ABSTRACT:
A lift crane in which the upper works is mounted on a platform that rides on a large diameter ring which is fixed to a generally square, planar and rigid frame. The frame is rigidly secured directly to the cross members which interconnect the crawlers of a crawler-transporter, with the securement being releasable by pin connections to permit the ring and its frame to be removed from the crawler-transporter and used as a fixed crane mounting pad.
