Caterpillar CS56B vs Hamm HD+ 120i

The Hamm HD+ 120i is about 9% heavier than the Caterpillar CS56B (12,000 vs 11,000 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 Wirtgen Group in your region: over the life of a machine they often matter more than small specification differences.
