HIGHEST RELIABILITYBy rethinking the hydraulic and electric designs, the DR460 is engineered for reliability. Following the most stringentAustralian standards, hard piping is used whenever possible and the remaining hydraulic hoses are well routed and secured.Valves are located close to the point of use, eliminating component build-up in any single location. Electric cables areseparated and shielded to reduce hazards. Traditional layouts are cheaper up-front, but the DR460 design assures properinstallation, reduces chafing, and allows for quick trouble shooting and repairs. Service access and security are clearlyimproved with the full perimeter walkway. Reliability and serviceability translate into continuous performance with loweroperating costs and higher mechanical availability.

MOST TONNES DRILLEDProductivity comes down to effective drilling time and instantaneous penetration rate. The former results from highavailability, quick tramming, setup, and hole spotting, and effective pipe handling. With 12,8 m (42 ft) long multi-pass pipes

or the 16,8 m (55 ft) long single-pass pipe, less time is lost adding and racking pipe. Instantaneous penetration rate dependson pulldown, rotation speed, and hole cleaning, as well as the operators ability to fine tune the drilling parameters.
