To provide a ladder apparatus for an elevator pit that solves problems in which when maintenance and inspection of a device placed in an elevator hoistway is performed, a stepladder dimensioned to be stored in a pit may not be sufficiently high depending on a location of the device, and especially for a main device, workability of the maintenance and inspection is poor if an access cannot be reliably made right in front of the main device, and it is dangerous to take an unusual position to perform the maintenance and inspection.SOLUTION: A ladder apparatus for an elevator pit comprises a support unit 2 fixed to a floor 1 of the pit and a ladder 3 detachably attached to the support unit 2. By fixing the support unit 2 of the ladder 3 to the floor 1 of the elevator pit beforehand, the ladder 3 can be reliably arranged in a standing condition at a necessary location.SELECTED DRAWING: Figure 2

    【課題】エレベータ昇降路に設置される機器を保守点検する際、ピットに保管しておける寸法の脚立は、機器の位置によっては高さが十分でないことがある。また、特に主要な機器については、その真正面に確実にアクセスできなければ保守点検の作業性が悪くなり、無理な姿勢で保守点検をしようとすれば危険でもある。【解決手段】エレベータのピット用はしご装置を、ピットの床1に固定されている支持部2と、支持部2に着脱自在に取り付けることができるはしご3を備えるものとする。エレベータのピットの床1に予めはしご3の支持部2を固定しておくことにより、必要な場所にはしご3を確実に立設することができる。【選択図】図2
