Crawler chain

摘要

An endless crawler chain capable of driving machinery across a surface. The endless crawler chain includes a plurality of first links interconnected with a plurality of second links to form the endless chain. Each of the second links has a pair of openings to accommodate adjacent first links. The openings allow the first links to move a predetermined amount in the longitudinal direction thereby allowing the chain to collapse while not under tension. The second links also include a pair of holes for rigidly attaching two halves of a crawler pad to each side of the second link. The entire crawler chain is so designed to be capable of being driven in an orbit to thereby propel the machinery across the surface.
