<p>PROBLEM TO BE SOLVED: To enhance the handleability of an electrically-driven lifting device by enabling a slope to be automatically taken out for storage with an improvement in the operation of a slope plate used to facilitate a movement of a wheeled chair between the lifting base and the lower stage or the upper stage of an electrically-driven lifting device called a step solving machine that enables a wheeled chair seater to easily move between steps.SOLUTION: When a lifting base 10 reaches the side of a lower stage D1, a first link arm 72 moves to a first opening position to make a second link arm 74 moves to a second opening position, so that a slope plate 71 turns downward to automatically open. When a lifting base 10 rises from the lower stage D1, the first link arm 72 moves to a first closing position to make the second link arm 74 moves to a second closing position, so that the first link arm 72 turns upward to automatically close.</p> |
