近几年来,由于国内交通运输业的飞速发展,对公路建筑的质量要求越来越高,筑路行业迫切需要大吨位的压路机,我厂从1982年开始,对国内外现型静碾压路机进行了分析比较,研制出国内外没有过的大吨位压路机—3Y18/20型静碾光轮压路机。该机加载后驱动轮的线压力高达115公斤/厘米,是一种超重型的压路机。样机于1982年试制成功,经整机性能试验、压实试验和工业性考核共计2000小时后进行解体检查,从试验和检查数据看都达到了设计要
In recent years, due to the rapid development of the domestic transportation industry, the quality requirements for highway construction have become higher and higher. The road building industry is in urgent need of large-tonnage road rollers. Since 1982, our factory has carried out the development of static type roller compactors at home and abroad. Analyzed and compared, the large-tonnage roller 3Y18/20 static roller roller compactor that was not developed at home and abroad was developed. After the machine is loaded, the line pressure of the driving wheel is as high as 115 kg/cm. It is an extremely heavy-duty roller. The prototype was successfully tested in 1982. After a total of 2000 hours of performance tests, compaction tests, and industrial assessments, the prototype was disassembled. From the test and inspection data, the design was completed.
