  • Patent number: 7338081
    Abstract: A left fore leg (31) is formed to shape by a casting means, integrating an inner joint portion (31A), an outer joint portion (31B) and an intermediate tubular portion (31C) into an unitary tubular structure. In this case, a joining end (31A1) of the inner joint portion (31A) as well as an outer joining end (31B1) of the outer joint portion (31B) is in the form of an open end of a rectangular shape. Accordingly, it becomes possible to cut the production cost of truck frame (11) and to form a longer welding bead around the outer periphery of the respective inner and outer joining ends (31A1) and (31B1) to enhance the joint strength between the inner joint portion (31A) and a center frame (12) as well as the joint strength between the outer joint portion (31B) and a side frame (22).
    Type: Grant

  • Patent number: 7338080
    Abstract: A vehicular body oscillating mechanism (31) is provided between a frame (3) of an automotive vehicular body (2) and a stabilizer (18) thereby to sway the vehicular body (2) arcuately in a rightward and/or leftward direction about a pivot point (A) between right and left rear wheels (6, 7) when the stabilizer (18) is set on the ground for a load handling operation. This means that, after the stabilizer (18) is set on the ground for a load handling operation, the vehicular body (2) can be swayed arcuately laterally in a rightward and/or leftward direction together with a load lifting mechanism (12). Therefore, in a load handling operation, the load lifting mechanism (12) can be adjusted in a lateral direction to dump lifted freight goods exactly on a specified unloading spot.
