To provide a carrying truck capable of mitigating the impact applied on a load when the load is placed on a loading space.SOLUTION: In a carrying truck 10, a driving device expanding/contracting an expansion mechanism 70 in a vertical direction by rotation of an electric motor to lift/lower a loading space 50, has back drive performance in which the electric motor is rotated by the expansion/contraction of the expansion mechanism 70 accompanying the lifting/lowering of the loading space 50 due to external force. When the lowering of the loading space 50 held at a prescribed lifting/lowering position and the increase in a load acting on the loading space 50 are detected based on output signals of a rotation sensor for detecting the rotation of the electric motor and a current sensor for detecting a driving current of the electric motor, a control device controls the electric motor so as to lift and hold the lowered loading space 50 at the prescribed lifting/lowering position or hold the loading space at a lifting/lowering position lower than the prescribed lifting/lowering position.SELECTED DRAWING: Figure 17

    【課題】荷台に載置されるときに荷物が受ける衝撃を緩和することのできる運搬台車を提供する。【解決手段】運搬台車10において、電動モータの回転によって伸縮機構70を上下方向に伸縮させて荷台50を昇降させる駆動装置は、外力による荷台50の昇降に伴う伸縮機構70の伸縮によって前記電動モータが回転するバックドライブ性を有する。制御装置は、前記電動モータの回転を検出する回転センサ及び前記電動モータの駆動電流を検出する電流センサの出力信号に基づいて所定の昇降位置で保持中の荷台50の下降及び荷台50に作用する荷重負荷の増加を検知すると、下降した荷台50を上昇させて前記所定の昇降位置で保持するか又は前記所定の昇降位置よりも下側の昇降位置で保持するように前記電動モータを制御する。【選択図】図17
