Single drum vibratory rollers are self-propelled compaction machines that combine static weight + high-frequency vibration to compact soil, aggregate and base materials efficiently — improving foundation bearing capacity and long-term stability. Essential equipment for road building and large-scale infrastructure.

• Vibration System: Premium vibration bearings and precision eccentric mechanism; dual-amplitude (High/Low) adapts to varying compaction depths; full compaction width, uniform density, no surface loosening

• Power Unit: Stage III / Stage IV compliant diesel engine; ample power reserve, low fuel consumption, reduced emissions — meets regional environmental requirements

• Travel & Control: Full-hydraulic 2-wheel drive / 1-wheel drive options; stepless speed; smooth travel, excellent gradeability; articulated steering delivers tight turning radius for confined-site maneuverability

• Structure & Service: Abrasion-resistant thickened manganese steel drum; robust chassis; wide-open engine hood and grouped service points simplify daily checks; optional air-conditioned cab, suspended seat, rear-view camera for all-day operator comfort.
