PROBLEM TO BE SOLVED: To provide a cargo handling machine capable of performing stable operation.SOLUTION: A control device 28 applies, to the right side of Pud-as=P0+Wud/(1+s*A/g)*h, a weight Wud during acceleration measured by a load sensor 12 and an acceleration vertical component A measured by an acceleration sensor 11 that are respectively provided in a holding device 7, a non-load balance pressure P0 and a proportional constant h that are respectively measured in advance, and an auxiliary force adjustment constant s stored in a storage device 31. The thus-obtained adjustment balance pressure Pud-as during acceleration is set to the pressure of a cylinder chamber 23. The adjustment balance pressure Pud-as during acceleration is closer to the balance pressure Pus in standstill than the balance pressure Pud during acceleration, so that the operation of a cargo handling machine 1 becomes stable.SELECTED DRAWING: Figure 2

    【課題】安定な動作ができる荷役機械を提供する。【解決手段】制御装置28は、保持装置7にそれぞれ設けられた荷重センサ12が測定した加速時重量Wudと加速度センサ11が測定した加速度鉛直成分Aと、予めそれぞれ測定しておいた無負荷バランス圧P0と比例定数hと、記憶装置31に記憶された補助力調整定数sとをPud-as=P0+Wud/(1+s・A/g)・hの右辺に適用し、求めた加速時調整バランス圧Pud-asをシリンダ室23の圧力にする。加速時調整バランス圧Pud-asは加速時バランス圧Pudよりも静止時バランス圧Pusに近い値になり、荷役機械1の動作が安定する。【選択図】図2
