Masalta Diesel Double Drum Road Roller, 10 HP - MDR65Y

Double Drum Road Roller 650mm

Executing precise pavement consolidation requires machinery that eliminates mechanical power losses. The Masalta MDR65Y abandons traditional chain and belt drives in favor of a sophisticated, fully hydraulic architecture for both locomotion and vibration. This heavy-duty walk-behind compactor relies on a premium Yanmar L100 diesel engine. This air-cooled, 4-stroke power plant delivers a steady mechanical output, propelling the 760 kg unit while driving high-torque hydraulic pumps. The integrated electromechanical system generates a substantial 21 kN of centrifugal force at a precise 55 Hz (3,300 vpm) frequency. This downward energy transfers directly through the dual 650 mm wide by 404 mm diameter steel drums, ensuring structural base materials and asphalt layers are compressed safely to their maximum density specifications.

The physical geometry and fluid management systems of the MDR65Y are strictly optimized for demanding civil engineering tasks. Operators maintain total control over the infinitely variable walking speed, which ranges smoothly from 0 to 3.6 km/h, allowing for meticulous and uninterrupted passes over fresh asphalt. The machine is engineered with minimal side-clearance overhang, permitting technicians to maneuver closely against walls, tight curbs, and pavement boundaries. To maintain continuous operation, the compactor is outfitted with a built-in hydraulic oil cooler to preserve system pressure during long shifts, alongside a generous 65-liter corrosion-free water tank that lubricates the drums to prevent material adhesion. Safety and ergonomics are deeply integrated via an isolated anti-vibration handle assembly that reduces operator fatigue, and a critical dead-man reversing lever that instantly protects the user in case of accidental trips or loss of control on inclines of up to 30% gradeability.

Key Features & Benefits:

• Fully Hydraulic-Drive Architecture: Features a premium hydraulic pump and dual motor configuration that directly drives both mechanical travel and high-speed vibration, entirely eliminating maintenance-heavy chain and belt systems.

• High-Output Diesel Power: Driven by a premium, single-cylinder Yanmar L100 diesel engine equipped with an electric starter to ensure high-torque performance and sustained mechanical stability under intense compaction loads.

• High Vibration Frequency: Operates at a rapid 55 Hz (3,300 vpm) frequency, precisely controlled by a simple on/off switch to allow operators to manage compaction depth and prevent the over-compaction of sensitive substrates.

• High-Impact Compaction Force: Generates a substantial 21 kN (2,141 kgf) of mechanical compaction force, engineered to settle thick sub-base materials and granular soils efficiently into a rigid, load-bearing foundation.

• Precision Speed Control: Provides a completely adjustable and seamless walking speed ranging from 0 to 3.6 km/h via an easy-to-reach, step-less control lever for optimal pacing on fresh asphalt.

• Dual-Drum Tracking: Outfitted with two heavy-duty steel drums, each measuring a wide 650 mm in width and 404 mm in diameter, ensuring excellent weight distribution and maximum surface coverage per pass.

• High Gradeability Performance: Features high-torque hydraulic motors capable of conquering steep site inclines and transport ramps, providing a certified maximum slope-climbing capacity of up to 30%.

• Effortless Starting Mechanism: Equipped with a dependable electric starting system that ensures effortless engine ignition, minimizing physical exertion and facilitating quick deployment even in cold weather conditions.

• High-Capacity Water Sprinkling: Integrates a large 65-liter corrosion-free water tank mounted at the rear to constantly lubricate the drums, effectively suppressing dust and preventing asphalt stickiness during hot rolling.

• Dual Scraper Bars: Built with two heavy-duty scrapers on each drum to continuously clear away sticky materials, mud, and debris while rolling, maintaining a completely smooth drum surface.

• Dual Beveled Smooth Drums: Designed with exceptionally smooth outer steel drum surfaces and specialized beveled edges to systematically prevent leaving unsightly grooves or indentation marks on freshly laid asphalt layers.

• Dead-Man Reversing Protection: Incorporates a vital safety lever into the main operator handle, instantly triggering a reversing mechanism if the operator trips or loses physical control, providing crucial accident protection.

• Tight Obstacle Clearance: Engineered with a highly compact frame featuring minimal side and curb overhang, enabling operators to roll tightly and accurately against structural walls, pavements, and concrete barriers.

• Anti-Vibration Handle Assembly: Outfitted with an isolated, multi-position steering handle that significantly lowers Hand-Arm Vibration (HAV) for the operator, and folds down neatly to facilitate compact transport inside standard commercial vehicles.

• Built-In Hydraulic Oil Cooler: Includes an efficient, integrated thermal cooling block that actively dissipates accumulated heat during continuous high-vibration runtime, preserving hydraulic oil viscosity and maintaining peak system pressure.
