An article transport facility is provided with a plurality of transport vehicles, a first travel track, a second travel track disposed below the first travel track, a lifting device having a lifting track, and a control system. When the control system receives a preceding request signal from the target transport vehicle, the control system executes a pre-lifting process for moving the lifting rail to the target position on one of the conditions that no non-target transport vehicle is present on the lifting rail and no entry request signal is received from the target transport vehicle. 一种物品输送设备具备多个输送车、第1行驶轨道、配置于比第1行驶轨道更靠下侧处的第2行驶轨道、具有升降轨道的升降装置以及控制系统。控制系统在从对象输送车接收到先行请求信号的情况下，以在升降轨道上不存在非对象输送车且未非从对象输送车接收到进入请求信号为条件之一，执行使升降轨道移动至对象位置的事先升降处理。
