近年来,随着煤炭、有色金属、石油产业的迅速发展,开采规模的扩大,道路的拓宽以及重型运输设备载重吨位的增加,对矿山道路维护的平地机提出了大型、重型的需求趋向,220.5kW以上的平地机更是受到大型露天煤矿的欢迎,显示了良好的需求前景。2013年7月19日,由国机重工旗下鼎盛重工打造的DT660型平地机成功下线,DT660特大型平地机是目前世界动力参数最大的平地机。
In recent years, with the rapid development of coal, non-ferrous metals and petroleum industries, the expansion of mining scale, the widening of roads and the increase of deadweight of heavy-duty transportation equipment, large and heavy demand trends have been put on motor graders for road maintenance. 220.5 More than kW motor grader is even more popular with large opencast mines, showing a good demand outlook. On July 19, 2013, the DT660 grader, which is built by the heavy industry of SINOMACH’s Heavy Industry, successfully got off the ground. The extra large grader DT660 is currently the largest grader in the world.
