Main features：
    1.Electro-hydraulic control mechanical drive, three-speed gear shift. Hydraulic vibration, Start-oscillation by electronic control, Hydraulic steering and easy to operation
    2.Articulated frame, flexible steering, nice appearance and streamlined design. The back casing can be turned up in a big angle for easily maintenance
    3.This roller has super compaction performance. Double amplitude which applies to different stage compaction works. This system also has the function of delayed transition and stable transition of amplitude
    4.Adopt the electro-hydraulic control gearbox combined with two boxes. Lower maintenance cost, change gear flexibly with comfortable operation
    5.Adopt the gas cap oil two wheel service braking and air-control internal expanding drum parking brake, The braking effect becomes more stable and reliable with double braking system
    6.An air-conditioner can be optional

  Application： 
  This roller mainly used in highway, dam, railway, airport and other large infrastructure projects tec. This road roller is to compact non-cohesive or semi-cohesive materials such as base, sandy soil, gravel, macadam, rock filler etc.
