Provided is a transport trolley capable of mitigating impact on a cargo when the cargo is placed on a cargo table. In a transport trolley (10), a drive device that expands and contracts a telescoping mechanism (70) in the vertical direction by rotation of a motor and raises and lowers a cargo bed (50) has a rear drive property that rotates the motor by expansion and contraction of the telescoping mechanism (70) accompanying raising and lowering of the cargo bed (50) by an external force. The control device detects the lowering of the cargo bed (50) held at a predetermined raising/lowering position and the increase of the load acting on the cargo bed (50) on the basis of output signals from a rotation sensor for detecting the rotation of the motor and a current sensor for detecting the drive current of the motor. The control device controls the motor so that the lowered cargo bed (50) is lifted and held at the predetermined lifting position, or held at a lifting position lower than the predetermined lifting position.

    提供一种能够对载置于货台时货物受到的冲击进行缓和的搬运台车。在搬运台车(10)中,通过电动机的旋转来使伸缩机构(70)在上下方向上伸缩并使货台(50)升降的驱动装置具有通过伴随由外力引起的货台(50)的升降的伸缩机构(70)的伸缩而使上述电动机旋转的后驱动性。在控制装置基于对上述电动机的旋转进行检测的旋转传感器和对上述电动机的驱动电流进行检测的电流传感器的输出信号检测出正保持于规定的升降位置处的货台(50)的下降及作用于货台(50)的负载负荷的增加时,所述控制装置控制上述电动机,以使下降后的货台(50)上升并保持于上述规定的升降位置处、或者保持于比上述规定的升降位置更靠下侧的升降位置处。
