Product Features & Applications
Experience superior control with the LANDNEO SR12-B6. Featuring a fully hydrostatic all-wheel-drive system, a mechanical variable piston pump, and a constant piston motor for the drum, this 12-ton roller offers stepless speed adjustment and exceptional traction for maximum compaction efficiency.
Product Highlights
The LANDNEO SR12-B6 stands out due to its advanced hydrostatic power train, which eliminates the need for mechanical clutches or gearboxes, resulting in lower maintenance and smoother operation. The driving pump is a robust variable piston pump (75ml/r), providing precise flow control that translates into stepless speed variations. The drum drive utilizes a constant piston motor for reliable vibration output, while the rear axle drive motor ensures consistent all-wheel traction. This hydraulic synergy allows for effortless direction changes and precise positioning near curbs or obstacles, significantly improving job site efficiency and operator confidence.

Applications
This roller is particularly effective in projects requiring high precision, such as trench backfilling, slope compaction (with 48% gradeability), and working in confined urban spaces where its tight turning radius and responsive steering are invaluable. It is also a top choice for quarry haul road maintenance and pipeline project soil stabilization.


Packaging and Delivery
To ensure the hydraulic components are free from contaminants upon arrival, the LANDNEO SR12-B6 is delivered with all oil ports tightly sealed and covered. The machine is securely fastened within a 40ft container or via flat rack, depending on quantity. Standard export packing materials are used, and delivery is coordinated via reliable shipping partners with full tracking information provided.

After-sales Service
We provide a dedicated spare parts kit for the hydraulic system with every order. LANDNEO offers remote diagnostics support and quick replacement services for pumps and motors. Our service engineers are available for site visits to conduct hydraulic system health checks and preventive maintenance training, ensuring your investment operates at peak performance for years.
