The invention discloses an overhauling stepping ladder for a machine room. The overhauling stepping ladder is fixedly installed on an escalator truss and comprises a U-type support, a U-type pedal and a long shaft of which the two ends penetrate through two side face flat plates of the U-shaped support. The bottom of the U-type support is fixed to the escalator truss, through holes for penetrating of the long shaft are formed in the two side face flat plates of the U-shaped pedal, and the U-type pedal is movably connected with the U-type support through the long shaft. The rotatable retracting and stretching pedal structure is adopted, the overhauling stepping ladder is simple, stable and compact in overall structure, convenient to manufacture and install, low in cost, easy to operate and capable of achieving rotatable retracting and stretching and being overlapped with a vertical support after using, and is prevented from occupying a large internal space of the machine room, and safety is improved.
