Key costs to factor into your undercarriage calculations include:

  • Initial Component Costs: This covers the original investment in undercarriage components when you first acquired the machine. These costs depreciate over the lifespan of the components and should be included in your calculations.
  • Midlife Maintenance: This includes costs for maintenance like turning bushes and pins, replacing seals, regrousing shoes, and swapping tracked rollers and idlers.
  • Inspection Costs: Necessary CTS or custom track service inspections to manage your undercarriage effectively. These typically take around half an hour per large machine inspection, done every 500 hours, plus additional time for detailed reporting.
  • Component Replacements: Costs for labour and parts when components need replacing. It’s important to note these costs exclude any lost production if replacements are planned.
  • Frame Rebuilds: Costs for rebuilding frames, including parts, labour, and miscellaneous expenses. Rebuilt frames may be reused on another machine, while new or rebuilt frames on the current machine add to its total cost.

Period for this calculation – To determine cost per hour, accumulate all costs incurred from the start of the machine’s life and divide by its total operating hours.

Cost Controllable Factors

  • Emergency costs – proper planning of replacement inventory avoids the emergency delivery costs
  • Short Component Life – more hours achieved on the same components; component selection is critical here.
  • Maintenance – this involves planning undercarriage maintenance activities to achieve maximum life with the least number of interventions.

These considerations help ensure reliable undercarriage cost performance on all your tracked equipment – including dozer undercarriage, bulldozer tracks, track type tractors and crawler tracks.
