More Information
Summary:A left fore leg (31) is constituted by an unitary tubular structure which is formed by integrally casting inner and outer joint portions (31A) and (31B), each in the form of a flare tube, along with an intermediate tubular portion (31C) by the use of a casting means. As a result, it becomes possible to form a longer welding bead around the inner joint portion (31A) on the side of the center frame, as well as around the outer joint portion (31B) on the side of the side frame, for enhancing the joint strength between the left fore leg (31) and the center frame (12) and between the left fore leg (31) and the side frame (22). Similarly, a left hind leg (32) is constituted by an unitary tubular structure which is formed by integrally casting inner and outer joint portions (32A) and (32B), each in the form of a flare tube, along with an intermediate tubular portion (32C) by the use of a casting means. A similar unitary tubular structure is fabricated by casting for a right fore leg and a right hind leg (34).
