目前挖掘机的混合动力技术路线主要分油电混合和液压混合,但基本原理是相同的。小松是油电混合路线的代表,不过无论哪种路线,目前仍处于市场培育的阶段,产品普及和型号发展相对较慢,产品仍在持续改进之中。2008年,小松开创性地引入了20t级的混合动力挖掘机PC200-8E0,后在2010年升级为HB205/HB215-1,使得挖掘机进入了混合动力时代,当然,尽管技术上很先进,效果也很好,毕竟是新技术,推广和大规模应用需要一个过程,小松只能稳步将该技术延伸到其他吨位。
The current excavator hybrid technology route is mainly divided into oil and electricity hybrid and hydraulic mix, but the basic principle is the same. Komatsu is the representative of the mixed line of oil and gas, but no matter what route is currently in the stage of market cultivation, product development and model development is relatively slow, the product is still under continuous improvement. In 2008, Komatsu pioneered the introduction of the 20t class hybrid excavator PC200-8E0, after upgrading to HB205 / HB215-1 in 2010, making the excavator into the hybrid era, of course, although technically advanced, the effect It’s also good, after all, a process that requires new technology, promotion and mass adoption, and Komatsu can only steadily extend the technology to other tonnage.
