自動扶梯是帶有循環運行梯級，用于向上或向下傾斜輸送乘客的固定電力驅動設備。

自動扶梯由梯路（變型的板式輸送機）和兩旁的扶手（變形的帶式輸送機）組成。其主要部件有梯級、牽引鏈條及鏈輪、導軌系統、主傳動系統（包括電動機、減速裝置、制動器及中間傳動環節等）、驅動主軸、梯路張緊裝置、扶手系統、梳板、扶梯骨架和電氣系統等。梯級在乘客入口處作水平運動（方便乘客登梯），以后逐漸形成階梯；在接近出口處階梯逐漸消失，梯級再度作水平運動。這些運動都是由梯級主輪、輔輪分別沿不同的梯級導軌行走來實現的。

    An escalator is a fixed, electrically powered device equipped with continuously circulating steps, designed for inclined transportation of passengers upwards or downwards.

    It consists of a step pathway (a modified slat conveyor) and handrails on both sides (modified belt conveyors). Its main components include steps, traction chains and sprockets, guide rail systems, main drive systems (including electric motors, reduction gearboxes, brakes and intermediate transmission components, etc.), drive spindles, step pathway tensioning devices, handrail systems, comb plates, escalator trusses and electrical systems.At the passenger entrance, the steps move horizontally (to facilitate passenger boarding), then gradually form staircases; near the exit, the staircases gradually flatten out and the steps resume horizontal movement. All these movements are achieved by the main and auxiliary wheels of the steps traveling along different step guide rails respectively.
