Fast-Fit Conversion Kit of Atlas Copco RD22U in Australia

Australian mining contractors operating multi-fleet drill programs across Western Australia's Pilbara iron ore country and the Eastern Goldfields gold operations face an equipment reality that European and North American markets rarely encounter at the same scale: the same drill rig is expected to service multiple mine sites with different carrier types, different thread system requirements, and different hole diameter programs over its operating life. The RD22U fast-fit conversion kit makes this cross-site flexibility practical—allowing the drifter to be reconfigured for a different thread system or shank interface specification within a single maintenance shift rather than requiring a drifter exchange.

The conversion kit contains the component set required to change the RD22U's front end configuration: the flushing head, the guide bushing, the shank adapter specification, and the front housing O-ring set. Changing from a T45 thread system program at one site to a T51 program at another requires all four of these components in the matched dimensions for the new thread class. The kit format provides all four from a single dimensional reference, ensuring the new configuration assembles with correct clearances rather than the mix-matched tolerance stack-up that results from sourcing components from different suppliers.

RD22U Conversion Kit Configurations for Australian Programs

Australian mining contractors with two or three active programs on different sites have found that maintaining one RD22U conversion kit per drifter in the parts inventory—rather than stocking a second drifter for the alternative program—saves approximately AUD 85,000–120,000 per fleet pair in capital equipment cost. The conversion takes half a shift; the spare drifter costs six months of operating budget. HOVOO supplies RD22U fast-fit conversion kits for Australian thread system and interface configurations.
