China roller machine market after years of development, the brand pattern matures, users began consideration in machine purchase, the price competitive advantage is no longer the only criterion, the influence of the brand, product performance and user experience increasingly prominent role, good compacting effect, pressure effect, high rate of use of hydraulic high low cost and high reliability and a simple and convenient operation of the roller to favored customers.
As a high-end roller leader, Sany near the main SSR200AC-8/SSR220AC-8 two hydraulic single drive single wheel roller, the two models in addition to the continuation of 31 SSR series single drumroller tough atmosphere and yet prudent appearance, a comprehensive upgrade of power system, construction performance, comfort and control key equipped with parts etc..
"Old cannon" heart: strong core, excellent strength
31 SSR200AC-8/SSR220AC-8 hydraulic single drive single wheel roller with three diesel engine products - Weichai 147kW high-power engine, to achieve precise control of fuel injection quantity of the engine with the oil pressure stable, uniform atomization, engine vibration and low noise, allowing users to have a better driving experience; fully into the exhaust, fuel system, more reasonable. Greatly improves the power ratio, can realize the maximum efficiency of operation.
For the upgrading of the country's three emissions to improve fuel quality, 31 SSR200AC-8/SSR220AC-8 engine developed a special water removal filter cartridge, the technology instead of the fuel tank electric pump function and cumbersome artificial pump oil exhaust. It can not only solve the problem that the engine is difficult to start or start flameout after burning wax in the hot and cold areas.
With the accurate transmission of engine power, 31 SSR200AC-8/SSR220AC-8 hydraulic single drive single drumroller rare by the German cross force top vibration pump, the vibration of the large displacement pump, power conversion and stability. Large displacement vibration pump and vibration motor make the system low pressure and high reliability.
In addition, the use of power system heat conduction control technology, makes the machine at 46 degrees Celsius under continuous operation does not boil". Good climbing ability, easy to conquer 30% slope.
"Old gun" force: full hydraulic compaction, higher compaction operation efficiency
31 SSR200AC-8/SSR220AC-8 two full hydraulic single drive single steel roller, equipped with 11T vibration steel wheel, rigid wheel thickness of 40mm. With double amplitude vibration mode, vibration force significantly, vibration frequency is up to 35Hz, the exciting force of up to 390kN, press the same density of pavement, enhance the brand competition efficiency than 16.7%.
In the operation of roller construction, the two 20T/22T roller performance is not inferior to the same tonnage models, and even comparable to the 24T roller.
The mechanical roller reciprocating rolling in operation, initial impact indentation, reversing the waiting time in just 5 seconds; the machine operation is complicated, step on the clutch, gear, brake, slowly release the clutch and a series of tedious operation, greatly reduces the work efficiency.
While the 31 SSR200AC-8/SSR220AC-8 hydraulic single drive single wheel roller transmission line (simple pump motor - driving rear axle), soft, smooth, can absorb the impact, can effectively solve the problem of the initial conflict; single pole operation, stepless speed regulation, before and after the conversion without waiting time, at any time on the road to repair the local convex position; large displacement vibration motor equipped with rat bag type lubricating structure patent vibration bearing, starting time of just 3 seconds, which can effectively solve the problem of complicated operation, construction can improve the efficiency of more than 20%.
Preliminary estimates, according to the work of 1500 hours per year, fuel 16L/h, 6 yuan /L, an annual savings of 1500X16X6X20%=28800 yuan.
Another major problem of the mechanical roller is that the replacement of the friction plate is cumbersome and inconvenient to maintain, and the 31 hydraulic single drive single wheel roller has no friction film, and is easy to maintain for life.
"Old gun" stability: stability, heavy parts, to ensure the reliability of the whole machine
In order to ensure the reliability of the 31 SSR200AC-8/SSR220AC-8 hydraulic single drive single roller road roller, product R & D personnel are fully equipped with the whole unit with heavy fittings.
Two models with a new design fuel filter system with three filters, improve filtering accuracy, including two with oil-water separating function to improve the efficiency of the separation of water, increase the amount of ash melting, and further enhance the adaptability of oil.
Wide range of vision is achieved in the three stage vibration reduction cab with ergonomic design. And are equipped with high-grade interior, suspension seats, dashboard, multi-function intelligent operation, excellent damping performance, the cab noise is lower than 84dB (A), far below the industry level, all details allow users to have a comfortable experience.
In addition, the main pump rear panel, convenient maintenance; end sinking design, fully meet the requirements of 1m * 1m international security perspective, effectively reduce the accident probability, always focus on the humanization design of the supremacy of the user experience.
The 31 main push of the two hydraulic single drive single steel roller, super performance with attractive prices, so that all hydraulic products, Mechanical prices to do. Two highly cost-effective models of high-end, showing 31 strength road pressure old guns, strong expansion of more high-end market, capture more users heart strength.
