PROBLEM TO BE SOLVED: To provide an outrigger device capable of rotating a vertical outrigger between a storage posture and a grounding posture with man power without using power of a hydraulic cylinder even when the outrigger device itself is enlarged or mounted on a large truck.SOLUTION: An outrigger device 10 comprises: a hollow base 11; a lateral outrigger 12 fitted into the base 11 and overhanging sideway from the base 11 during operation; a vertical outrigger 20 connected to a side end of the lateral outrigger 12 through a manually rotatable rotation mechanism 4; and an assist mechanism 6 for applying posture holding force in a storage posture in which a grounding part of the vertical outrigger 20 is directed upward and a grounding posture in which the grounding part of the vertical outrigger 20 is directed downward, and assisting an operation of manually rotating the vertical outrigger to each posture with accumulated energizing force accumulating elastic energy.SELECTED DRAWING: Figure 2
【課題】アウトリガ装置自体の大型化や、大型トラックに架装搭載する場合であっても、油圧シリンダによる動力を用いることなく、格納姿勢と接地姿勢とのそれぞれに縦アウトリガを人力で回転させ得るアウトリガ装置を提供する。【解決手段】このアウトリガ装置10は、中空のベース11と、ベース11内に嵌装されるとともに作業時にはベース11から側方に張り出される横アウトリガ12と、横アウトリガ12の側端に手動で回転可能な回転機構4を介して連結される縦アウトリガ20と、縦アウトリガ20の接地部が上方を向く格納姿勢と縦アウトリガ20の接地部が下方を向く接地姿勢とにおける姿勢保持力を付与するとともに相互の姿勢に手動で回転させる作業を弾性エネルギーを蓄積した蓄勢力により補助する補助機構6とを備える。【選択図】図2
