ABSTRACT:
A track frame in which stress concentration caused by a work load is avoided and that has increased strength. These are achieved by reducing the weigh of connection legs and providing sufficient welding length for joint surfaces for joining the connection legs. The track frame has a front and rear pair of left/right connection legs (61, 71) joined to a center frame (30) and side frames (7) to connect the center and side frames (30, 7). Each of the connection legs (61, 71) has a body part (62, 72) formed in a tubular shape, a center joint part (63, 73) formed at one opening edge of the body part (62, 72) and joined to the center frame (30), and a side joint part (64, 74) formed at the other opening edge of the body part (62, 72) and joined to a side frame (7). The center joining parts (63, 73) are flush with or projected from the upper surface of the center frame (30).
