The diesel Crafco Patcher is a double boiler that is digitally controlled to assure that material temperatures are held within specification ranges at all times. A swivel material delivery chute makes placing material fast and easy. To clean out, load the machine with dry aggregate – run agitator and empty – it’s that easy. All machines are equipped with a safety shutoff on the lid to prevent injury during operation. Available in a one ton (Patcher I) and two ton (Patcher II) configuration. These machine are specifically designed to heat and apply TechCrete and PolyPatch patching material.
