PROBLEM TO BE SOLVED: To provide a simple crane configured so that a wire rope hardly contacts a suspended load even when a bracket is made turnable.SOLUTION: A simple crane main body 40 comprises a base part support post 41 which can be attached with a clamp 42 to a building frame member 31 of a Vita temporary scaffold 30. On the base part support post 41 is pivotally supported a bracket 43 by a support shaft 44 to be freely turnable in a horizontal surface. To a front part of the bracket 43 is firmly bonded a load-side pulley attachment clasp, with a cargo-side pulley 47 hung and suspended. To an upper frame of the bracket 43 is fitted a front extension portion 48, and to a front end of the front extension portion 48 is fitted a guide rope attachment clasp. At a lower end part of a stud of the bracket 43, to the vicinity of an extension line of the support shaft 44 is fitted a winch-side sheave 57. A wire rope 81 of the winch 80 arranged below the winch-side sheave 57 is wound around the load-side pulley 47 through the winch-side sheave 57, and a suspension hook 82 at a tip thereof is allowed to hang down.SELECTED DRAWING: Figure 2
