To suppress a collision noise generated when a load support is retracted into a lower part of a frame.SOLUTION: A position, in which a slider abuts on a stopper, in a movable range of a load support by a slide cylinder is defined as a front end position, and a set position between a back end and the front end position of the movable range is defined as an intermediate position. When the load support is retracted, the slide cylinder is controlled (S211) so that the slider can abut on the stopper at a pull-in speed lower than a speed of a load support pull-in operation (S207) in the case where the load support is located in a position further away from the front end position than the intermediate position.SELECTED DRAWING: Figure 15
【課題】車枠の下部に荷受台を格納する際の衝突音を抑制する。【解決手段】スライドシリンダによる荷受台の可動範囲のうちストッパにスライダが当たる位置を前端位置、上記可動範囲の後端と前端位置との間の設定位置を中間位置と定義して、荷受台を格納する際、中間位置よりも前端位置から離れた位置に荷受台がある場合の荷受台の引込動作(S207)よりも遅い引込速度でストッパにスライダが当たるようにスライドシリンダを制御する(S211)。【選択図】図15
