Technical Features

RS8220 is a mechanical single-drum vibratory road roller in the heavy-duty self-propelled vibratory series, able to compact various soil layers and do rocks filling in high efficiency. Such machine leads the industry in compacting performance, driving performance, manoeuvrability, reliability and serviceability etc., being the ideal choice for compaction of high-grade highways, airport, port, railway, embankment and industrial site.

Reliability
1,It is applied with the Weichai engine meeting the China II emission standard, which features strong power, energy saving and good reliability, and configures itself with the starting enrichment function.
2,It is applied with the electro-hydraulic power shift transmission, which has three forward gears and three reverse gears and features neutral start and reverse warning function, allowing stable, handy and comfortable gearshift.
3,The strengthened drive axle specific to the road roller enjoys reliable performance .
4,It is applied with the internationally well-known vibratory pump and vibratory motor, ensuring reliable performance.
5,It applies the excitation mechanism of the rsquo;s patented technology for invention, so it has good consistency in vibration amplitude and frequency on both sides of the vibration wheel and good compaction effect.
6,The sealing spacer is designed for the cooling compartment to separate the cool room from the hot room, thus enhancing the cooling efficiency.

Convenient
1,It uses the digital stepping instrument display andhigh man-machine interaction, and the electrical systemof the whole machine is under the centralized control, which facilitates detection and maintenance
2,The electrically-controlled linear actuator provided for the engine hood allows for one-button open of hood to a large angle, and the maintenance parts are rationally arranged to facilitate the maintenance and service.

Comfort
The new full-enclosed cab is optimized ergonomically, which is spacious and bright with broad field of view and good sealing performance; the A/C and ROPS&FOPS are optionally available to enhance the operating safety and comfort.

2. Feature:

Shangchai SC8D series turbocharged diesel engine is jointly developed with Austrian AVL, featuring prominent performances, high reliability, and good fuel economy, and is one mainstream installed engine in China's construction machinery industry.Shantui's patented new vibratory drum features more excellent structure and stability performances. The super-high lubricating oil capacity guarantees the good lubrication and cooling for the vibra The vibratory pumps and vibratory motors adopt international renowned brand products to guarantee the reliability and compacting performance of the vibration system.The single gearshift joystick can effectively promote the working efficiency of the operator and relieve the fatigue. The imported comfortable and firm seat adjustable in longitudinal direction is equipped with the left and right foldable armrests and the retractable seat belt. The cab is equipped with air conditioning system to provide a comfortable working environment and the rubber damper design isolates the operator from the vibration source to remarkably relieve the working strength.Two independent brake systems, namely service brake (foot brake) and parking brake (handbrake), feature stable braking, high safety and reliability, simple structure, and easy maintenances. Standard double-amplitude function expands the application scope of the equipment. The high span between high and low centrifugal forces helps the establishment of compacting schemes for different density specifications. The design of the drum vibration parameters conforms to the requirements of working site and multiple optional equipment are provided to enhance the working condition adaptability of the machine. Large angle openable hood, maintenance-free battery, real-time monitoring of pressures and temperatures, and reasonable arrangement of diesel and working oil tanks enable Shantui road roller to realize excellent maintenance performance, shorten the shutdown time, and improve the utilization rate of whole machine.
