Abstract

See full text

A blade set associated with jaws for demolition equipment used to break raiload 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 raised support rails associated with the bottom blade and the raised knife rail associated with the top blade have spaced recesses across their width which enhance the ability of the jaw sets to grab and retain work pieces. Additionally, the top blade has an outwardly tapering shape, such that upon completing a cutting operation a remaining portion of the severed railroad rail may be held and clamped by the jaw set for transportation or further processing. 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.
