LTU120Ⅲ型高等级沥青摊铺机是三一重工股份有限公司在LTU120Ⅱ型沥青摊铺机的基础上自主开发研制的新一代高科技产品,摊铺宽度2.5～12m,行走系统采用三一沥青摊铺机成熟的结构形式,重新布置四轮一带,调整支重轮的布置间距,使整机重量更合理均匀地分布到台车架上,彻底解决了支重轮易出现早期磨损特别是靠近驱动轮的最后一个支重轮异常损坏及其余支重轮磨损不均的问题。该机拥有很多创新技术并有多项已获国家专利,如受料斗与履带板之可调节缓冲装置,发动机、液压系统散热装置,熨平板自动张紧装置,全球定位系统和路沿跟踪器等。
LTU120 Ⅲ type high grade asphalt paving machine is a new generation high-tech product independently developed by Sany Heavy Industry Co., Ltd. on the basis of LTU120 Ⅱ asphalt paver. The paving width is 2.5 ~ 12m and the walking system is paved with Sany asphalt Machine structure of the mature, rearrange the four rounds of the area, adjust the layout of the roller wheel spacing, so that the whole weight more reasonable and evenly distributed to the car frame, completely solve the early wear and tear of the roller is prone to especially near the drive wheel The last one abnormal damage to the roller wheel and the remaining roller wheel wear uneven problem. The machine has many innovative technologies and a number of national patents have been granted, such as by the hopper and the track adjustable cushioning device, the engine, the hydraulic system cooling device, screed automatic tensioning device, the Global Positioning System and road trackers .
