Road Roller NK142
Road roller Nk142 product features:
1. Road roller nk142 has the national 3 emission standard diesel engine, with good power performance, large torque reserve, low fuel consumption, energy saving and environmental protection.
2. The hydraulic vibration system is an open system composed of gear pump and gear motor. The reversing buffer device is set in the pilot type electro-hydraulic directional valve, which can effectively reduce the hydraulic impact pressure and prolong the service life of components.
3. The diesel engine has a vibration pump interface, which simplifies the power transmission of vibration and improves the reliability of the machine. With rear wheel mechanical drive, the transmission torque of clutch, gearbox and drive axle is large, and the walking system is reliable.
4.50% of the front wheel weight distribution, resulting in greater static line pressure. The optimized structure and vibration parameters of the vibrating wheel make the compaction surface smoother and the compaction efficiency higher. Two kinds of amplitudes meet the requirements of different working conditions.
