PROBLEM TO BE SOLVED: To provide an electrically raising/lowering device that facilitates a moving operation for raising/lowering an article.SOLUTION: An electrically raising/lowering device comprises: a placing table part 21 on which an article is placed; a raising/lowering actuation part 5 in which one end of an engagement chain 4 is connected to the placing table part 21; a motor part 6 that transmits power to the raising/lowering actuation part 5; a raising/lowering support part 20 supporting and fixing the raising/lowering actuation part 5; weight detecting means 15a to 15d that detect a weight applied to the placing table part 21 and outputs a weight signal; position detecting means 19 that detects a vertical position of the placing table part 21 and outputs a position signal; and a control part 10 that instructs the motor part 6 so that the placing table part 21 is balanced in an arbitrary position in response to a position signal from the position detecting means 19 and a weight signal from the weight detecting means 15a to 15d.SELECTED DRAWING: Figure 2
【課題】物品の昇降移動操作を容易にする電動昇降装置を提供することを課題としている。【解決手段】物品を載せ置く置き台部21と、噛合チェーン4の一端部を置き台部21に接続した昇降作動部5と、昇降作動部5へ動力を伝達するモータ部6と、昇降作動部5を支持固定する昇降支持部20と、置き台部21に印加される重量を検出して重量信号を出力する重量検出手段15a〜dと、置き台部21の上下方向位置を検出して位置信号を出力する位置検出手段19と、位置検出手段19からの位置信号と重量検出手段15a〜dからの重量信号から置き台部21が任意の位置でバランスするようにモータ部6へ指令を行う制御部10とで構成される。【選択図】図2
