樁工機械，主要是指在基礎施(shi)工(gong)(gong)(gong)過程中(zhong)用來(lai)鉆孔(kong)、打樁(zhuang)、壓(ya)(ya)樁(zhuang)的(de)機(ji)械(xie)。這種設(she)(she)備的(de)主要特(te)(te)點專(zhuan)業(ye)性強，生(sheng)產批量較(jiao)小。樁(zhuang)工(gong)(gong)(gong)機(ji)械(xie)液壓(ya)(ya)系統(tong)通常具有較(jiao)高(gao)的(de)壓(ya)(ya)力(li)，這種設(she)(she)備大(da)多(duo)是液壓(ya)(ya)驅(qu)動(dong)(dong)，這樣是為(wei)了保證穩定的(de)施(shi)工(gong)(gong)(gong)。樁(zhuang)工(gong)(gong)(gong)機(ji)械(xie)由(you)于其特(te)(te)殊性，工(gong)(gong)(gong)作環境相對的(de)較(jiao)差，需(xu)(xu)要較(jiao)大(da)的(de)扭矩輸出，需(xu)(xu)要設(she)(she)計較(jiao)大(da)的(de)減(jian)速比結構的(de)液壓(ya)(ya)驅(qu)動(dong)(dong)裝(zhuang)置。
