It is typically mounted on the back of a tractor or front loader, the latter forming a "backhoe loader" (a US term, but known as a "JCB" in Ireland and the UK). The section of the arm closest to the vehicle is known as the boom, while the section that carries the bucket is known as the dipper (or dipper-stick), both terms derived from steam shovels.

挖掘機，专业术语液压挖掘机，有正铲和反铲两种，一般通常见到是液压反铲挖掘机，适应于平常的建筑工地及工程施工，而液压正铲挖掘机则一般适应于大型矿山开挖装卸。臺灣称“鏟斗機”，俗稱雞頭或反鏟。因其多工性，為建築工程最常見的機械之一。挖掘機機身下盤為履帶車輪，上盤為動力機身，前裝固定桁架，架上裝置鏟臂，可以俯仰，鏟臂前端為鏟斗，作業時，將鏟斗貼向地層，以鏟臂施力向前鏟挖，土方即進入斗內，機身旋轉，使鏟斗就棄土位置，將鏟斗底蓋開啟，土方即自行卸落，完成一次鏟行為。鏟斗作業早期為鋼索駛動，機體行走為柴油引擎。挖掘機適於平地山坡土壤、軟岩及爆鬆後之岩石等挖方。 下盤履帶車輪令挖掘機可行走於不良地面，可用以壓實地面。上盤機械臂可接上不同的部件，如鏟斗，可挖土。
