    • The invention provides roller rail clamp apparatus for use in lifting a rail for operations such as replacement of ballast or resurfacing of a railway. The apparatus (1) comprises parallel pairs of spaced-apart lift roller assemblies (7-10) mounted to a support for positioning a pair for clamping to a rail of the track, each the lift roller assembly comprising at least one pair of rollers (33, 35), wherein each the roller of a roller pair rotates on an axis in an essentially vertical plane adjacent a rail and the rollers are on opposite sides of a rail when a lift roller assembly is clamped thereto with the head (42) of the rail releasably retained upwardly of flanges (48, 51) at the lower ends of the rollers; means (5) for adjustably connecting the apparatus to a carrier thereof; a lift mechanism (14) for adjusting the vertical position of the support relative to the carrier of the apparatus; and a tilt mechanism (17) for applying torque about a horizontal axis to linkage between members of a pair of lift roller assemblies.

    • La invencion proporciona un aparato de abrazadera de rodillo de anclaje al carril para utilizarse en el levantamiento de un carril en operaciones tales como el reemplazo de balasto o la reparacion de la capa de rodadura de una via ferrea. El aparato (1) comprende pares paralelos de ensambles de rodillo de suspension separados (7-10) montados en un soporte para la colocacion de un par de sujecion a un carril de la guia de deslizamiento, cada ensamble de rodillo de suspension comprende al menos un par de rodillos (33, 35), en donde cada uno de los rodillos de un par de rodillos gira sobre un eje en un plano esencialmente vertical adyacente a un carril y los rodillos se encuentran sobre lados opuestos de un carril cuando un ensamble de rodillo de suspension se sujeta al mismo con la parte superior (42) del carril liberablemente retenida de manera vertical en los rebordes (48, 51) en los extremos inferiores de los rodillos; medios (5) para conectar de manera ajustable el aparato a un vehiculo del mismo, un mecanismo de suspension (14) para ajustar la posicion vertical del soporte con relacion al vehiculo del aparato; y un mecanismo de inclinacion (17) para aplicar fuerza de torsion alrededor de un eje horizontal al enlace entre los miembros de un par de ensambles de rodillo de suspension.
