambia, Mozambique, Namibia and Zimbabwe, covering mining and other high-horsepower applications. Since 2010, the company has noted increasing demand for rebuilding services for its high-horsepower range from the QSK 19 to QSK 78, according to Patrick Mohale, leader at Cummins SA’s Master Rebuild Centre. Cummins Southern Africa’s high- horsepower facility was established as part of the engine maker’s international strategy, announced in 2012, to increase high-horsepower engine remanufacturing capacity by 100% to meet demand for “a rapidly expanding population of mining equipment powered by its popular QSK and K-Series engines”. At the time, the engine maker said it would double total high-horsepower rebuild capacity to about 7 000 units per year by 2016, compared with the 2011 capacity of about 3 500. Cummins’ engine rebuild process is said to offer “as-new” reliability and life-to- overhaul, and also carries a new warranty of 12 months and unlimited hours. The high-horsepower range spans from 450 hp to 3 600 hp and encompasses engines with displacements of 19, 23, 30, 38, 45, 50, 60 and 78 litres. Increasing capacity Mohale says the 3 366 m² Cummins Master

To meet the increasing demand for engine rebuilds, Cummins embarked on a capital expansion programme to increase the capacity of its Master Rebuild Centre in Kelvin, Johannesburg, South Africa.

When buying rebuilt gear, it is of utmost significance to ascertain that the refurbished piece of equipment has a warranty and maintenance programme.

addition of a refurbishment programme to its breadth of services and equipment for the mining and aggregate industries. The new programme gives customers the opportunity to save as much as 40% over buying new, while having the assurance that their refurbished machines will operate at peak capacity. “As an industry leader, we offer our customers an array of services and upgrades to improve their equipment and add value to their process, which is why we added refurbishment to our circle of offerings,” says Karen Thompson, president of Haver & Boecker. Peter Kilmurray, vice president of Sales at Haver & Boecker, says the company has the capacity to update old screening equipment with all the bells and whistles of new technology, at nearly half the cost of purchasing a new machine.

As part of the programme, Haver & Boecker’s technicians inspect and document all critical components and parts on a vibrating screen onsite or at the new Haver Service Centre. Each customer then receives a complete report documenting the specialists’ recommendations. Technicians improve screening performance by implementing necessary upgrades using both new and re-engineered components. Refurbishments can take as little as one week to complete, depending on the scope of the work. They include everything from installing wear liners to replacing the shaft or adding an automatic lubrication system to extend bearing life. Following the refurbishment, Haver & Boecker tests the vibrating screens with Tyler’s Pulse vibration analysis service programme, which monitors the health of vibrating screens to ensure optimum screening
