前不久,获得日本产业设计振兴会颁发的“优秀设计奖”的住友建机LEGEST系列新型液压挖掘机,又荣获日本经济产业省主办的“节省能源奖”。LEGEST系列高效的节油性能主要得益于其新型“SPACE 5”发动机系统和新型“SIH:S”液压系统,先进系统的有效配合保证了LEGEST系列新型液压挖掘机在降低燃耗20%的同时还将铲斗挖掘力和行走驱动力分别提高了8%和4%,铲斗关闭速度和重挖掘时速度分别增加了24%和7%。新型“SPACE 5”发动机采用高压共轨喷射、带中冷器的涡轮增压以及EGR系统,汽缸内径增大了10mm,功率由
Not long ago, the LEGEST series of new hydraulic excavators, which won the Outstanding Design Award from the Japan Industrial Design Agency, won the Energy Saving Award sponsored by Japan's Ministry of Economy, Trade and Industry. Thanks to its new “SPACE 5” engine system and the new “SIH: S” hydraulic system, the efficient fuel economy of the LEGEST series is complemented by state-of-the-art systems to ensure that the new LEGEST series of hydraulic excavators have the advantage of reducing fuel consumption 20% also increased the digging force and driving force of the bucket by 8% and 4% respectively, while the bucket closing speed and re-excavation speed increased by 24% and 7% respectively. New “SPACE 5” engine with high-pressure common rail injection, intercooler turbocharger and EGR system, the cylinder diameter increased by 10mm, the power from
