To inhibit occurrence of abnormal noise caused at the time of start of movement of a load receiving platform when the load receiving platform is pulled out.SOLUTION: A retractable load receiving platform lifter pulls in a load receiving platform to the lower side of a frame to store the load receiving platform and is provided with: a lift cylinder which moves up or down the load receiving platform; a slide cylinder which moves the load receiving platform in a fore and aft direction; a lifting control valve which controls flow of hydraulic oil to the lift cylinder; a slide control valve which controls flow of the hydraulic oil to the slide cylinder; and a control device which controls the lifting control valve and the slide control valve. The control device is configured to command the slide control valve to conduct an extension operation of the slide cylinder and concurrently command the lifting control valve to conduct an extension operation of the lift cylinder when the load receiving platform is pulled out from the lower side of the frame.SELECTED DRAWING: Figure 13

    【課題】荷受台を引き出す際の動き始めの異音の発生を抑制する。【解決手段】荷受台を車枠の下側に引き込んで格納する格納式荷受台昇降装置において、荷受台を昇降させるリフトシリンダと、荷受台を前後に移動させるスライドシリンダと、リフトシリンダへの作動油の流れを制御する昇降制御弁と、スライドシリンダへの作動油の流れを制御するスライド制御弁と、昇降制御弁及びスライド制御弁を制御する制御装置を設け、制御装置が、車枠の下側から荷受台を引き出す際、スライド制御弁にスライドシリンダの伸長動作を指令すると同時に、昇降制御弁にリフトシリンダの伸長動作を指令するように構成する。【選択図】図13
