Abstract:
A machine including a powered truck-like vehicle having a support base and an apparatus mounted on the base for cutting pavement, said apparatus comprising:two spaced-apart cylindrical booms, each boom having one end pivotally mounted on the base and an opposite end; tilting means mounted on said base for tilting each boom about its one end in a vertical plane; a supporting bar mounted on the opposite ends of the cylindrical booms so as to be free to rotate about the cylindrical booms within a plane perpendicular to the cylindrical booms; an extendible, ground-contacting leg at each end of the supporting bar for stabilizing the apparatus; a rail-structure-holding head slidably mounted on each cylindrical boom so as to slide along the cylindrical boom and to be free to rotate about the cylindrical boom within a plane perpendicular to said cylindrical boom; sliding means for sliding separately each head along the corresponding boom; an elongated main rail; main rail mounting means for mounting the main rail on said heads and for rotating the main rail about a longitudinal axis parallel to said elongated main rail; a saw carrier mounted on the main rail; displacing means for moving the saw carrier along the main rail in a first direction parallel to the longitudinal axis; a motorized saw mounted on the saw carrier; and moving means for moving the saw on the saw carrier in a second direction perpendicular to said longitudinal axis.
