ROC P55 – A Star for Bauma China 2008


Nov 2008, Shanghai, China

ROC P55 – Atlas Copco to launch new heavy duty pneumatic crawler at Bauma China. The upcoming Bauma China exhibition to be held  in Shanghai (Nov 25-28) will see the launch of the new ROC P55 drill rig from Atlas Copco as one of the star attractions.

This small, one-man operated, heavy duty crawler is designed to drill holes in the 92-140 mm (3 5/8"–5 1/2") diameter range in limestone and aggregate quarrying, surface mining and construction. It is a powerful, robust and stable rig which can consistently drill straight holes, even in fissured rock, giving the highest possible productivity at the lowest possible running cost.
The stability of the rig is a key factor, allowing the driller to use 3-5-inch DTH-hammers, depending on hole size. Atlas Copco hammers are among the fastest on the market and are well known for their speed, reliability and longevity. With its high penetration rates and low fuel consumption per meter drilled, the ROC P55 has a direct impact on profitability.
Furthermore, the rigid pipe string is highly resistant to bending and leaves very little space between the pipe and the holes wall. Together with the optimally adjusted feed force, hole deviation is kept to a minimum. This enables the burden and spacing to be increased, thus reducing overall drill and blast costs.
The rig is also extremely easy and comfortable to use. The hydraulic system, centrally driven by a steady air motor enables smooth setup. Powerful air tramming motors with a force of 45kN (9 664lbf) give fast tramming. In addition, the operating panels are ergonomically designed and user-friendly with the drilling controls located directly at the feed and tramming and boom positioning controlled from a swing-arm panel.
Energy losses are minimal and the impact force is delivered directly to the bit, without having to pass through the drill string. This gives constant penetration, independent of hole depth, and much better performance when drilling in fissured rock.
The robust power pack – which is tuned for maximum efficiency – has plenty of excess capacity for those tough jobs that can test a drill rig to the limit. This, in combination with the fast COP DTH rock drills, enable the ROC P55 to give superior performance even when drilling deep, large diameter holes.
Additional features that impact the operator’s working environment as well as the life of the equipment are; the well-positioned, hydraulically elevated tube rack which simplifies the adding and removal of drill tubes, the swing-arm control panel which enables the operator to safely control the drilling in any feed in any position, from vertical to horizontal, excellent overall visibility and the market’s best dust handling system.
