  • Patent number: 6854552
    Abstract: A fork lift with a traverse travel system, wherein a pair of right and left front wheels (3) and a pair of rear wheels (4) can be steered to face sideways at a right angle relative to a body (2), the front wheel (3) is mounted to a turning member (27) installed on a mast (6) to be turnable around a vertical axis (26) and a rotating apparatus (40) is provided for the turning member (27), the front wheel (3) is operatively connected to a travel drive device (30) installed on the turning member (27), and the travel drive device (30) can also be rotated together with the turning member (27) when the front wheels (3) are steered sideways at a right angle and positioned outside of the outer surface of the mast. Thus, the mast (6) needs not be disposed unnecessarily forward of the front wheels (3) for the sake of the travel drive device (30), and the balance of the body in the longitudinal direction can be preferably kept without increasing its self weight.
