PROBLEM TO BE SOLVED: To provide an outrigger device to be used for a high lift work device equipped with telescopic columns.SOLUTION: The outrigger device to be mounted on each column (4) of the high lift work device, having a main leg (4a) and a telescopic leg (4b), includes a supporting member (7) to be attached to the column (4), and an auxiliary leg (10) provided on the supporting member via an opening/closing mechanism (9). The auxiliary leg (10) can be freely opened/closed between a leg closing position and a leg opening position by the opening/closing mechanism (9). Between the main leg (4a) of the column (4) and the supporting member (7), a slide guide mechanism (11) is provided in which the supporting member (7) is movably connected to the main leg (4a) in its longitudinal direction and connection means (12) is provided via which the telescopic leg (4b) of the column (4) and the supporting member (7) are connected to each other. When the telescopic leg (4b) is telescopically moved, the supporting member (7) is moved following and accompanying it. |
