Useful inputs include tramming height limits, drift width, grades, turning constraints, road conditions, required lift or deck loads, task frequency, typical travel distance, ventilation constraints, maintenance access limits, site safety requirements, and preferred service model. The strongest RFQs include drawings, photos, existing fleet pain points, and the tasks the mine is trying to consolidate or improve. Without that information, the discussion usually becomes a spec-sheet comparison rather than a mine-fit evaluation.
