Abstract:
Systems, methods, and non-transitory, machine-readable media for railway fastener removal are disclosed. A railway fastener extractor may be aligned with a railway fastener installed in a railway tie. The railway fastener extractor may be coupled with a frame assembly and a cylinder and slide assembly of a railway workhead so that the railway fastener extractor is suspended from the cylinder and slide assembly. The railway fastener extractor may be operated to extend opposing claws of the railway fastener extractor toward a railway fastener, and may be operated to selectively apply force to a linkage system to grip the railway fastener, the force being directed along a longitudinal axis. The force may be bifurcated and corresponding forces may be applied to move linkages and move the opposing claws to grip the railway fastener, and the railway fastener extractor may be operated to extract the railway fastener.
