ABSTRACT:
A gyratory compactor apparatus is provided that is adapted to interact with a mold that defines a mold axis. The gyratory compactor apparatus includes a frame that defines a frame axis and has a first mounting plate and a spaced-apart second mounting plate. A pivoted support is carried by the frame and capable of rotation in at least a first and a second rotational degree of freedom. A mold-engaging device is carried by the pivoted support and has a first carriage plate proximal the pivoted support and a second carriage plate axially spaced-apart from the pivoted support for receiving the mold therebetween. At least one actuator having a first end is carried by the frame and a second end is carried by the second carriage plate for imparting lateral translation to the second carriage plate relative to the frame axis. An associated method is also provided.
