Tonly wide body trucks at Kaltim Prima: performance and cost lens for mine planners

First reported on International Mining – News
30 Second Briefing
Tonly has deployed a fleet of its Chinese-built wide body mining trucks at Kaltim Prima Coal’s flagship open-pit operation in Sangatta, East Kalimantan, working under mining contractor Darma Henwa. The deal marks the first entry of a Chinese wide body truck brand into Indonesia’s premier coal mine, signalling growing acceptance of non-traditional OEMs in high-production haulage fleets. For mine planners and maintenance teams, the move raises practical questions on lifecycle cost, parts support and performance of wide body trucks under KPC’s high-rainfall, high-utilisation conditions.
Technical Brief
- Fleet comprises Tonly wide body mining trucks operating in overburden and coal haulage at Sangatta.
- Deployment gives Tonly direct exposure to Indonesia’s high-volume export thermal coal supply chain.
- Operating environment includes tropical rainfall, soft ground conditions and long haul profiles typical of East Kalimantan.
- For other Indonesian coal operations, contractor-led trials offer a low-risk pathway to test alternative haulage OEMs.
Our Take
Our database shows multiple recent Tonly case studies pairing wide‑body trucks with autonomy or battery‑electric platforms; if similar technology pathways are followed at Kaltim Prima Coal, Darma Henwa could later leverage this fleet for staged automation or partial electrification without changing truck form factor.
Coal is one of the more frequently covered commodities in our mining project pieces, and the addition of Kaltim Prima in Indonesia alongside Zhundong and Inner Mongolia Guangna Coal in China underlines that wide‑body haulage is becoming a standard option for large open‑pit coal operations rather than a niche Chinese solution.
