ABSTRACT:
A railway track working machine is equipped with a device for blocking the suspension of its axles, which device comprises, for each axle box a movable support sliding in a vertical guide fixed to the machine chassis and vertically displaced by a rod of a jack. Restoring springs ensure that the movable support bears against the rod of said jack. The movable support comprises a vertical stop, a transverse stop and two longitudinal stops intercepting during and at the end of the travel of the jack bearing members integral with the axle box in order to immobilize the latter in the vertical, transverse and longitudinal directions with respect to the chassis. This device is suitable for machines whose tools are generators of reaction forces which are capable to displace the machine chassis with respect to the railway track in the three aforementioned directions.
