To provide a conveyance dolly that is able to easily lift a conveyor without using a power source such as electricity or air.SOLUTION: A conveyance dolly 1 includes a conveyor 3 and a lifting/lowering device 4 that lifts/lowers the conveyor 3. A lifting device 4 has: a rolling wheel 10 of ratchet 17 type, which rolls on a surface of a floor F as a dolly body 2 travels; a cable 14 wound up on the rolling wheel 10 to pull up the conveyor 3; a compound pulley 20 mounted at a certain point of wiring of the cable 14, the compound pulley 20 consisting of a combination of a fixed pulley 21 mounted on the dolly body 2 and a movable pulley 22 mounted on the conveyor 3; a disconnection mechanism 62 that is pushed by the conveyor 3 to pull and separate the rolling wheel 10 from the surface of the floor F; a releasing mechanism 70 that releases a reverse rotation preventing state of the rolling wheel 10 to lower the conveyor 3; and a restoring mechanism 61 of foot pedal 61a type that grounds the rolling wheel 10 into a state of reverse rotation prevention on the surface of the floor F from a state of being separated from the surface of the floor F.SELECTED DRAWING: Figure 8

    【課題】電気又はエア等の動力源を用いずにコンベヤを容易に持ち上げられる運搬台車を提供すること。【解決手段】運搬台車1は、コンベヤ3とコンベヤ3を昇降させる昇降装置4とを備える。昇降装置4が、台車本体2の走行に伴いフロアF上を転動するラチェット17式の転動輪10と、転動輪10に巻き取られてコンベヤ3を引き上げるケーブル14と、ケーブル14の配索途中に掛けられる複滑車20であって台車本体2に取り付けられる定滑車21とコンベヤ3に取り付けられる動滑車22との組み合わせから成る複滑車20と、コンベヤ3に押し動かされて転動輪10をフロアF上から引き離す遮断機構62と、転動輪10の逆転止め状態を解除してコンベヤ3を下降させる解除機構70と、転動輪10をフロアF上から引き離された状態からフロアF上に逆転止めした状態として接地させるフットペダル61a式の復帰機構61と、を有する。【選択図】図8
