Abstract
A blade set associated with jaws for demolition equipment used to break railroad rails includes a bottom blade associated with a bottom jaw and a top blade associated with a top jaw, wherein the bottom jaw and the top jaw are rotatable relative to one another. The bottom blade includes two spaced-apart support rails separated by a cavity, while the top blade includes a single raised knife rail positioned and central to the cavity and rotatable toward the cavity. The top blade additionally may be marked with indicia, such as red paint, such that the machine operator may properly orient the top blade during a cutting operation to maximize safety. Additionally, the recesses may also be aligned and sized to engage the head and the foot of a rail such that tension and/or a bending moment is introduced between the head and foot of the rail.
