VOLVO DD77DA STATIC SMOOTH DRUM ROLLER

Technical Description

The Volvo DD77DA Static Smooth Drum Roller is a robust compaction machine designed for efficient soil and asphalt compaction. It features a 66-inch wide smooth drum that delivers uniform compaction with a vibration frequency of 42 vibrations per minute (vpm), enabling effective ground smoothing and densification. The roller’s operating width is 73 inches, and it offers an inside turning radius of 122 inches, providing good maneuverability for various site conditions. Powered by a Kubota V3800DI diesel engine, this machine benefits from a reliable, turbocharged 4-cylinder engine known for its durability, fuel efficiency, and compliance with emission standards. The Kubota engine typically delivers around 75 kW (approximately 100 HP) at 2600 RPM, ensuring ample power for continuous operation under demanding conditions. This vertical, water-cooled engine enhances operational reliability and reduces downtime with easy maintenance features. The DD77DA is part of Volvo’s lineup of smooth drum rollers, designed to provide superior soil compaction performance through static weight combined with vibration, ideal for road construction, site preparation, and other civil engineering projects where uniform compaction is critical. Its dimensions and engine specifications make it suitable for projects needing a balance between power, operational width, and maneuverability. Overall, the Volvo DD77DA combines proven compaction technology with a durable powertrain to deliver reliable and consistent compaction results in a wide range of construction environments.
