Caterpillar 320 vs SANY SY500H
The SANY SY500H is about 126% heavier than the Caterpillar 320 (49,000 vs 21,650 kg), which usually means more stability and lifting capacity but higher transport weight.
The SANY SY500H has about 117% more engine power (280 kW (375 hp) vs 129 kW (173 hp)).
Beyond the numbers, compare local dealer support, parts availability and resale value for Caterpillar and SANY in your region: over the life of a machine they often matter more than small specification differences.
