PROBLEM TO BE SOLVED: To provide an exclusive suspension tool which can dissolve problems that a fall prevention equipment worn and used in moving up/down in a pit becomes an obstacle, collides with stairs or an elevator circle on storing a rotary hook, and is caught midway to make the elevator circle come out, and a single tube support becomes unstable by vibration and is caught by heavy machinery. SOLUTION: This exclusive suspension tool has a support (4) which can be bent to fix a suspension position on a higher position at the center of an elevator circle (7) and the support (4) is rotatably and axially supported by a fixed base (2) which can be engaged with both right and left entrances.
