PROBLEM TO BE SOLVED: To reduce power consumption of an electrical lifting device which lifts goods up and down with small force by balancing weights of the goods to be lifted up and down at an arbitrary position.SOLUTION: An electrical lifting device comprises: a holding member (a pedestal section 21) which holds goods 60 to be lifted up and down; a lifting action section 5 which lifts up and down the pedestal section 21; a motor section 6 which includes a reduction gear to drive the lifting action section 5; weight detection means 15a to 15d which outputs weight signals by detecting a weight loaded on the pedestal section 21; position detection means 19 which outputs a positional signal by detecting a lifting position of the pedestal section 21; a control section 10 which controls so as to balance the pedestal section 21 at an arbitrary position on the basis of the positional signal and the weight signals; and an operation section 13 which is connected to the control section 10 and instructs operation related to lifting the goods up and down. When lifting the pedestal section 21 vertically upward to hold the same at a desired position, the control section 10 controls in a manner that the pedestal section 21 is lifted from a desired position by a predetermined distance in a vertically upward direction and, then, the pedestal section 21 is lowered to be held at the desired position.SELECTED DRAWING: Figure 2

    【課題】昇降させる物品を任意の位置でバランスさせ、小さな力で昇降移動させる電動昇降装置の消費電力を低減することを課題としている。【解決手段】昇降させる物品60を係止する係止部材(置き台部21)と、置き台部21の昇降を行う昇降作動部5と、昇降作動部5を駆動する減速機を含んだモータ部6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〜15dと、置き台部21の昇降位置を検出して位置信号を出力する位置検出手段19と、位置信号と重量信号に基づき、置き台部21が任意の位置にてバランスするように制御を行う制御部10と、制御部10と繋がって昇降に係る指令を行う操作部13と、を備え、制御部10は、置き台部21を鉛直上方向の所望の位置に移動させて保持させる時、置き台部21を所望の位置から所定量だけ鉛直上方向へ移動させた後、所望の位置まで移動させて保持するように制御する。【選択図】図2
