Energy Resources operates the Ukhaa Khudag mine in Mongolia, one of the region’s significant coking coal operations. The site runs a mixed fleet of large hydraulic excavators, shovels and dozers in continuous service, where undercarriage is never a minor purchase.
01
The challenge
Undercarriage is a high-value, high-impact wear category. Component quality, replacement timing and reliability in service feed directly into machine availability, maintenance planning and total cost of ownership.
Energy Resources needed a more cost-effective route to undercarriage supply without giving up the reliability its fleet depends on. In aftermarket mining supply that is a difficult brief: a low price without dependability brings operational risk. The supply had to offer both.
02
What Akaliko supplied
Since August 2025, Akaliko has supplied Energy Resources with undercarriage across several machine platforms at Ukhaa Khudag:
- Liebherr R9250: complete undercarriage
- Hitachi EX3600: complete undercarriage, two sets
- CAT D10T: track groups, three
- RH170B shovel: complete track roller assemblies

Wear monitoring on site
On a periodic basis, the Akaliko team visits the site to check how the supplied components perform and wear in service. The visits include:
- Inspection of the supplied undercarriage assemblies while they work
- Wear measurement, including link pitch and other indicators, to estimate remaining life and plan bushing turns
04
Why it matters
For Energy Resources, this makes the supply closer to a lifecycle relationship: wear data supports maintenance planning, shows replacements coming earlier and shows whether the parts perform as expected.
For Akaliko, it closes the loop between what was supplied and how it performs in one of the most demanding aftermarket environments. Energy Resources has made several purchases across these machines since August 2025.

Outcome
All supplied items had been installed and were in operation by September 2026.
