The GOMACO?GT-3200 can be equipped with a front-mounted adjustable aggregate base mold to spread the base aggregate for the sidewalk. During the first pass, rock is placed on grade and an auger spreads the material, while three pan vibrators mounted to the mold start the compaction process. The base mold is equipped with two heavy-duty hydraulic cylinders that provide 14 inches (356 mm) of hydraulic lift for setting the grade depth below the track line and raising the mold for the paving pass.
