YZ7G Single Drum Vibratory Rollers (7ton) YZ7G单钢轮振动压路机 YZ7G型振动压路机为自行式铰接转向振动压路机，适用于公路建设、停车场、及工业性场院及其它受限制区域的压实，更以其具有的宽震动轮(1.7m)和适宜的压实速度（15km/h）所形成的巨大生产能力非常适宜于大型沥青碾压和道路的修铺工作，是道班配置的理想设备。
YZ7G vibratory roller make use of the latest technique inside or outside the ration, is based on the my ration to make the latest level roller. The machine is weight of seven ton, the front wheel is vibrated and the behind wheel is smooth-wheel which drive the whole roller, and the roller is articulated steering and auto-watering on the front and back wheel. The roller is equipment used for asphalt road surface, basic layer, hypo-layer and road filled.The roller is mostly worked in with the spreaded asphalt machine. Because of the very width vibrated wheel<1.7m> and the fine pressing speed which bring the great working ability. It is mostly worked with the largest spreaded asphalt. At the same time, the taller greatly repairs the road-surface because it has the highest turn table speed<15km/h>.The roller is applied to build-road, parking area and industry area, it is especially suited for express shoulder, side walk and the limited area.The roller optimal function and controlling and maintaining capability are the optimal choice.Mechanical travel drive, hydraulic vibration and articulated steering and the whole roller with optimal function/worth ratio and reliable performance. Hand brake and foot pedal brake, assure the machine's safety and dependability. Adopt the high grade engine of 495 shift gears behind the roller. completely opening cover offer the optimal the space of maintaining. Auto-watering on the front and back wheel spacious and comfortable cab.工作质量(Operating mass)7000kg激振力(Inspire force)70kN振动频率（Vibration frequency）50Hz振幅(Vibration amplitude)0.4mm行走速度(Travel speed)2.2km/h
