摘要： When a conventional swivel working vehicle is constructed such that a real part of a swivel body is not extended beyond a traveling device in order to improve an operability at a small site, a balance weight must he significantly increased in weight so as to prevent falling and tumbling of a machine body. In the invention, left and right core metal projections of a crawler are laterally offset from a center line of the crawler and right and left lugs are formed on an outer peripheral surface of the crawler. The lugs are formed to assume the same shape on the right and left sides or laterally symmetrical shapes or occupy the same area on the right and left sides, and to be symmetrically shaped about a center of rotation of the swivel body between the left and right crawlers of the machine body.
