To provide a device which enables a heavy object in a range which can be handled in transportation by human work to be moved up or down instantly.SOLUTION: A loading platform 1 disposed at the front of a dolly and a step board 3 for moving up the loading platform are respectively fixed to a linear guide component 2 and a linear guide component 4 which are fixed to a support pillar 5 serving as a framework of the dolly. A pulley 6 is fixed to an upper end of the support pillar. One end of one wire 7 is fixed to the loading platform, and the other end goes around the pulley to be fixed to the step board. The loading platform and the step board may move vertically while keeping a horizontal state. Making the loading platform heavier than the step board causes the loading platform to be in a stand-by state at a lower limit position where the loading platform is in contact with a landing part 15 at normal times, and a package can be instantly moved up only by a worker putting his/her weight on the step board. Further, a lever 8 which is swung by a spring is fixed to a support pillar side surface. At a descent end of the step board, action of the spring causes the lever to protrude to an upper part of the step board to prevent the step board from moving up and thereby keep the loading platform at the opposite side of the pulley in an elevated position.SELECTED DRAWING: Figure 1
【課題】人手による搬送で扱われる範囲の重量物を、瞬時に昇降可能にする装置を提供する。【解決手段】台車の前方に配置した荷台1と、荷台を上昇させるための踏み台3とを、台車の骨格である支柱5に固定した、直線ガイド部品2および直線ガイド部品4に固定する。支柱の上端には滑車6を固定し、1本のワイヤー7の片端を荷台に固定し、他端を滑車を周回して踏み台に固定する。荷台と踏み台は、水平状態を保って上下移動が可能となる。荷台を踏み台より重く設定することにより、常時は荷台が着地部品15に当接した下限位置で待機状態となり、踏み台に作業者が体重を掛けるだけで、瞬時に荷物を上昇させることが可能となる。さらに支柱側面にバネで搖動可能になるレバー8を固定し、踏み台の下降端で、レバーが踏み台上部にバネの作用ではみ出して、踏み台の上昇を抑えることにより、滑車の反対側の荷台が上昇位置で保持される。【選択図】図1
