PROBLEM TO BE SOLVED: To provide a storage type load receiving platform lifting device capable of achieving quiet operation when a state of being stored in a lower part of a vehicle frame is shifted to a usable state.SOLUTION: A storage type load receiving platform lifting device 4 which pulls in and stores a load receiving platform 5 in a lower part of a vehicle frame 1, comprises: a slider 9 which is connected to the load receiving platform and moves along a guide rail 8 fitted to the vehicle frame; a slide cylinder 14 which moves the slider along the guide rail; a stopper 75 which restricts a rear end of a moving range of the slider; a rear end sensor 15 which detects that a space between the stopper and the slider is equal to or less than a set distance L; and a control unit 45 which controls operations of a lift cylinder and the slide cylinder. The control unit decelerates an extension speed of the slide cylinder from first speed to second speed when the space between the stopper and the slider becomes L or less when pulling out the load receiving platform, and extends the slider cylinder at the second speed until the slider abuts on the stopper after the space becomes L or less.SELECTED DRAWING: Figure 7

    【課題】車枠の下部に格納された状態から使用可能な状態に移行させる際の動作の清音化をする。【解決手段】荷受台5を車枠1の下部に引き込んで格納する格納式荷受台昇降装置4において、荷受台に連結され、車枠に取り付けたガイドレール8に沿って移動するスライダ9と、スライダをガイドレールに沿って移動させるスライドシリンダ14と、スライダの移動範囲の後端を制限するストッパ75と、ストッパとスライダの間隔が設定距離L以下であることを検出する後端センサ15と、リフトシリンダ及びスライドシリンダの動作を制御する制御装置45を備え、制御装置は、荷受台の引き出し時、ストッパとスライダの間隔がL以下になる際にスライドシリンダの伸長速度を第1速度から第2速度に減速させ、間隔がL以下になってからスライダがストッパに当たるまで第2速度でスライドシリンダを伸長させる。【選択図】 図7
