Abstract
A portable wire saw for cutting materials such as stone, concrete, asphalt and the like such as highway lane barriers. The portable wire saw includes a frame having a base on which is mounted a power source. Attached to the base is a plurality of wheels for easy portable movement of the wire saw. At least one of the wheels also provides a pivot point for the frame so that the wire saw can be pivoted between a cutting position and a non-cutting position. The power source drives a wire saw blade carried on a triangular support structure consisting of two pulleys and a drive wheel. The drive wheel is operably connected to the power source. The position of the pulleys is capable of being adjusted relative to the drive wheel. In a preferred embodiment the triangular support structure is arranged in a vertical orientation with the upper pulley functioning to keep the return path of the wire saw blade from having to pass through the material being cut.
