PROBLEM TO BE SOLVED: To provide a stair lifting device and a stair lifting method of a heavy load in which the heavy load can be carried via a narrow stair with a loop back.SOLUTION: A stair lifting device 1 according to the present invention is configured to lift and carry a heavy load 10 over a stair 100. The stair lifting device includes two portal type structures, a rail 5 provided by connecting top parts of two portal type structures, a trolley 7 provided to the rail 5, and a portal type auxiliary fixture 50 provided in a trolley 7 and having a chain block 8 for lifting a heavy load 10. Also, the present embodiment includes base parts 11a, 11b mounted with the heavy load 10, rollers 12a-12d provided in the base parts 11a, 11b, and legs 13a, 13b attached to the base part 11b. The heavy load 10 is lifted by the portal type auxiliary fixture 50 and moved horizontally, and is held on the stair 100 by the rollers 12a-12d and the legs 13a, 13b except when moved.

    【課題】狭く、かつ折り返しのある階段を経由して重量物を運搬することができる重量物の階段揚重装置及び階段揚重方法の提供。【解決手段】本発明に係る階段揚重装置1は、重量物10を、階段100上を吊り上げて運搬するものであり、2つの門型構造体、2つの門型構造体の頂部を結合して設けられたレール5、レール5に設けられたトロリ7、及びトロリ7に設けられ、重量物10を揚重するチェーンブロック8を有する門型雇50を備えている。また本実施形態は、重量物10が搭載される台部11a,11bと、台部11a,11bに設けたローラ12a〜12dと、台部11bに取り付けた脚13a,13bとを備えている。重量物10は、門型雇50により吊り上げられて水平方向に移動させられ、移動時以外はローラ12a〜12dと脚13a,13bとで階段100上に保持されるようになっている。【選択図】図1
