Caterpillar D8 vs Komatsu D155AX-8
The Komatsu D155AX-8 is about 3% heavier than the Caterpillar D8 (40,000 vs 39,000 kg), which usually means more stability and lifting capacity but higher transport weight.
Beyond the numbers, compare local dealer support, parts availability and resale value for Caterpillar and Komatsu in your region: over the life of a machine they often matter more than small specification differences.
