12Ton Double drive single steel wheel roller

The KS121D is a 12-ton single-drum vibratory roller engineered as a high-performance and versatile solution for demanding compaction tasks. Its core strength is a powerful and intelligent dual-amplitude vibration system (200/100 kN), allowing it to efficiently compact everything from deep soil layers to asphalt surfaces. The machine's formidable weight (12,000 kg) and high static linear load (333 N/cm) deliver exceptional compaction force, while its excellent 42% gradeability and 410 mm ground clearance ensure capability on challenging terrains. Despite its power, it remains highly maneuverable with a tight turning radius. Driven by a reliable Weichai engine and supported by a robust hydraulic system from trusted suppliers like Fenyi and Hytek, the KS121D offers contractors a productive, durable, and cost-effective machine for achieving high-quality, specification-compliant compaction results across a wide range of road construction and earthworks projects.

Excellent Gradeability and Rough-Terrain Performance

Featuring an impressive 42% gradeability, the KS121D excels on steep slopes and challenging job sites often encountered in large earthwork projects. Coupled with a generous 410 mm minimum ground clearance, it navigates rough, uneven terrain with ease, maintaining productivity in demanding conditions.

Highly Maneuverable and Efficient Operation

Despite its powerful build, the roller maintains excellent site agility with a compact length of 5,940 mm and a tight turning radius of 6,250 mm. This combination allows for efficient operation and easy maneuvering in confined spaces, reducing cycle times and enhancing overall project workflow.

Reliable and Fuel-Efficient Weichai Powertrain

Powered by a dependable 97.5 kW Weichai engine that meets China Stage II emission standards. This powertrain delivers robust and consistent performance for all-day operation while ensuring good fuel efficiency, contributing to lower operating costs and reliable uptime.

Proven Hydraulic Drive System for Smooth Control

Incorporates high-quality, market-proven hydraulic components including a Fenyi drive axle, Hytek drive motor and pump, and Tianji vibration motor and pump. This integrated system ensures smooth travel, precise vibration control, reliable power transmission, and ease of maintenance.

Optimized Drum Design for Maximum Efficiency

The large 1,500 mm diameter and wide 2,100 mm width of the vibration drum provide an optimal balance between impact energy and coverage area. This design maximizes productivity by delivering effective compaction force while reducing the number of passes required to achieve specification density.
