YZJ－2型机械驱动铰接式液压振动压路机是我厂利用专利（实用新型专利号：300255）技术生产的中型压路机（图1）。它具有较大的激振力和静线压力，适宜于一般与特殊粘性与非粘性材料的压实，可用于基础碾压和路面处理（后轮换平轮）。转弯半径小，擦边性能良好，密实度达90％以 YZJ-2 mechanical drive articulated hydraulic vibratory roller is a medium-sized roller (Figure 1) produced by our factory using the patent (utility model patent number: 300255). It has a large excitation force and static pressure, suitable for general and special viscous and non-viscous material compaction, can be used for basic roller compaction and road surface treatment (rear wheel flat wheel). Turning radius is small, good edge performance, the density of 90%
