To provide a step for raising and lowering a track capable of folding right and left handrails from a use state to an unused state merely by an operator easily operating with one hand.SOLUTION: A step for raising and lowering a track capable of releasing fixation of a handrail in a standing state, by operating a coupling tool, provided with a pair of right and left support columns, a plurality of step boards horizontally disposed between the support columns, a top board horizontally disposed on the upper end portion of the support columns, and a handrail attached to the support columns, respectively, wherein one end of the top board is connected to an upper end portion of the support columns by angle fixing means that can be fixed at different angles, and locking means for locking the top board in a tailgate of a truck deck is provided at a lower end of the top board, the handrail is pivotally supported by a pivotal portion disposed above and below the support columns so as to be capable of being displaced in a state of being erected perpendicular to the support columns and a state of being folded parallel to the support columns, and fixing means for fixing the raised state of the handrail is provided on the pivotal portion, and the fixing means respectively provided on the pivotal portion is connected by a connecting tool.SELECTED DRAWING: Figure 5
【課題】作業者が片手で容易に操作するだけで、使用状態から未使用状態に左右の手摺を折り畳めるトラック昇降ステップを提供する。【解決手段】左右一対の支柱と、支柱間に横架された複数の踏板と、支柱の上端部に横架された天板と、支柱にそれぞれ取り付けられた手摺と、を備え、天板の一端は、支柱の上端部に異なる角度で固定可能な角度固定手段により連結され、前記天板の多端下部には、当該天板をトラックの荷台のあおりに係止する係止手段が設けられ、手摺は、支柱の上下に配設された軸支部により、支柱に対して垂直に起立した状態と平行に折り畳まれた状態とに変位可能に軸支され、軸支部には、手摺の起立状態を固定するための固定手段が設けられ、軸支部にそれぞれ設けられた固定手段を連結具で連結し、当該連結具を操作することにより、手摺の起立状態の固定を解除可能としたトラック昇降ステップ。【選択図】図５
