LADDER AND MAINTENANCE FACILITY FOR STORAGE SHELF WITH THE SAME
PROBLEM TO BE SOLVED: To provide a ladder that a worker can easily go up and go down even if installed in a narrow temporary installation target space, and which can be easily installed, and a maintenance facility for a storage shelf with the same.SOLUTION: A ladder includes a plurality of steps 35 in a length direction of side rails between a pair of side rails 31, and is configured to be freely carried so as to be installed in an installation target space between a pair of structured. The pair of structures include a pair of support parts 10H for installation which are provided while being separated just by a preset distance longer than a distance between outer side faces in an arrangement direction in upper end portions of the pair of side rails 31. In upper ends of the pair of side rails 31, a pair of protruding parts 34H are provided which protrude to both outer sides in the arrangement direction of the pair of side rails 31. A protruding amount of the protruding parts 34H is set to such a protruding amount that the pair of protruding parts 34H are overlapped with the support parts 10H for installation at corresponding positions in a planar view in an attitude of a ladder 30 where the arrangement direction of the upper end portions of the side rails 31 are matched with an arrangement direction of the pair of support parts 10H for installation.
【課題】狭幅の仮設対象空間に設置しても作業者が昇降動作し易く、しかも架設が容易な梯子、及び、そのような梯子を備えた収納棚用のメンテナンス設備を実現する。【解決手段】一対の縦桟３１の間に横桟３５を縦桟長手方向で複数備え、一対の構造物の間の架設対象空間に架設すべく持ち運び自在に構成された梯子において、一対の構造物に一対の縦桟３１の上端部における並び方向での外側面間の距離よりも長い設定距離だけ離間させて設けられた一対の設置用支持部１０Ｈが設けられ、一対の縦桟３１の上端に、その一対の縦桟３１の並び方向での両外方側に突出した一対の突出部３４Ｈを備え、突出部３４Ｈの突出量が梯子３０の姿勢を縦桟３１の上端部の並び方向が一対の設置用支持部１０Ｈの並び方向に一致する姿勢としたときに、一対の突出部３４Ｈの夫々が、対応する位置の設置用支持部１０Ｈと平面視で重複する突出量に設定されている。【選択図】図４
