Abstract

PROBLEM TO BE SOLVED: To provide a working boom installing structure which can easily and certainly install a working boom on a bracket furnished on a vehicle body. SOLUTION: Two coupling holes are provided for installing a working boom 6 on a bracket 5, wherein one of the holes serves direct coupling (by coupling pin 14) while the other indirect coupling (by coupling pin 15) through an intermediate metal fitting 12. Even if a component having a coupling hole is subjected to weld joining, machining, etc., and the coupling hole involves a positional error, the metal fitting 12 will absorb the error, which should facilitate the installing works of the boom 6 on the bracket 5 to lead to enhancement of the working effectiveness. Because the metal fitting 12 may be of a simple structure, the manufacturing processes can be suppressed and the costs be held reasonably.
