樁工機械，主要(yao)(yao)是指在基礎施工(gong)(gong)過程(cheng)中用來鉆孔、打樁(zhuang)、壓(ya)(ya)樁(zhuang)的機(ji)械。這種設備的主要(yao)(yao)特點專業(ye)性(xing)強，生產(chan)批量較小。樁(zhuang)工(gong)(gong)機(ji)械液(ye)(ye)壓(ya)(ya)系統通常具有較高的壓(ya)(ya)力，這種設備大(da)(da)多是液(ye)(ye)壓(ya)(ya)驅(qu)動，這樣是為了保(bao)證穩定的施工(gong)(gong)。樁(zhuang)工(gong)(gong)機(ji)械由于(yu)其特殊性(xing)，工(gong)(gong)作環境(jing)相對的較差，需(xu)要(yao)(yao)較大(da)(da)的扭矩(ju)輸出，需(xu)要(yao)(yao)設計(ji)較大(da)(da)的減速比結構的液(ye)(ye)壓(ya)(ya)驅(qu)動裝置。
