PROBLEM TO BE SOLVED: To provide a crane installation structure which enables installation of a crane with higher performance than conventional cranes without specially reinforcing a framework foothold.SOLUTION: A crane installation structure 1 includes: a rail member 2 fixed to a building frame; a base member 3 supported by a framework foothold; a lifting frame member 4 which can be moved up or down relative to the rail member 2 and the base member 3; and a mast member 5 supported by the lifting frame member 4. The mast member 5 has a mast body 51 and a spherical part installed at a lower end of the mast body. The lifting frame member 4 includes: a pedestal having a spherical recessed part which supports the spherical part of the mast member 5; and a mast insertion part into which the mast member 5 is inserted.SELECTED DRAWING: Figure 1
