TEN TON TWINS BREAK GROUND at Northern Cape Mine

O ne of Atlas Copco Construction Technique’s longstanding mining customers recently ordered two HB 10 000 10 t hydraulic breakers to increase productivity at its Northern Cape open-cast mining operation. The mine which produces iron ore/various grades of manganese ore has been a key account for Atlas Copco for over 15 years. Impressed with the high performance and durability of the five Atlas Copco HB 7000 7 t hydraulic breakers that have been in operation at the site for over a decade, the mine ordered two HB 5800 (5 t) units to meet its surface mining applications, including rock breaking after blasting as well as secondary breaking and crushing of rocks before the material moves into feeders. According to Atlas Copco Construction Technique Area Sales Manager, Amanda Roets, the superior efficiency, excellent performance and unmatched reliability of these heavy hydraulic breakers contribute

ergyRecovery system automatically util- ising the piston recoil energy to increase performance without additional hydraulic input and to lower vibrations, making the job easier and more efficient. The hydrau- lic breakers are suitable for a wide range of carriers including wheeled and crawler excavators; 120 ton excavators are recom- mended for the HB 10 000. Atlas Copco Construction Tools are cer- tified according to ISO 9001:2008, ISO 14001:2004, and OHSAS18001:2007. “Our hydraulic breakers conform to the provisions of EC Directive 2006/42/EC (Machinery Directive) and 2000/14/EC (Noise Directive),” says Roets. Atlas Copco transformed the construction and mining industries when it first intro- duced the innovative hydraulic breakers more than five decades ago. With end-user productivity and total cost of ownership top of mind, Atlas Copco has continued to re- fine these breakers to deliver on its brand promise of Sustainable Productivity.

to increased productivity and improved production on the mine. “In addition, fea- tures such as low noise and vibration levels which enhance operator safety and comfort, and the fact that they have a low impact on the environment, played a fun- damental role in the mine’s decision to or- der the two 10 tonners,” says Roets. “With these two heavy weights, which are the first 10 t hydraulic breakers Atlas Copco has supplied in South Africa, a total of nine hydraulic breakers is currently operating at the iron-ore mine. The 10 t breakers’ larger tool diameter cre- ates a bigger footprint and the units have a larger handling capacity and deliver a more powerful hit rate, meeting the mine’s re- quirement for improved productivity. The powerful HB range has an operating pressure of between 160 and 180 and a maximum hydraulic input power of 159 kW. “Our HB range features an automatic start/ stop function for convenience and safety,” explains Roets. The breakers have an En-
