2016 Shanghai BMW show, DOAN new generation of roller machine products on behalf of -DA-S88 single-wheel vibratory roller gorgeous debut. A new generation of DA-S88 single-wheel vibratory roller configuration DOAN independent research and development of electronic control direct shift power box, the use of electronic control direct shift technology can achieve no main clutch transmission, breaking the mechanical drive roller traditional transmission. Simple and comfortable operation, the atmosphere of the new appearance, simple and smooth lines, high-end reliable configuration, is bound to make DA-S88 single-wheel vibratory roller into a new generation of darling.
Large exciting force, ultra-thick layer compaction
DA-S88 single-wheel vibratory roller configuration DOAN vertical vibration wheel, with large exciting force, the maximum exciting force can reach 405kN, more suitable for filling, highway, railway, airport, water and other projects. Vertical vibration wheel in the horizontal direction, the vibration displacement is zero, which will help improve the quality of the surface of the pavement; vertical vibration wheel vibration energy is only vertical down, energy loss is small, the impact of large depth, to meet the ultra-thick laminating real.
With no technology leader
The DA-S88 single-wheel vibratory roller is equipped with a long-life vibrating wheel. The vibrating wheel adopts the light bulb design technology and oil spoon lubrication technology to further improve the reliability of the vibration wheel, enhance the vibration bearing, vibration structure and The life of the exciter, and passed a 3000 hour bench test. At the same time, DA-S88 single-wheel vibratory roller with ultra-high efficiency: through the theory and a large number of experimental research, optimize the quality of the assembly and unloading ratio, to achieve maximum vibration energy transfer to ensure consistency of consistency, increased compaction Efficiency; vibration wheel center of the vibration quality center, the center of the excitation force and geometric center coincidence, to ensure that the vibration wheel axis is exactly what the amplitude of any point is exactly the same, so as to improve the dynamic compaction efficiency of the road; vertical vibration roller After the real operation of the surface without cracks, high flatness, in the actual construction process, no need for secondary static pressure reinforcement surface.
DA-S88 single-wheel vibratory roller configuration efficient cooling fan, engine engine interior with diversion duct technology and flexible sealing technology, with high heat efficiency. In addition, DA-S88 single-wheel vibratory roller configuration DOAN electric control direct shift power box, power box through the elastic coupling directly connected with the engine flywheel shell, cancel the main clutch and other intermediate transmission, transmission efficiency is extremely high. DOAN electric control direct shift power box according to the operation and non-operating state set three gear speed, give full play to the power box transmission efficiency, transmission efficiency is extremely high.
Energy saving and environmental protection operation comfortable
DA-S88 single-wheel vibratory roller configuration on the firewood SC8D low-speed electronic control high pressure common rail water-cooled diesel engine, powerful, to meet the country Ⅲ emission standards, supplemented by the median automatic idling function, with fuel-efficient, low noise. Configuration DOAN electronic control direct shift power box, cancel the main clutch and other intermediate transmission device to enhance the efficiency of the drive system, energy efficient. Using rack anti-vibration technology, reduce the vibration and unevenness of the rack vibration, saving vibration energy consumption. DA-S88 single-wheel vibratory roller to cancel the foot clutch, the liberation of the left foot, can be directly switched, simple and convenient. Control joystick integrated walking, vibration, throttle control and other functions, to achieve a single handle manipulation, super good operation.
DA-S88 single-wheel vibratory roller with a large exciting force, long life, high efficiency, super energy and super good operation characteristics, and will subvert the traditional, continued writing DOAN roller brilliant legend.
