A drill designed for drillers

RTDrill has unveiled its latest down the hole (DTH) hammer drill rig, the RTD32, which is now available across Australia through CRAM.

The latest in the range of RTDrill’s surface crawler drill rigs is suitable for drilling diameters of 105 to 203 millimetres and a net drilling depth of 40 metres.

With 403kW engine options in the Tier III and Tier IV models, the RTD32 features a 1000 CFM compressor.

“The new RTD32 combines the efficiency, safety and functionality of the DTH drill rig in its class, combined with an affordable price tag,” says William Rogers, CRAM’s national product manager – surface mining equipment.

“A compact design with 12.55 metres length and 2.5 metres width makes the RTD32 a cost-effective model in terms of operation, transport and maintenance costs.”

The RTD32’s engineered safety controls include a falling object protective structure (FOPS) and a rollover protection system (ROPS) built to European standards. Two emergency stop buttons, one on the drill carriage and another on the control panel, allow immediate engine shutdown and compressor depressurisation. The cab is also equipped with a reversing camera and designed ergonomically for maximum driller comfort and safety, with the option for full MDG15 compliance from the factory.

The drill features a tilting and slewing system mechanism that allows operators to drill in all directions, even horizontally if necessary. The crawler can move at speeds up to 1.9 to 2.62 kilometres per hour and has up to 60 per cent gradeability.

Part of the Motion Asia Pacific business portfolio, CRAM specialises in fluid power, electro-hydraulic engineering and design, undercarriages and specialised maintenance and engineering services.

From multiple service centres across all states, CRAM offers full maintenance support for RTDrill products, facilitating maintenance, refurbishment, repairs and overhauls throughout the entire life cycle of the equipment.

“Our technical team can assist customers with drill rig component supply and service, as well as customisations and adding new machine options. Our clients benefit from access to factory level pricing supported by comprehensive inventory, workshop and site service capabilities,” Rogers says.
