ABSTRACT:
A machine for cutting concrete blocks especially continuously molded, highway dividing barriers of the New Jersey type, in a very fast and easy manner. The machine is mounted on a support base forming part of a powered truck-like vehicle and includes a primary extensible boom that is mounted on the support base so as to extend horizontally laterally thereof and be adjustably tiltable about its longitudinal axis. The machine also includes a secondary extensible boom that is mounted on the extensible end of the primary boom. Both of these booms extend in a same plane, and the secondary boom is downwardly tiltable about an axis transversal to both of the primary and secondary booms. A rotary, concrete-cutting saw assembly is mounted at the bottom end of the secondary boom. This assembly includes a saw blade that extends parallel to the plane in which said primary and secondary booms extend. Advantageously, the lateral orientation of the primary boom with respect to the front-to-rear axis of the vehicle may also be made adjustable.
