Caterpillar 313 vs Komatsu PC138USLC-11
The Komatsu PC138USLC-11 is about 19% heavier than the Caterpillar 313 (16,357 vs 13,800 kg), which usually means more stability and lifting capacity but higher transport weight.
The Caterpillar 313 has about 11% more engine power (81 kW (109 hp) vs 73 kW (98 hp)).
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.
