Caterpillar 323 vs Volvo EC140E
The Caterpillar 323 is about 66% heavier than the Volvo EC140E (25,000 vs 15,075 kg), which usually means more stability and lifting capacity but higher transport weight.
The Caterpillar 323 has about 43% more engine power (129 kW (173 hp) vs 90 kW (121 hp)).
Beyond the numbers, compare local dealer support, parts availability and resale value for Caterpillar and Volvo Construction Equipment in your region: over the life of a machine they often matter more than small specification differences.
