To provide a cargo handling assistance device whose operability is improved in cargo handling work in the case where unintended external force acts on a cargo.SOLUTION: A cargo handling assistance device 1 includes a locking member 6 for locking a cargo, a lifting/lowering operation part 16 for lifting/lowering the locking member 6 by a link chain 4, a motor part 11 of a driving source, a weight detection part 12 for detecting the weight applied to the lifting/lowering operation part 16, a position detection part 13 for detecting a feeding position of the locking member 6, a control unit 10 for issuing a command to the motor part 11 based on a position signal and a weight signal, and an operation command unit 9 for issuing an operation command. The control unit 10 includes means for storing the weight in the case where a cargo is in a suspended state as a registered weight, means for receiving the position signal to be stored as a first position when a reciprocative lifting/lowering command is received and the weight is less than the registered weight, and means for executing reciprocative lifting/lowering movement between the first position and a second position based on the weight signal after the cargo is moved up to reach the second position.SELECTED DRAWING: Figure 2
【課題】荷役物に意図しない外力が働く場合の荷役作業において、操作性の改善を図った荷役助力装置の提供を課題としている。【解決手段】荷役物を係止する係止部材6と、係止部材6をリンクチェーン4にて昇降を行う昇降作動部16と、駆動源のモータ部11と、昇降作動部16に加わる重量を検出する重量検出部12と、係止部材6の繰り出し位置を検出する位置検出部13と、位置信号と重量信号に基いてモータ部11へ指令を行う制御部10と、操作指令を行う操作指令部9と、を有する荷役助力装置1であって、 制御部10が、荷役物が宙吊り状態となった時の重量を登録重量として記憶する手段と、往復昇降指令を受信してかつ重量が登録重量未満であった時、位置信号を受信して第1の位置として記憶する手段と、重量信号を基にした第2の位置に到達するまで上昇させた後、第1の位置と第2の位置とで往復昇降繰り返しを実行する手段と、を有する。【選択図】図2
