<p>PROBLEM TO BE SOLVED: To provide an outrigger connection mechanism capable of connecting an outrigger with a carrier frame by certainly inserting a connection pin even when an error occurs in manufacturing accuracy of a connection part between the outrigger and the carrier frame.SOLUTION: An outrigger pin 72 is provided at an upper part of an outrigger side plate 71, and an outrigger pin hole part 73 is provided at a lower part of the outrigger side plate 71. In addition, a concave pin engaging part 42 the upper part of which is opened is provided at an upper part of a carrier frame side plate 41, and a carrier frame pin hole part 44 is provided at a lower part of the carrier frame side plate 41. At a state that the outrigger pin is engaged into a bottom of the pin engaging part, the outrigger pin hole part comes to a lower part than the carrier frame pin hole part. Then, positions of the outrigger pin hole part and the carrier pin hole part are matched to each other by lifting an outrigger while engaging the outrigger pin into the pin engaging part, and the outrigger is connected with a carrier frame by inserting a rod pin and a tube pin into the outrigger pin hole part and the carrier frame pin hole part.</p> |
