<p>A guide pulley base for wire saw having a pair of main pulleys on the same plane, a pair of guidance pulleys in parallel to each other in such a way that each outer periphery of the guidance pulley is in contact with each parallel tangent line contacting with each outer periphery of each main pulley from the opposing side of the main pulleys, and further at need, a pair of second guidance pulleys, a pair of second main pulleys and an auxiliary pulley. The guide pulley base for wire saw is arranged between a wire drive unit and an object to be cut for guiding a cutting wire and smoothly turning the wire travel direction when an object to be cut such as ferroconcrete structure in a building, a bridge, a subway, etc. is cut off partially.</p> |
