KS121S features excellent compaction performance, great compaction depth and high operating efficiency. Suitable for compacting various non-cohesive materials such as soil, gravel, crushed stone, sand and gravel mixtures, rock fills and various stabilized soils for subgrade and pavement projects. Widely used in highways, municipal works, airports, ports, wharves, dams and various industrial construction sites.
Equipped with Weichai WP4G engine, delivering 97.5 kW ratedpower. Features instant start, convenient electric shutdown,strong and durable performance, plus lower fuel consumption.
Adopts a hydraulic heavy-duty drive axle, which automatically distributes torque according to road conditions, ensuring the road roller delivers maximum traction required under all working conditions.
An open hydraulic vibration system consisting of a fixed-displacement gear pump and a motor is used, with a scientifically and rationally configured static linear load and excitation force to ensure efficient compaction of different types of material layers.
The cab features excellent sealing performance and can be optionally equipped with air conditioning and luxury seats.
It offers a spacious interior with large-area glass windows for wide visibility, providing operators with a safe and comfortable working environment.
The vibratory drum adopts a two-point support and reinforced inner cylinder vibration chamber structure, featuring simple structure, high strength and good rigidity.
