388-II
性能特點(diǎn)：
采用高可靠性的液力變矩器和變速箱提供超強(qiáng)動(dòng)力，加重工程專用橋行走平穩(wěn)、可靠性高。
將挖掘機(jī)和裝載機(jī)兩機(jī)合為一體，一機(jī)多能。完全具備小型挖掘機(jī)和裝載機(jī)的所有功能，更適合在狹窄空間作業(yè)，方便靈活，工作效率提高30%以上。
人性化設(shè)計(jì)旋轉(zhuǎn)減振座椅，全鋼化成型玻璃駕駛室，視野更寬闊，駕駛更舒適。
挖掘可側(cè)向滑移機(jī)構(gòu)裝置，使挖掘作業(yè)范圍更大，效率更高。
前翻式護(hù)罩的設(shè)計(jì)，大大提高了整機(jī)的維護(hù)性。
可選配多種附具裝置，完成多種施工作業(yè)。用于市政、建筑、水利、公路、自來(lái)水、供電、園林等部門(mén)，可從事農(nóng)業(yè)建筑，管道鋪設(shè)，電纜敷設(shè)，園林綠化等作業(yè)。
