構造。 In a backhoe constructed by installing a hydraulically operated working machine section so as to be rotatable in the longitudinal direction of the machine body, an upper plate 4a and a lower plate 4b are connected to the upper and lower sides of both side plates 3a and 3b of a boom A supported at the base of the machine body. An appropriate number of reinforcing plates 5a, 5b are installed inside the boom A, which is a cavity with a cross-sectional opening, and a large number of oil pipes 6 are connected to the boom so that they can be clamped to the reinforcing plates 5a, 5b. A characteristic feature is that the oil pipes 6 are installed in the cavity of the boom A, project from the front and rear ends of the boom A, and from the intermediate portion of the upper plate 4a, and are connected to each part via the connectors 7. The piping structure of the boom.
