To improve safety and operability of a cargo handling assistance device mounted with a balance function to perform a moving work of cargoes.SOLUTION: The cargo handling assistance device has: a locking member 8 to lock cargoes 30 to be lifted and lowered; a lifting/lowering operation unit to lift and lower the locking member 8 by feeding a chain or a rope; a motor unit of a driving source connected to the lifting/lowering operation unit; a weight detection unit to detect a weight applied to the lifting/lowering operation unit; a position detection unit to detect a feeding position of the locking member 8; a control unit 10 to issue a command to the motor unit on the basis of a position signal from the position detection unit and a weight signal from the weight detection unit; and an operation command unit 22a to issue a command related to the lifting/lowering of the locking member 8 to the control unit. The control unit 10 limits the feeding length of the locking member 8 to equal to or less than a first length L1 capable of presetting variably, when the control unit 10 detects that the weight sum of the locking member 8 and the cargoes 30 is applied to the weight detection unit and controls the motor unit so as to keep the balance of the cargoes 30.SELECTED DRAWING: Figure 3
【課題】荷役物の移動作業を行うバランス機能が搭載された荷役助力装置における安全性、操作性の改善を目的としている。【解決手段】昇降させる荷役物30を係止する係止部材8と、係止部材8をチェーン若しくはロープで繰出して昇降を行う昇降作動部と、昇降作動部と繋がっている駆動源のモータ部と、昇降作動部に加わる重量を検出する重量検出部と、係止部材8の繰出し位置を検出する位置検出部と、位置検出部からの位置信号と重量検出部からの重量信号に基いてモータ部へ指令を行う制御部10と、係止部材8の昇降に係る指令を制御部へ行う操作指令部22aと、を有した荷役助力装置であって、制御部10が、重量検出部に係止部材8と荷役物30の重量の和が加わっていることを検出して荷役物30をバランスするようにモータ部を制御している時、制御部10は係止部材8の繰出し長さを予め可変設定可能な第1の長さL1以下に制限する。【選択図】図3
