PROBLEM TO BE SOLVED: To provide a retractable cargo receiving base lifting device capable of restraining reduction in smoothness of storage operation of a cargo receiving base resulting from occurrence of an unnecessary re-lifting operation.SOLUTION: A retractable cargo receiving base lifting device 4 comprises a cargo receiving base 5, a slider 9 which moves along a guide rail 8 provided in a lower part of a vehicle, a slide cylinder 14 for moving the slider 9, arms 17-19 liftably connecting the cargo receiving base 5 relative to the slider 9, and a lift cylinder 20 for lifting and lowering the cargo receiving base 5. The retractable cargo receiving base lifting device 4 comprises a gate sensor 56 for detecting a vertical position of the cargo receiving base and a control device 45 for controlling the lift cylinder 20 and the slide cylinder 14. When storing the cargo receiving base 5, the control device 45 lifts the cargo receiving base 5 to an intermediate area in a set height range by continuously driving the lift cylinder 20 for set time T0 from a time when it is detected that the cargo receiving base 5 has reached a lower limit of the set height range based on a signal from the gate sensor 56, after which pulls in the cargo receiving base 5 by driving the slide cylinder 14.SELECTED DRAWING: Figure 15

    【課題】不要な再上昇動作の発生による荷受台の格納動作の円滑性の低下を抑制できる格納式荷受台昇降装置を提供する。【解決手段】荷受台5、車両の下部に設けたガイドレール8に沿って移動するスライダ9、スライダ9を移動させるスライドシリンダ14、スライダ9に対して荷受台5を昇降可能に連結するアーム17−19、荷受台5を昇降させるリフトシリンダ20を備えた格納式荷受台昇降装置4において、荷受台の鉛直方向位置を検出するゲートセンサ56と、リフトシリンダ20及びスライドシリンダ14を制御する制御装置45を備え、荷受台5を格納する際、制御装置45は、荷受台5が設定の高さ範囲の下限に到達したことがゲートセンサ56の信号を基に検知された時点から設定時間T0だけリフトシリンダ20を継続して駆動して荷受台5を上記設定の高さ範囲の中間域まで上昇させた後、スライドシリンダ14を駆動して荷受台5を引き込む。【選択図】図15
