XP260.XP300 pneumatic Rollker is of super-heavy self-propelled pneumatic rollr,which is mainly applied to construction worl for base,sub-dase,fill and asphalt surface.lt is the ideal compactiog equipment for constructing high-grade express way, airport,seaport,embankment and industry buildings. XP260.XP300 pneumatic Rollker is featured in its 3-gear mechanical drive,pneumatic-hydraulic braking,water suction and sprin-kling system with big power,compressed sprinkling structure for tyre surface and hydraulic steering mechanism,etc. XP260.XP300 pneumatic Rollker is characterized of high working efficiency and compaction performance.By increasing or decreasing ballast and changing the pneumatic pressure in tryes may adjust the rolling pressure of tyres,which realizes the dense compaction on the layer material without leaving any false compaction,so as to ensure the road surface hardness and shearing strength.
