<p>The device comprises, for each wheel (11), an oscillating arm (5) on which are mounted the portion (7) of the rail for the passage of the vehicle above the reconditioning lathe, and two rollers (14) for driving the wheel, the said arm (5) being integrally connected to a carriage (1) which slides transversely. The displacements of the arm (5) and of the carriage (1) are coordinated so that the rollers (14) are in contact with the wheel when the rail (7) is retracted, and vice versa. The device can comprise an integrated towing system, using the same drive element as that serving for the rotation of the rollers (14), the operation of which is dependent upon the position of the carriage (1). <IMAGE></p> |
