road roller ,COMMINS 4BTA3.9 water cooled diesel engine,hydraulic motors at two range infinitely variable speeds,,RCC

Hydraulic double drum vibratory road rollers are manufactured according to international advanced technology and by use of imported main components abroad, suitable for compaction of various stabilized soils, bituminous concrete and rolling cement concrete (RCC) on road surface construction, also for compaction of road base course, which are universal compaction equipments for high-class highway, airport, harbors, dams, municipal road and industrial ground. Imported COMMINS 4BTA3.9 water cooled diesel engine with rich power surplus Hydrostatic all-drum travel drive by imported hydraulic motors at two range infinitely variable speeds.Dual frequency and amplitudes vibration system with imported piston pump and motors.Center articulated steering with crabwalk unit for flexible maneuverability.Integrated multi-disc wet brake with oil-cutoff braking for reliable safety.Modernized style appearance design with inner bending side plate supports posses beautiful shape contour.Upper surface of the drum exposed-fully, front and rear visibility may reach 1×1 meter standard for convenient observation of driver.Driver's platform can be turned for 180 degree; All controls are ergonomically designed for light and ease operations.Two sets of imported water pumps, large capacity water tanks and sprinkler pipes raise operational reliability.
