Hitachi ZC50C Combined Roller – 4 t Compact Vibratory Roller

The Hitachi ZC50C is a 4-ton class combined vibratory roller (steel front drum + rear rubber tyres) designed for finish compaction of asphalt and base materials on roads, car parks and urban worksites. Its compact body, excellent visibility and short turning radius make it easy to operate in tight spaces while still delivering uniform, high-quality compaction.

Powered by a fuel-efficient Kubota three-cylinder diesel engine and equipped with a 1.3 m wide front drum, the ZC50C offers strong vibratory performance and stable travel, making it suitable for both small civil projects and road maintenance work.
