PROBLEM TO BE SOLVED: To provide a bridge that can achieve a travelling surface thereof longer than a length of a rear deck of a truck so as to allow an inclination angle of the travelling surface gentle at the time of installation thereof, and eliminates an uneasy feeling of a worker for work for loading/unloading a cargo onto/from a rear deck of a vehicle to be loaded with a cargo to enable the worker to surely and safely perform the work for loading and unloading and the like.SOLUTION: The bridge is divided into a main body-side bridge and a grounding-side bridge at a gap part between a pair of left and right frame members, the grounding-side bridge is connected to a step material to be foldable in a reverse-travelling surface direction of the material, the whole lengths of both brides are set to be longer than a longitudinal length of a rear deck of a truck in a state where the bridges are not folded back, and both bridges are configured so as to be loaded onto the rear deck of the truck in a state where the brides are folded back. Fixing members that lock and fix the grounding-side bridge in a folded-back state to a rear-deck side bridge are arranged on reverse-travelling surface, for instance, of the bridges respectively, and the fixing members are attached to and detached from each other by elasticity thereof.SELECTED DRAWING: Figure 1
【課題】トラックの荷台の長さよりも長い走行面が得られて設置時の走行面の傾斜角度を緩くでき、被搭載車両の荷台への積み下ろし作業に対する作業者の不安感を解消して、確実かつ安全な積み下ろし作業等を可能にするブリッジを提供する。【解決手段】左右一対のフレーム材の間隙部分で本体側ブリッジと接地側ブリッジに分割され、接地側ブリッジがステップ材の反走行面方向に折り畳み可能に連結され、非折り畳み状態において両ブリッジの全長がトラックの荷台の前後の長さより長く設定されると共に、折り畳み状態において両ブリッジがトラックの荷台に積載可能に構成されていることを特徴とする。各ブリッジの例えば反走行面に、折り畳んだ状態の接地側ブリッジを荷台側ブリッジに係止固定する固定部材がそれぞれ配設され、各固定部材は、その弾性により互いに着脱される。【選択図】 図1
