Title
(EN) WHEEL ASSEMBLY CAPABLE OF MAINTAINING ENGAGEMENT WITH A RAIL HAVING AN UNEVEN PORTION THEREIN
(FR) ENSEMBLE ROUE SUSCEPTIBLE DE MAINTENIR SON ENGAGEMENT SUR UN RAIL POSSEDANT UNE PORTION IRREGULIERE
Abstract
(EN)
Wheel assembly (210) capable of maintaining engagement with a rail (140) having an uneven portion (160) therein. The wheel assembly includes a frame (215) adapted to pivot about a pivot axis (468) defined by the frame. At least one wheel (280, 300) is rotatably connected to the frame for traversing the rail. The wheel maintains engagement with the rail as the wheel traverses the uneven portion of the rail because the frame pivots about the pivot axis as the wheel encounters the uneven portion of the rail. Service tooling (130) may be suspended from the wheel assembly to service a nuclear reactor pressure vessel (10) located below the rail.
(FR)
Cet ensemble roue (210), susceptible de maintenir son engagement sur un rail (140) possédant une portion (160) irrégulière, comprend un châssis (215) conçu pour pivoter autour d'un axe (468) de pivotement délimité par le châssis. Au moins une roue (280, 300) est montée rotative sur le châssis aux fins de roulement sur le rail. La roue maintient son engagement sur le rail au moment où elle passe sur la portion irrégulière de celui-ci, car le châssis pivote autour de l'axe de pivotement lorsque la roue rencontre ladite portion irrégulière. On peut suspendre à cet ensemble roue un outillage d'entretien afin d'assurer l'entretien d'une cuve (10) sous pression de réacteur nucléaire placée en dessous du rail.
