Guangna’s 500 Tonly–CiDi–CATL trucks: design and power notes for mine engineers

30 Second Briefing
Inner Mongolia Guangna Coal has signed a deal with Shaanxi Tonly Heavy Industry, CiDi, CATL and Jiangsu Hengwang Digital Technology to deploy 500 all‑electric, autonomous wide‑body mining trucks at its Wuhai operations. CiDi will provide the autonomous haulage system, CATL will supply high‑capacity traction batteries, and Hengwang will integrate fleet control into a smart mine platform. The project signals rapid scaling of battery‑electric AHS fleets in Chinese coal, with implications for pit design, power infrastructure and maintenance regimes.
Technical Brief
- Procurement contract for 500 units was formally signed on 9 February in Wuhai, Inner Mongolia.
- Fleet will use Shaanxi Tonly wide‑body mining trucks, indicating focus on short‑haul, high‑throughput pit layouts.
- CiDi’s role as AHS technology provider suggests integration of vehicle‑side perception, control and V2X modules.
- CATL supplying traction batteries centralises cell chemistry, BMS logic and charging interface standards across the 500‑truck fleet.
- Jiangsu Hengwang Digital Technology will embed haulage data into a unified smart‑mine control and dispatch platform.
- Multi‑party structure (OEM, AHS, battery, digital platform) implies tightly coordinated commissioning, testing and change‑management phases.
- Scale of 500 units in a single complex will strongly influence future Chinese coal mine haul road and power substation design baselines.
Our Take
Among the 65 coal‑linked pieces in our database, very few involve large‑scale deployment of fully electric, autonomous haulage, so Guangna’s 500‑truck move in Inner Mongolia signals that automation and decarbonisation are now being pushed even in traditionally low‑cost coal basins.
For Shaanxi Tonly Heavy Industry and CATL, a fleet order of this size in Wuhai effectively serves as a proving ground for high‑volume battery haulage in harsh continental climates, which could de‑risk similar offerings for iron ore and copper operations covered elsewhere in our Mining category.
The involvement of CiDi and Jiangsu Hengwang Digital Technology suggests that Guangna is locking in a vertically integrated digital–hardware stack, which typically makes it harder for rival OEMs or software vendors to displace the system once the autonomous coal fleet is commissioned at scale.
