Master Control System (MCS) vibratory control: correlation control of eccentric shaft revolve & traveling direction (8-amplitude system): eccentric shaft revolve can change with the travelling direction, always ensure the material to be drawn beneath the iron drum, rather than lifting up the material with the drum revolve, this will improve the evenness of road. Automatic vibratory control: avoid the slakeless spoor on the hot paving asphalt when in parking and vibratory-starting. Vibratory can adjust according to real condition.  The correlation of travelling speed and vibrating frequency: through coordinating the vibrating and travelling speed, to obtain better compacting and evenness.  MaintenanceVertically-opened engine hood enables the serviceman to approach the engine, pump and motor etc. and to refuel easily.  Braking systemAdopt hydraulic-driven automatic-locking braking mode, the friction plate of travelling motor will lose only when the engine is delivering the power and vehicle is in travelling operation. This ensures a reliable stop and the safety for hang-up in the slope work.Security SystemMedium-starting protection and braking protection have the regulation on the rotating speed of engine.Operating systemfront-driver’s seat can be revolved in 180° and provides a max. view which enable the side rolling easier and more accurate. Sprinkler SystemEquipped two water tanks (F/R each) adopt independent sprinkler system separately and 3-step water filtering system. Automatic sprinkling function can control the flow rate and produce the atomized water.
