To improve operability in a loading assistance device which balances a loaded article while regulating a lifting track and proving slidable guiding on a multistage slide rail.SOLUTION: This loading assistance device comprises: a locking member 11 that locks a loaded article 12 to be lifted; a lifting operation unit 25 that delivers the locking member 11 by means of a chain 8 and lifts the locking member 11; a multistage slide rail 5 for regulating a lifting track of the locking member 11 at at least three or more stages and slidably guiding the locking member; a driving source motor 20 that is connected to the lifting operation unit 25; a weight detection unit that detects weight applied to the lifting operation unit 25 and outputs a weight signal; a position detection unit 21 that detects the delivery position of the locking member and outputs a position signal; and a control unit 23 that instructs the motor 20 on the basis of the position signal and the weight signal. The control unit 23 executes balance control by adding/subtracting a prescribed value to/from the weight applied to the lifting operation unit 25 in accordance with a section S defined on the basis of the delivery position of the locking member 11.SELECTED DRAWING: Figure 7
【課題】多段スライドレールによって昇降の軌道を規制して摺動自在に案内しつつ荷役物をバランスさせる荷役助力装置において、操作性の向上を課題としている。【解決手段】昇降させる荷役物12を係止する係止部材11と、係止部材11をチェーン8で繰出して係止部材11の昇降を行う昇降作動部25と、少なくとも3段以上で係止部材11の昇降の軌道を規制しつつ摺動自在に案内する多段スライドレール5と、昇降作動部25と繋がっている駆動源のモータ部20と、昇降作動部25に加わる重量を検出して重量信号を出力する重量検出部と、係止部材の繰出し位置を検出して位置信号を出力する位置検出部21と、位置信号と重量信号に基いて、モータ部20へ指令を行う制御部23と、を有した荷役助力装置であって、制御部23は、係止部材11の繰出し位置によって定めた区間Sに応じて、昇降作動部25に加わる重量に所定値を加減してバランス制御を実行する。【選択図】図7
