摘要： When a conventional swivel working vehicle is constructed such that a rear part of a swivel body is not extended beyond a travelling device in order to improve an operability at a small site, a balance weight must be significantly increased in weight so as to prevent falling and tumbling of a machine body. In the invention, a core metal projection (1a) of a crawler (1) is offset toward an outside of the machine body from a central position of the crawler (1) in a lateral direction, lugs (1b) formed right and left on an outer peripheral surface of the crawler (1) 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 assume point symmetrical shapes about a center of rotation of the swivel body (F) between the crawlers (1, 1) on the right and left of the machine body.
