12ton hydraulic double drive single drum road roller CV123U/CV123PDU
CV123U single-steel roller compactor is a medium-sized, self-propelled, single-steel, full-hydraulic vibratory roller. It has the characteristics of large excitation force, high compaction efficiency, and good compaction quality. Compaction of foundation, sub-base and rock fills for highways, airports, ports, dams and industrial construction sites.
Equipped with Cummins electronic control engine, water-cooled, turbo-charged, large power reserve, low fuel consumption and low noise. Emissions meet Euro III standards.
The closed hydraulic system composed of imported variable pump constant-volume motors ensures that the roller has good driving performance and high climbing ability.
The imported medium-sized drive axle with anti-slip differential can automatically realize the torque distribution according to the road conditions, ensuring that the roller can exert its maximum traction under various working conditions.
The imported variable pump constant-volume motor is used to form a closed hydraulic system with dual frequency and double amplitude. The scientific and reasonable static line load and excitation force configuration ensure effective compaction of different types of materials and different thickness of the pavement.
The vibrating wheel adopts the inner cylinder type vibration chamber structure, which has a simple structure, high strength, and good rigidity. It has a dual-frequency and double-vibration function. It has a large static line pressure and a strong excitation force. It has a high operating efficiency. The vibration bearing uses a special vibration bearing for a long life , High reliability.
According to the principle of ergonomics, the instrument box integrates components such as the steering wheel, various meters, and key start switches, which are beautiful and practical, and improve the operating comfort.
The control box is located on the right side of the seat, which is convenient and labor-saving. Suspended, seat belt seat, safe and comfortable.
Anti-rollover cab (chamber), suspended seats, wide field of vision, providing a safe and comfortable operating environment for the driver.
The large-angled forward hood makes the maintenance area clear.
