Sandvik Mining and Rock Technology has launched the Ranger DX900i drill rig in Australia.
The original equipment manufacturer’s (OEMs) latest top hammer surface drill rig was introduced globally last October. The first DX900i arrived in Australia this month and was officially unveiled at an event hosted by Sandvik at its Dandenong premises last week.
Ranger DX900i has been designed to provide the widest drilling coverage in its class, with a revolving upper structure offering a 290-degree drilling reach and 55-square-metre coverage, saving time and minimising the need to reposition the rig.
Sandvik surface drilling and exploration business line manager, Scott Wright, said the DX900i was suited for drilling conditions across Australia’s major gold mining regions, such as the Goldfields in Western Australia.
“In the Goldfields around Kalgoorlie there are a lot of (Sandvik) DP1100i and DP1500i drill rigs, so the DX900i will fit in with them for smaller holes around the 89mm or 102mm mark — that’s the sweet spot for it,” Wright told Australian Mining.
“The DX900i is similar to the DP1100i rock drill. There is quite a lot of interest from mining customers because it is basically very similar in terms of capability.”
Despite the rig’s ability to rotate, the DX900i has been designed to maintain maximum stability through a counterweight structure opposite the boom. A low centre of gravity and high tramming power allow it to remain extremely mobile.
To add drilling efficiency, Sandvik has included 21–27kW of power and a new range of GT60 rock tool, enabling straighter drilling of 92–127mm holes.
Sandvik has designed the machine’s iCab for improved operator ergonomics and to minimise noise levels. The cabin’s new user interface has been developed based on customer feedback and includes new ergonomic joysticks for ease of tramming.
Cabin noise levels have been reduced to 73.5 decibels, while a climate system regulates and maintains air conditioning levels, according to Sandvik.
The new Ranger series is equipped with the latest versions of Sandvik intelligence, including full hole automatics, troubleshooting functions, iTorque drilling control system, full radio remote control and optional extras available for hole navigation, on-board data collection, wireless data transfer and drill plan creation and analytics.
Local contractor Maxfield Drilling is the operator of Australia’s first DX900i drill rig and plans to put the machine into the field immediately.
