Claims (1)
る長さのクローラ車輪を設けた階段昇降用運搬車
において、 上記クローラ車輪を、荷台後端部下側に配設す
ると共に、このクローラ車輪は、その後端回転部
を中心に前端側が荷台と離れる方向に回動して荷
台の傾斜角度を調節可能に構成したことを特徴と
する階段昇降用運搬車。[Scope of Claim for Utility Model Registration] In a stair-climbing transport vehicle that has crawler wheels long enough to span at least two steps of stairs on the underside of the loading platform, the crawler wheels are arranged below the rear end of the loading platform. In addition, the crawler wheel is configured such that the front end side of the crawler wheel rotates around the rear end rotating portion in a direction away from the loading platform so that the inclination angle of the loading platform can be adjusted.
