A plate retainer apparatus is provided for use on a railroad track with a tie exchanger having a main frame, the apparatus configured for gripping and retaining rail tie plates to a rail during a rail tie exchange process. The plate retainer apparatus includes a plate retainer workhead constructed and arranged for movement independent of that of the main frame. Included on the workhead is a pair of workhead modules, each module associated with a rail of the track and configured for retaining a single tie plate associated with a target tie at a time. Each workhead module is movable relative to the main frame independently of each other.

Rail plate retainer for use with rail tie exchanger

A rail tie plate retaining workhead is provided for use in conjunction with a rail tie replacement machine moving along a railroad track having a pair of rails. The workhead includes a workhead frame configured for movement along the track relative to the rail tie replacement machine, and a pair of plate retaining frames, each frame associated with a respective one of the rails, and being connected to the workhead frame. Each plate retaining frame has at least one rail guide wheel connected to the retaining frame using a fluid powered cylinder, the wheels vertically reciprocating between an extended position, in which the workhead is raised to a travel position, and a retracted position, in which the workhead is lowered to a working position in operational relationship with at least one targeted rail tie plate.

Rail plate retainer with stabilized gripping jaws for use with rail tie exchanger

A rail plate handling device is provided for removing and reinstalling rail tie plates located on rail ties on a railroad track, includes a frame configured for movement relative to the track, at least one tie plate gripping assembly mounted to the frame, the assembly configured for grasping a selected tie plate at the front and rear edges between an adjacent one of the at least one raised rail raised from the operational position supported by the selected tie plate and the associated tie in the operational position upon which the plate was resting, each gripping assembly including a pair of opposing gripping jaws which are configured for controlled reciprocation in a direction parallel to the rails along a guide bar, the guide bar being slidable with the gripping jaws and the selected plate, relative to the frame.
