Abstract
A railway anchor applicator for applying an anchor to a rail includes a frame configured for movement in a specified direction of travel along a track, and a workhead assembly movably mounted on the frame for movement toward and away from the rail. Also provided is an anchor receiving mechanism configured for movement between a first position receiving an anchor from an anchor input and a second position placing the anchor away from the anchor input. An anchor positioning mechanism moves between a retracted and extended position for positioning the anchor adjacent to the rail at either the field or gage side of the rail. An anchor clipping mechanism engages the anchor onto the rail by applying pressure on the anchor from the side of the rail and compresses the anchor between components of the anchor clipping mechanism so that compressive forces act on the anchor transversely across the rail.
