Caterpillar 313 vs Hitachi ZX135US-7
The Hitachi ZX135US-7 is about 12% heavier than the Caterpillar 313 (15,450 vs 13,800 kg), which usually means more stability and lifting capacity but higher transport weight.
The Caterpillar 313 has about 9% more engine power (81 kW (109 hp) vs 74 kW (99 hp)).
Beyond the numbers, compare local dealer support, parts availability and resale value for Caterpillar and Hitachi in your region: over the life of a machine they often matter more than small specification differences.
