ABSTRACT:
A concrete paving machine which has a main frame and two hydraulic jacking columns at each end of the frame for raising and lowering the machine frame. Crawlers attached to the jacking columns move the paving machine in the travel direction. A paving kit is secured to the main frame and has a rigid center portion. Each terminal kit has an end frame secured to the center portion, an adjustable length support structure between the end frame and the slipform, and a hydraulic actuator. Spacers are interposed between the end frame and the slipform. A finishing pan is provided to finish the concrete surface. All replaceable components of the terminal are constructed and arranged so that they can be manually exchanged be one or two persons without removing the paving kit from the main frame and without needing the help of lifting equipment.
