PROBLEM TO BE SOLVED: To obtain a transportation dolly which moves up a workpiece placed on a load-carrying platform on the dolly to a predetermined position at given timing and returns the load-carrying platform to a predetermined position without using a power source, such as an electric motor, which needs driving control.SOLUTION: A transportation dolly includes: a taking-up drum 9 which takes up a first wire 25; a spring balancer 20 which is provided so as to move on a rail 18, biases a drawable second wire 26 in a take-up direction, and is connected with the first wire; a lifting table 24 which is connected with the second wire and moved up by the second wire being drawn in; a lifting mechanism 3 from which the second wire is suspended, the lifting mechanism moving up or down the lifting table by drawing in or letting off the second wire; and rising lock means 35 which is provided at the lifting mechanism, restricts upward movement of the lifting table, and releases the restriction.

    【課題】電気モータなどの駆動制御の必要な動力源を用いずに、台車上の荷台に載置されたワークを任意のタイミングで所定位置まで上昇させ、且つ荷台を所定の位置に戻すことのできる搬送台車を得ること。【解決手段】第1のワイヤ25を巻き取り可能な巻き取りドラム9と、レール18上を移動自在に設けられ、引き出し可能な第2のワイヤ26を巻き取り方向に付勢すると共に、前記第1のワイヤに接続されたスプリングバランサ20と、前記第2のワイヤに接続され、該第2のワイヤが引き込まれることにより上昇する昇降テーブル24と、前記第2のワイヤが懸架され、該第2のワイヤの引き込みと送り出しにより前記昇降テーブルを昇降移動させる昇降機構3と、前記昇降機構に設けられ、前記昇降テーブルの上昇移動の規制と規制解除とを行う上昇ロック手段35と、を備える。【選択図】図1
