Abstract
A conveyance device includes a traveling vehicle, a mast, a raising and lowering section, and a control section. The traveling vehicle includes a wheel, a motor which drives the wheel, and a slippage detection section which detects slippage at the wheel. In a case where two or more slippage detection sections out of the slippage detection sections detect, at least in a state where the traveling vehicle is accelerated, slippage of not less than a predetermined amount, the control section causes the traveling vehicle to stop.
