Product Description
Master large-scale paving and earthwork projects with the Professional Ride-on Vibratory Road Roller. Engineered for elite industrial performance, this 1200kg tandem roller represents the pinnacle of compaction technology for professional contractors. Whether you choose the BRD850H (Gasoline powered by Honda GX390 or Briggs & Stratton) , you are investing in a machine built for maximum uptime and superior compaction density.
This heavy-duty double drum compactor features a state-of-the-art hydraulic system with a variable plunger pump and parallel motors, providing seamless stepless speed control and consistent power delivery. With a massive 22KN exciting force and a 930mm working width, the BRD850H delivers deep-reaching vibration that eliminates air pockets in sub-base materials and creates mirror-smooth asphalt finishes. Its articulated steering system allows for a tight turning radius, making it exceptionally maneuverable in confined municipal sites, parking lots, and highway repair zones.

-
Municipal Road Construction: Ideal for asphalt paving, road widening, and street maintenance.
-
Commercial Paving: Perfect for stabilizing sub-bases and finishing parking lots, office plazas, and gas stations.
-
Infrastructure Repair: High-efficiency tool for highway shoulder repairs, bridge deck finishing, and pothole patching.
-
Industrial Site Development: Used for compacting granular soil and gravel before pouring concrete for warehouses and factories.
-
Civic Engineering: Suitable for public squares, sports tracks, airport aprons, and large-scale residential driveways.
Key Features
-
Full Hydraulic Driving System: Equipped with a high-end variable plunger pump and double-wheel parallel motors for smooth, stepless speed changes and superior traction.
-
Massive 22KN Compaction Force: Delivers intense high-frequency vibration (65Hz) to ensure maximum density in fewer passes, saving time and fuel.
-
Precision Articulated Steering: Features a 28° swing angle with hydraulic cylinder control, providing exceptional maneuverability in tight urban spaces.
-
Premium Engine Options: Choose between world-class Honda GX390 gasoline power for reliable onsite performance.
-
Intermittent Pressure Sprinkling: Large 65L water tank with an optimized spray system prevents asphalt from sticking to the 12mm thick steel drums.
-
