中铁二十局工程机械厂研制的国内最先进的大吨位全液压、双驱动压路机。在经过200h 的工业试验后正式下线。该机采用轮胎和振动轮同时驱动,并可谓频调幅,从而产生的压力达65t,提高了可压实的铺层厚度和压实深度,可一机多用,工作效率比传统的机型提高了3～6倍。 China Railway 20 Bureau Engineering Machinery Factory developed the most advanced large-tonnage hydraulic, dual-drive roller. After 200h after the industrial test officially off the assembly line. The machine uses the tire and the vibration wheel at the same time driven and can be described as amplitude modulation, resulting in the pressure of 65t, increased compaction ply thickness and compaction depth, can be a multi-purpose machine, the working efficiency than the traditional models increased 3 to 6 times.
