Masalta Diesel Double Drum Road Roller, 8.4 HP - MDRS65K

Vibrator Roller Compactor 650mm

Compacting asphalt and granular soils in confined spaces requires highly maneuverable equipment with exceptionally sensitive controls. The Masalta MDRS65K walk-behind road roller addresses these exact spatial constraints by utilizing a fully hydraulic drive architecture, equipping the machine with high-quality hydraulic pumps and motors to manage travel. Powered by air-cooled 4-stroke Kubota E75-NB3 diesel engine, this 630 kg compactor guarantees smooth, responsive locomotion. The internal electromechanical module operates at a steady 55 Hz (3,300 vpm), generating an 11.3 kN (1,152 kgf) compaction force that is mathematically paired with a static linear force of 51 N/cm. This dual-action pressure transfers evenly across the dual 650 mm wide by 402 mm diameter steel drums, effectively consolidating base materials and fresh asphalt layers without over-compacting sensitive substrates.

Operational efficiency on tight paving sites is maximized through the machine's highly compact structural layout. The MDRS65K features minimal side and curb clearance, empowering contractors to roll seamlessly against concrete walls, tight curbsides, and structural boundaries. An ergonomically designed handle lever allows operators to adjust the walking speed fluidly between 0 and 3.6 km/h, ensuring consistent overlapping passes on the pavement. To prevent material accumulation on the drums, the unit integrates custom dual scraper bars and a built-in 40-liter corrosion-free water tank for continuous surface sprinkling. Safety protocols are rigorously implemented throughout the design; it includes a vital dead-man reversing lever on the steering handle to prevent crushing accidents, and a dedicated mechanical parking brake ensuring the machine remains fully immobilized on transport ramps and steep site inclines with up to 30% gradeability.

Key Features & Benefits:

• Fully Hydraulic-Drive Architecture: Features premium hydraulic pumps and heavy-duty motors that deliver highly sensitive control, directly driving smooth and responsive machine travel without mechanical lag.

• High-Output Kubota Engine: Driven by a premium, single-cylinder 8.4 hp (6.3 kW) Kubota E75-NB3 diesel engine, specifically selected to ensure consistent, high-torque performance under intense daily compaction loads.

• Optimized Compaction Force: Generates a reliable 11.3 kN (1,152 kgf) of dynamic compaction force paired seamlessly with a static linear force of 51 N/cm to achieve steady, dense structural consolidation.

• Consistent Vibration Frequency: Operates continuously at a rapid 55 Hz (3,300 vpm) frequency, designed to efficiently settle granular base materials and remove air voids from fresh asphalt mixtures.

• Precision Speed Adjustment: Provides a completely adjustable walking speed ranging from 0 to 3.6 km/h via an easy-to-reach, ergonomically designed handle lever, allowing operators to match the exact pace required for the surface.

• Dual-Drum Configuration: Outfitted with two robust steel drums, each measuring 650 mm in width and 402 mm in diameter, guaranteeing excellent weight distribution and consistent tracking across the paving line.

• Corrosion-Free Water Sprinkling: Utilizes an integrated 40-liter corrosion-free water tank to keep the steel drums continuously lubricated, effectively minimizing asphalt stickiness and actively suppressing site dust.

• Dual Beveled Smooth Drums: Constructed with exceptionally smooth outer steel surfaces and specialized beveled edge designs to prevent leaving unsightly grooves or mechanical indentation marks on freshly rolled asphalt.

• Continuous Scraper Bars: Built with two durable scraper bars on each drum to continuously clear away sticky materials, asphalt buildup, and mud, maintaining a pristine rolling surface.

• Effortless Starting Mechanism: Equipped with a highly dependable electric starting system that ensures effortless, turnkey engine ignition, promoting rapid deployment even in harsh or cold weather conditions.

• Dead-Man Reversing Protection: Integrates a crucial safety dead-man lever directly into the operator handle, offering instant reversing protection to halt the machine if the operator trips or loses physical control.

• Mechanical Parking Brake: Includes an integrated, manual mechanical parking brake system designed to safely secure and completely immobilize the roller on steep slopes or during transit on flatbed vehicles.

• Tight Obstacle Clearance: Engineered with a compact chassis offering minimal side and curb clearance, enabling operators to achieve the closest possible approach to roll tightly against retaining walls and pavements.

• High Gradeability Performance: Built with excellent hydraulic traction capabilities, allowing the heavy machinery to confidently conquer steep inclines and job site ramps with a certified maximum slope capacity of 30%.
