    Sandvik Leopard DI650i record hours: maintenance planning notes for mines

    Sandvik Leopard DI650i record hours: maintenance planning notes for mines

    First reported on Australian Mining

    30 Second Briefing

    Sandvik’s Leopard DI650i drill rig, operated by SRG Global, has set a global record with its rotary head, compressor and hydraulic pumps each reaching 25,000 uninterrupted operating hours before first major overhaul. The rebuilt rig’s engine also exceeded this threshold, signalling unusually low wear rates for high‑load components in production drilling. For mine planners and maintenance teams, the data point supports extended component life assumptions and potentially longer planned maintenance intervals on similar DI650i fleets.

    Technical Brief

    • Rotary head, compressor and hydraulic pumps all reached overhaul point without unplanned component changeouts or rebuilds.
    • Component life was achieved on a single rig, simplifying traceability of operating hours and maintenance history.
    • Rebuild was conducted jointly, implying OEM-level inspection of wear mechanisms.
    • Engine surpassing the same hours suggests fuel, filtration and cooling systems maintained design performance over lifecycle.
    • Extended run to first overhaul reduces cumulative downtime windows for major component changeouts across a fleet.
    • Data from this rig offers a calibration point for life-of-mine maintenance cost models on similar fleets.

    Our Take

    The related June 17 piece on the same Leopard DI650i shows 25,000 hours to first major rebuild on key components, which in our database is at the upper end of surface DTH rig utilisation and signals strong lifecycle economics for Australian contractors like SRG Global.

    With tungsten and tungsten carbide input costs highlighted as rising in the June 15 drilling-consumables article, extended operating hours on the Leopard DI650i imply that drill fleet owners in Australia can partly offset consumable price pressure through higher component life and reduced unplanned downtime.

    CITIC HIC semi-mobile crusher at Duobaoshan: design and throughput notes for mine planners

    A PSZ3000-B semi-mobile gyratory crushing station, independently designed and built by CITIC Heavy Industries in Luoyang, has completed no-load and load commissioning at Zijin Mining’s Phase II expansion of the Duobaoshan copper-molybdenum mine in Heilongjiang, with all performance indicators meeting design standards. The semi-mobile unit is configured as a primary crusher station for the expanded open pit, allowing truck-fed in-pit crushing with conveyor transfer to downstream processing. For mine planners and plant engineers, the successful commissioning confirms Chinese-built large semi-mobile gyratory technology as a viable option for high-throughput greenfield and brownfield expansions.

    LEEA GLAD procurement survey: compliance and lifecycle insights for mine teams

    LEEA has launched a procurement-focused survey to feed into a new white paper scheduled for release on Global Lifting Awareness Day (GLAD) on 2 July 2026, with details hosted on the updated campaign site globalliftingawarenessday.com. Targeted at stakeholders who specify or purchase cranes, hoists, slings and other lifting accessories, the initiative centres on the theme “Not all lifting equipment is…”, aiming to capture how compliance, whole‑life cost and inspection regimes are currently weighted in buying decisions. Mining owners, EPCMs and contractors can use the findings to benchmark procurement practices against industry expectations and tightening safety standards.

    Hitachi EH5000 100,000‑hour milestone at Lumwana: capex and fleet life notes for planners

    Three 296 t class Hitachi EH5000 rigid dump trucks at Barrick’s Lumwana copper mine in Zambia have each passed 100,000 operating hours, an unusually high lifecycle for ultra-class haulage equipment in hard-rock copper operations. The milestone, marked at a joint Barrick–Hitachi recognition ceremony, points to effective component rebuild strategies, condition-based maintenance and strong dealer support for the EH5000 fleet. For mine planners and maintenance teams, it signals potential to extend truck life beyond typical replacement cycles, with implications for capex timing and fleet renewal strategies.
