Apparatus and method for shearing reinforced concrete piles and metal piles and crushing reinforced concrete piles

摘要

An apparatus (10) for shearing off reinforced concrete piles and metal piles, casing and conductor pipes, and crushing reinforced concrete piles has a frame (11) with first and second ends and a cutter blade (41) movably mounted on the frame driven by hydraulic rams (21) between a retracted position adjacent to the first end and an extended position toward the second end. An abutment gate (30) pivotally mounted and latched at the frame second end has vertically spaced first and second abutment surfaces (52A, 52B) and first and second horizontal shearing surfaces (53A, 53B) disposed in parallel vertically spaced relation defining an opening (51) therebetween through which the cutting edge (41B, 41C) of the blade passes. Removable crushing attachments (60A, 60B) allow crushing of concrete piles, and removable arcuate abutment attachments (54) accommodate cylindrical piles, casing and conductor pipes.
