Description
物品搬送設備10の実施形態について、図面を参照して説明する。図1に示すように、物品搬送設備10は、走行経路12に沿って走行して物品Wを搬送する搬送車20を備えている。ここで、走行経路12の長手方向(走行経路12が延びる方向)を経路長手方向Xとし、走行経路12の幅方向を経路幅方向Yとする。経路幅方向Yは、経路長手方向X及び鉛直方向Zの双方に直交する方向である。経路長手方向Xにおける搬送車20の走行方向の前方側を前方側(下流側)X1とし、経路長手方向Xにおける搬送車20の走行方向の後方側を後方側(上流側)X2とする。図示の例では、後方側X2の搬送車20を搬送車20Aとし、前方側X1の搬送車20を搬送車20Bとして示している。以下、搬送車20Aの構成を中心として説明するが、本実施形態において、搬送車20Aと搬送車20Bとは同じ構成の搬送車である。
