To reduce the capacity of a drive unit in a lower-drive type article elevating/lowering device.SOLUTION: A carriage C and counterweight CW are suspended in a well bucket manner by suspension chains 2, 3 that engage upper driven sprockets 6A-6C located at the top of an article elevating/lowering device 1. One end 4A of a drive chain 4, which engages a drive sprocket 5 located at the bottom of the article elevating/lowering device 1, is connected to a lower end 2A of the suspension chain 2 that suspends the carriage C, and the other end 4B of the drive chain 4 is connected to the counterweight CW. The drive sprocket 5 is driven by a drive device D to elevate and lower the carriage C and the counterweight CW. A carriage-side take-up device TU1 is provided on the drive chain 4 between the drive sprocket 5 and the carriage C, and a counterweight-side take-up device TU2 is provided on the drive chain 4 between the drive sprocket 5 and the counterweight CW.SELECTED DRAWING: Figure 2

    【課題】下駆動方式の物品昇降装置において駆動装置の容量を小さくする。【解決手段】物品昇降装置1の上部に配置した上部従動スプロケット6A~6Cに係合する吊り下げチェーン2,3により、キャリッジCとカウンターウェイトCWを釣瓶式に吊り下げる。物品昇降装置1の下部に配置した駆動スプロケット5に係合する駆動チェーン4の一端4AをキャリッジCを吊り下げる吊り下げチェーン2の下端2Aに繋げ、駆動チェーン4の他端4BをカウンターウェイトCWに繋げる。駆動スプロケット5を駆動装置Dにより駆動してキャリッジC及びカウンターウェイトCWを昇降させる。駆動スプロケット5とキャリッジCとの間の駆動チェーン4にキャリッジ側テークアップ装置TU1を設け、駆動スプロケット5とカウンターウェイトCWとの間の駆動チェーン4にカウンターウェイト側テークアップ装置TU2を設ける。【選択図】図2
