A paving machine for spreading, leveling and finishing concrete having a main frame, center module, bolsters laterally movably, and a crawler track associated with respective aft and forward ends of the bolsters. A bolster swing leg for each crawler track supports an upright jacking column. A worm gear drive permits rotational movements of the crawler track and the jacking column. A hinge bracket is interposed between each swing leg and a surface of the bolsters to enable pivotal movements of the swing leg. A length-adjustable holder engages the pivot pin on the hinge bracket and pivotally engages the swing leg. The holder permits pivotal motions of the swing leg in its length-adjustable configuration and prevents substantially any motion of the swing leg in its fixed-length configuration. A feedback loop cooperates with transducers keeping the crawler tracks position. The paving machine can be reconfigured into a narrowed transport configuration.
A swing leg assembly configured to be coupled to a paving machine configured to move in a paving direction for spreading, leveling, and finishing concrete into a form having a generally upwardly exposed, finished concrete surface and terminating in lateral concrete sides, the swing arm assembly comprising:
