To provide an outrigger device in which plural actions required for storing and installing the outrigger device can be operated by a single actuator.SOLUTION: An outrigger device 9 comprises: a base end side arm 93; a nested tip side arm 95 with its base end part pivoted to a tip of the base end side arm; and a lateral outrigger cylinder 36 of which an end part on a cylinder rod 36b side is supported in a position near a tip of the tip side arm 95, and of which an end part on a cylinder tube 36a side is supported by a horizontal shaft in a freely rotatable manner in a position near the tip of the base end side arm 93. Further, the outrigger device is constituted such that the tip side arm 95 is elongated or contracted, when only a turning action of the tip side arm is restricted by a first attitude holding means, according to elongation/contraction operation of the lateral outrigger cylinder 36, whereas the tip side arm 95 performs a turning operation, when only the elongation/contraction operation of the tip side arm 95 is restricted by a second attitude holding means.SELECTED DRAWING: Figure 6
【課題】 アウトリガ装置の格納、設置動作に必要な複数の動作を、単数のアクチュエータで賄うことが可能な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9は、基端側アーム93と、その先端部に、基端部が枢支された入れ子状の先端側アーム95と、先端側アーム95の先端寄りの位置にシリンダロッド36b側の端部が支持され、基端側アーム93の先端寄りの位置にシリンダチューブ36a側の端部が水平な軸回りに回転自在に支持された横アウトリガシリンダ36とを備える。そして、横アウトリガシリンダ36の伸縮作動によって、第1の姿勢保持手段で先端側アームの回動動作のみを拘束したときは、先端側アーム95が伸縮動作し、第2の姿勢保持手段で先端側アーム95の伸縮動作のみを拘束したときは先端側アーム95が回動動作するように構成されている。【選択図】図6
