ABSTRACT:
A spike removing system for removing deeply embedded spikes from railroad tracks. The inventive device includes a housing having an open end, an upper hydraulic cylinder attached within an upper portion of the housing, a lower hydraulic cylinder having a plurality of opposing first jaws and second jaws pivotally attached thereto, and a plunger head attached to the lower hydraulic cylinder for closing and separating the opposing first jaws and second jaws with respect to one another. The first and second jaws are preferably S-shaped and include a channel for allowing the opposing jaw to slidably move with respect to the other jaw. The jaws project downwardly when closed upon a spike, thereby digging into the tie to ensure proper engagement with the head of a deeply embedded spike.
