山东常林集团自主开发生产的具有国际先进水平的新一代RD120型双钢轮压路机。其主要的性能特点为:全液压双轮驱动、双轮振动;前后车架均采用无框架结构,能够最大限度接近障碍物并进行压实作业,工作宽度可以达到2 530 mm, 独特的双铰接蟹行机构,能够保证碾压过程中前后钢轮错开达到200 mm;无级调频、可调节振幅的振动系统,能够适应超薄至超厚任意铺层的有效压实;整机采用全电液控制,无换挡操纵杆、脚制动、手制动等机械操纵机构,使得驾驶更为舒适简便。该机具有独特的制动系统,使行车安全得到了充分的保证,当工作或一般行车时,使用静液压制动可以实现柔性停车
Shandong Chang Lin Group independently developed and produced with the international advanced level of a new generation RD120 double drum roller. Its main features are: full hydraulic dual-wheel drive, two-wheel vibration; front and rear frame are used frameless structure, to maximize access to obstructions and compaction operations, working width up to 2 530 mm, the unique double hinged Crab line agencies, to ensure that the rolling process before and after the roller staggered up to 200 mm; stepless frequency modulation, adjustable amplitude vibration system can be adapted to ultra-thin to super-thick any ply effective compaction; machine using all-electric Control, no shift lever, foot brake, hand brake and other mechanical control mechanism, making driving more comfortable and convenient. The machine has a unique braking system, so that traffic safety has been fully guaranteed, when working or general driving, the use of hydrostatic braking can achieve flexible parking
