Claim Text:
1. A platform for accessing a hydraulic machine via a suction tube, this hydraulic machine belonging to an installation for converting hydraulic energy into mechanical or electrical energy, or reciprocally, the platform comprising: load-bearing longitudinal beams configured to slide along a longitudinal axis to enter an opening of the suction tube and including a first extremity that is configured to be immobilized in a first seat of the suction tube; and floor elements placed on the load-bearing longitudinal beams, at least one of the floor elements being articulated about axes substantially parallel to the longitudinal axis and being movable in rotation about the axes substantially parallel to the longitudinal axes between a folded configuration and a deployed configuration in which they define at least a portion of a floor of the platform, wherein lower surfaces of the floor elements carry the longitudinal beams including the first extremity configured to be selectively fitted into the first seat of the suction tube; the first extremity of the longitudinal beams includes a first automatic engagement mechanism; the first automatic engagement mechanism comprises a first rod and first elastic loading means pushing the first rod towards the first seat of the suction tube; and the first rod is mounted tiltingly about an axis substantially perpendicular to a thickness of the longitudinal beams and in that a movement of the longitudinal beams in a direction normal to the floor tilts the first rod such that the first rod comes out of the first seat.
