Atlas Copco’s semi-hydraulic surface drill rig AirROC D45 SH, which is produced in China, has been successfully introduced at limestone mines and aggregate quarries across the country.
Since the beginning of the year, the rig has proven to be a popular choice with a steadily increasing number of customers.
The first unit in this series is used by the drilling contractor Liang Yalin Company, operating in the Liu zhi district of Gui zhou province. Yalin says the rig is meeting expectations and adds: “Compared to the local brands in China, this rig works faster and is more reliable.”
York Yang, Atlas Copco’s Product Manager in Nanjing, explains: “This is our first semi-hydraulic rig series and it represents a new concept compared with purely pneumatic drill rigs, focusing on maximum performance, high fuel efficiency and low initial investment. Right now it is intended only for China but we are investing in the worldwide potential.”
Designed to drill 92-127 mm holes to a maximum depth of 35 m, the AirROC D45 SH rig’s low fuel consumption and high penetration rate is thanks to a combination of Atlas Copco’s reputable portable compressor and DTH hammer, coupled with the reliable hydraulic control system.
Ergonomically designed to give the operator a comfortable working environment, the rig offers good visibility and serviceability and has controls at the rear as well as at the side, enabling the operator to stand on the rig while tramming.
