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
