PROBLEM TO BE SOLVED: To suppress malfunction of an outrigger due to freezing, in a working machine with the outriggers.SOLUTION: There is provided a freezing preventive device 10 for outriggers 4 provided for a working machine, namely a crane. The crane comprises: the outriggers 4 each comprising a cylindrical frame 40; a sponson beam 41 inserted into the cylindrical beam 40, wherein the sponson beam 41 is configured to be relatively displaceable with respect to the cylindrical crane 40; and an engine 22 which is a source of power. The freezing preventive device comprises: a duct 11 which interconnects the circumference of the engine 22 and the insides of the respective cylindrical frames 40; and a fan 12 which is air blowing means disposed in the middle of the duct 11. The freezing preventive device is configured such that air surrounding the engine 22 can be supplied into the cylindrical frames 40 via the duct 11 by the fan 12.SELECTED DRAWING: Figure 3

    【課題】アウトリガを備える作業機において、凍結によるアウトリガの不具合を抑制する。【解決手段】筒状フレーム40と、筒状フレーム40に挿通される張り出しビーム41を有し、筒状フレーム40に対して張り出しビーム41を相対変位可能に構成したアウトリガ4と、動力源たるエンジン22と、を備える作業機たるクレーンの、アウトリガ4の凍結防止装置10であって、エンジン22の周囲と、筒状フレーム40の内部とを連通させるダクト11と、ダクト11の途中に配置される送風手段たるファン12と、を備え、ファン12によって、ダクト11を介して、エンジン22の周囲の空気を、筒状フレーム40の内部に供給可能に構成した。【選択図】図3
