目前应用较多的牵引式液压刨式平地机．存在着作业类型单一．在平地过程中受力不均匀．横梁的刚性较差等缺年．为此可作以下改进。至横梁加焊钢板现用的刨式平地机都是采用20“槽钢作横梁．槽钢是有一个面不封闭．使用中受力具有方向性．由于大梁较长，且受力较大．往往易出现大 At present, more traction hydraulic planing machine. There is a single type of job. Uneven force in the process of leveling. Poor rigidity of beams and other short years. To this end can make the following improvements. To the beam welding plate are now used planing grader 20 ”channel for the beam. Channel is a surface is not closed. Used in force with the direction of .Because the beam is longer, and the force is larger Often prone to big
