独轮车是一个以人力推动的小型运载工具，最早为希腊人或中国汉朝人发明。它符合工效学，能够抵受在崎岖路面行进，但是不能在太过倾斜的地面作物资或工具运输。

独轮车利用杠杆原理而把负载的抗力点的靠近支点（即车轮）而令本身运作有效率，亦把负载分担在独轮车及操纵者之上。因为独轮车令笨重或大量的负载移动变得轻松，所以它在建筑工地、农地、花园中都是不可或缺的。

虽然两轮的手推车在平地较为稳定，但独轮车则在易失平衡的地方如细小、铺板或翘起的路面有较高的可操作性，而且在卸载时亦较易控制。

A wheelbarrow is a small hand-propelled vehicle, usually with just one wheel, designed to be pushed and guided by a single person using two handles at the rear, or by a sail to push the ancient wheelbarrow by wind. The term "wheelbarrow" is made of two words: "wheel" and "barrow." "Barrow" is a derivation of the Old English "bearwe" which was a device used for carrying loads.
