PROBLEM TO BE SOLVED: To eliminate a risk that, in a conventional raised-floor dolly which is expandable and contractive in a width of a cargo-loading platform, its constitution has a safety clutch which operates within only a partially-limited range of a rear side of a traveling operation part, and a worker at the front or rear of the cargo-loading platform may be under-laid below a machine body, and sandwiched between the machine body and a wall.SOLUTION: Clutch levers 8, 9 which can turn on and off a traveling clutch 7 from a front side of a machine body 6, and a clutch connecting part 10 having a gate shape in a front face view which protrudes to a front side of the cargo-loading platform 3 so as to be turnable accompanied by turning operations of the clutch levers 8, 9, or is accommodated into a lower side of the cargo-loading platform 3 are arranged, and an elongation/contraction mechanism E is arranged at a horizontal part 10a of the clutch connecting part 10.SELECTED DRAWING: Figure 1
【課題】従来の荷台幅を拡縮可能な高床運搬車は、走行操作部後方の一部限られた範囲でしか作動しない安全クラッチ装置を設けた構成であり、荷台前方、又は後方の作業者が機体の下敷きになったり、機体と壁の間に挟まれたりする危険性があった。【解決手段】機体6前方から走行クラッチ7を「入」、「切」操作可能のクラッチレバー8,9と、クラッチレバー8,9回動操作に伴い荷台3前方へ回動突出、又は荷台3下側へ収納される正面視門型形状のクラッチ連結部10を設け、クラッチ連結部10の水平部10aに伸縮機構Eを設ける。【選択図】図1
