1) Mechanical drive, three-speed gear shift. Hydraulic vibration, start-oscillation byi electric control, hydraulic steering and light operation.

2) Articulated frame, flexible steering, nice appearance and streamlined design. The back casing can be turned up in a big angel for easily maintenance.

3) This roller has supper 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 special gear-box with synchronizer, easy to operate and comfortable.

5) An air-conditioner can be optional.
