Machine for cutting pavement

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.
