To provide an unmanned carrier that travels under a vehicle and hauls the vehicle in a state where a pair of wheels of the vehicle are raised from a floor, and has a more reduced height.SOLUTION: A top plate 8 and a vehicle body 2 are so connected by lifters 10a, 10b and 10c so that the top plate 8 may be elevated and lowered and a top face 8b of the top plate 8 in the most lowered state may be at the almost same level as a top face 2bu of a swollen part 2b of the vehicle body 2. Lifter levers 12a, 12b, 12c and 12d to raise front wheels Wfr and Wfl of a vehicle Car from a floor f are so supported under a lower face of the top plate 8 as to be able to rotate (fluctuate) in a horizontal plane. This arrangement can suppress a location of the top plate 8 low in a height direction. Because the lifter levers 12a, 12b, 12c and 12d are not placed on the top face 8b of the top plate 8, the vehicle height of an unmanned carrier 1 is reduced more.SELECTED DRAWING: Figure 29
【課題】車両の下側に入り込み、一対の車輪を床から持ち上げた状態で車両を牽引する無人搬送車において、車高のより一層の低減を図ること。【解決手段】天板8を昇降可能、かつ、下降しきった状態の天板8の上面8bが車体2の膨出部2bの上面2buとほぼ同じ高さとなるように、天板8と車体2とをリフター10a,10b,10cによって接続する。そして、車両Carの前輪Wfr,Wflを床fより持ち上げるためのリフターレバー12a,12b,12c,12dが、天板8の下面に水平面内で回動(搖動)可能に支持される。これにより、天板8の高さ方向における配置を低く抑えることができる。また、リフターレバー12a,12b,12c,12dが天板8の上面8bに配置されないため、無人搬送車1の車高をより一層低減することができる。【選択図】図29
